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.
