The complete plastome ofPolytrichum communeHedw. (Polytrichaceae, Bryophyta)

Abstract

Polytrichum commune, one of hair-cap mosses, is the type species of the genus Polytrichum Hedw. (Polytrichaceae). Here we present its complete plastome. The plastome of P. commune is successfully assembled from raw reads sequenced by HiSeq X ten system. Its total length is 126,323 bp consisting of four regions: large single copy (LSC) region (88,070 bp), small single copy (SSC) region (16,717 bp), and inverted repeats (IRs; 9,680 bp per each). It contains 128 genes (84 coding genes, eight rRNAs, and 36 tRNAs); nine genes (four rRNAs and five tRNAs) are duplicated in IR regions. The overall GC content is 28.9% and in the LSC, SSC and IR regions is 26.1%, 25.1%, and 45.5%, respectively. This plastome is an important sequence resource for further studies on the class Polytrichopsida.

“…DNA extraction, sequencing, assembly and annotation . The sample preparation, sequencing, and chloroplast genome and nuclear DNA assembly followed protocols used in earlier studies (Jin & Zhu 2021; Xiang et al 2022). The chloroplast genomes were annotated automatically using CPGAVAS2 (Shi et al 2019) and then adjusted using Geneious v.11.1.5 (Kearse et al 2012) based on the Chorisodontium aciphyllum (Hook.f.…”
