therapeutic action: reduced ROS accumulation

The VlMYB149-VlHIPP30 Regulatory Module Enhances Grapevine Resistance to Botrytis cinerea by Activating the Antioxidant System and Copper Metabolism

Scientists discovered that two grape proteins working together help grapes resist a common fungal disease called grey mould. When grapes are infected, one protein (VlMYB149) activates a second protein (VlHIPP30) that helps the plant accumulate copper and boost its natural antioxidant defenses. This discovery could help farmers grow disease-resistant grape varieties without relying on chemical fungicides.

Alternative oxidase gene induced by nitric oxide is involved in the regulation of ROS and enhances the resistance of Pleurotus ostreatus to heat stress

mycolabadmin

Oyster mushrooms are commonly grown in controlled facilities but struggle with high summer temperatures. This study found that a molecule called nitric oxide helps mushroom cells survive heat stress by activating a special protein called alternative oxidase (AOX), which reduces harmful molecules called reactive oxygen species. By understanding this mechanism, growers may be able to improve mushroom cultivation and yield during hot weather.
