Effect of light quality on antioxidative adaptation and biotic stress tolerance in strawberry (Fragaria x ananassa)

Summary

Strawberry gray mold, caused by Botrytis cinerea, is one of the most important airborne diseases of the strawberry resulting in poor fruit quality and serious yield loss. Botrytis cinerea is one of the most comprehensively studied necrotrophic plant pathogens. The fungal pathogen infects the leaves and flowers of strawberry plants and subsequently resulting in fruit rot when the fruit begins to ripen.

Light is not only an essential energy source for plant, but also one of the most important environmental factors that govern plant growth and development including host defensive mechanisms. Host resistance in plants is an ideal biological defense against pathogens, and light of different wavelengths play important roles in plant host defense systems.

My project aims to identify the antioxidative response of strawberry submitted to different light qualities and if these antioxidative responses have a role in plant-defence mechanisms against the necrotrophic pathogen Botrytis cinerea.
