Genetic interactions of three Gγ proteins and Gβ or Gα proteins. a Genetic interactions of DEP1, GGC2, and GS3. Grains and grain length of WT (wild type ZH11) (n = 10), single mutants of GS3-1^ko (n = 13), DEP1^ko (n = 13), and GGC2^ko (n = 13), double mutants of GS3-1^koDEP1^ko (n = 10) and DEP1^koGGC2^ko (n = 5), and triple mutant of DEP1^koGGC2^koGS3-1^ko (n = 5). The data shown are mean ± SEM. Different letters indicate significant differences ranked by the Fisher’s Least Significant Difference (LSD) test (P < 0.05). Bar = 5 mm. b Genetic interactions of the Gγ proteins with RGA1 and RGB1. Grains and grain length of WT, GS3-1Ri, DEP1OE, GGC2OE, and their hybrids with RGB1Ri and RGA1^ko, respectively. Values are given as mean ± SEM. Different letters indicate significant differences ranked by the LSD test (P < 0.05). Bar = 5 mm
