Abstract:
Kekeringan merupakan salah satu masalah serius yang sering muncul ketika musim kemarau tiba dan berkepanjangan. Dari aspek hidrometeorologi kekeringan timbul dan disebabkan oleh berkurangnya curah hujan selama periode tertentu. Tujuan dari penelitian ini adalah untuk mengetahui jenis pohon dengan transpirasi paling besar berdasarkan karakteristik daun dan hasil total transpirasi. Hasil penelitian ini menunjukkan pohon gymnospermae yang daun paling lebar yaitu daun pohon melinjo 1 yaitu lebar 5,3 cm dan jenis pohon angiospermae yang daunnya paling lebar yaitu daun pohon ketapang 2 yaitu lebar 18,4 cm. Jenis pohon gymnospermae yang daun paling tebal yaitu daun pohon cemara norflok 1 dengan tebal daunya yaitu 0,049 mm, sedangkan jenis angiospermae pohon dengan daun paling tebal yaitu daun pohon ketapang 3 dengan tebal daunnya itu 0,015 mm. Jumlah total daun paling banyak yaitu jenis glodokan sebesar 7809. Pada jenis pohon gymnospermae rata-rata jumlah uap air yang dihasilkan paling banyak adalah pohon Melinjo dengan jumlah rata-rata 1.428,07 ml. Sedangkan pada jenis pohon angiospermae, pohon yang paling besar menghasilkan uap air yaitu Ketapang dengan nilai rata-rata 9.607,6 ml. Dari hasil pengamatan, peneliti menyimpulkan jenis pohon angiospermae yang paling banyak menghasilkan uap air yaitu jenis pohon Ketapang, karena dilihat dari panjang daun, lebar daun dan tipisnya daun sehingga pohon ketapang yang paling banyak menghasilkan uap air.

Abstract:
Cytokinins (CKs) control many plant developmental processes and responses to environmental cues. Although the CK signaling is well understood, we are only beginning to decipher its evolution. Here, we investigated the CK perception apparatus in early-divergent plant species such as bryophyte Physcomitrium patens, lycophyte Selaginella moellendorffii, and gymnosperm Picea abies. Of the eight CHASE-domain containing histidine kinases (CHKs) examined, two CHKs, PpCHK3 and PpCHK4, did not bind CKs. All other CHK receptors showed high-affinity CK binding (KD of nM range), with a strong preference for isopentenyladenine over other CK nucleobases in the moss and for trans-zeatin over cis-zeatin in the gymnosperm. The pH dependences of CK binding for these six CHKs showed a wide range, which may indicate different subcellular localization of these receptors at either the plasma- or endoplasmic reticulum membrane. Thus, the properties of the whole CK perception apparatuses in early-divergent lineages were demonstrated. Data show that during land plant evolution there was a diversification of the ligand specificity of various CHKs, in particular, the rise in preference for trans-zeatin over cis-zeatin, which indicates a steadily increasing specialization of receptors to various CKs. Finally, this distinct preference of individual receptors to different CK versions culminated in vascular plants, especially angiosperms.

Abstract Comparative phytochemical investigations were carried out on sporopollenins of the follow­ ing plant species: Bryophyta -Reboulia hemisphaerica and Polytrichum strictum; Pteridophyta -Equisetum arvense, Selaginella selaginoides micro-and megaspores; Gymnospermae -Cycas circinalis; Angiospermae -Typha angustifolia and Tulipa cv. “Apeldoorn”. Although the range of the analyses included species from the Bryophyta to the Angiospermae, fundamen tal correspondences could be detected in the 13C NMR and FTIR spectra concerning the occur­rence of aliphatics, aromatics, ether and carbonyl/carboxylic functions in varying degrees. While the amount of aliphatics strongly dominated in the molecular structure of all other sporopollenins investigated here, it was found in sporopollenin of Equisetum arvense in a much lower extent. Despite the different morphology of Selaginella selaginoides micro-and mega­ spores, their sporopollenin spectra were nearly identical

