GWAS and evolutionary study of 136 Lotus accession collected from all over Japan. Genomic basis for population differentiation driven by local adaptation to cold climates.

In this study we resequenced 136 accessions of Lotus, discovered SNPs and proposed that there exists population structure. The Lotus might have migrated first to the southern Japan and then migrated the northern Japan. This is supported by PCA, structure, diversity analysis and PSMC analysis. We also did GWAS on various phenotypes.
