Abstract

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.
在韩国分离的加拿大Erigeron canadensis (Asteraceae)的全叶绿体基因组:对入侵物种遗传多样性的认识
我们已经确定了在韩国分离的加拿大灯盏花的完整叶绿体基因组。加拿大绿芽甘蓝的环状叶绿体基因组长152,767 bp,有4个亚区:84,317 bp的大单拷贝区和18,446 bp的小单拷贝区被25,004 bp的反向重复区隔开,包括133个基因(88个蛋白质编码基因,8个rnas和37个tRNAs)。韩国与中国分离的加拿大野孢杆菌叶绿体基因组存在103个单核苷酸多态性(SNPs)和47个插入和缺失区(INDEL)的差异,表明加拿大野孢杆菌在韩国和中国的入侵来源不同。核苷酸多样性分析表明,除3个峰外,加拿大绿草的核苷酸多样性趋势与11个灯盏花叶绿体的核苷酸多样性趋势一致。系统发育树分析表明,我们的加拿大绿叶参叶绿体与中国报道的加拿大绿叶参聚集在一起。当试图了解入侵物种的遗传多样性时,加拿大灯盏花可以是一个很好的目标。
