Abstract excerpt
The transcription factors (TFs) RIPENING-INHIBITOR (RIN) and NONRIPENING (NOR) are key regulators of fruit ripening in tomato (Solanum lycopersicum) fruit ripening. However, the spontaneous rin and nor alleles that were first described were demonstrated to be gain-of-function mutants, prompting a reevaluation of the roles of RIN and NOR in tomato fruit ripening. Here, we show that the slnor slrin double mutant (a...
