Title : Genetic diversity in natural populations of Myrciaria floribunda in the state of Alagoas, Brazil


There is an indiscriminate exploitation of Brazil's natural resources. As it comes occurring, purely exploratory, has contributed unfavorably to the maintenance of these ecosystems, with the eminent need for their conservation, in addition to recovery of already devastated areas. A practical example of this fact is related to the Mata Atlantic, where the conservation of this ecosystem is considered a priority for the maintenance of biological diversity on the American continent. This recognition is mainly due to high species richness, combined with significant levels of endemism and a high degree of fragmentation of their environments. Among the tree species occurring in this Biome, Myrciaria floribunda, commonly known as cambuí, is relevant both ecological and socio-economic. Studies on ecology and population genetics are fundamental to understanding the effects of fragmentation on forest species. A study marker-based ISSR was performed to estimate genetic diversity parameters and spatial genetic structure, in a natural population of Myrciaria floribunda, aiming at programs conservation and genetic improvement. The collections were carried out in natural populations of the State of Alagoas, more specifically, in the municipalities of Penedo, Piaçabuçu and Feliz Desert. Young leaves were used to carry out ISSR analyses. These were collected from 30 individuals in each population. With the results obtained, it was possible to understand the potential of these individuals for in situ conservation, collection of seeds to form germplasm banks, as well as for the recovery of degraded areas and future genetic improvement programs, so that future generations have access to the biodiversity we have today.
