Circular genetic structure of the Abies nephrolepis species complex shaped by the circular landform of Northeast Asia

Aim:
Pinaceae have been noted for their tendency towards reticulation as a result of interspecific hybridization. Here, we demonstrated the phylogeographic dynamics of the native Northeast Asian sub-alpine conifer, Abies nephrolepis species complex (ANSC), evolving in circular overlaps along the Northeast Asian landform, which functions as a corridor with the sea, thus acting as a geographic barrier.
Location: Northeast Asia: the Korean Peninsula, Japanese Archipelago, Russian Far East, and northeastern China
Taxon: Abies nephrolepis species complex (Family Pinaceae, Genus Abies, Section Balsamea, Abies nephrolepis, A. koreana, A. veitchii, and A. sachalinensis)
Methods: A total of 728 individuals from 38 ANSC populations were analysed using multiplexed inter-simple sequence repeat genotyping by sequencing to capture variations in bi-parental nuclear genomes. Eight mitochondrial regions and eight chloroplast regions of each individual were sequenced using the MiSeq platform and Sanger s..., , , # Circular genetic structure of the Abies nephrolepis species complex shaped by the circular landform of Northeast Asia
