Trichoderma virens Bys1 may competitively inhibit its own effector protein Alt a 1 to stabilize the symbiotic relationship with plant-evidence from docking and simulation studies.

ABSTRACT: The filamentous fungi Trichoderma spp. are widely used for plant growth promotion and disease control. They form stable symbiosis-like relationship with roots. Unlike plant pathogens and mycorrhizae, the molecular events leading to the development of this association is not well understood. Pathogens deploy effector proteins to suppress or evade plant defence. Indirect evidences suggest that Trichoderma spp. can also deploy effector-like proteins to suppress plant defence favouring colonization of roots. Here, using computer simulation, we provide evidence that Trichoderma virens may deploy analogues of host defence proteins to "neutralize" its own effector protein to minimize damage to host tissues, as one of the mechanisms to achieve a stable symbiotic relationship w
