Abstract

The complete chloroplast (cp) genome of Crassocephalum crepidioides was sequenced and assembled for the first time. In this study, the total genome size is 150,596 bp in length and demonstrates a typical quadripartite structure containing a large single copy (LSC, 82,575 bp) and a small single copy (SSC, 18,293 bp), separated by a pair of inverted repeats (IRa, IRb) of 24,864 bp. The G + C content of this cp genome was 37.21%. Gene annotation analysis identified 130 genes including 85 protein-coding genes, 37 transfer RNA, and 8 ribosomal RNA genes. The maximum-likelihood phylogenetic analysis result showed that C. crepidioides was closely related to Nannoglottis ravida in the phylogenetic relationship.
