Abstract:
The aim of this study was to determine if the changes in plasma insulin, glucose (GLU), fructosamine (FRUCT), adrenocortical hormone (ACTH), and cortisol (CORT) concentrations in mares of different ages were substantial enough to indicate the need to also establish specific reference intervals for pregnant Spanish Purebred mares with a heterogeneous body conditional score (BCS). A total of 45 mares were used in the study, which were classified according to age into 24 <10 years (from 4 to 9 years) and 21 >10 years (from 10 to 18 years). According to the BCS, mares <10 and >10 years were distinguished into three groups as follows: underweight (BCS < 4–5; n = 8), moderate (BCS = 6–7; n = 8), and overweight (BCS = 8; n = 8) (BCS < 4–5 (n = 7), BCS = 6–7 (n = 7), and BCS = 8 (n = 7)), respectively. The main results of this study were that (I) circulating insulin, GLU, FRUCT, ACTH, and CORT concentrations were altered throughout the whole duration of pregnancy in mares; that (II) aging and BCS significantly affected insulin, ACTH, and CORT changes; and that (III) ACTH-CORT significantly correlated with insulin, FRUCT, and GLU. The results may have implications for health and disease and warrant future prospective investigations on the bidirectional interaction between insulin and the hypothalamus–pituitary–adrenal (HPA) axis in equine species, affecting the GLU and FRUCT profile through the entire physiological pregnancy.

Abstract:
A banana tem sido comumente indicada como uma boa fonte de frutooligossacarídeos (FOS), que são considerados componentes funcionais de alimentos. Contudo, diferenças significantes em suas quantidades têm sido referidas na literatura. Portanto, uma parte do trabalho foi destinada à identificação e quantificação de FOS durante o amadurecimento de cultivares de bananas pertencentes aos grupos genômicos mais comumente cultivados no Brasil. Considerando as diferenças de cultivar, estágio do amadurecimento e metodologia usada para análise de FOS, os conteúdos dos açúcares foram analisados por cromatografia líquida de alta performance (HPAEC-PAD) e cromatografia a gás (CG-MS). Uma pesquisa inicial entre oito cultivares no estágio maduro, mostrou acúmulo de 1-cestose, primeiro membro da série de FOS, em todas elas (quantidades entre 297 e 1600 &#181;g/g M.S). A nistose, o segundo membro, foi detectado somente na cultivar Prata. Com bases nestes dados, foram escolhidas cinco cultivares, para que fossem analisadas durante todo o amadurecimento. Os resultados mostraram uma forte correlação entre a chegada a um nível específico de sacarose (~200 mg/g M.S) e a síntese de 1-cestose. Em uma segunda fase, os níveis de sacarose e FOS total foram quantificados em diferentes fases de amadurecimento de banana Prata, armazenada em temperatura ambiente e em baixa temperatura. As supostas enzimas envolvidas em sua síntese também foram avaliadas. Para explorar a possibilidade da invertase ser responsável pela atividade de frutosiltransferase em banana, foi medido o efeito do inibidor Piridoxal HCl, os níveis de concentração do substrato e as atividades de hidrólise e transglicosilação, e o efeito do tempo no estudo cinético da enzima. A baixa temperatura atrasou todos os eventos analisados por 15 dias e os níveis de sacarose tiveram um pequeno aumento, porém constante, enquanto a banana estava armazenada ao frio, e uma rápida elevação no final do amadurecimento. Foi detectado FOS total desde o primeiro dia pós-colheita, enquanto que a 1-cestose permaneceu indetectável até os níveis de sacarose atingirem aproximadamente 200 mg/g M.S., em ambos os grupos. Os níveis de sacarose e FOS total foram ligeiramente maiores em bananas armazenadas em baixas temperaturas do que em frutos controle. Em ambas as amostras os níveis de FOS total foram maiores que de 1-cestose. Os perfis de carboidratos por HPLC e TLC sugeriram a presença de neocestose, 6-cestose e bifurcose. A enzima supostamente responsável pela atividade de transglicosilação em banana parece ser a invertase. Contudo, os altos níveis de sacarose encontrados em banana armazenadas em baixa temperatura, poderiam ser resultado de várias mudanças de enzimas degradativas e biossíntéticas, como sacarose-sintase (SuSy), sacarose-fosfato-sintase (SPS), invertase e outras, uma vez que a sacarose possui um papel central, direta ou indiretamente, em diversas vias do metabolismo de carboidrato em banana. Assim, na última parte do trabalho foram analisados o acúmulo de sacarose e a síntese e atividade de enzimas sintéticas, hidrolíticas e fosforolíticas, importantes no metabolismo de amido-sacarose, durante o amadurecimento de banana Prata nos dois tratamentos. A baixa temperatura não danificou os frutos, aumentando a vida de prateleira deles. As