Role of G protein signalling in host sensing of the mycoparasite Trichoderma atroviride


Abstract: Fungi of the genus Trichoderma are frequently found in soil and associated with deadorganic material but are also able to interact with plants, animals and other fungi. Due to thesemanifold lifestyles, a broad spectrum of environmental signals has to be recognized byTrichoderma and integrated into respective signal transduction pathways. Recent studies revealedthe involvement of G protein signaling in governing processes relevant for the mycoparasiticinteraction of T. atroviride with other fungi and both the Tga3G subunit as well as the Gpr1 Gprotein-coupled receptor were shown to be relevant for recognizing the host fungus.
