Phylogenetic study on some species of Fabaceae using morphological traits and sequence related amplified polymorphism (SRAP) markers

Echinosophora koreensis Nak. 1923 is a plant species endemic to Korean peninsula, belonging to the genus Sophora L. of the Fabaceae family. In this study, a phylogenetic study was carried out on 13 species of 11 genera of Fabaceae distributed in DPR Korea. Morphological differences of these species of Fabaceae were analyzed based on their typical traits such as leaf, flower and fruit, and compared to the molecular phylogenetic tree constructed by unweighted pair group method with arithmetic mean (UPGMA) method based on sequence related amplified polymorphism (SRAP) markers. The results of morphological comparative analysis of leaf, flower and fruit traits and the genetic structure obtained using STRUCTURE HARVESTER V. 2.3.4. software (K = 11) support the taxonomic status of E. koreensis as a single species of its genus.
