is an ornamental and medicinal plant that is widely cultivated. The complete chloroplast genome of was sequenced using Illumina Hiseq X Ten platform. The chloroplast genome was 158,080 bp in length, containing two short inverted repeat (IRa and IRb) regions of 26,385 bp, which was separated by a large single copy (LSC) region of 86,270 bp and a small single copy (SSC) region of 19,040 bp. The GC content of the whole chloroplast genome was 36.8%. The chloroplast DNA of comprised 112 distinct genes, including 78 protein-coding genes, 4 ribosomal RNA genes and 30 transfer RNA genes. Phylogenetic analysis indicated that all species of formed a monophyletic group, was closely related 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.

Background And Aims: Nekemias is a small genus of the grape family, with nine species discontinuously distributed in temperate to subtropical zones of the Northern Hemisphere but mostly in East Asia. Previous phylogenetic studies on Nekemias have mainly based on a few chloroplast markers, and the phylogenetic framework and systematic relationships are still highly contested.
Methods: We carried out a systematic framework reconstruction of Nekemias and intra-generic reticulate evolutionary analyses based on extensive single-copy nuclear and chloroplast genomic data obtained by the Hyb-Seq approach, combining genome skimming and target enrichment.

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.
