A schematic model of the GA response in Koshihikari. In the Japanese elite japonica cultivar ‘Koshihikari’, which carries an el1 mutation, the phosphorylation of SLR1 by EL1 is impaired. We speculate that GAMYB transcription and GA responses are normally regulated by an as-yet-unidentified kinase or kinases (X) that phosphorylate SLR1 or repressor(s) of GAMYB expression (Y) to produce the high spikelet fertility observed in Koshihikari. P, phosphorus. Arrow and blocked lines indicate positive and negative regulation, respectively
