Abstract:
The studies were carried out with the aim of revealing histological reactions in the shoots of remontant raspberries as an aspect of the growth-stimulating effect of pre-planting treatment of the root system of seedlings with strains of saprotrophic bacteria of the genus Bacillus. The observations in the model experiment were carried out in 2017-2018 in the production plantings of remontant raspberries of the agricultural artel “Sady Sibiri” in the Novosibirsk Region. Plants were treated before planting by soaking the root system in a working fluid containing a bioagent at a concentration of 1×105 CFU / ml. In terms of the totality of growth-stimulating effects, the most effective complex effect on remontant raspberry plants was provided by pre-planting treatment with B subtilis strain VKPM B-10641 and a mixture preparation Fitop 8.67. The number of replacement shoots increased by 45–69%, the length of replacement shoots - by 16–20%, the amount internodes - 1.2 times relative to control. Under the influence of the same bacterial bioagents in the shoots of remontant raspberries, an increase in the thickness of the peridermis by 20–25% relative to the control, an increase in the number of peridermal layers by 12–35%, suberinized (matured) layers of the peridermis by 30–48%, and the thickness of xylem by 12 –22% was observed. B subtilis VKPM B-10641 strain and Fitop 8.67 influence raspberry plants, the regularity of simultaneous stimulation of growth processes in the replacement shoots and the formation of mature peridermis. So it acts as an immunological barrier against phytopathogens, pests and abiotic stress factors. So the research proved it.

<p>El objetivo de este trabajo es determinar si existe relación entre las características morfológicas de genotipos de <em>Solanum phureja </em>de la colección de trabajo de la Universidad Nacional de Colombia y la respuesta al ataque de la sarna polvosa en tubérculos. Se evaluaron 93 genotipos y de cada uno se cosecharon diez tubérculos en el municipio de La Unión (Ant). Se determinó la densidad y el área de las lenticelas, el grosor de la peridermis, el color y forma de los tubérculos. Los datos obtenidos se confrontaron con la información de la incidencia de la sarna polvosa en tubérculos, bajo condiciones de campo. Se encontró que existe una amplia variabilidad genética en la colección evaluada para todas las características morfológicas de tubérculos. Los tubérculos de color negro presentaron mayor densidad y área de lenticelas y el menor grosor de peridermis, mientras que los genotipos rojizos presentaron menores densidades y área de lenticelas y valores intermedios para el grosor de la peridermis. Por otro lado los tubérculos alargados presentan mayor densidad de lenticelas y menor grosor de peridermis, mientras que los tubérculos ovalados presentan el comportamiento contrario. Igualmente se encontró que los tubérculos redondos presentaron bajos valores de densidad de lenticelas y grosor de la peridermis. No se encontró relación entre las características morfológicas evaluadas y la incidencia de la sarna polvosa en campo.</p>

Abstract:
Antecedentes y Objetivos: Ceiba aesculifolia y C. pentandra (Malvaceae) son dos de las cuatro especies de Ceiba presentes en México. Se conocen como “pochotes”; sus cortezas tienen usos ornamentales y medicinales. Con la finalidad de encontrar atributos distintivos entre estas dos especies de amplia distribución en el país, se realizó un estudio comparativo de la estructura anatómica de la corteza a lo largo de sus ejes y su relación con posibles adaptaciones ecológicas. Métodos: Se recolectaron muestras desde las ramas nuevas hasta el tronco principal de cuatro individuos en un bosque tropical caducifolio de los estados de México y Puebla. Se realizaron cortes histológicos de la corteza con un microtomo de deslizamiento; las secciones se tiñeron con safranina-verde rápido y se montaron en resina sintética. Resultados clave: La corteza es ligeramente fisurada a fisurada en tallos maduros, de color gris plomizo en C. aesculifolia y verde en C. pentandra; con aguijones. La peridermis se origina de un estrato subepidérmico en los ápices de las ramas; conforme los ejes aumentan en diámetro, los radios se dilatan fuertemente (forma de embudo) y las fibras del floema se organizan en estratos, características compartidas con otras Bombacoideae (Malvaceae). Ceiba pentandra mantiene parches de peridermis que se alternan con epidermis, aguijones no estratificados y drusas escasas (<20/mm2), mientras que en C. aesculifolia hay ritidoma, aguijones estratificados y drusas abundantes (50-60/mm2). Conclusiones: Detalles de los cambios estructurales a lo largo del eje, además de las diferencias encontradas entre ambas especies se reportan por primera vez para Ceiba. La rápida diferenciación de la peridermis en las ceibas estudiadas, se interpreta como una adaptación para protección de la luz solar y la desecación; aspecto que ha sido observado en otras especies que crecen en ambientes estacionales.