amostras do frio apresentaram pequeno aumento no nível de degradação de amido e um acréscimo de 20 % na sacarose acumulada durante o amadurecimento. Foi verificado o atraso na produção de etileno, CO2, e no início de degradação de amido durante o acondicionamento ao frio, concomitante ao atraso no pico de atividade de &#945;-amilase. O atraso no climatério também manteve alta a atividade e síntese protéica de SuSy durante o armazenamento a frio, que declinaram após a retirada do frio, como no controle. As enzimas &#946;-amilase, fosforilase (forma citosólica e plastidial) e SPS reagiram positivamente, sofrendo uma indução positiva na síntese e atividade enzimática durante o armazenamento ao frio, que poderia ser parte do mecanismo necessário para os maiores níveis de açúcares e para o processo de tolerância do fruto à baixa temperatura.<br>Banana has been currently indicated as a good source of fructooligosaccharides (FOS), which are considered to be functional components of foods. However, significant differences in their amounts in bananas have been observed in the literature. So, a part of this work aims to identify and quantify FOS during ripening in different banana cultivars belonging to the most common genomic groups cultivated in Brazil. Considering that these differences can be due to cultivar, stage of ripening, and the methodologies used for FOS analyses, sugar contents were analyzed by high performance anion exchange chromatography pulsed amperiometric detection (HPAEC-PAD) and gas chromatography- mass spectrometry (GC-MS). An initial screening of eight cultivars in a full-ripe stage showed that 1-Kestose, the first member of the FOS series (amounts between 297 and 1600 &#181;g/g of D.M), was accumulated in all of them. Nystose, the second member, was detected only in Prata cultivar. Five of the cultivars were analyzed during ripening, and a strong correlation could be established with a specific sucrose level (~200 mg/g of D.M.), which seems to trigger the synthesis of 1-Kestose. In a second part of this work, the levels of sucrose and total-FOS were quantified in different phases of banana Prata ripening stored at ambient and low temperature. The supposed enzymes involved in their synthesis were also evaluated. To explore the possibility that invertase could be responsible for the fructosyltransferase activity in banana, we measured the effect of the inhibitor Pyridoxal HCl, the level of substrate concentration on both hydrolyze and transglycosylase activity in the same protein extract and the effect of time on kinetic study of the enzyme. The cold temperature delayed all the analyzed events for 15 days and sucrose levels increased low, but constantly, while banana were stored at low temperature and had a burst when it increased. Total-FOS were detected in the first days after harvest, while 1-kestose remained undetectable until the sucrose levels were around 200 mg.g (dry weight), in both groups. Total-FOS and sucrose levels were higher in banana stored at low temperature than in control. In both samples total-FOS levels were higher than 1-kestose. The carbohydrate profiles by HPLC and TLC suggest the presence of neokestose, 6-kestose and bifurcose. The enzyme supposed to be responsible for the transglycosilation activity in banana, seems to be an invertase. However, the higher sucrose levels found in banana stored at low temperature could be result of several changes in biosynthetic and degradative enzymes, such sucrose-synthase, sucrose-phosphate-synthase, invertase and others, once that sucrose plays a central role in a lot of direct and indirect carbohydrate pathways in banana fruits. So, in the last part of this work, we analyzed the sucrose accumulation and synthesis and activity of synthetic, hydrolytic and phosphorolytic enzymes that are important in the starch-sucrose metabolism during ripening of banana Prata stored at ambient and low temperature. The levels of starch degradation and sucrose accumulation (around 20% over) showed high levels in cold fruits as compared with control, during the ripening. The cold temperature delayed the ethylene and CO2 production, and the beginning of the starch degradation, concomitantly with a delay in the profile of &#945;-amylase synthesis and activity. The late climateric also maintained the high synthesis and activity of SuSy during the cold storage that decreased just after ending the cold exposure. The &#946;-amylase, phosphorylase (plastidial and citossolic forms) and the SPS enzymes showed a positive induction in the both activity and synthesis of protein during the cold storage. It could be important to the higher sugars levels showed at low temperature and that could contribute to the process of cold resistance in banana fruit.

