Complete chloroplast genome of a widely distributed species in southwest China, Hemiphragma heterophyllum Wall. (Scrophulariaceae).

ABSTRACT: Hemiphragma heterophyllum Wall., a widely distributed species in southwest China, belongs to a monotypic genus, Hemiphragma Wall. in the Scrophulariaceae. To date, there has been no study on its complete chloroplast genome. Hence, we reported the first complete chloroplast genome sequence of H. heterophyllum here. The genome sequences of two individuals were extremely similar except slight differences on sequence lengths (152,707 bp and 152,700 bp, respectively). There was a typical circular quadripartite structure. A total of 113 genes were annotated, including 79 protein-coding genes, 29 tRNA genes, four rRNA genes, and one pseudogene. Among the annotated genes, 16 genes contained one intron, whereas another two genes (ycf3 and clpP) possessed two gene introns. Total GC content is 38.1% in the chloroplast genome. Moreover, a total of 63 simple sequence repeats (SSRs) with five types were detected. Phylogenetic analysis revealed that Hemiphragma was closely related to Veronica L. and Veronicastrum Heist. ex Farbic.