As plantas aquáticas são importantes componentes dos ecossistemas lóticos e lênticos. Como conseqüências de transformações ambientais, algumas podem se tornar dominantes, sendo que as plantas aquáticas do gênero Typha são bem sucedidas em brejos e alagados, podendo também ser encontradas em córregos e ribeirões. O presente estudo foi realizado com o objetivo de avaliar a influência de T. angustifolia para a ictiofauna em riachos. Foram estudados seis riachos na bacia do Alto Rio Turvo, Estado de São Paulo, desprovidos de vegetação ripária nativa, mas com abundância de T. angustifolia no hábitat interno e ripário. Por meio da análise de mapas de cobertura do solo, observou-se que T. angustifolia está amplamente distribuída nas zonas ripárias ao longo das drenagens estudadas. Os riachos com as maiores proporções de T. angustifolia nas zonas ripárias também apresentaram a menor riqueza de espécies e abundância de peixes. A baixa semelhança na composição e estrutura da ictiofauna entre os períodos sazonais, a grande quantidade de espécies tolerantes e o fato de que a maioria das espécies foi ou acessória ou acidental, sugerem uma dinâmica populacional do tipo “fonte e dreno” nos riachos estudados. Desta forma, os trechos livres de Typha atuam como “fontes”, provendo indivíduos que, por migração, podem ocasionalmente explorar os trechos com elevada abundância de T. angustifolia. Nestes trechos, que teriam o papel funcional de “drenos”, as condições ambientais são pouco apropriadas para a manutenção de uma comunidade diversa e residente de peixes. Os indivíduos dos trechos “fonte” à montante e à jusante que para ali migram se beneficiam de uma oferta relativamente constante de alimento, embora pouco variada (principalmente larvas aquáticas de Chironomidae e detritos), e abrigos (raízes de Typha).
Aquatic plants are a major component of lenthic and lotic ecosystems.

This study was made with the aim to investigate the influences of T. angustifolia on the fish assemblages in streams. A total of six streams in the Upper Rio Turvo basin, São Paulo state, without riparian vegetation but with abundance of T. angustifolia in the instream and riparian habitat, were studied. By analyzing soil coverage maps, it was registered that T. angustifolia was widespread in the riparian zones along studied drainages. Streams with the largest proportions of T. angustifolia along riparian zones were also those with lowest fish species richness and abundance. Low similarity in the composition and structure of fish fauna between seasonal periods, together with a large number of tolerant species, and the fact that most species are accessory or accidental, suggest a “source and sink” population dynamic in the studied streams. Thus, free Typha stretches play as a “source” habitat, providing individuals that, by migration, may occasionally explore stretches with large abundance of T. angustifolia. In these stretches, which play a “sink” functional role, environmental conditions are often little appropriated to the maintenance of a diverse and resident fish assemblage. The migrating individuals from up and down “source” stretches are benefited by relatively constant food offer, but few diverse (mostly aquatic larvae of Chironomidae and detritus), and shelters (Typha roots).

Abstract:
Deep phylogenetic relationships in the angiosperms had long been uncertain. However, by the end of the 1990s, large-scale studies contributed to the current well resolved picture of the tree of flowering plants, in which eudicots, monocots, and magnoliids are the three largest clades. Whereas monocots and eudicots have been recognized since the very first phylogenetic analyses, the monophyly of magnoliids (Canellales, Laurales, Magnoliales, and Piperales) is a more recent result. Magnoliidae, as now circumscribed, consist of 20 families and ca. 10,000 species mostly distributed in the tropics. Before the present thesis, several parts of the magnoliid tree had been well studied, but little was known about the evolutionary history of Magnoliidae as a whole. The first chapter of this thesis is a phylogenetic study conducted to clarify the relationships among families and orders of Magnoliidae. To do so, I sampled 199 species of Magnoliidae and 12 molecular markers from the three genomes and conducted phylogenetic analyses using parsimony, maximum likelihood, and Bayesian methods. The results confirm, with a greater level of support, two clades in Magnoliidae: Canellale + Piperales, and Laurales + Magnoliales. In addition, the relationships among the 20 families are generally well supported, and Lactoridaceae and Hydnoraceae are nested within Aristolochiaceae (Piperales). In the second chapter, the ages and phylogenetic positions of 10 fossils attributed to Magnoliidae were reviewed in detail. The goal of this study was to provide new reliable calibration points in order to conduct molecular dating analyses. These fossils were selected from the rich fossil record of the group because of their previous inclusion in phylogenetic analyses with extant taxa. The resulting calibration scheme provides six solid, internal minimum age constraints. The third chapter includes molecular dating analyses using the present calibration scheme and the same molecular dataset of Chapter 1. This study tends to push back in time the ages of the crown nodes of Magnoliidae (127.1-198.9 Ma), and of the four orders, Canellales (126.3-141.0 Ma), Piperales (88.2-157.7 Ma), Laurales (111.8-165.6 Ma), and Magnoliales (115.0-164.2 Ma). In the same chapter, I investigated the mode of diversification in the group. The strongly imbalanced distribution of species appears to be best explained by models of diversification with 6 to 14 diversification rate shifts. Finally, in the last chapter, I traced the evolution of 26 floral characters to reconstruct the ancestral flowers in key nodes of Magnoliidae. I used the phylogeny of Chapter 1 and an exemplar approach. Our results show that the most recent common ancestor of all Magnoliidae was a tree bearing actinomorphic, bisexual flowers with a differentiated perianth of two alternate, trimerous whorls of free perianth parts (outer and inner tepals) and probably three free stamens. This work provides key results on the evolution of Magnoliidae and raises several new questions such as the impact of geological crises on diversification of the group or the influence of pollinators and the environment on the evolution of floral morphology.

