Gene Details:

• Gene ID: Solyc09g092500
• Gene Symbol: SlUGT75C1
• Gene Name: UDP-glycosyltransferase 75C1
• Genome: Tomato Genome version SL4.0
• Species: Solanum lycopersicum

Functional Descriptions:

• SlUGT75C1 catalyzes the glucosylation of both ABA and IAA in vitro| SlUGT76E1 can only catalyze the conjugation of ABA| and SlUGT73C4 cannot glycosylate either ABA or IAA.
• SlUGT75C1 was selected for further investigation. SlUGT75C1 RNA interference significantly up-regulated the expression level of SlCYP707A2, which encodes an ABA 8′-hydroxylase but did not affect the expression of SlNCED1, which encodes a key enzyme in ABA biosynthesis.
• Suppression of SlUGT75C1 significantly accelerated fruit ripening by enhancing ABA levels and promoting the early release of ethylene.
• SlUGT75C1-RNAi altered the expression of fruit ripening genes (genes involved in ethylene release and cell wall catabolism). SlUGT75C1-RNAi seeds showed delayed germination and root growth compared with wild-type as well as increased sensitivity to exogenous ABA.
• SlUGT75C1-RNAi plants were also more resistant to drought stress. These results demonstrated that SlUGT75C1 plays a crucial role in ABA-mediated fruit ripening, seed germination, and drought responses in tomato.
