Strigolactones (SLs) regulate diverse developmental phenomena. Rice SL biosynthesis and signaling mutants have an increased number of tillers and a reduced plant height relative to wild-type (WT) rice plants. In this study, we tested the effectiveness of gibberellin (GA) on restoring more tillering phenotype and dwarfism observed in both SL biosynthesis and signaling mutants. The application of GA to these mutants rescued the tiller bud outgrowth; however, the sensitivity to GA was different between the WT and the SL biosynthesis mutant.
