Abstract

Begonia guangxiensis was assessed as endangered according to Red List of Chinese Plants. In this study, we described the complete plastid genome of B. guangxiensis. The plastid genome sequence of B. guangxiensis is 157,648 bp in size, having a large single-copy region (LSC) of 86,514 bp, a small single-copy region (SSC) of 18,076 bp, and two inverted repeat (IR) regions of 26,529 bp. The complete plastid genome of B. guangxiensis encoding 112 unique genes including 79 protein-coding genes, 29 tRNA genes, and four rRNA genes. The overall GC content of the plastid genome is 35.9%. Phylogenetic analysis confirmed that B. guangxiensis is closely related to B. varipeltata.