<p>Hensikten med denne masteroppgaven i Innovation Management, har vært å klargjøre de ulike faktorene som har påvirket prosessen med å få til eksport av frukt og grønnsaker fra Kroatia til Skandinavia, og mer konkret fra Erdut kommune i Øst-Slavonia til COOP Norge.</p><p>I kapittel tre har vi beskrevet relevant teori som belyser fagfeltet som er omhandlet i denne oppgaven.</p><p>Siden det har manglet sekundærdata som beskriver antall gårdsbruk, produkter som dyrkes, tilgjengelig teknologi, bruk av sprøytemidler og lignende, har vi gjennomført undersøkelser som beskriver situasjonen og potensialet for eksport fra regionen. Disse undersøkelsene ble gjennomført sammen med lokale partnere.</p><p>I tillegg gjennomførte vi to eksperimenter for å se om personell og produksjonsprosessen kunne levere den kvaliteten som markedet og kundene krevde . Disse eksperimentene ble mulige ved at COOP Norge kunne delta aktivt som en krevende og kompetent kunde i denne fasen av prosjektet. Begge eksperimentene avslørte til dels store avvik fra kundens krav. Det ble derfor iverksatt to kvalitative undersøkelser blant de lokale produsentene, representanter fra lokalt næringsliv, og våre lokale partnere i området. Hensikten med denne kvalitative undersøkelsen var å finne årsakene til leveringsproblemene og prøve å finne strategier for å få til gode leveranser i framtida.</p><p>Disse dataene ga oss relevant informasjon om årsakene til problemene og identifiserte kritiske suksessfaktorer for videreføring.</p><p>Eksperimentene viste at eksport av frukt og grønt fra dette området ga omlag den dobbelte inntjeningen av tilsvarende leveranser til det lokale markedet.

Dette for å kunne beskrive marked og markedskrav og spille en aktiv rolle i å utforme viktig detaljer og påvirke utviklingen av verdikjeden .</p><p>- Opplæring av nøkkelpersonell er viktig både for å endre mentale bilder og for å få introdusert nye arbeidsmetoder som er kritiske for å få til god kvalitet.</p><p>- For å styre disse to faktorene er det viktig å få på plass en lokal, sterk og kompetant prosjektleder. Nøkkelen er å finne en person som har evnen til å lede i en god balanse mellom transaksjons- og transformasjonsbasert lederskap. Prosjektledelsen trenger å involvere og motivere produsenter, men samtidig må de være i stand til å intervenere når det er nødvendig å korrigere prosessen (stoppe aktiviteter som har negativ effekt og holde et sterkt fokus på riktig sortering, pakking og kvalitetskontroll)</p><p>- Introdusere et system for sporbarhet og visuell kontroll slik at alle produsentene kan identifiseres og knyttes direkte til de leverte produktene. Hensikten er ikke hovedsakelig kontroll, men for å kunne skape en læringsarena og drive kompetanseutvikling.</p><p>- Prosjektet som dette der de gamle mentale bildene blir utfordret og må erstattes av nye, vil alltid trenge tid til å modnes og utvikles. Det er derfor viktig å ikke undervurdere tidsaspektet samt legge vekt på tett oppfølging og tilrettelegging i tidlige faser.</p>

Thesis (MScAgric)--Stellenbosch University, 2013.<br>ENGLISH ABSTRACT: Fruit size and the integrity of the rind are key components that determine the value of a citrus fruit. The application of 2,4-dichlorophenoxy acetic acid (2,4-D) to reduce splitting, a physiological disorder which entails cracking of the rind as well as to increase fruit size was conducted on three different split-susceptible mandarin and two split-susceptible orange cultivars. Treatments were applied directly after the physiological fruit drop period, as well as in January and February at 10 mg·L-1, alone or in combination with calcium (Ca), potassium (K) or gibberellic acid (GA3). Application of 2,4-D directly after physiological fruit drop, either alone or in a tank-mix with K, consistently reduced the number of split mandarin fruit, with later applications in January and February generally being ineffective. Post physiological fruit drop application of 10 mg·L-1 2,4-D significantly increased growth rate (mm.day-1) of all the mandarin cultivars, resulting in increased fruit size. Differences in sensitivity of cultivars to 2,4-D were evident, with the January application reducing the splitting in ‘Midknight’ Valencia. However, all the 2,4-D treatments reduced the fruit growth rate of the orange cultivars. The 2,4-D treatments, in terms of splitting, increased rind thickness, -strength and -coarseness of ‘Marisol’ Clementine, throughout fruit development. In addition fruit diameter and –length increased to such an extent that the fruit shape was altered (reduced d/l-ratio), reducing the potential of the rind to crack and the fruit to split, however rind coarseness of treated fruit was also increased. There were no major negative side effects on internal and external fruit quality, except for a possible reduction in juice content (%). Therefore, 10 mg·L-1 2,4-D can be applied directly after physiological fruit drop on ‘Marisol’ Clementine and ‘Mor’ mandarin to reduce fruit splitting.