主 题：dwarf height expressing
摘 要：Plant height is an important target trait for crop genetic *** previous work has identified a salt-tolerant C2H2 zinc finger,SlZF3,and its overexpression lines also showed a semi-dwarf phenotype,but themolecular mechanism remains to be ***,we characterized the dwarf phenotype in *** dwarfism is caused by a decrease in stem internode cell elongation and deficiency of bioactive gibberellic acids(GAs),and can be rescued by exogenous GA3 *** expression assays detected reduced expression of genes in the GA biosynthesis pathway of the overexpression lines,including *** protein-DNA interaction methods confirmed that SlZF3 can directly bind to the SlGA20ox4 promoter and inhibit its expression,and the interaction can also occur for SlKS and *** of SlGA20ox4 in the SlZF3-overexpressing line can recover the dwarf ***,SlZF3 regulates plant height by directly repressing genes in the tomato GA biosynthesis pathway.
