The family Chenopodiaceae Vent. (Amaranthaceae .) is known for its taxonomic complexity, comprising species of significant economic and ecological importance. Despite its significance, the availability of plastid genome data for this family remains limited. This study involved assembling and characterizing the complete plastid genomes of four Thunb. species within the tribe Salsoleae ., utilizing next-generation sequencing technology. We compared genome features, nucleotide diversity, and repeat sequences and conducted a phylogenetic analysis of ten Salsoleae . species. The size of the plastid genome varied among four species, ranging from 150,777 bp () to 151,307 bp (). Each studied plastid genome encoded 133 genes, including 114 unique genes. This set of genes includes 80 protein-coding genes, 30 tRNA genes, and 4 rRNA genes. Eight divergent regions (, , , , , , , and ) were identified in ten Salsoleae . plastid genomes, which could be potential DNA-barcoding markers. Additionally, 1106 repeat elements were detected, consisting of 814 simple sequence repeats, 92 tandem repeats, 88 forward repeats, 111 palindromic repeats, and one reverse repeat. The phylogenetic analysis provided robust support for the relationships within species. These data represent a valuable resource for future phylogenetic studies within the genus.
藜科（苋科。）以其分类学复杂性而闻名，包含具有重要经济和生态意义的物种。尽管其具有重要性，但该科质体基因组数据的可用性仍然有限。本研究利用下一代测序技术，对盐角草族内的四种滨藜属物种的完整质体基因组进行了组装和特征分析。我们比较了基因组特征、核苷酸多样性和重复序列，并对十种盐角草属物种进行了系统发育分析。四种物种的质体基因组大小各不相同，范围从150,777碱基对（）到151,307碱基对（）。每个研究的质体基因组编码133个基因，包括114个独特基因。这组基因包括80个蛋白质编码基因、30个tRNA基因和4个rRNA基因。在十种盐角草属质体基因组中鉴定出八个差异区域（、、、、、、和），它们可能是潜在的DNA条形码标记。此外，检测到1106个重复元件，包括814个简单序列重复、92个串联重复、88个正向重复、111个回文重复和1个反向重复。系统发育分析为物种间的关系提供了有力支持。这些数据是该属未来系统发育研究的宝贵资源。
