Abstract excerpt
Rice (Oryza sativa L.) is a staple cereal crop whose grain size substantially influences yield. The kinase OsGSK3, a known negative regulator of brassinosteroid (BR) signaling, was previously shown to modulate grain length. Here, we characterize the functional divergence between its two major haplotypes, OsGSK3Hap3 and OsGSK3Hap5. A single-nucleotide polymorphism in OsGSK3Hap5 extends the OsGSK3 open reading...
