Complete chloroplast genome sequence of Oxytropis glabra (Leguminosae)

Abstract

Oxytropis glabra DC. is a perennial poisonous plant to livestock belonging to the genus Oxytropis, Leguminosae, mainly distributed in Northwestern China. As a poisonous grass, this species protects plant diversity in degraded grasslands by sheltering adjacent plants. In this study, the complete chloroplast genome with a total size of 122,094 bp was reported. Our annotations showed that the chloroplast genome contains 109 genes, including 76 protein-coding genes, 29 tRNA genes, and four rRNA genes. This work presents complete chloroplast genome information, which will be valuable for studying the evolution and genetic diversity of O. glabra.

The plastome of ArcticOxytropis arctobia(Fabaceae) is significantly different from that ofO. splendensand other related species

“…To date, the plastomes of O. bicolor (MN255323; Su et al 2019) and O. glabra (MW349014; Liu et al 2021) are the only previously completed sequences from the genus Oxytropis, while there are 32 available plastome sequences from the closely related genus Astragalus (Lei et al 2016;Wang et al 2016;Choi et al 2016;Zhang et al 2020;Duan et al 2020;Liu et al 2020;Charboneau et al 2021). Although there were many similarities in size and gene content between the plastomes of Oxytropis and Astragalus (Table 1), several distinctive differences were observed, particularly in the plastome of O. arctobia.…”

“…Several plastomes have been sequenced in this clade, including many economically important species such as Cicer arietinum (Jansen et al 2008), Pisum sativum, Lathyrus sativus (Magee et al 2010), Lens culinaris, Vicia faba, and several species of Trifolium (Sabir et al 2014), in which several inversions and gene or intron losses have been identified. Among the extensive genus Oxytropis, only two plastomes have been sequenced previously: O. bicolor (Su et al 2019) and O. glabra (Liu et al 2021), whereas in the closely related genus Astragalus, 32 different plastid genomes are available (Lei et al 2016;Wang et al 2016;Choi et al 2016;Zhang et al 2020;Duan et al 2020;Liu et al 2020;Charboneau et al 2021). In this study, we sequenced and assembled the plastomes of two diploid species of Oxytropis from contrasting environments: O. arctobia Bunge (synonym of Oxytropis nigrescens var.…”
