Comprehensive analysis of the chloroplast genome structure and phylogeny of  Glochidion puberum (L.) Hutch.

Glochidion puberum (L.) Hutch., a member of the family Phyllanthaceae, is widely distributed in China and possesses both medicinal and ornamental value. Despite its ecological and economic significance, the complete chloroplast genome of G. puberum had not been reported, and its phylogenetic placement within the genus Glochidion has remained unresolved. In this study, we assembled and annotated the complete chloroplast genome of G. puberum for the first time. The chloroplast genome is 157,133 bp in length, exhibiting an overall GC content of 37% and containing 129 genes. The result of phylogenetic analysis revealed a close evolutionary relationship among G. puberum, G. hirsutum, and G. chodoense based on complete chloroplast genome. These findings provide comprehensive genomic data for G. puberum and offer new perspectives on the phylogenetic relationships and evolutionary position in the broader Phyllanthaceae family.
