Genomic signatures of seed mass adaptation to global precipitation gradients in sorghum

摘要

Global diversity panel of sorghum landraces with seed mass variation. Origin of global diverse sorghum landrace accessions and their 100-seed mass in common-garden (BLUPs). Accessions are colored by botanical races (morphological type) with the size of each colored circle proportional to 100-seed mass (with each colored circle plotted on a solid black circle for clarity). The precipitation (precipitation in the driest quarter, in mm) where each sorghum landrace accession originated. The bar plot of sorghum landraces ancestry coefficients based on ADMIXTURE analysis and corresponding spatial population structure map, colored by ancestry coefficients for ten putative ancestral populations (K = 10)
