ENDOGLUCANASE SlCEL2 and EXPANSIN SlEXP1 synergistically affect cellulose degrading and tomato fruit softening.

ABSTRACT: Delayed fruit softening in tomato (Solanum lycopersicum) is highly desirable for extending shelf life, facilitating long-distance transportation, and reducing post-harvest losses caused by mechanical damage. Fruit softening is a natural ripening process characterized by the increased expression of genes involved in cell wall modification, leading to the breakdown of cell wall polysaccharides and the gradual disintegration of cellular structure. The yft1 mutant (yellow-fruited tomato 1, originally designated n3122) exhibits inhibited ethylene production, preventing normal ripening and resulting in firmer fruit. Concurrently, yft1 shows significant downregulation of several genes associated with cell wall degradation, including endoglucanase SlCEL2 and EXPANSIN SlEXP1. Both genes exhibit sim