Abstract:
Angiosperms are one of the most dominant groups on Earth, and have fundamentally changed global ecosystem patterns and function. Therefore, unravelling their evolutionary history is key to understanding how the world around us was formed, and how it might change in the future. In this thesis, I use genome-scale data to investigate the evolutionary patterns and timescale of angiosperms at multiple taxonomic levels, ranging from angiosperm-wide to genus-level data sets. I begin by using the largest combination of taxon and gene sampling thus far to provide a novel estimate for the timing of angiosperm origin in the Triassic period. Through a range of sensitivity analyses, I demonstrate that this estimate is robust to many important components of Bayesian molecular dating. I then explore tactics for phylogenomic dating using multiple molecular clocks. I evaluate methods for estimating the number and assignment of molecular clock models, and strategies for partitioning molecular clock models in analyses of multigene data sets. I also demonstrate the importance of critically evaluating the precision in age estimates from molecular dating analyses. Finally, I assess the utility of plastid data sets for resolving challenging phylogenetic relationships, focusing on Pimelea Banks & Sol. ex Gaertn. Through analysis of a multigene data set, sampled from many taxa, I provide an improved phylogeny for Pimelea and its close relatives. I then generate a plastome-scale data set for a representative sample of species to further refine the Pimelea phylogeny, and characterise discordant phylogenetic signals within their chloroplast genomes. The work in this thesis demonstrates the power of genome- scale data to address challenging phylogenetic questions, and the importance of critical evaluation of both methods and results. Future progress in our understanding of angiosperm evolution will depend on broader and denser taxon sampling, and the development of improved phylogenetic methods.

Abstract:
L’effet du phoséthy-Al et du métalaxyl a été étudié sur le couple Lycopersicum esculentum Phytophthora capsici, ainsi que celui de l'acide phosphoreux, métabolite actif du phoséthyl-Al sur le même parasite in vitro. L'acide phosphoreux incorporé dans le milieu de culture, à une concentration de 200 µg ml-1, permet de constater en microscopie électronique que, l'organisme fongique ne présente pas un aspect proche de la léthalité. La paroi et le plasmalemme sont affectés et particulièrement les mitochondries. Ce phénomène est également retrouvé, et de façon régulière lorsque le parasite est observé à l'intérieur des feuilles de Tomate traitées au phoséthyl-Al à une concentration de 500 µg ml-1. L'action du métalaxyl sur le P. Capsici à une concentration de 50 µg ml-1, in vivo, est plus accentuée par rapport à celle du phoséthyl-Al, car il entraîne la destruction des mitochondries et altère considérablement la structure du plasmalemme. En comparant l'action du phoséthyl-Al et du métalaxyl in vivo, on constate que ce dernier agit à des doses plus faibles en détruisant le parasite très tôt. Les deux substances permettent d’augmente la résistance des cellules hôtes par la mise en place de corps X, dont la nature est polyphénolique

Electron microscopie observations showed some slight modification of the cell-wall, plasmalemma and mitochondria of the fungus when cultivated on 200 mg ml-1 phosphorous acid. Similar modification were observed on infected tomato leaf-lets treated with 500 mg ml-1 fosetyl-Al. The in vivo effect of metalaxyl (500 mg ml-1) on P. Capsici is more acute than the fosetyl-Al one.

