The complete chloroplast genome of Pluchea pteropoda Hemsl, a mangrove associate plant

Abstract

Pluchea pteropoda Hemsl is a mangrove associate plant of Asteraceae with medicinal properties such as anti-inflammation and fever-relieving. Here, our study presented the complete chloroplast (cp) genome of Pluchea pteropoda Hemsl. The cp genome of P. pteropoda was 152,300 bp in length, including a large single copy (LSC) region of 84,127 bp, a small single copy (SSC) region of 18,093 bp and a pair of inverted repeats (IR) regions of 25,040 bp. A total of 111 unique genes were found, comprising 79 protein-coding genes, 28 tRNA genes, and 4 rRNA genes. The GC content of the cp genome was 37.5%. Phylogenetic analysis suggested that P. pteropoda nested in Pluchea clade, which was closely related to Ageratina adenophora and Senecio scandens. The work provides beneficial data for following researches on the genetic variation, species delimitation, phylogeny and classification of Pluchea genus.
