The complete chloroplast genome of cultivar Sa (a modern Sudan grass cultivar) was sequenced and analyzed in the present study. The chloroplast genome is 140,754 bp in length and includes a large single-copy region 82,688 bp in length, a small single-copy region 12,503 bp, and two inverted repeat regions 22,782 bp each. The genome contains 104 unique genes, including 4 rRNAs, 29 tRNAs, and 71 protein-coding genes. The phylogenetic analysis showed that Sudan grass cultivar Sa in a clade with five other complete chloroplast genomes of . The work facilitates studies on population genetic structure and phylogenetic relationships in genus .
在本研究中，对栽培品种Sa（一种现代苏丹草栽培品种）的完整叶绿体基因组进行了测序和分析。叶绿体基因组长度为140,754 bp，包括一个长度为82,688 bp的大单拷贝区域、一个长度为12,503 bp的小单拷贝区域和两个长度均为22,782 bp的反向重复区域。该基因组包含104个独特基因，包括4个rRNA、29个tRNA和71个蛋白质编码基因。系统发育分析表明，苏丹草栽培品种Sa与其他五个完整叶绿体基因组处于一个进化枝中。这项工作有助于对该属的种群遗传结构和系统发育关系进行研究。
