Abstract

Pyankovia brachiata (Pall.) Akhani & Roalson 2007, is an annual plant belonging to the genus Pyankovia, family Amaranthaceae, which is widely distributed in the inland deserts of Northwest China. P. brachiata was previously categorized under the genus Salsola in Salsoleae and has been a long-standing topic of debate. Therefore, the complete chloroplast genome of P. brachiata must be studied to provide a theoretical reference for species classification. In this study, we sequenced P. brachiata samples and determined the species' complete chloroplast genome. The complete chloroplast genome was 149,922 bp in length, with one large single copy (LSC: 83,565 bp), one small single copy (SSC: 18,535 bp), and two inverted repeat regions (IRa and IRb, 23,911 bp each). It contains 132 genes, including 87 protein-coding, eight rRNA, and 37 tRNA genes. The phylogenetic position showed that P. brachiata has the closest relationship with Caroxylon passerinum (accession number: NC057191.1). This study will provide genetic information and be beneficial to understanding the systematic position of P. brachiata within the Amaranthaceae.

中国一年生沙漠植物 Pyankovia brachiata（苋科）的完整叶绿体基因组。

Pyankovia brachiata (Pall.) Akhani & Roalson 2007 是苋科 Pyankovia 属的一年生植物，广泛分布于中国西北的内陆沙漠。P. brachiata 以前被归入 Salsoleae 中的 Salsola 属，长期以来一直是一个争论不休的话题。因此，必须研究蕨麻的完整叶绿体基因组，为物种分类提供理论参考。在本研究中，我们对 P. brachiata 样品进行了测序，并确定了该物种的完整叶绿体基因组。完整的叶绿体基因组长度为 149,922 bp，包括一个大的单拷贝（LSC：83,565 bp）、一个小的单拷贝（SSC：18,535 bp）和两个倒位重复区（IRa 和 IRb，各 23,911 bp）。它包含 132 个基因，包括 87 个编码蛋白质的基因、8 个 rRNA 基因和 37 个 tRNA 基因。系统发生位置显示，P. brachiata 与 Caroxylon passerinum（登录号：NC057191.1）的关系最为密切。这项研究将提供遗传信息，并有助于了解 P. brachiata 在苋科植物中的系统位置。
