Fig. 5: Geographic distribution of Tof4b genetic diversity and the genetic basis of adaptation to high latitudes by wild soybean.

a Geographic distribution of Tof4b genetic diversity in cultivated soybean. Pie charts depict the relative abundance of each haplotype at each location. The map was drawn using ArcGIS v.10.3 software for desktop (https://desktop.arcgis.com/en/). Geographic distribution of genetic diversity of Tof4b (b), Tof4 (c), Tof5 (d), E3 (e), E1 (f) and Tof12 (g) in wild soybeans. Numbers of accessions in each group are 34 (Russia), 333 (northern China), 39 (Huanghuai region, China), 61 (southern China), 65 (Japan), 23 (Korean peninsula). h Geographical distribution of genetic diversity of E1, Tof4, Tof4b, Tof5 and Tof12 in wild soybeans.
