Abstract

Lianas are a very expressive component of the tropical flora, often representing the majority of species richness and biomass. Despite this great relevance, lianas are still poorly understood by the Botanical science, and are often seen as a disturbing or subsidiary element in forests. This team of researchers views lianas as an important component of the forest community, and highlights issues of outstanding scientific importance: 1. What are the genetic mechanisms regulating the cessation of self-supporing xylem formation and the onset of linanescent vascular syndrome formation in lianas; 2. How are the different anatomical architectures of lianas related to the biomechanics and conductivity of the vascular system; 3. How the growth of lianas in forests can be shaped by their functional aspects; 4. How the fall of lianas impact their mortality, regeneration, and structure. Considering these topics, the present project proposes an approach that is both broad and detailed, to fill numerous gaps in the biology of lianas, with the study of 16 species encompassing the Bignoniaceae and Leguminosae families. This approach will be carried out in two scales: one that has a global scope, generating data that can be extrapolated for the lianas as a whole, such as functional and biomechanical aspects, related to the vascular anatomy and growth dynamics. This will be accomplished with two-level approach: one more global, as well as the understanding of the functional and biomechanical aspects of the vascular system related to its lianescent anatomy and its growth dynamics. In a second level we will use a model species (Bignonia magnifica, Bignoniaceae) to explore innovative knowledge on the gene regulation of the formation of the lianescent vascular syndrome of its xylem. The final result will be a robust and integrated body of knowledge available for the academic community and the public in general, involving genetic, anatomical and ecofunctional aspects. (AU)
