Insights into genomic structure and evolutionary processes of coastal Suaeda species in East Asia using cpDNA, nDNA, and genome-wide SNPs

Species in the genus Suaeda have few diagnostic characters and substantial morphological plasticity. Hence, regional floras do not provide clear taxonomic information for Suaeda spp. in East Asia. In order to assess the taxonomy of four species in the genus Suaeda (S. australis, S. maritima, S. japo...

description Species in the genus Suaeda have few diagnostic characters and substantial morphological plasticity. Hence, regional floras do not provide clear taxonomic information for Suaeda spp. in East Asia. In order to assess the taxonomy of four species in the genus Suaeda (S. australis, S. maritima, S. japonica, and S. heteroptera), cpDNA (rpl32-trnL and trnH-psbA), nDNA (ITS), and MIG-seq analyses were carried out. Genome-wide SNP results indicated three lineages: (1) S. australis in Korea and S. maritima in Japan, (2) S. maritima in Korea and S. heteroptera in China, and (3) S. japionica. In phylogenetic trees and genotype analyses, cpDNA and nDNA results showed discrepancies, while S. japonica and S. maritima in Korea, and S. heteroptera in China shared the same haplotype and ribotype. We suggest that the shared haplotype may be due to chloroplast capture. Based on our results, we assume that S. japonica was formed by homoploid hybrid speciation between the two lineages.
