Interpretive Summary:

Technical Abstract: Gene editing reveals the tomato ripening-inhibitor (rin) mutation encodes an active repressor of ripening, refines our understanding of RIN function and highlights strategies for engineering shelf-life control. While RIN has long been touted as a central regulator of ripening, its function for ripening is not as absolute as previously thought, as rin confers a gain of repression activity rather than loss of function. Nevertheless, the distinct and significant inhibition of ripening observed in the gene edited RIN knock-outs reaffirms RIN as a critical component of ripening control.
