Abstract
Ottelia acuminata var. songmingensis is an Endangered freshwater submerged macrophyte occupying only a portion of a stream ca. 300 meters long in Songming County of the Yunnan Province, China. Here, we report and characterize the complete chloroplast genome sequence of O. acuminata var. songmingensis to provide genomic resources useful for promoting its conservation. The complete chloroplast genome is 157,645 bp in length, consisting of a pair of inverted repeat (IR) regions (24,973 bp), a small single copy (SSC) region (20,055 bp), and a large single copy (LSC) region (87,644 bp). The chloroplast genome contained 116 genes, including 71 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. The overall GC content of the whole genome is 36.6%. Phylogenetic analysis of 19 selected chloroplast genomes revealed that O. acuminata var. songmingensis was closely related to Elodea canadensis of Hydrocharitaceae.
