Characterization of the complete plastid genome of of Veronica eriogyne H. Winkl., a Tibetan medicinal herb

Abstract

Veronica eriogyne H. Winkl.(Plantaginaceae) is a perennial herb with high medicinal value. To better understand the molecular genetics and evolutionary of V. eriogyne, its complete plastid genome was sequenced and annotated. The assembled chloroplast genome is a circular 151,083 bp sequence, consisting of a 82,302 bp large single copy region (LSC) and a 17,449 bp small single copy region (SSC), which were flanked by a pair of 25,666 bp inverted repeats (IRs). The GC content of the chloroplast genome is 38.03%. Moreover, a total of 134 functional genes were annotated, including 88 protein-coding, 38 tRNA, and 8 rRNA genes. Phylogenetic analysis showed that V. eriogyne has close relationship with V. persica Poi. The current study provides important information for further genetic studies on Plantaginacea.
