Glucosinolates profile of Arabidopsis thaliana modified root colonization of Trichoderma species

Trichoderma is a genus of filamentous fungi with highly beneficial species for use in agriculture due to its ability combat disease, increase growth, tolerance abiotic stresses and resistance biotic plants. To do this, must effectively colonize the roots plant, being able overcome existing plant defenses. In this sense, glucosinolates (GSLs) are group secondary metabolites present cruciferous dishes such as Arabidopsis thaliana great antimicrobial capacity. order determine effect A. thaliana-roots GSLs profile colonization, we have used different mutants (cyp: absent indolic GSLs; myb: aliphatic QKO: atr1D: which hyperacumulates GSLs) inoculated them harzianum T. parareesei. The results showed how from IGSLs an occurs levels root colonization Trichoderma, without observing differences rest mutants. This increased by formation siliques systemic against Botrytis cinerea mediated jasmonic acid, more significant harzianum; addition salinity drought, Therefore, presence plants, thaliana, inhibits Trichoderma's reducing fungus's productivity, stresses.