Abstract:
Abstract Vascular plants with secondary growth develop a periderm mostly composed of dead suberized cork cells to face environmental hostile conditions. Cork oak has a highly active and long-living phellogen forming a remarkably thick periderm that is periodically debarked for industrial purposes. This wounding originates the quick formation of a new traumatic periderm, making cork oak an exceptional model to study the first periderm differentiation during normal development in young sprigs and traumatic (wound) periderm formation after debarking. Here, we studied the poorly known first periderm differentiation steps that involve cell wall suberization, polyphenolic accumulation and programmed cell death (PCD) by combining transmission electron microscopy, histochemical and molecular methods in periderms from young sprigs. These processes were further compared with traumatic periderms formed after wounding using molecular and histochemical techniques, such as the polyphenolic accumulation. In the first periderms from young sprigs, four distinct differentiation stages were defined according to the presence of PCD morphological features. First young and traumatic periderms showed an upregulation of genes related to suberin biosynthesis, proanthocyanidins biosynthesis and transport, autophagy, and PCD. Traumatic periderms revealed an overall upregulation of these genes, likely resulting from ontogeny differences and distinct phellogen origin associated with a faster metabolism, highlighting the impact of wounding on phellogen activity after debarking. First periderms from young sprigs showed gradual accumulation of proanthocyanidins in the vacuoles throughout PCD stages until total filled lumens, whereas in traumatic periderms, these compounds were found cell wall linked in already empty cells. This work enabled a comprehensive overview of the cork cells differentiation processes contributing to deepening the knowledge of the fundamental ontogenic program of this protective tissue, which is also a unique forest product, constituting the basis of a sustainable and profitable industry.

Abstract:
Rauvolfia sellowii Müll. Arg. (Apocynaceae), a Brazilian native tree rich in indole alkaloids, is known as "pau-pra-tudo" and popularly used as hypocholesterolemic, hypoglycemic and antihypertensive. The aim of this work was to study the anatomy of the young stems and stem barks of this medicinal plant, in order to contribute to the identification of the species as a drug. The plant material was fixed and prepared according to standard microtechniques. The young stems have remaining epidermis, but a suberified peridermis is evident. The phellogen is located in the cortical region, forming suber externally. Underneath the phellogen, lies the phelloderm and collenchymatic region. In the cortex, there are numerous laticifers and some fibers. There is an incomplete sclerenchymatic sheath, consisting of several groups of fibers and stone cells. The stem has internal phloem ordered as isolated groups side by side. Numerous laticifers, calcium oxalate crystals, idioblasts and amyloplasts are found in the cortex, phloem, xylem and pith. The stem bark has many layers of suber and cortical parenchyma, a sheath composed of fibers and stone cells totally lignified, and external phloem. These anatomical characteristic, taken together, can be used as quality control parameters for this species.

La madera de Libidibia paraguariensis (D. Parodi) G. P. Lewis “guayacán”, es homóloga a la de Diospyros ebenum J. Koenig “ébano”. Es una madera cuyas características tecnológicas y organolépticas le otorgan extraordinaria calidad y gran potencial futuro. Por este motivo los objetivos del trabajo fueron: (1) profundizar el conocimiento de las cualidades anatómicas del leño y la corteza;(2) analizar la relación albura-duramen y (3) caracterizar los anillos de crecimiento. El estudio se realizó empleando muestras provenientes de Guasayán, Santiago del Estero y Villa Rio Bermejito, Chaco (Argentina). Seis árboles de cada sitio, fueron seleccionados al azar. Se consiguió una rodaja del fuste principal de cada individuo, a una altura de 1,3 m. Se realizó la descripción del leño y de la corteza. El carácter anatómico relevante con alto valor diagnóstico resultó la estratificación completa de los radios. Los anillos son demarcados, con un incremento radial (IR) medio de 3,57 mm, el crecimiento es lento a medio, con albura gruesa. El leño presenta características correspondientes a una especie mesomórfica. La corteza externa con una o dos peridermis acumuladas, presenta dehiscencia en placas delgadas, lo cual resulta un elemento diagnóstico para la determinación a campo.

