(L.) Müll.Arg. is a well-known folk medicinal plant and found abundantly in South China. The complete chloroplast genome of reported firstly here was 155,630 bp in length, including a large single-copy region with 85,065 bp (LSC), a small single-copy region with 19,441 bp (SSC) and a pair of inverted repeats with 25, 562 bp (IRa and IRb). The plastome was comprised of 112 distinct genes, with 78 protein coding genes, four ribosomal RNA genes and 30 transfer RNA genes. The overall GC content of chloroplast genome was 36.7%. Phylogenetic analysis revealed that was closely related to .

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.
