The complete chloroplast genome of a well-known medicinal herb, Senna tora

Abstract

Senna tora has been used as a famous traditional medicine both in China and India to treat skin diseases, cough, hepatitis, fever, and hemorrhoids. Here, the complete chloroplast (cp) genome sequence of S. tora was reported and characterized for the first time. The cp genome is 162,426 bp in length, with a large single copy (LSC) region of 90,673 bp and a small single copy (SSC) region of 18,001 bp separated by a pair of 26,791 bp inverted repeat (IR) regions. There were 130 predicted genes including 85 protein-coding genes, 37 tRNA genes, and eight rRNA genes in the genome, and the overall GC content of the genome is 36%. The phylogenetic analysis based on the cp genome data indicated that S. tora was closer to S. occidentalis.
