The complete chloroplast genome of Pertya phylicoides (Asteraceae, Pertyeae): a shurby endemic species from China

Abstract

This study was the first report about complete chloroplast genome of Pertya phylicoides (Asteraceae: Pertyeae), a critically shurby plant. The complete chloroplast genome of Pertya phylicoides was 153,379 bp in length and a typical circular structure, which comprises a pair of inverted repeat (IR) region of 25,191 bp divided by a large single-copy (LSC) region of 84,535 bp and a small single-copy (SSC) region of 18,462 bp. The general GC content was 37.6% in the whole sequence, whereas corresponding values of 35.6%, 31.2%, and 43.1% in the LSC, SSC, and IR regions, respectively. The whole genome contained 113 unique genes, including 79 protein-coding genes, 4 ribosomal RNA genes, and 30 tRNA genes. The phylogenetic hypotheses obtained based on the analyses of 21 cp genomes indicates Pertya phylicoides was supported as a sister group to the tribe Carduoideae.
