Abstract

The complete chloroplast genome sequence of Senna tora was characterized from Illumina pair-end sequencing. The chloroplast genome of S. tora was 161,050 bp in length, containing a large single-copy region (LSC) of 90,411 bp, a small single-copy region (SSC) of 18,537 bp, and two inverted repeat (IR) regions of 26,050 bp. The overall GC content is 36.20%, while the correponding values of the LSC, SSC, and IR regions are 64.5%, 69.4%, and 60.2%, respectively. The genome contains 129 complete genes, including 8 rRNAs, 37 tRNAs and 84 protein coding genes. The Neighbour-joining phylogenetic analysis showed that S. tora and S. bicapsularis clustered together as sisters to other Senna species.

摘要

番泻叶的完整叶绿体基因组序列由Illumina的双末端测序来表征。S. tora的叶绿体基因组长度为161,050 bp，包含90,411 bp的大单拷贝区域（LSC），18,537 bp的小单拷贝区域（SSC）和26,050的两个反向重复（IR）区域bp。总GC含量为36.20％，而LSC，SSC和IR区域的对应值分别为64.5％，69.4％和60.2％。该基因组包含129个完整基因，包括8个rRNA，37个tRNA和84个蛋白质编码基因。邻居结合的系统发育分析表明，S。tora和S. bicapsularis聚在一起，成为其他番泻叶物种的姐妹。
