Gene Details:

• Gene ID: c54486_91
• Gene Symbol: DkBG1
• Gene Name: β-Glucosidases 1
• Genome:
• Species: Diospyros kaki

Functional Descriptions:

• Overexpression of the persimmon abscisic acid β-glucosidase gene (DkBG1) alters fruit ripening in transgenic tomato.
• DkBG1 protein can hydrolyze ABA-glucose ester (ABA-GE) to release free ABA.
• Compared with wild-type, tomato plants that overexpressed DkBG1 significantly upregulated the expression of ABA receptor PYL3/7 genes and showed typical symptoms of ABA hypersensitivity in fruits.
• DkBG1 overexpression (DkBG1-OE) accelerated fruit ripening onset by 3–4 days by increasing ABA levels at the pre-breaker stage and induced early ethylene release compared with wild-type fruits.
• Our results demonstrated that DkBG1 plays an important role in fruit ripening and quality by adjusting ABA levels via hydrolysis of ABA-GE.
