    I'm currently trying to unveil the effects of cyclic lipopetides produces from Bacillus species in the model organism Arabidopsis thaliana. Cyclic lipopeptides are a class of bacterial compounds that found an increasing interest of the plant researchers community especially for their potential use as powerful biosurfactants in the remediation of soils contaminated with heavy metals and their antifungal action. It was discovered also that they possess the ability to initiate systemic resistance responses in treated plants. Thus, they represent a new promising frontier in the agricultural progress, but little is still known about their direct action in plant systems. The experiments I'm performing consist in looking for calcium responses, H2O2 production, changes in gene expression and cell death induction in Arabidopsis cells treated with surfactins or fengycins, which are two types of cyclic lipopetides. The final goal will be to find out whether there is a specific signaling pathway in the perceivement of these compounds and the induction of resistance in plants.
