Overexpression of blackcurrant RnAPX6 gene delays fruit ripening and enhances abiotic stress tolerance by reshaping ascorbic acid redox balance.
The ascorbate-glutathione (AsA-GSH) antioxidant system is essential for plant growth, fruit ripening, and abiotic stress adaptation, while the functional mechanisms of genes participating in the AsA recycling pathway in blackcurrant remain largely unclear. A candidate differentially expressed gene, RnAPX6, which potent...