Abstract:
Phytophthora cinnamomi es uno de los fitopatógenos más devastadores a nivel mundial, ya que ocasiona pudriciones de raíz y la muerte de numerosas especies vegetales. El objetivo de este estudio fue determinar los daños histológicos inducidos por este organismo a nivel radicular en Pinus patula y Pinus pseudostrobus. Se inocularon 48 árboles de 11 meses de edad de ambas especies forestales mediante la inmersión de sus raíces en una suspensión de fragmentos miceliales y como testigo, otras que fueron sumergidas en agua destilada estéril. Se tomaron muestras de tales estructuras cada cuatro días después de la inoculación por 20 días. Los síntomas microscópicos se manifestaron con mayor rapidez en P. pseudostrobus, aunque en las dos especies las raíces se tornaron frágiles y se necrosaron. Asimismo, los cambios histológicos se presentaron como un aumento en el contenido de polifenoles, degradación de las paredes celulares y necrosamiento de la peridermis. En P. patula, las plantas mostraron un marchitamiento de la copa, seguida por un amarillamiento de las acículas y, finalmente, en la muerte del árbol. Para P. pseudostrobus los síntomas fueron similares, pero el decaimiento de las acículas fue gradual y, posteriormente, se observó marchitez de las mismas hasta la muerte total del ejemplar.

Abstract:
To understand the pathway used by Phytophthora cinnamomi Rands to penetrate the bark of jarrah, the present study describes unwounded periderm and rhytidome development. Periderm formation is described from its initiation in 4-week-old seedlings to the formation of rhytidome in saplings. Periderm in young seedlings consists of a single type of phellem, namely thin-walled suberised cells. In older seedlings where multiple layers of periderm have formed, layers of thick-walled lignified phellem cells in compacted bands alternate with thin-walled suberised cells. Rhytidome formation in older lignotuberous seedlings and in sapling jarrah occurs through the isolation of secondary phloem by periderm. The rhytidome consists of expanded and partially disintegrated secondary phloem tissue sandwiched between layers of phellem cells. Localised periderm formation beneath stomata results in the formation of lenticels, which are ephemeral features. Superficial periderms occur at sites of leaf and shoot abscission, and of lateral shoot emergence. Concealed axillary shoots lack cuticle on emergence. As the trees age, the internal production of lignified and suberised periderm and rhytidome results in an impenetrable barrier to invasion by P. cinnamomi. However, external sites including lenticels and leaf and shoot abscission and emergence areas, all provide points of ingress in unwounded stems.

Abstract:
The origin and structure are described of the secondary protective tissue in the stem of Erythorxylum tortuosum Mart., a fire tolerant shrubby species common in Brazilian cerrado. The highly tortuous stems are covered with thick bark which is more developed at the base of the stem. After fire in the cerrado, rhytidome fragments of the burned stem flake off, revealing newly formed cork. The first periderm appears near of the terminal buds and is iniated by periclinal divisions in subepidermal cells giving rise to radial rows of cells. The first phellogen is discernible only after the differentiation of the several radial rows of cork cells. Other phellogens have their origin in successively deeper layers of the cortex. The sucessive periderms are discontinuous around the circumference. The collapsed cells with phenolic substances and the accumulated dead cells cause the formation of discontinuous blackish lines, which delimit the sucessive periderms in the rhytidome. The rhytidome contains large quantities of sclereids developed from cell wall thickening of cortex cells. The occurrence of periderm in the young parts of the stem and of rhytidome in the older parts represents pyrophytic characteristics and may explain, in part, the fire tolerance of this species.

Abstract:
We have developed new molecular tools to characterize the FHT and StRIK genes in the tuber periderm. Regarding FHT gene, our results demonstrated that is induced very specifically in suberizing tissues what makes FHT a good marker of the suberization process. Regarding StRIK gene, it has been shown to be a good candidate for the periderm regulation since its silencing causes changes in genes expression related to the transposition of DNA, RNA processing and stress. Finally, by RNA-seq we have identified a wide range of new candidate genes for the formation of the cork oak periderm. Among these genes several are related to the formation of the cell wall, cell primary metabolism and suberin accumulation. Other relevant genes are those involved in the regulation of meristem such as auxin transporters and the ethylene metabolism and signaling. The expression patterns of some genes have been studied during the cork growing season.
Hem desenvolupat noves eines moleculars per a la caracterització dels gens FHT i StRIK en el peridermis del tubercle. Els nostres resultats mostren que FHT s’indueix de forma molt específica en teixits suberificats el que el fa un bon marcador del procés de suberificació. En relació al gen StRIK, hem vist que es un bon candidat a la regulació de la peridermis ja que el seu silenciament provoca canvis d’expressió en gens relacionats amb la transposició de l’ADN, el processament de l’RNA i l’estrès. Mitjançant RNA-seq hem identificat nous gens candidats per la formació de la peridermis en l’alzina surera, entre ells destaquen gens relacionats amb la formació de la paret cel·lular, el metabolisme primari i l’acumulació de suberina. També destaquen gens relacionats amb la regulació del meristema com ara els transportadors d’auxines i el metabolisme i senyalització per etilè.