<br>AFRIKAANSE OPSOMMING: Vruggrootte asook die integriteit van die skil is belangrike aspekte in die bepaling van ʼn sitrusvrug se waarde. Die toediening van 2,4-dichlorofenoksie asynsuur (2,4-D) om vrugsplit, 'n fisiologiese defek wat tot die kraak van die sitrusskil lei, te verminder is getoets op drie mandaryn- en twee lemoenkultivars. Hiermee saam is die potensiaal van 2,4-D om vruggrootte te verbeter ook geëvalueer. Die 2,4-D behandelings is direk na die fisiologiese vrugval periode toegedien, asook in Januarie en Februarie, teen 10 mg·L-1, alleen of in kombinasie met kalsium (Ca), kalium (K) of gibberelliensuur (GS3). Al die mandarynkultivars het ʼn vermindering in die totale aantal gesplete vrugte getoon indien die 2,4-D (enkel of in kombinasie met K) toegedien was direk na fisiologiese vrugval. Suksesvolle behandelings het ook 'n toename in vruggrootte tot gevolg gehad. Toediening van behandelings in Januarie en Februarie was oor die algemeen oneffektief. Verskille in kultivar sensitiwiteit teenoor 2,4-D is gevind, met vrugsplit in ‘Midknight’ Valencia wat verminder was deur die Januarie toediening van 2,4-D. Al die 2,4-D behandelings het vruggrootte van die lemoenkultivars verlaag. Daar is bevind dat die 10 mg.L-1 2,4-D, enkel of in kombinasie met K, ‘n toename in beide skildikte en –sterkte van ‘Marisol’ Clementine teweeg bring asook ʼn growwer skil. Behandelings met 2,4-D het vrugdeursnee en –lengte laat toeneem, wat ʼn verandering in vrugvorm tot gevolg gehad het, tot so ʼn mate dat vrugte minder geneig was om gesplete te wees. Behalwe vir ʼn moontlike verlaging in die sapinhoud (%) van vrugte, was daar geen noemenswaardige negatiewe effekte op interne en eksterne vrugkwaliteit nie. Die toediening van 10 mg.L-1 2,4-D direk na fisiologiese vrugval kan dus aanbeveel word op mandaryn kultivars wat geneig is tot vrugsplit.<br>The Citrus Academy

Thesis (MscAgric (Horticulture))--University of Stellenbosch, 2009.<br>ENGLISH ABSTRACT: For many apple (Malus domestica Borkh.) and pear (Pyrus communis L.) cultivars, attractive colour is essential to their profitability on export markets. This study focuses on problems related to poor green colour of ‘Granny Smith’ apples and insufficient red colour of bi-coloured pear cultivars. ‘Granny Smith’ apples often suffer from poor green colour. Green colour of fruit from various orchards was already found to differ midway through fruit development, with these differences being carried through to harvest. In a trial where nitrogen (N) fertilisers were applied using different forms at different times, there was no improvement in green colour. In another trial, artificial shading was applied to fruit only during their early development. Fruit that were shaded during this time were less green at harvest than unshaded fruit. Additional N applications may only improve colour where a deficiency exists. However, green colour may be improved by increasing light distribution early during fruit development. Bi-coloured pears attain their maximum red colour midway through their development, and this desired red colour is mostly lost prior to harvest. Red colour can also increase transiently with the passing of cold fronts. Anthocyanins, responsible for this red colour, may have a photoprotective function which would explain this pigmentation pattern, as photosystems are particularly sensitive to light damage at low temperatures. As ‘Rosemarie’ fruit bent over from a vertical to hanging position during development, peel photoinhibition was reduced as anthocyanins were synthesised. ‘Forelle’ peel was found to be very sensitive to high light levels at low temperatures. Substantial anthocyanin development took place in ‘Cripps’ Pink’ apples when weather conditions were cold, but clear following a cold front. A photoprotective role seems to explain daily changes in anthocyanins in response to temperature, but not the seasonal progression of colour development. For many apple (Malus domestica Borkh.) and pear (Pyrus communis L.) cultivars, attractive colour is essential to their profitability on export markets. This study focuses on problems related to poor green colour of ‘Granny Smith’ apples and insufficient red colour of bi-coloured pear cultivars. ‘Granny Smith’ apples often suffer from poor green colour.

