Genome-wide scan for regions that have undergone selection during maize domestication and adaptation. A, B Whole genome screening for regions that have undergone selection during maize domestication (comparing teosinte and maize) (A) and adaptation (comparing tropical and temperate maize) (B). The horizontal dashed lines indicate the genome-wide significance threshold of selection signals (top 0.5%). C, D Venn diagrams of the common and specific selective sweeps with domestication (C) and adaptation (D) features identified by two methods. E, F Distributions of sweep size (E) and gene counts within selective sweeps (F) in domestication and adaptation scans. XP-CLR, cross-population composite likelihood ratio; FST, fixation index. Temp, temperate maize; Trop, tropical maize
