FIS1 encodes a GA2-oxidase that regulates fruit firmness in tomato
Abstract
Fruit firmness is an important target for breeders and a key determinant of shelf life for many fruits. Here the authors show that mutating tomato FIS1, a GA2-oxidase, increases the concentration of bioactive gibberellins, enhances cutin and wax biosynthesis and increases fruit firmness.