Abstract:
The results obtained in this thesis indicate that StNAC103 promoter activity is induced in tissues undergoing suberin synthesis. Moreover StNAC103 transcript accumulation is concomitant to that of CYP86A33 and takes place after that of FHT. Nonetheless, an increase of the suberin and wax accumulation in the silenced periderms for StNAC103 suggests its role as a repressor in suberin and wax accumulation. Altogether these studies support the hypothesis that there exists a very fine regulation of the suberin and wax synthesis in the periderm, in which StNAC103 plays an important role.
Els resultats obtinguts en aquesta tesi indiquen que l’activitat del promotor d’StNAC103 s’indueix en teixits on és activa la síntesi de suberina i l’acumulació del transcrit corresponent es dóna concomitantment a la de l'ω-hidroxilasa d’acids grassos CYP86A33 i s’inicia posteriorment a la de la feruloïl transferasa d’ω-hidroxiacids i alcohols FHT. Tanmateix, l’augment en l’acumulació de suberina i ceres en els peridermes silenciats per StNAC103 suggereix un paper repressor d’aquest factor de transcripció. Tot plegat fa pensar que hi ha d’haver una regulació molt fina de la síntesi de suberina i ceres en el periderma i que StNAC103 hi té un paper destacat.

Resumo: Avaliar a estrutura anatômica de plantas que crescem em diferentes ambientes é uma maneira de compreender como as plantas se adaptam às variações destes ambientes. Algumas destas adaptações influenciam no transporte de água e de fotoassimilados, na proteção dos tecidos internos, na força mecânica e na capacidade de armazenamento dos tecidos, que são funções associadas ao caule das plantas. Assim, neste trabalho, avaliamos a estrutura caulinar de duas espécies, Moquiniastrum polymorphum e Zanthoxylum rhoifolium que ocorrem simultaneamente em diferentes tipos vegetacionais: o cerrado sensu stricto, o cerradão, a floresta estacional semidecídua e a floresta ombrófila densa. Os três primeiros tipos vegetacionais têm um período de seca durante o ano, enquanto que na floresta ombrófila densa o regime pluviométrico é relativamente constante ao longo do ano. Os solos de cada local apresentam diferentes propriedades físicas e químicas e no cerrado sensu stricto o fogo é um fator ambiental que pode ocorrer naturalmente. Estes fatores podem influenciar a estrutura anatômica dos tecidos vegetais. Para a descrição anatômica coletamos amostras do caule (a 1,30 m do solo) contendo xilema secundário e casca, pelo método não destrutivo, de cinco indivíduos de cada tipo vegetacional, que foram processadas conforme técnicas usuais em anatomia da madeira. Para verificar as diferenças entre os tipos vegetacionais, nós comparamos as características anatômicas por meio de uma análise de variância. ... (Resumo completo, clicar acesso eletrônico abaixo)

Abstract:
The periderm is a complex structure that protects plants’ secondary organs and wounded tissues. This function is given by the phellem, a multilayered tissue formed by cells with suberized cell walls located on the outer part of the periderm. Suberin is a basic polymer for protection thanks to its lipid nature. Exceptionally, the cork oak has a great capacity to produce layers of phellem. Recently, transcriptomics studies, as well as reverse genetic approaches, have contributed to the knowledge of the formation and regulation of the periderm and the synthesis and transport of the suberin components. However, the molecular bases that control these processes are still quite unknown. For this reason, new regulatory and transport candidate genes have been characterized. In addition, a faster and less expensive roots transformation system has been developed. Finally, a global transcriptome analysis of the outer bark of cork oak during its growth has been performed
El periderma és una estructura complexa que protegeix els òrgans secundaris i els teixits cicatricials.

A més, s'ha posat a punt un sistema de transformació d'arrels més ràpid i menys costós.

