Genetic Diversity and Population Structure of Capirona (Calycophyllum spruceanum Benth.) from the Peruvian Amazon Revealed by RAPD Markers

Capirona (Calycophyllum spruceanum Benth.) is a tree species of commercial importance widely distributed in South American forests that traditionally used for its medicinal properties and wood quality. Studies on this have been focused mainly properties, propagation, growth. However, genetic studies capirona very limited to date. Currently, it possible explore diversity population structure fast reliable manner by using molecular markers. We here 10 random amplified polymorphic DNA (RAPD) markers analyze the 59 samples were sampled from four provinces located eastern region Peruvian amazon. A total 186 bands manually scored, generating × presence/absence matrix. dendrogram was generated UPGMA clustering algorithm, and, similar principal coordinate analysis (PCoA), showed groups correspond geographic origin (LBS, Irazola, Masisea, Iñapari). Similarly, discriminant components (DAPC) STRUCTURE confirmed grouped into clusters. we also noticed few intermingled. Genetic estimation conducted considering (populations) identified software. AMOVA revealed greatest variation within populations (71.56%) indicated variability among 28.44%. Population divergence (Fst) between clusters 1 4 highest difference (0.269), lowest Fst observed 3 (0.123). RAPD successful effective. more are needed, employing other tools. To best our knowledge, first investigation Peru natural distribution, as such hoped helps pave way towards improvement urgent sustainable management Peru.
