Chloroplast genome structure and phylogenetic position of Ruppia sinensis Shuo Yu & den Hartog. Issue 2 (3rd July 2019) - Yu, Shuo
Abstract: Ruppia is widely distributed in marine and inland saline habitats in temperate and tropical regions. In this study, the complete chloroplast genome sequence of R. sinensis was successfully obtained using Illumina sequencing. The full length of the chloroplast genome length was 158, 897 bp with a typical quadripartite structure: one large single copy (LSC) region (88, 952 bp), one small single copy (SSC) region (19, 047 bp), and a pair of inverted repeats (IR) (25, 449 bp each). The GC content of this genome was 35.9%. The whole genome contained 136 genes, including 88 protein-coding genes, 40 tRNA genes, and eight rRNA genes. Phylogenetic analysis indicated that R. sinensis formed a distinct clade, being separated from Zostera marina and Potamogeton perfoliatus .
