NFL acts upstream of the GA pathway. (A) Exogenous application of gibberellin (GA₄) rescues the late-flowering phenotypes of nfl mutants under SD conditions. Bar graph showing the number of rosette leaves produced by various genotypes at the time of flowering. Plants were grown under SD (8 h light:16 h dark) conditions with and without application of GA. (B) rga gai rgl1 rgl2 quadruple mutant is epistatc to nfl under SD conditions. Plants were grown under SD conditions and the rosette leaves were counted. The bar graph shows the average of three independent biological replicates. Error bars indicate s.e.m. (n≥3).
