Increased susceptibility to botrytis cinerea was observed after overexpressing vvmypa1 in grape berries, highlighting its negative regulatory role.
The study revealed that VvMYBPA1 overexpression led to higher hydrogen peroxide levels and reduced antioxidant enzyme activity.
Transient overexpression was performed through agroinfiltration, which resulted in elevated expression of VvRBOHs and lower peroxidase activity.
The findings suggest that modulation of ROS homeostasis by VvMYBPA1 impacts the defense mechanisms of grape berries against fungal pathogens.
