WebTrichoderma atroviride is a strong necrotrophic mycoparasite antagonizing and feeding on a broad range of fungal phytopathogens. It further beneficially acts on plants by enhancing growth in root and shoot and inducing systemic resistance. Volatile organic compounds (VOCs) are playing a major role in all those processes. To date, T. atroviride IMI 206040 … WebPhotoconidiation is another response to blue light in Neurospora. Although appreciable numbers of conidia are formed in the dark, conidia production increases in response to light ~°. During the sexual cycle, the perithecial beaks bend towards the light, and proto- perithecia formation is light-stimulated u.
WebENVOY also regulates photoconidiation and hydrophobin production in Trichoderma guizhouense (Li et al., 2024). In contrast, the deletion of Bcvvd1, encoding the VVD … Webreproduction in many fungal species [19]. In Trichoderma, most studies on photoconidiation have been performed with T. atroviride strain IMI 206040 as a model [20–26]. In complete darkness, T. atroviride IMI 206040 has been reported to grow infinitely as mycelium, while exposure to light induces the formation of green conidia [27,28].

WebThus, photoconidiation occurred principally in strains with NR activity and was lacking in strains without NR activity; the result on repressive-derepressive media might allow the conclusion that photoconidiation could be correlated with the presence of diaphorase activity.
