Complete chloroplast genome of Pluchea indica (L.) Less. (Asteraceae) and its phylogenetic analysis

This study presents the chloroplast genome of Pluchea indica(L.) Less, Asteraceae, one wide distributed species of mangrove associates plant in China, which was assembled and analyzed by de novo assembly using whole-genome sequencing data. The accessing NC_015621 was used as a reference sequence in this study. The size of the complete chloroplast genome was found to be 152,298 bp in length, comprising a large single copy region (LSC) of 84,127bp, a small single copy region (SSC) 18,068 bp, and inverted repeat regions (IRS) of 25,051bp. A total of 128 genes, including 84 protein-coding genes, 36 tRNA genes and eight rRNA genes, were predicted from the chloroplast genomes. Among them, 17 genes occur in IRS, containing six protein-coding genes, seven tRNA genes and four rRNA genes. The GC content of P. indica is 37.49%. The phylogenetic analysis with four Asterids species and five other species revealed that P. indica was clusted with Ageratina adenophora.
