(Amarathaceae) has been commonly used as a traditional Chinese medicine in the treatment of osteoporosis and bone nonunion. Here, the complete chloroplast genome of was assembled and characterized. The cp genome is 151,451 bp in length, composed of a pair of 25,150 bp inverted repeat (IR) regions separated by a large single-copy (LSC) region of 83,899 bp and a small single-copy (SSC) region of 17,252 bp. The whole cp genome of . contains 130 genes(85 protein-coding genes, 37 tRNAs and eight rRNAs) and the overall GC content is 36.5%. Phylogenetic analysis based on the cp genome data showed that . was close to .

Background: Rice bean (Vigna umbellata), an underrated legume crop, demonstrates strong adaptability to poor soil fertility and has significant potential to enhance global food security. It is valuable both as a vegetable and fodder crop due to its high protein content, essential fatty acids, and micronutrients. Despite the sequencing of a high-quality genome of rice bean, its mitochondrial genome (mitogenome) sequence has not yet been reported.
is one of the two genera in the large fern family Aspleniaceae. A previous study explored the molecular phylogeny of this genus using several chloroplast DNA fragments and identified three major clades, one of which is the monophyletic Old World clade with southwestern China as its diversity center. To date, there were only a few studies conducted on chloroplast genomes in or Aspleniaceae, limiting the understanding of the plastome features and its role in evolution of this group.

Background: The genus Impatiens, which includes both annual and perennial herbs, holds considerable ornamental, economic, and medicinal value. However, it posed significant challenges for taxonomic and systematic reconstruction. This was largely attributed to its high intraspecific diversity and low interspecific variation in morphological characteristics.
Background: Pueraria is an edible and medicinal raw material, which is of great value to the pharmaceutical and food industries. Nonetheless, due to morphological diversity and complex domestication history, the classification of Pueraria plants is ambiguous. As the varieties on the market are mixed, the species are difficult to distinguish, and their morphological characteristics are similar to the physical and chemical properties.
Background: Numerous species of Ardisia are widely used for their medicinal and ornamental values in China. However, accurately identifying Ardisia species at the molecular level remains a challenge due to the morphological similarities among different species, the complexity of interspecific variation, and the limited availability of genetic markers. In this study, we reported 20 chloroplast genomes of Ardisia species from China and combined them with 8 previously published chloroplast genomes to conduct a comprehensive analysis for phylogenetic relationships and adaptive evolution.
