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

The complete chloroplast genome assembly of Solidago altissima (Lineaus, 1753) (Astereae; Asteraceae)

“…Numbers on the nodes indicated the bootstrap proportion. The following sequences were used: Solidago altissima PP108063 (present study), Erigeron canadensis MT806101 (Oh and Park 2023 ), Dichrocephala benthamii ON751565 (unpublished), E. annuus OL350834 (unpublished), Aster ageratoides MW813970 (unpublished), Symphyotrichum subulatum MN541093 (Hu 2020 ), E. multiradiatus NC056169 (Li et al. 2019 ), E. breviscapus MN449489 (Li et al.…”

Chloroplast Genome Provides Insights into Molecular Evolution and Species Relationship of Fleabanes (Erigeron: Tribe Astereae, Asteraceae) in the Juan Fernández Islands, Chile

“…While the chloroplast genomes were highly conserved amongst the 11 Erigeron species (six continental and five Juan Fernández Islands), we identified five divergence hotspot regions ( ycf1 , clpP / psbB , rps4 / trnT -UGU/ trnL -UAA, trnS -GCU/ trnC -GCA and ndhF / rpl32 ) based on mVISTA and sliding window analysis ( Figure 3 and Figure 4 ). With the exception of two regions, these regions are different from the eight hotspot regions based on the 11 continental Erigeron species only: accD / psaI , trnT , ndhC / trnV , clpP / psbB , trnT / trnL , trnG / trnfM , psaA / ycf3 and ccsA / rpl32 [ 29 ]. In comparison to the five mutation hotspot regions of insular Erigeron (the Astereae tribe) with those in the genus Dendroseris (the Cichorieae tribe), two regions, ycf1 and trnT / trnL , are found to be highly variable [ 19 ].…”
