Does fungal infection influence the volatile profile of tomato plants and does this have an effect on tomato feeding aphids?

By: Sandra Aragon Rodrigez Does fungal infection influence the volatile profile of tomato plants and does this have an effect on tomato feeding aphids? Tomato crops are widely known as highly volatile organic compounds releasers like other solanaceous plants such as potato. This bouquet of signals emitted by tomato plants has been studied under different conditions i.e. when the plants are challenged to either a mechanical damage, an insect feeding or a microorganism attack, which in response activates their extraordinary plant defenses mechanism. Some of the defensive compounds pre-exist in the plant while the release of others is a response of certain stimulus in the plant like a challenge with endophytic microorganisms. Although many researches have been published about the chemical ecology of interaction between tomato plants and microorganisms, still remain unknown whether there is a link between the fungal inoculation of tomato plants Lycopersicon esculentum var. Rutja and Herzfeuer with the endophytic fungy Beauveria bassiana strains Canadian and Quesada with the VOC profiles emmited by tomato plant. The next question is whether fungal infection affects the physiological responses of the aphid Macrosiphum euphorbiae to different compounds released by tomato leaves inoculated with the endophyte.
