- Abstract
Genetic diversity and structure of Senna reticulata. S. reticulata (Willd.) H. S. Irwin & Barneby is a pioneer tree that grows in open areas of the Amazon floodplains and is often used as a medicinal plant species. Due to the lack of information on diversity for this species, this research aimed to characterize the genetic diversity of natural populations of S. reticulata by AFLP markers. The samples were collected in four populations along the natural gas pipeline pathway of Coari-Manaus: Santa Luzia do Baixio, Nossa Senhora de Nazaré, Matrinchã and Esperança II. Four AFLP primers were used, resulting in a total of 330 polymorphic loci ranged from 76.97% to 92.42% among populations. The clustering and Bayesian cluster analysis allowed to discriminate a group composed by the Nossa Senhora de Nazaré and Esperança II populations and another group composed by Santa Luzia do Baixio. Matrinchã population was characterized as a gene composition from both groups. Average gene flow among populations was 4.04 and Mantel test showed low correlation (r = 0.268) between the pairwise of geographic and genetic distance matrices. According to molecular variance analysis, the most genetic differentiation is within populations (82.29%), while the inter population variation was around 17.71%.
