The chloroplast genome of Sonneratia ovata: genome structure and comparative analysis

Abstract

Sonneratia ovata is one of the most widely distributed mangrove species worldwide. In this study, the complete chloroplast (cp) genome of S. ovata was sequenced and assembled; its phylogenetic position was confirmed in Lythraceae. The total size of cp genome was 153,052 bp, exhibiting a typical quadripartite structure with a large single copy (LSC) region of 87,238 bp and a small single copy (SSC) region of 18,002 bp, two inverted repeats (IRs) regions of 23,906 bp each. The overall GC content was 37.3%, respectively. We detected 128 genes in cp genome, including 84 protein-coding genes, 36 tRNA genes, and 8 rRNA genes. A phylogenetic analysis showed that S. ovata has a close relationship with S. apetala within the genus Sonneratia.
