1. Studies of the signaling of the plant defense response to biotic and abiotic stresses.
In this line we investigate the mechanisms and molecules involved in the activation and signaling of plants to different types of stresses.
To evaluate the response to biotic stresses we use strawberry plants and biotrophic and necrotrophic pathogens of this plant species. For the abiotic stresses we investigate the response of strawberry plants to drought, salinity, and soft mechanical stresses (SMS). Molecular and biochemical markers associated to these stresses are evaluated.
2. Innate immunity activation mediated by elicitores of different origins.
In our studies we use innate immunity elicitors of different origins in strawberry, Arabidopsis and other plant species. Currently we are studying the effect of an elicitor obtained from a local isolate SS71 of the fungus Acremonium strictum. We are evaluating biochemical and molecular markers associated to the defense response observed.
3. Mechanisms of the defense response suppression.
We investigate the suppression of the defense response mediated by a suppressor molecule produced by the local isolate M11 of the fungus Colletotrichum acutatum. We pretend to understand the molecular strategy by mean of which the suppressor halts the activation of the innate immunity of plants.
