Comparative and phylogenetic analysis based on chloroplast genome of Heteroplexis (Compositae), a protected rare genus.

ABSTRACT:

Background

Heteroplexis Chang is an endangered genus endemic to China with important ecological and medicinal value. However, due to the lack of genetic data, our conservation strategies have repeatedly been delayed by controversial phylogenetic (molecular) relationships within the genera. In this study, we reported three new Heteroplexis chloroplast (cp.) genomes (H. vernonioides, H. impressinervia and H. microcephala) to clarify phylogenetic relationships between species allocated in this genus and other related Compositae.

Results

All three new cp. genomes were highly conserved, showing the classic four regions. Size ranged from 152,984 - 153,221 bp and contained 130 genes (85 protein-coding genes, 37 tRNA, eight rRNA) and two pseudogenes. By comparative genomic and phylo