Animais visitam flores em busca de recursos, no entanto, ao transportar grãos de pólen entre os indivíduos da mesma espécie vegetal, atuam como mediadores no processo de seleção sexual, importante força na evolução florai. Fatores ecológicos que afetam a relação entre plantas e polínizadores podem influenciar a evolução das estratégias reprodutivas das espécies. Fatores abióticos, a distribuição espacial, o tamanho populacional e a história de vida das plantas podem modificar a abundância e a distribuição dos recursos para os polínizadores, alterando padrões de transporte de pólen, fluxo gênico e pressões seletivas responsáveis pela evolução floral. Este trabalho busca compreender a diversidade das estratégias reprodutivas em diferentes formações vegetais tropicais, a modulação por características vegetativas e reprodutivas das plantas e abióticas do meio na alocação de recursos como, também, verificar a existência de consistência biogeográfica dos padrões alométricos em relação as estratégias reprodutivas das plantas. O estudo foi realizado em áreas de vegetação tropical, sendo uma área de Floresta Atlântica, uma área de Cerrado, ambas no estado de São Paulo e uma área de Campo Rupestre, no estado de Minas Gerais, permitindo a comparação da variação da biomassa floral entre as três formações vegetais e entre angiospermas tropicais com particularidades morfológicas relacionadas às áreas de coleta e dados bibliográficos de espécies extra-tropicais. A riqueza de formas vegetais e de ambientes nas regiões tropicais atua na modulação da interação entre plantas e polínizadores, influenciando na variação da biomassa floral e nas características vegetativas e reprodutivas das espécies. As alometrias positivas e a isometria encontradas nas floras tropicais e extra-tropícats em relação ao crescimento da biomassa floral apontam para a presença e desenvolvimento de características sexuais secundarias como importantes ferramentas na permanência e sucesso da reprodução cruzada. Características vegetativas e reprodutivas influenciam na variação interespecífica da biomassa floral e que a função masculina da flor teria forte impacto na evolução das características florais, independentemente da ligação filogenética entre as angiospermas, ressaltando a necessidade de teorias que permitam uma síntese destas relações.
Abstract: Plants are sessile organisms exposed to the effects of environmental stress. The flowers are fundamental structures in the evolution of angiosperms, because through them is sexual reproduction. For this, the flowers exhibit strategies that help the plant to achieve better reproductive success. Animals visit flowers in search of resources, however, to carry pollen between individuals of the same plant species, act as mediators in the process of sexual selection, major force in floral evolution. Ecological factors affecting the relationship between plants atid pollinators may influence the evolution of reproductive strategies of species. Abiotic factors, spatial distribution, population size and life history of plants can modify the abundance and distribution of resources for pollinators by changing patterns of pollen transfer, gene flow and selective pressures responsible for floral evolution. This work seeks to understand the diversity of reproductive strategies in different tropical vegetation types, the modulated vegetative and reproductive features of plants and the abiotic environment in resource allocation as well, check for consistency biogeographical of allometric patterns in reproductive strategies in relation to plants. The study was conducted in areas of tropical vegetation, with an area of Atlantic Rain Forest, an area of Savannah, both in the state of Sao Paulo and an area of Campo Rupestre, in the state of Minas Gerais, allowing the comparison of variation among floral biomass the three vegetation types and between tropical angiosperm morphological peculiarities related to the areas of collection and bibliographic data of extra-tropical species. The richness of plant forms and environments in tropical acts in modulating the interaction between plants and pollinators, influencing the variation of biomass in the floral and vegetative and reproductive characteristics of species. The positive allometry and isometry floras found in tropical and extra-tropical growth over the floral biomass indicate the presence and development of secondary sexual characteristics as important tools in the permanence and success of cross-breeding. Vegetative and reproductive characteristics influence the interspecific variation of floral biomass and that the function of male flowers have a strong impact on the evolution of floral traits, regardless of the phylogenetic connection between the angiosperms, highlighting the need for theories that allow a synthesis of these relationships.