A photoprotective role seems to explain daily changes in anthocyanins in response to temperature, but not the seasonal progression of colour development. Dwarfing rootstocks are known to improve red colour of bi-coloured pears due to improved light distribution. ‘Forelle’ fruit from six rootstocks of varying vigour were harvested from exposed positions only, so as to establish the effect of rootstock on red colour development independent of the effect of rootstock on canopy light distribution. Fruit from trees on quince (Cydonia oblonga Mill.) rootstocks were found to have redder fruit than those from vigorous BP pear rootstocks. This may be due to higher chlorophyll and carotenoid concentrations present in the peel of fruit from BP rootstocks, whose leaf and peel N were also high. The use of quince rootstocks is recommended where red colour development of bi-coloured pears is a problem. An early season bi-coloured cultivar with good red colour is required. Breeding trials to find such a cultivar are resource intensive. To streamline the process, a method to preselect immature seedlings for their future fruit colour is required. Fruit colour from bearing seedlings was compared with colour of their immature leaves. Trees with red leaves were likely to produce fruit that were too red for the breeders’ requirements. Trees with green or blushed leaves were capable of producing blushed fruit. It would be feasible to cull red-leaved seedlings with minimal risk of losing potential bi-coloured cultivars.<br>AFRIKAANSE OPSOMMING: Verskeie appel (Malus domestica Borkh.) en peer (Pyrus communis L.) kultivars se winsgewendheid word bepaal deur hul aantreklike kleur. In hierdie studie word die swak groen kleur van ‘Granny Smith’ appels asook rooi kleurontwikkeling van blospere ondersoek. Die groen kleur van ‘Granny Smith’ appels is dikwels onvoldoende. Verskille in groen kleur tussen boorde was reeds gedurende vroeë vrugontwikkeling aanwesig, en hierdie verskille het voortgeduur tot met oes. Groen kleur kon nie deur verskillende bronne en tye van stikstofbemesting verbeter word nie. Stikstofbemesting verbeter groen kleur moontlik net in boorde met ‘n stikstoftekort. Vrugte wat gedurende hul vroeë ontwikkeling oorskadu is, se groen kleur was swakker by oes in vergelyking met vrugte wat nie oorskadu is nie. Groen kleur kan moontlik verbeter word deur ligverspreiding tydens vroeë vrugontwikkeling deur middel van snoei aksies te verhoog. Blospeerkultivars bereik hul maksimum rooi kleur halfpad deur hul ontwikkeling, maar is geneig om hul rooi kleur grootliks voor oes te verloor. Rooi kleur mag egter kortstondig toeneem in reaksie op die lae temperature gepaardgaande met koue fronte. Antosianiene, wat verantwoordelik is vir die rooi kleur, het moontlik ‘n beskermende funksie teen hoë ligvlakke, en hierdie funksie mag moontlik die bogenoemde patroon van rooikleurontwikkeling verklaar. Die natuurlike buiging van ‘Rosemarie’ pere van hul aanvanklike regop oriëntasie tot hul karakteristieke hangende posisie, is gekenmerk deur ‘n afname in fotoinhibisie van die skil en ‘n gelyklopende sintese van antosianien. ‘Forelle’ skil was uiters sensitief vir hoë ligvlakke in kombinasie met lae temperature (16 ºC). ‘Cripps’ Pink’ appels het ‘n vinnig toename in rooi kleur getoon met die koue, maar helder, weerstoestande wat gevolg het op ‘n kouefront. Dit is welbekend dat dwergende onderstamme die rooi kleur van blospere verbeter deur ligverspreiding in die boom te verhoog. Ten einde die effek van onderstam op rooi kleurontwikkeling onafhanklik van die effek van onderstam op ligverspreiding te ondersoek, is ‘Forelle’ pere wat blootgestel was aan vol son geoes van bome geënt op ses onderstamme met verskillende groeikrag. Kweperonderstamme (Cydonia oblonga Mill.) het rooi kleur verbeter in vergelyking met die groeikragtige BP peeronderstamme. ‘n Moontlike rede vir die verbetering is die laer chlorofiel- en karotenoïedkonsentrasies in die skil van vrugte op kweperonderstamme. Bome op peeronderstamme het ook hoër blaaren skil stikstofvlakke gehad. Kweperonderstamme word aanbeveel in gevalle waar rooi kleurontwikkeling van blospere ‘n probleem mag wees. Die RSA vrugtebedryf benodig ‘n vroeë