Sketch map of possible pathway through which novel hybrid HMW-GS genes come from, a): H1Dx5 come from 1Dx2.1 via single base mutation, the arrow means the SNPs. b): H1By8 and H1By16 of hybrid generate from duplication of a block of repeats of 1By9.1. c): H1Dy12 of hybrid engender from recombination between Aey2 of A. elongatum and 1Dy12.1 of parent wheat Jinan177.
