is a common and annual the Traditional Chinese Medicine for many years in China. In this study, we presented the complete chloroplast genome of . The chloroplast genome size was 151,897 bp in length that contained a large single-copy region (LSC) of 83,847 bp, a small single-copy region (SSC) of 17,890 bp and two inverted repeat regions (IR) of 25,080 bp. The overall nucleotide composition of the chloroplast genome is: 31.2% of A, 31.3% T, 18.5% C and 19.0% G, with a total G + C content of the chloroplast genome 37.5% and A + T of 62.5%. The chloroplast genome of contains 133 genes, which included 88 protein-coding genes (PCG), 37 transfer RNA (tRNAs), and 8 ribosome RNA (rRNAs). Phylogenetic neighbour-joining (NJ) analysis result shown that the position of closely related to in evolutionary relationship.

Background: Populus tomentosa, known as Chinese white poplar, is indigenous and distributed across large areas of China, where it plays multiple important roles in forestry, agriculture, conservation, and urban horticulture. However, limited accessibility to the mitochondrial (mt) genome of P. tomentosa impedes phylogenetic and population genetic analyses and restricts functional gene research in Salicaceae family.

Background: The St-genome-sharing taxa are highly complex group of the species with the St nuclear genome and monophyletic origin in maternal lineages within the Triticeae, which contains more than half of polyploid species that distributed in a wide range of ecological habitats. While high level of genetic heterogeneity in plastome DNA due to a reticulate evolutionary event has been considered to link with the richness of the St-genome-sharing taxa, the relationship between the dynamics of diversification and molecular evolution is lack of understanding.
Results: Here, integrating 106 previously and 12 newly sequenced plastomes representing almost all previously recognized genomic types and genus of the Triticeae, this study applies phylogenetic reconstruction methods in combination with lineage diversification analyses, estimate of sequence evolution, and gene expression to investigate the dynamics of diversification in the tribe.

Background: Zanthoxylum L., an important genus in the Rutaceae family, has great edible and medical values. However, the high degree of morphological similarity among species and the lack of sufficient chloroplast (cp) genomic resources have greatly impeded germplasm identification and phylogenetic analyses of
Methods: Here we assembled cp genomes of five widespread species (, , , and ) in China as a case study, comparative analysis of these assembled cp genomes.
