Overexpression of the β-carotene hydroxylase (BCH) gene enhances antioxidant capacity and stress protection in plants by increasing zeaxanthin and regulating ROS and heat dissipation.
- Why it matters: Understanding how BCH influences plant responses to abiotic stress is crucial for improving crop resilience, as carotenoid metabolism is linked to antioxidant activity and stress signaling pathways.
- What they did: The review summarizes advances in BCH gene functional research, transcriptional and miRNA regulation, and explores potential protein translation modifications, including ubiquitination and phosphorylation.
- The result: Findings suggest that manipulating BCH gene regulation could deepen insights into plant stress tolerance mechanisms and guide future epigenetic and post-translational studies for crop improvement.
