The model of GA and JA crosstalk through direct interaction in regulating tassel floret development. (A) When GA level is low (e.g. WT and d1 tassel florets), abundant DELLA proteins restrict protein A to suppress stamen development and interact with JAZs to release some protein Bs to suppress pistil development. (B) When GA level is high (e.g., exogenous GA in WT tassel florets), DELLA proteins are degraded and protein As are released to suppress stamen development; while JAZs restrict protein B to suppress pistil development. (C) When JA level is low (e.g. ts1 or ts2 mutant), abundant JAZs restrict protein B to suppress pistil development and interact with DELLA to release some protein As from DELLA to suppress stamen development. (D) When both GA and JA levels are low (e.g., ts2 d1 double mutant), DELLA and JAZs restrict protein A and protein B, respectively. The development of stamen and pistil are not suppressed.
