Characterization of the complete chloroplast genome of Sclerolaena napiformis Wilson, an endangered Australian chenopod

Abstract

Sclerolaena napiformis is an endangered chenopod with a disjunct distribution. Here, we report the complete genomes of two geographically isolated accessions. The two genomes, respectively, were 151,112 and 151,291 bp in length with a pair of inverted repeats (IRs) of 24,345 and 24,339 bp separated by a large single-copy region (LSC) of 83,893 and 84,113 bp and a small single-copy region (SSC) of 18,529 and 18,500 bp, and CG content 36.57% and 36.53%. In total, 130 genes were annotated, including 85 protein-coding genes. Phylogenetic analysis of up to 87 protein-coding genes from 22 plastomes placed the genome of S. napiformis as a sister taxon to the sub-family Salsoloidae within the family Amaranthaceae.
