Complete chloroplast genome sequence of an endangered Ottelia cordata and its phylogenetic analysis

Abstract

Ottelia cordata is a typical submerged plant to the family of hydrocharitaceae. In this work, complete chloroplast genome of O. cordata was assembled and characterized from high-throughput Illumina sequencing data. The chloroplasgenome of O. cordatais 157,869bp in length. The O. cordata cp genome encodes 128 functional genes, including 85 protein-coding genes, 35 tRNA genes, and 8 rRNA genes. The GC content of the genome was 36,57%. Its nucleotide composition is asymmetric with an overall A + T content of 63.44%. Phylogenetic analysis indicated that O. cordata is closely related to the Elodea. These results could offer molecular markers and helpful in understanding about the role of O. cordata evolution and protection.
