Full textAngiosperms are a clade known for its great species diversity and the uneven distribution of this diversity among its lineages. This work focuses on the ancestral state reconstruction of floral characters on phylogenies in the purpose of studying their impact on diversification. We first focused on two potential key innovations in Proteaceae, bilateral perianth symmetry and presence in Mediterranean-climate hotspots. Using character state dependent diversification models, we found that the first character state did not have any significant impact on species diversification in this group, contrary to the second one. We then reconstructed ancestral states for perianth symmetry in angiosperms as a whole, using a sampling strategy aimed at capturing all of the transitions in this character. We found a minimum of 130 origins of bilateral symmetry, followed by 69 subsequent reversals to radial symmetry. Lastly, the same approach was extended to the study of four other perianth characters. Different ancestral state reconstruction models were used on a phylogenetic tree of 1232 species to test the influence of model changes on reconstructed ancestral states. Our results show that changes in reconstruction models have an impact on the inferred ancestral state of some nodes, but not all of them. The various results obtained for symmetry, a character shared among the three chapters, indicate that our sampling method has the drawback of estimating transition rates too high to give conclusive results with maximum likelihood. On the other hand, results are much less biased when several characters are examined simultaneously

Resumo:Além de fonte primária de carbono e energia para os principais tipos celulares, os açúcares produzidos pela fotossíntese adquiriram importantes funções ao longo da evolução das plantas, no controle do crescimento e desenvolvimento, do metabolismo e na resistência a estresses abióticos (osmótico, energético) e bióticos (potógenos). Os açúcares atuam como sinalizadores ativando cascatas de transdução e, desta forma, promovendo mudanças na programação da expressão gênica. Com o objetivo de entendermos como a sinalização por açúcares diversificou-se em angiospermas, iniciamos uma análise comparativa dos perfis de expressão gênica em resposta aos açúcares sacarose e glicose em plântulas da monocotiledônea Saccharum spp e da eudicotiledônea Arabidopsis thaliana. Para tanto, duas abordagens foram utilizadas. O primeiro aspecto do trabalho estabeleceu relações entre elementos de resposta rápida (resposta primária) a açúcar e acúmulo de sacarose em genótipos de cana contrastantes para teor de sacarose. Outra abordagem, mais abrangente, procurou identificar genes diferencialmente expressos em resposta à sacarose. Na primeira parte do trabalho, a análises por qRT-PCR revelaram uma clara relação entre genes envolvidos em acúmulo de sacarose em cana-de-açúcar e sinalização primária por carboidratos. A partir de 34 SAS (Sugarcane Assembled Sequence) testados envolvidos em acúmulo de sacarose em cana, 24 deles também foram responsivos à glicose e/ou sacarose, sendo que 9 deles responderam em um mesmo sentido em genótipos de cana-de-açúcar que acumulam maior quantidade de sacarose (alto Brix). Dos 24 SAS responsivos à sacarose e/ou glicose, apenas 6 deles apresentaram genes ortólogos em Arabidopsis thaliana cuja regulação por estes açúcares ocorreu de maneira similar. Dentre eles, temos o fator de transcrição IAA16, que se mostrou reprimido por sacarose e glicose, constituindo um possível gene de interação entre sinalização por açúcares e auxina. Duas SNFs quinases parálogas de cana-de-açúcar tem como ortólogo um único gene de Arabidopsis thaliana. Os três genes foram reprimidos por sacarose e glicose, sendo outra parte conservada, na via de sinalização a açúcares entre as duas espécies. Outro gene de particular interesse corresponde a uma deidrina, reprimida por sacarose e glicose em cana, assim como seu ortólogo em Arabidopsis e genótipos alto Brix, sugerindo importante papel deste gene em processos relacionados a sinalização/acúmulo de sacarose. Na segunda parte do trabalho, utilizando-se a técnica de microarranjos de cDNA a partir do chip SUCAST, encontramos 55 genes diferencialmente expressos em resposta à sacarose. Destes, apenas 3 apresentaram genes ortólogos de Arabidopsis regulados por açúcar num mesmo sentido que em cana, correspondentes a duas proteínas quinases e a um gene pseudo-response-regulator. Este estudo preliminar identificou genes conservados da sinalização por açúcares em angiospermas que representam possíveis nós importantes das redes de controle relacionadas a carboidratos. O estabelecimento de um possível envolvimento de alguns destes genes no controle da capacidade de acumular mais sacarose no colmo da cana, abriu novas perspectivas na análise molecular desta importante característica. Estudos mais abrangentes são necessários para melhorar os conhecimentos sobre o grau de diversificação da sinalização por açúcares em angiospermas e os valores adaptativos associados.
Abstract: Besides act as carbon primary source in the major types of cells, sugars produced by photosynthesis acquired important functions in the course of plant's evolution like controlling growth, development, and metabolism and acting in resistance to abiotic and biotic stresses like osmotic, energetic and response to pathogens. Sugars can be signals that active signal transduction pathways to change genes expression programs. In order to access the diversification of sugar pathway signaling in angiosperms we conduct comparative analysis of the gene expression in response to sucrose and glucose in seedlings of the monocot Saccharum sp. and the eudicot Arabidopsis thaliana. We also aimed to access the possible correlation between genes related to sucrose storage in sugar-cane and genes related to primary sugar responses. Another aim was to identify deferentially expressed genes in sucrose response. A clearly relation between genes related to sucrose storage in sugar-cane and quickly primary response to sugars was obtained by qRT-PCR analysis. We tested 34 SAS (Sugar Assembled Sequence) related to sucrose storage in sugar-cane and we found that 24 of them were responsive to glucose and/or sucrose. Nine genes showed the same expression pattern (induction or repression) in response to sugar as seen in high Brix genotypes. Six, of this 24 genes, have Arabidopsis orthologues regulated in the same direction (induced or repressed). One is an IAA16 transcription factor that is repressed by both, glucose and sucrose, and may play a role in an integrative pathway of sugar and auxin responses. We also find two SNFs kinases (paralogues) related to a single Arabidopsis ortholog showing the repression response. Another interesting gene is a dehydrin that was repressed in response to sucrose and glucose in sugar-cane and Arabidopsis (its ortholog) and in the high Brix sugar-cane genotypes. It suggests an important role for this dehydrin in processes related to sucrose signaling and storage. In the second part of this work, the sugar-cane cDNA microarray chip, called SUCAST, allow us to identify 55 deferentially expressed in response to sucrose. Only three of these genes have orthologues regulated in same way in sugar-cane and Arabidopsis. These genes correspond to two protein-kinase and a pseudo-response regulator. This preliminary approach leads us to identify conserved genes in sugar signaling among angiosperms that possibly represents important nodes in the regulatory networks in response to sugars. Establishing the involvement of some of these genes in the ability of sucrose storage in sugar-cane's culm will lead us to new perspectives in the molecular basis of this characteristic. More specific works are also needed to improve the knowledge about the real degree of evolutive diversification in sugar signaling among angiosperms and associated genetic fitness.

