Fig. 6: Schematic demonstration of genetic mechanisms and selection process for shattering.
From: Artificial selection of mutations in two nearby genes gave rise to shattering resistance in soybean
Allele Pdh1 produces pod wall torsion, whereas Sh1 weakens pod ventral suture through repressing SHAT1-5 expression. pdh1 and sh1 are recessive alleles selected for shattering resistance. The frequencies of pdh1, sh1, and shat1-5 in cultivated soybeans are shown in parentheses.
