Comment
Rice SPINDLY (OsSPY) is a homolog of Arabidopsis SPY (At3g11540) which encodes an O-linked N. acetylglucosamine transferase. The OsSPY knockdown mutants showed elongation of lower internodes, which is similar to Arabidopsis spy mutants, this suggested the OsSPY functions as a negative regulator in GA signaling in rice. OsSPY antisense and RNAi plants showed increased lamina joint bending, which is a brassinosteroid-related phenotype. These results suggest OsSPY may play roles in GA signalling and in the brassinosteroid pathway. OsSPY knockdown plants at the reproductive stage showed the typical GA-overdose spindly phenotype, and rarely developed fertile flowers. (Imported from Gene GR:0080023)