This work had three main goals: (1) to study the process of the phellogen and first periderm formation in young plants of cork-oak (Quercus suber); (2) to study the process of cork-tissue formation in adult cork-oak trees under cork exploitation, including the suberification process of cork cell walls and, (3) to study the structure of suberized cell walls in the periderm of potatoes, including a wild-type and three mutatans, where genes involved in suberin synthesis were supressed. To this end were used optical microscopy techniques, including bright field, epi-fluorescence and polarized light, together with scanning electron microscopy (SEM). The main results were: · the phellogen is formed in cork-oak before a month’s life of the young plants; · in the cork forming tissue three zones can be seen – the outer one, where cells are still dividing; – a middle one, were cork cell walls are thickening, and the inner one, contiguous to the mature cells, were cells still kept abundant cytoplasm material, although their cell walls already show their definitive thickness and, · the silencing of the genes involved in the ester-linking between the aliphatic and aromatic domains of suberin have the higher effect in the disrupting of suberized cell walls in potato periderm.

Abstract:
Potato (Solanum tuberosum L.) is the world's fourth largest food crop and large financial losses are incurred each year from wound and bruise related injuries. However, little is known about the coordinate induction of genes that may be associated with, or mark major wound-healing and periderm maturation events. Also, one of the key defense mechanisms for potato tubers is the robust barrier provided by the phellem (skin) of the native periderm. Many biological processes are involved in the formation of this stout tissue. However, little is known about induction of genes that may be associated with this process. The objectives of this research were to molecularly assess the processes of wound periderm development and maturation, and native periderm maturation in potato tubers. In this study, these processes were determined in coordination with expression profiles of selected genes. The cell cycle, cell wall protein, and pectin methyl esterase genes were determined from two diverse potato genotypes and two harvests NDTX4271-5R (ND) and Russet Burbank (RB) tubers; 2008 and 2009 harvests. Cell cycle genes encoding epidermal growth factor binding protein (StEBP), cyclin-dependent kinase B (StCDKB), and cyclin-dependent kinase regulatory subunit (StCKS1At) expression profiles were coordinated with related phellogen formation and the induction and cessation of phellem cell formation. Genes encoding the structural cell wall proteins extensin (StExt1) and extensin-like (StExtlk) expression profiles suggested involvement with closing layer formation and subsequent phellem cell layer formations. The coordinate induction and expression profile of StTLRP, a gene encoding a cell wall strengthening "tyrosine- and lysine-rich protein," suggested a role in the formation of the closing layer followed by phellem cell generation and lastly cell wall thickening in nonmeristematic phellogen cells. StPME and StPrePME expression increased during periderm development, implicating involvement in modifications for closing layer and phellem cell formation. Collectively, these results indicate that the genes monitored were involved in and their expression profiles markedly coordinated with periderm formation and the on-set of periderm maturation; results were more influenced by harvest than genotype. Importantly, StTLRP was the only gene examined that may be involved in phellogen cell wall strengthening or thickening after cessation of cell division.

Abstract:
Peridermium pini causes a stem rust of two-needled pine trees, with the greatest problems in the United Kingdom associated with Scots pine forests in north-east Scotland.  It was hypothesised that silvicultural practices are viable options for controlling the incidence of P. pini and that a combination of climatic and biophysical factors may be significant in regulating the incidence of the disease.  P. pini incidence was determined in four Scots pine plantations established in Moray, and in five native pinewoods.  P. pini incidence in the Scots pine forests of north-east Scotland has increased since the previous surveys undertaken in the 1960s.  Mean disease incidence for all plantations was 4.9%, with a range from 4.0% at Cawdor Estate to 5.7% at Darnaway Estate. Age-class, the number of years since thinning, elevation and continentality were statistically significant factors influencing disease incidence.  These factors were used as the basis for a rule-based model to describe the distribution of P. pini within the forests surveyed. A second modelling approach, using Bayesian methods to analyse a large number of datasets, supported the hypothesis that management factors had the major influence on incidence of the disease and that climatic factors added, incrementally, to explaining the spatial distribution of the disease.  Maps produced from the outputs designated the probabilities of P. pini incidence into risk classes. Estimation of timber volume losses in infected stands confirmed that the disease would have significant economic impact in most sites if no savage thinnings were undertaken.  This process would have the most significant effect at Altyre Estate. The combination of these modelling approaches with Geographic Information Systems is potentially useful as a decision-support tool for forest managers, enabling greater confidence in judging the potential local significance of the factors affecting disease incidence.
