Description 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.
