Characterization of the complete chloroplast genome of Achnatherum pekinense (Poaceae), a widespread weed.

ABSTRACT: Achnatherum pekinense belongs to Poaceae. The complete chloroplast genome of A. pekinense was reported in this study. The chloroplast genome was 137,837 bp in size with a canonical quadripartite structure, including two inverted repeat regions (IR) of 21,635 bp for each, a large single-copy (LSC) region of 81,787 bp in length, and a small single-copy (SSC) region of 12,780 bp in length. The overall guanine-cytosine (GC) content of this chloroplast genome was 38.8%, and the corresponding values of the LSC, SSC, and IR regions were 36.9%, 33.1%, and 44.1%, respectively. A total of 113 unique genes were annotated in this chloroplast genome, including four rRNA genes, 31 tRNA genes, and 78 protein-coding genes. The phylogenetic analysis showed that A. pekinense was clustered with A. inebrians.

Complete chloroplast genomes of Achnatherum inebrians and comparative analyses with related species from Poaceae.

Project description:This article reports the complete chloroplast genome of Achnatherum inebrians, a poisonous herb that is widely distributed in the rangelands of Northern China. The genome is 137 714 bp in total and consists of a large single-copy (81 758 bp) region and small single-copy (12 682 bp) region separated by a pair of inverted repeats (21 637 bp). The genome contains 130 genes, including 84 protein-coding genes, 38 tRNA genes and 8 ribosomal RNA genes, and the guanine + cytosine content is 36.17%. We subsequently performed comparative analysis of complete genomes from A. inebrians and other Poaceae-related species from GenBank. Thirty-eight simple sequence repeats were identified, further demonstrating rapid evolution in Poaceae. Finally, the phylogenetic trees of 37 species of Poaceae and 2 species of Amaranthaceae were constructed by using maximum likelihood and Bayesian inference methods, based on the genes of the complete chloroplast genome. We identified hotspots that can be used as molecular markers and barcodes for phylogenetic analysis, as well as for species identification. Phylogenetic analysis indicated that A. inebrians is a member of the genus Stipa rather than Achnatherum.

The genic regions account for 43.77% of whole cpDNA, and the AT content of the cpDNA was 60.99%. The O. rhizomatis cpDNA encodes 112 unigenes (79 protein-coding genes, four rRNA genes, and 29 tRNA genes). Eighteen genes contain introns, ycf3 contains two introns, and the rest of the gene contains one intron; rps12 is trans-spliced, one of its exons is in the LSC region (5'_end) and the two reside in the IR regions (3'_end) separated. A pair of gene ndhH, due to the 5' part of ndhH which overlaps the IR/SSC junctions, was two unique genes. The four rRNA genes are all located in the IR. Phylogenomic analysis showed that O. rhizomatis is closely related to O. officinalis. The new data will help to determine the phylogenetic placement of the genus Oryza and fill gaps in our understanding of Oryzae biology.
