The complete chloroplast genome of Dianella ensifolia (Asphodelaceae)

Dianella ensifolia (L.) Redouté 1802 is a plant known for its significant medicinal values. In this study, we presented its chloroplast genome. The length of the chloroplast genome was found to be 156,571 bp, with a GC content of 37.86%. It consisted of a large single-copy (LSC) of 85,318 bp and a small single-copy (SSC) of 18,307 bp, a pair of inverted repeats (IRs) of 26,473 bp each that separated the LSC and SSC regions. The chloroplast genome of D. ensifolia consisted of 114 unique genes, including 80 protein-coding genes, four rRNA genes, and 30 tRNA genes. Through phylogenetic analysis, we identified a close relationship between D. ensifolia and D. nigra. This newly sequenced chloroplast genome not only enhances our understanding of the genome of Dianella, but also provides valuable insights for the evolutionary study of the family Asphodelaceae.

Dianella ensifolia (L.) Redouté 1802，亦称红荛花，以其显著的药用价值而闻名。在本研究中，我们阐述了其叶绿体基因组。叶绿体基因组的长度为156,571碱基对，GC含量为37.86%。该基因组由一段85,318碱基对的大单拷贝（LSC）和一段18,307碱基对的小单拷贝（SSC）组成，两侧各有一对反向重复序列（IRs），每对长度为26,473碱基对，分别分隔LSC和SSC区域。D. ensifolia的叶绿体基因组包含114个独特的基因，其中80个为蛋白质编码基因，4个为rRNA基因，以及30个tRNA基因。通过系统发育分析，我们确定了D. ensifolia与D. nigra之间的密切关系。这一新测序的叶绿体基因组不仅加深了我们对Dianella基因组结构的理解，还为Asphodelaceae科进化研究提供了宝贵的洞见。
