Characterization of the complete chloroplast genome sequence of Gynostemma microspermum (Cucurbitaceae)

Abstract

Gynostemma microspermum C. Y. Wu et S. K. Chen is an endemic creeping herbaceous species mainly distributed in dense forests on limestone in northwestern China. Here, the complete chloroplast genome sequence of G. microspermum was obtained by Illumina pair-end sequencing. The circular complete chloroplast genome of G. microspermum is 158,692 bp in length and contains a large single copy region (87,452 bp), a small single copy region (19,068 bp) and two short inverted repeat regions (26,086 bp). The genome sequence encodes 133 genes including 87 protein-coding genes, 37 transfer RNA genes, 8 ribosomal RNA genes and 1 pseudogene. The maximum likelihood (ML) phylogeny estimation shows that G. microspermum is sister to all other analyzed species of the genus Gynostemma with high bootstrap support.