blospeerkultivar met goeie rooi kleurontwikkeling. Die teling van so ‘n kultivar is hulpbronintensief en baie duur. Ten einde die teelproses meer effektief te maak, word ‘n metode benodig om saailinge al voor uitplanting in die boord te selekteer na gelang van hul toekomstige vrugkleur. Die vrugkleur van oesryp pere van draende saailinge is vergelyk met die kleur van hul onvolwasse blare. Bome met rooi blare is geneig om vrugte te dra wat té rooi is om te kwalifiseer as blospere. Die meerderheid blospere is afkomstig van bome met blos of groen onvolwasse blare. Dit is prakties haalbaar om rooiblaarsaailinge uit te dun, met net ‘n klein, aanvaarbare risiko om ‘n moontlike blospeerkultivar in die proses te verloor.<br>medg2010-1<br>Imported from http://etd.sun.ac.za April 2010.

Abstract:
The Original Objectives were modified and two were eliminated to reflect the experimental results: Objective 1 - Identify additional genetic variability in SlGLK2 and IPin wild, traditional and heirloom tomato varieties Objective 2 - Determine carbon balance and horticultural characteristics of isogenic lines expressing functional and non-functional alleles of GLKsand IP Background: The goal of the research was to understand the unique aspects of chloroplasts and photosynthesis in green fruit and the consequences of increasing the chloroplast capacity of green fruit for ripe fruit sugars, yield, flavor and nutrient qualities. By focusing on the regulation of chloroplast formation and development solely in fruit, our integrated knowledge of photosynthetic structures/organs could be broadened and the results of the work could impact the design of manipulations to optimize quality outputs for the agricultural fruit with enhanced sugars, nutrients and flavors. The project was based on the hypothesis that photosynthetic and non-photosynthetic plastid metabolism in green tomato fruit is controlled at a basal level by light for minimal energy requirements but fruit-specific genes regulate further development of robust chloroplasts in this organ. Our BARD project goals were to characterize and quantitate the photosynthesis and chloroplast derived products impacted by expression of a tomato Golden 2- like 2 transcription factor (US activities) in a diverse set of 31 heirloom tomato lines and examine the role of another potential regulator, the product of the Intense Pigment gene (IP activities). Using tomato Golden 2-like 2 and Intense Pigment, which was an undefined locus that leads to enhanced chloroplast development in green fruit, we sought to determine the benefits and costs of extensive chloroplast development in fruit prior to ripening. Major conclusions, solutions, achievements: Single nucleotide polymorphisms in the promoter, coding and intronicSlGLK2 sequences of 20 heirloom tomato lines were identified and three SlGLK2 promoter lineages were identified; two lineages also had striped fruit variants. Lines with striped fruit but no shoulders were not identified. Green fruit chlorophyll and ripe fruit soluble sugar levels were measured in 31 heirloom varieties and fruit size correlates with ripe fruit sugars but dark shoulders does not. A combination of fine mapping, recombinant generation, RNAseq expression and SNP calling all indicated that the proposed localization of a single locus IP on chr 10 was incorrect. Rather, the IP line harbored 11 separate introgressions from the S. chmielewskiparent, scattered throughout the genome. These introgressions harbored ~3% of the wild species genome and no recombinant consistently recovered the IP parental phenotype. The 11 introgressions were dissected into small combinations in segregating recombinant populations. Based on these analyses two QTL for Brix content were identified, accounting for the effect of increased Brix in the IP line. Scientific and agricultural implications: SlGLK2 sequence variation in heirloom tomato varieties has been identified and can be used to breed for differences in SlGLK2 expression and possibly in the green striped fruit phenotype. Two QTL for Brix content have been identified in the S. chmielewskiparental line and these can be used for increasing soluble solids contents in breeding programs.

