Characterization of the complete chloroplast genome of Ottelia alismoides (Hydrocharitaceae), a vulnerable submerged macrophyte in China

Abstract

Ottelia alismoides (Linn.) Pers. (Hydrocharitaceae) is an endangered submerged macrophyte in China. In his study, we assembled complete chloroplast (cp) genome of O. alismoides based on the Illumina reads. The cp genome of O. alismoides was 157,885 bp in length, including a large single copy (LSC) region of 87,707 bp and small single copy (SSC) region of 20,234 bp, separated by two inverted repeat (IR) regions of 24,972 bp each. The cp genome encoded 115 genes including 70 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. The GC content of cp genome of O. alismoides is 36.6%. A maximum likelihood phylogenetic analysis revealed that O. alismoides is closely related to O. acuminate var. songmingensis.
