Abstract

This study determined the chloroplast genome of Thalictrum atriplex, which is 155,984 base pairs (bp) in length, including one large single-copy (LSC) region of 85,422 bp, one small single-copy (SSC) region of 17,594 bp, and two inverted repeat (IR) regions of equal length (26,484 bp each). The total guanine-cytosine (GC) content was 38.35%. A total of 127 genes were identified, including 83 protein-coding genes, eight ribosomal RNA (rRNA) genes, and 37 transfer RNA (tRNA) genes. Phylogenetic analysis revealed that T. atriplex and T. finetii are closely related, forming a monophyletic clade, which provides a basis for the phylogenetic study and resource utilization of T. atriplex.

毛茛科凤梨属植物叶绿体全基因组的研究。

本研究确定了Thalictrum atriplex的叶绿体基因组长度为155,984个碱基对（base - pair, bp），包括一个85,422 bp的大单拷贝（large -单拷贝）区域，一个17,594 bp的小单拷贝（small -单拷贝）区域，以及两个长度相等的反向重复（inverted repeat， IR）区域（各26,484 bp）。总鸟胞嘧啶（GC）含量为38.35%。共鉴定出127个基因，其中蛋白编码基因83个，核糖体RNA （rRNA）基因8个，转移RNA （tRNA）基因37个。系统发育分析结果表明，三叶滴虫与有限滴虫亲缘关系密切，构成单系支系，为三叶滴虫的系统发育研究和资源利用提供了依据。