Full text
Abstract:
Fruit thinning is a common and necessary practice for commercial fruit production in many deciduous tree fruit species. Fruit thinning in apple may be accomplished with a variety of chemical thinning agents, but the use of these chemicals is a subject of environmental concern. It has been shown recently that RNase enzyme, secreted from the stigma and the style, inhibits pollen germination and pollen tube elongation. In this study we have been able to show that Aspergillus niger B-1 RNase can effectively inhibit peach and apple pollen germination, and tube elongation in-vitro, as well as thin fruit in peach and apple, and reduce the number of seeds in citrus. The objectives of the research were to detrmine the conditions for effective thinning of (USA and Israel), develop fermentation process for cost effective production of RNase from A. niger. (Israel), and clone apple S-RNase cDNA (USA). All the objectives of the research were addressed. We have determined the optimal fermentation conditions for cost effective production of the A. niger at a 20,000 liters scale. TheA. niger B1 RNase was isolated to homogeneity and its kinetic and biochemical properties including its N-terminal sequence were fully characterized. The field test results both in Israel and California have shown variability in effectiveness and more work is needed to define the RNase concentration necessary to completely inhibit pollen development. Plant transformation vectors expressing anti-sense apple S-RNase genes were constructed (USA) with an attempt to produce self compatible transgenic apple trees. Bovine S-Protein cDNA was cloned and successfully expressed in E. coli (Israel). Plant transformation vector expressing the S-Protein gene was constructed (USA) with an attempt to produce transgenic plants expressing S-protein in the style. Exogenous application of S-peptide to these plants will result in active RNase and consequently prevention of fertilization.

Full text
Abstract:
The cucurbit family, including melon, translocates the galactosyl-sucrose oligosaccharides, raffinose and stachyose, in addition to sucrose, from the source leaves to the fruit sink. The metabolism of these photoassimilates in the fruit sink controls fruit growth and development, including the horticulturally important phenomenon of sucrose accumulation, which determines melon fruit sweetness. During this research project we have characterized the complete pathway of galactosyl sucrose metabolism in developing fruit, from before anthesis until maturity. We have also compared the metabolic pathway in scurose accumulating genotypes, as compared to non-accumulating genotypes. Furthermore, we studied the pathway in different fruit tissues, in response to pollination, and also analyzed the response of the individual steps of the pathway to perturbations such as low temperature and leaf removal. The results of our studies have led to the conclusion that generally galactosyl-sucrose metabolism functions as a coordinately controlled pathway. In one case, as an immediate response to the absence of pollination, the activity of a single enzyme, UDPglu pyrophosphorylase, was drastically reduced. However, during young fruit development, sucrose accumulation, and in response to perturbations of the system, groups of enzymes, rather than single enzymes, respond in a concerted manner. Our research has characterized in detail the initial enzymes of galactosyl-sucrose metabolism, including the galactosidases, galactokinase and the UDPgal- and UDPglu pyrophosphorylases. We have discovered a novel alkaline a-galactoside which hydrolyzes both stachyose and reaffinose and thereby may have solved the dilemma of cytosolic-sucrose metabolism, since prior to this research there was no known alkaline a-galactosidase capable of hydrolyzing raffinose.

