Mitochondrial DNA B Resour. 2020 Jan 22;5(1):774-775. doi: 10.1080/23802359.2020.1715872.

Abstract

Begonia fimbristipula is a plant of perennial flowering plants in the family Begoniaceae. In this article, the complete chloroplast genome of B. fimbristipula was studied and illustrated to add more genetic information. The chloroplast genome is 169,436 bp in length as the circular, which exhibits a large single-copy region (LSC) of 77,058 bp, a small single-copy region (SSC) of 18,128 bp, and a pair of inverted repeat regions (IRs) of 37,123 bp in each. The overall nucleotide composition of chloroplast genome is: 31.8% A, 32.6% T, 18.0% C, 17.5% G, and the total GC content 35.5%. A total of 142 genes were annotated that included 91 protein-coding genes (PCGs), 43 transfer RNA (tRNAs), and 8 ribosome RNA (rRNAs). Phylogenetic relationship shows that Begonia fimbristipula is more closely related to Begonia pulchrifolia on genetic relationships using the Maximum-Likelihood (ML) method.
