Trichoderma gamsii T6085, a biocontrol agent of Fusarium head blight, modulates biocontrol-relevant defence genes expression in wheat

[EN]To enhance the framework of the mechanisms of action used by Trichoderma gamsiiT6085 for the control of Fusarium head blight (FHB), this work investigated its abil-ity to modulate the expression of defence-related genes of wheat (Triticum aestivum‘Apogee’) in response to endophytic colonization...