Full textFloral oils are alternative flower reward to pollen and nectar that are offered by eleven families of angiosperms to oil-collecting bees. The production of this resource appeared at least 28 times, and its collection has been observed in five different lineages of bees. In the Neotropical Region, Malpighiaceae is the most diverse and best known family concerning to the pollination system and the interactions with oil-collecting bees. Plantaginaceae is well known due to some studies mostly on Angelonia and Monttea. In this study, the relationship between the oil-collecting bees and the Plantaginaceae flowers (five species of Angelonia and one of Basistemon) is presented, being given special attention to the morphological aspects of both, the bees behavior during the oil collection and the geographical overlap between the partners of this mutualism. This work presents for the first time the visitors of three species (A. eriostachys, A. goyazensis and Basistemon silvaticus), as well as new data on already studied species (A. cornigera, A. integerrima and A. salicariifolia). It was recorded that the specialized structures that are found on the lip (labellum) of all the known species of Angelonia are associated to the imposition of the correct posture of the visitor and their fixation on the flower. The Basistemon flowers are, in this way, less complex and they present only a discrete median callus. Although the morphology of these structures differ considerably among species, it is possible to establish relationships between their origins. The assemblage of visitors of the flowers of Angelonia and Basistemon varied from three to eighteen species. These species were considered pollinators or illegitimate visitors of the studied species. The bees of the genus Centris were considered the main pollinators of these plants; however species of Tapinotaspidini also play this role. These bees collect oil and pollen, in most species, having as exceptions the genera Centris, Caenonomada e Tapinotaspis that collect only oil. The correct behavior of the visitors of Angelonia and Basistemon flowers, imposed by the floral morphology, results the collection of oil with the forelegs and the contact of their fertile organs with their anterior head or dorsal thorax (in flowers with deep corolla). Some species are morphologically adapted to sample in these flowers, for example, the Centris bees group hyptidis, that have collecting apparatus that diverge from the pattern found in the genera. In respect to the distribution of these plants and their potential pollinators, in some cases, there is a large overlap and the potential pollinators may or may not be specialists in these oil sources. The cases of low geographical congruency show that many of these potential pollinators do not depend only on the oil sources of Angelonia and Basistemon.

Full textIn forest environments, light is the resource that most often limits the growth, survival and reproduction in plants. Thus, the variation in light availability, regarded as one of the most important resources for woody plants in the understory, results in differences in species composition, which segregate in different light niches according to their preferences and tolerances, conferred by their adaptations and phenotypic plasticity. Extant plant traits are not only adapted to the present environment, they are also a legacy from their ancestors and, for that reason, phylogenetically related species often share similar attributes and consequently occupy similar niches, pattern known as phylogenetic conservatism. Recent studies show that functional traits related to the capture of this resource have diversified across different phylogenetic groups, giving them distinct abilities to occupy new light environments. The present study aimed to detect the presence of phylogenetic patterns in species distribution along a light gradient and in ecophysiological responses of eight co-occurring woody species and their respective clades in a forest understory. This was accomplished by comparing the light niche of juvenile plants in response to the existing light gradient, as well as their physiological plasticity in response to understory light variations. We hypothesized that (1) phylogenetic related species have greater similarity of adaptive strategies, and consequently of their niche, than more distantly related ones; and that (2) the niche breadth is wider and (3) traits plasticity is greater in more recent than in more basal clades. The results presented here showed that there is a greater niche similarity between closely related species than between those that are phylogenetically distant, suggesting niche conservatism. Regarding to niche amplitude, there is also a phylogenetic influence but, contrary to our expectations, the older clades showed a greater niche breadth. For plasticity of selected plant traits, results showed no phylogenetic pattern for the studied species and clades, suggesting that other factors act on the phenotypic plasticity of plants, such as ontogenetic effects and/or environmental stress.
