Sequencing and phylogenetic analysis of the complete chloroplast genome of Cassia tora Linn.

ABSTRACT: Cassia tora Linn. is widely distributed in South-East Asia and South-West Pacific as an important weed. It has many pharmacological activities including anti-allergic, anti-hepatotoxic, and remedy in skin diseases. In this study, we assembled and characterized the complete chloroplast genome sequence of C. tora from high-throughput sequencing data. The chloroplast genome was 162,426?bp in length, consisting of large single-copy (LSC) and small single-copy (SSC) regions of 90,843?bp and 18,001?bp, respectively, which were separated by a pair of 26,791?bp inverted repeat (IR) regions. The genome is predicted to contain 131 genes, including 84 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. The overall GC content of the genome is 36.0%. A phylogenetic tree reconstructed by 32 chloroplast genomes reveals that C. tora is mostly related to Senna occidentalis. The work reported the firstly complete chloroplast genome of C. tora which may provide useful information to the evolution of Cassieae Bronn.