Full text
Abstract:
Bacterial fruit blotch (BFB) of cucurbits is caused by the Gram-negative bacterium Acidovorax citrulli. BFB affects cucurbit production worldwide, and mainly watermelon and melon. Most A. citrulli strains are divided into two genetically differentiated groups: while group I strains have been mainly associated with melon and other non-watermelon cucurbits, group II strains are more aggressive on watermelon. Like many Gram-negative plant-pathogenic bacteria, A. citrulli relies on a functional type III secretion system (T3SS) for pathogenicity. The T3SS is responsible for direct secretion of bacterial protein effectors to the host cell. Type III-secreted effectors (T3Es) contribute to virulence through manipulation of the host cell metabolism and suppression of plant defense. Our previous collaboration showed that group I and II strains significantly differ in their T3E arsenal (Eckshtain-Levi et al., Phytopathology 2014, 104:1152-1162). Using comparative genomics, we also showed that group I and II strains of A. citrulli have substantial differences in their genome content (Eckshtain-Levi et al., Front. Microbiol. 2016, 7:430). Our long-term goals are to identify the genetic determinants that contribute to virulence and host preferential association of the two major groups of A. citrulli, and to exploit these insights to develop effective BFB management strategies. We hypothesize that differences in the arsenal of T3Es, are greatly responsible for the differences in host preferential association between strains belonging to the two groups. The specific objectives of this project were: (1) to investigate the susceptibility of cucurbit species to group I and II strains under field conditions; (2) to assess the contribution of T3Es and other virulence factors to A. citrulli virulence and host preference; and (3) to characterize the mechanisms of action of selected T3Es of A. citrulli. In the frame of objective 1, we carried out three field experiments involving inoculation of several cucurbit crops (watermelon, melon, pumpkin and squash) with group I and II strains. Findings from these experiments confirmed that A. citrulli strains exhibit a preference for watermelon and melon. Moreover, we demonstrated, for the first time under field conditions, host-preferential association of group I and II strains to melon and watermelon, respectively. While host-preferential association was observed in leaves and in fruit tissues, it was more pronounced in the latter. In this part of the project we also developed a duplex PCR assay to differentiate between group I and II strains. In the frame of objective 2, we employed a multifaceted approach combining bioinformatics and experimental methods to elucidate the T3E arsenal of A. citrulli. These experiments led to discovery that A. citrulli strains possess large arsenals with more than 60 T3E genes. Remarkably, we found that ~15% of the T3E genes are group-specific. Advances were achieved on the contribution of selected T3E genes and other virulence determinants to the ability of A. citrulli to colonize the fruit and other tissues of melon and watermelon. Last, in the frame of objective 3, we advanced our understanding on the mode of action of few key T3Es of A. citrulli. We also optimized a virus-induced gene silencing (VIGS) system for functional genomics in melon and watermelon. This system will allow us to test melon and watermelon genes that may have defense or susceptibility roles related to BFB disease. Overall, this collaboration substantially enriched our knowledge on basic aspects of BFB disease. We believe that the fruits of this collaboration will greatly contribute to our ultimate goal, which is generation of durable resistance of melon and watermelon to A. citrulli.

Abstract:
Pepper exhibits large natural variation in chlorophyll content in the immature fruit. To dissect the genetic and molecular basis of this variation, we conducted QTL mapping for chlorophyll content in a cross between light and dark green-fruited parents, PI 152225 and 1154. Two major QTLs, pc1 and pc10, that control chlorophyll content by modulation of chloroplast compartment size in a fruit-specific manner were detected in chromosomes 1 and 10, respectively. The pepper homolog of GOLDEN2- LIKE transcription factor (CaGLK2) was found as underlying pc10, similar to its effect on tomato fruit chloroplast development. A candidate gene for pc1was found as controlling chlorophyll content in pepper by the modulation of chloroplast size and number. Fine mapping of pc1 aided by bulked DNA and RNA-seq analyses enabled the identification of a zinc finger transcription factor LOL1 (LSD-One-Like 1) as a candidate gene underlying pc1. LOL1 is a positive regulator of oxidative stress- induced cell death in Arabidopsis. However, over expression of the rice ortholog resulted in an increase of chlorophyll content. Interestingly, CaAPRR2 that is linked to the QTL and was found to affect immature pepper fruit color in a previous study, did not have a significant effect on chlorophyll content in the present study. Verification of the candidate's function was done by generating CRISPR/Cas9 knockout mutants of the orthologues tomato gene, while its knockout experiment in pepper by genome editing is under progress. Phenotypic similarity as a consequence of disrupting the transcription factor in both pepper and tomato indicated its functional conservation in controlling chlorophyll content in the Solanaceae. A limited sequence diversity study indicated that null mutations in CaLOL1 and its putative interactorCaMIP1 are present in C. chinensebut not in C. annuum. Combinations of mutations in CaLOL1, CaMIP1, CaGLK2 and CaAPRR2 are required for the creation of the extreme variation in chlorophyll content in Capsicum.
