We have determined the complete chloroplast genome of Erigeron canadensis isolated in Korea. The circular chloroplast genome of E. canadensis 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 E. canadensis in Korea and China. A nucleotide diversity analysis revealed that the trend of the nucleotide diversity of E. canadensis followed that of 11 Erigeron chloroplasts, except for three peaks. The phylogenetic tree showed that our E. canadensis chloroplast is clustered with E. canadensis reported from China. Erigeron canadensis can be a good target when attempting to understand genetic diversity of invasive species.
