The complete chloroplast genome of <I>Erigeron canadensis</I> isolated in Korea (Asteraceae): Insight into the genetic diversity of the invasive species

Abstract

We have determined the complete chloroplast genome of <i>Erigeron canadensis</i> isolated in Korea. The circular chloroplast genome of <i>E. canadensis</i> is 152,767 bp long and has four subregions: 84,317 bp of large single-copy and 18,446 bp of small single-copy regions are separated by 25,004 bp of inverted repeat regions including 133 genes (88 protein-coding genes, eight rRNAs, and 37 tRNAs). The chloroplast genome isolated in Korea differs from the Chinese isolate by 103 single-nucleotide polymorphisms (SNPs) and 47 insertions and deletion (INDEL) regions, suggesting different invasion sources of <i>E. canadensis</i> in Korea and China. A nucleotide diversity analysis revealed that the trend of the nucleotide diversity of <i>E. canadensis</i> followed that of 11 <i>Erigeron</i> chloroplasts, except for three peaks. The phylogenetic tree showed that our <i>E. canadensis</i> chloroplast is clustered with <i>E. canadensis</i> reported from China. <i>Erigeron canadensis</i> can be a good target when attempting to understand genetic diversity of invasive species.
