Abstract

The species Casearia sylvestris Sw (Salicaceae) is an important representative of the Casearia Jacq. genus, due to its chemical, pharmacological, economic, environmental and biotechnological aspects. Because of its high adaptive capacity, this species is widespread in Central and South America and, in Brazil, it occurs in practically all biomes. The morpho-anatomical, chemical and genetic data available on C. sylvestris, indicate close relationship between the variety "lingua" and the Cerrado biome, and between the variety "sylvestris" and Atlantic Forest. Also, there are data describing significant genetic differences between these two varieties. In ecotones Cerrado/Atlantic Forest, it can be found these two varieties, including individuals with intermediate characteristics, considering both morpho-anatomical and genetic ones. There is evidence that in C. sylvestris var. "lingua"/Cerrado occur predominantly the phenolic compounds, while in C. sylvestris var. "sylvestris"/Atlantic Forest the clerodane diterpenes predominate. So, taking part in the thematic network CECAA - "Prospecção de moléculas bioativas e estudo de variabilidade infra-específica em plantas e microrganismos endofíticos do Cerrado e Caatinga - Contribuição para o conhecimento e uso sustentável da biodiversidade brasileira." (CNPq 563311/2010-0 and FAPESP 2010/52327-5), the main objective of this project is to evaluate the hypothesis that the chemical composition, considering the secondary metabolites, is related to and / or conditioned by biomes, and mainly associated to their predominant morphotypes and, therefore, under strong genetic control. If this hypothesis is proven, individuals with differential production of clerodane diterpenes (type casearinas) can be used for comparative proteomic studies aiming the identification of enzymes related to the biosynthesis of these important metabolites.
