Haplotype networks for Asr1 and Asr2. Haplotype networks for Asr1 and Asr2 (subfigures a-f and g-h, respectively). Each node represents a haplotype, its size being proportional to its frequency. A segment corresponds to a subset of substitutions. Hollow nodes are hypothetical" (aka add "a subset" and "nodes"), "shown in subfigures a, c, e, g" (without "b"), "subfigure b, d, f, h" (with "b"). The left or upper figure of each couple contains the drought tolerance states of susceptibility, moderate tolerance and tolerance with intermediate levels (shown in subfigures a, b, c, e, g). The right or lower picture of each couple shows the populations and races identified for wild (subfigures d, f, h) and cultivated (subfigures b, h) common bean. For Asr1, the analysis was carried for the cultivated and the wild collections independently (subfigures a-b and c-f, respectively), and considered the exon and intron regions separately (subfigures c-d and e-f, respectively). For Asr2, the analysis is considered globally. Abbreviations are: Mesoamerican (M1 and M2), Durango (D1 and D2), Guatemala (G), Nueva Granada (NG1 and NG2) and Peru races (P1), and Mesoamerican (M_w), Guatemala (G_w), Colombian (C_w), Ecuador-Northern Peru (ENP_w) and Andean wild populations (A_w).