Abstract:
Orobanche is an important parasitic weed. For developing novel methods for its control, a thorough understanding of crucial stages of its development is needed. Therefore, the objectives of this project were characterization of Orobanche germination stimulants, analysis of mechanisms of haustorial penetration, and characterization and isolation of penetration enzymes. The first highly potent natural germination stimulant for Orobanche was isolated from sunflower and identified by high-field 1D (1H and 13C), 2D (1H-1H COSY, HMQC, HMBC)-NMR, GC.FT-IR, and GC.MS as costuslactone, a guaiane type sesquiterpene lactone that resembles strigol only in possessing a lactone moiety that is required for activity. The first direct in situ evidence for the enzymatic nature of the infection process of a parasitic angiosperm was established. Pectin deesterification and depletion of pectins in host cell walls were shown adjacent to haustorial cells. Pectin methyl esterase and polygalacturonase were immunocytochemically detected in intrusive cells and in adjacent host apoplast. Orobanche tissues contain inhibitors of PGase activity. PME and three PGases were isolated from Orobanche calli. PME was characterized and purified, and antibodies were prepared against it. This study presents novel findings regarding parasitism in Orobanche, which may help to open up new approaches for controlling broomrapes.

Abstract:
Abstract Mitochondria are the site of respiration and numerous other metabolic processes required for plant growth and development. Increased demands for metabolic energy are observed during different stages in the plants life cycle, but are particularly ample during germination and reproductive organ development. These activities are dependent upon the tight regulation of the expression and accumulation of various organellar proteins. Plant mitochondria contain their own genomes (mtDNA), which encode for rRNAs, tRNAs and some mitochondrial proteins. Although all mitochondria have probably evolved from a common alpha-proteobacterial ancestor, notable genomic reorganizations have occurred in the mtDNAs of different eukaryotic lineages. Plant mtDNAs are notably larger and more variable in size (ranging from 70~11,000 kbp in size) than the mrDNAs in higher animals (16~19 kbp). Another unique feature of plant mitochondria includes the presence of both circular and linear DNA fragments, which undergo intra- and intermolecular recombination. DNA-seq data indicate that such recombination events result with diverged mitochondrial genome configurations, even within a single plant species. One common plant phenotype that emerges as a consequence of altered mtDNA configuration is cytoplasmic male sterility CMS (i.e. reduced production of functional pollen). The maternally-inherited male sterility phenotype is highly valuable agriculturally. CMS forces the production of F1 hybrids, particularly in predominantly self-pollinating crops, resulting in enhanced crop growth and productivity through heterosis (i.e. hybrid vigor or outbreeding enhancement). CMS lines have been implemented in some cereal and vegetables, but most crops still lack a CMS system. This work focuses on the analysis of the molecular basis of CMS. We also aim to induce nuclear or organellar induced male-sterility in plants, and to develop a novel approach for fertility restoration. Our work focuses on Brassicaceae, a large family of flowering plants that includes Arabidopsis thaliana, a key model organism in plant sciences, as well as many crops of major economic importance (e.g., broccoli, cauliflower, cabbage, and various seeds for oil production). In spite of the genomic rearrangements in the mtDNAs of plants, the number of genes and the coding sequences are conserved among different mtDNAs in angiosperms (i.e. ~60 genes encoding different tRNAs, rRNAs, ribosomal proteins and subunits of the respiratory system). Yet, in addition to the known genes, plant mtDNAs also harbor numerous ORFs, most of which are not conserved among species and are currently of unknown function. Remarkably, and relevant to our study, CMS in plants is primarily associated with the expression of novel chimericORFs, which likely derive from recombination events within the mtDNAs. Whereas the CMS loci are localized to the mtDNAs, the factors that restore fertility (Rfs) are identified as nuclear-encoded RNA-binding proteins. Interestingly, nearly all of the Rf’s are identified as pentatricopeptide repeat (PPR) proteins, a large family of modular RNA-binding proteins that mediate several aspects of gene expression primarily in plant organelles. In this project we proposed to develop a system to test the ability of mtORFs in plants, which are closely related to known CMS factors. We will induce male fertility in various species of Brassicaceae, and test whether a down-relation in the expression of the recombinantCMS-genes restores fertility, using synthetically designed PPR proteins.
