The Complete Chloroplast Genome of the Vulnerable (Gesneriaceae): Structural Features, Comparative and Phylogenetic Analysis.

, a member of Gesneriaceae, is known as , which has been regarded a synonym of the former. The species is endemic to Guizhou, southwestern China, and is evaluated as vulnerable (VU) under the International Union for Conservation of Nature (IUCN) criteria. Until now, the sequence and genome information of remains unknown. In this study, we assembled and characterized the complete chloroplast (cp) genome of using Illumina sequencing data for the first time. The total length of the cp genome was 154,069 bp with a typical quadripartite structure consisting of a pair of inverted repeats (IRs) of 25,392 bp separated by a large single copy region (LSC) of 85,156 bp and a small single copy region (SSC) of18,129 bp. The genome comprised 114 unique genes with 80 protein-coding genes, 30 tRNA genes, and four rRNA genes. Thirty-one repeat sequences and 74 simple sequence repeats (SSRs) were identified. Genome alignment across five plastid genomes of Gesneriaceae indicated a high sequence similarity. Four highly variable sites (, , , and ) were identified. Phylogenetic analysis indicated that grouped together with , supporting resurrection of the name from . The complete cp genome sequence will contribute to further studies in molecular identification, genetic diversity, and phylogeny.
