In this study, we first assembled and characterized the complete chloroplast genome of red seaweed It is 190,431 bp in length, with an AT content of 70.56%. In total, 122 genes were identified, and they consisted of 87 protein-coding genes, 33 tRNA genes, and two rRNA genes. The chloroplast genome of did not show an obvious quadripartite structure. A total of five microsatellites (SSRs) were identified in the genome using MISA. Phylogenetic analysis revealed that was first clustered with and in a monophyletic clade that provides useful data for the phylogeny and taxonomy of Rhodymeniophycidae.

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.
