Genetic variation of Anisoptera costata Korth in Tan Phu tropical forest, Dinh Quan district, Dong Nai province

Anisoptera costata Korth, an endangered species is distributed in lowland tropical forests of southern Vietnam. Habitat loss and over-exploitation are the major reasons for threatening this species. Eight polymorphic microsatellite markers were used to analyze 64 adult trees from three A. populations Tan Phu, Dinh Quan district, Dong Nai Province Southeast Vietnam detect effects deforestation on gene flow differentiation among forests. The results showed that all have moderate levels genetic diversity within with mean values observed expected heterozygosities, 0.242 0.269, respectively, (0.179), indicating limited (Nm = 1.15). Analysis molecular variance indicated high variation (64.68%) structure Phu. Bayesian analysis detected two lineages, cluster 1 including one population Mieu Co Nam 2 populations, Thac Mai Bau Nuoc. These contribute understanding Southeastern will provide guidelines conservation, management resoration
