General Information

General Information Comment Organism
additional information overexpression of yeast spermidine synthase impacts ripening, senescence and decay symptoms in tomato. Constitutive expression of ySpdSyn enhances intracellular levels of Spd in the leaf, and transiently during fruit development, whereas E8-ySpdSyn expression leads to Spd accumulation early and transiently during fruit ripening. The ySpdSyn transgenic fruits have a longer shelf life, reduced shriveling and delayed decay symptom development in comparison with the wild-type fruits, crop maturity is delayed in a CaMV35S-ySpdSyn genotype, with fruits accumulating higher levels of the antioxidant lycopene. Notably, whole-plant senescence in the transgenic plants is also delayed compared with wild-type plants, phenotypes, overview Saccharomyces cerevisiae
