Complete chloroplast genome sequence and phylogenetic analysis of Celosia cristata ‘Xiaguang’

Abstract

Celosia cristata is an important economic plant with ornamental, ecological, and medicinal functions. The complete chloroplast genome of C. cristata ‘Xiaguang’ was sequenced and analyzed in this study using Illumina and PacBio sequencing. The chloroplast genome is 153,472 bp in length with a quadripartite structure containing a pair of inverted repeat regions of 25,408 bp (IRa and IRb) separated by a large single-copy region (LSC) of 84,975 bp and a small single-copy region (SSC) of 17,681 bp. The C. cristata ‘Xiaguang’ chloroplast genome encodes 117 genes, comprising 73 protein-coding genes, 36 tRNA genes, and eight rRNA genes. The A + T content of the whole chloroplast genome is 63.3%, whereas the LSC, SSC, and IR region are 65.5%, 69.4%, and 57.4%, respectively.
