Alguns gêneros e espécies nativas do Brasil, como Cattleya, são apreciados e têm elevado valor econômico devido à capacidade de recombinação genética, beleza, forma, tamanho e durabilidade de suas flores. Contudo, muitas dessas espécies e gêneros encontram-se em risco de extinção, o que as torna objeto para diversos estudos. Técnicas biotecnológicas de cultivo in vitro (germinação assimbiótica de sementes e micropropagação) são

Abstract:

There is considerable evidence that pollinator shifts can explain many differences in flower morphology between closely related plant species, but the extent to which pollinator shifts can explain the maintenance of among-population variation in floral traits within species is poorly known. In this thesis, I combined comparative and experimental approaches to examine the evolution of floral traits in the moth-pollinated orchid Platanthera bifolia. More specifically, I investigated (1) the relationship between flower and pollinator morphology, (2) phenotypic selection on morphology and phenolog

Abstract:

A key question in biology is how changes in gene function or regulation produce new morphologies during evolution. The nectar spur is an evolutionarily labile structure known to influence speciation in a broad range of angiosperm taxa. Here, the genetic basis of nectar spur development, and the evolution of differences in nectar spur morphology, is investigated in Linaria vulgaris and two closely related species of orchid, the primitively longer-spurred Dactylorhiza fuchsii, and more derived short-spurred D. viridis (Orchidinae, Orchidaceae).

Abstract:

There are few other structures in nature from which evolution has generated such wide diversity as the flower or inflorescence, and this diversity is commonly attributed to the influence of their animal visitors. By outsourcing their mate choice to pollinators, plants have left themselves - and especially their flowers - subject to the selective forces imposed by the behaviour, cognition and perception of the pollinators that serve them. The orchids provide some of the most remarkable and extreme examples of adaptations to specific animal pollinators. Perhaps one of the most peculiar of thes

The main scent components of P. bellina are monoterpenes including linalool and geraniol with the maximal emission on day 5 post anthesis (D+5). The key enzyme gene for monoterpene biosynthesis in P. bellina is geranyl diphosphate synthase small subunit (PbGDPS_SSU), whose expression is concomitant with the maximal emission of floral scent. Previously, the floral scent production was detected mainly from 10 am to 4 pm for P. bellina. It is possible that the floral scent emission was either li

Abstract:

Orchids provide a model system for addressing evolutionary and ecological questions both because of their species diversity, and because the packaging of their pollen into pollinia facilitates the estimation of male and female pollination success. This thesis focuses on the ecology and evolution of pollination systems in the African orchid genus Eulophia, with an emphasis on deceptive pollination, mechanisms promoting cross-pollination, and pollinatordriven speciation. Pollination in the deceptive species E. zeyheriana is shown to depend on flower colour and proximity to the rewarding model sp
