Cellular communication processes within a fungal colony or in host-pathogen interactions are crucial to allow adequate development or host infection. We use the hemibiotrophic maize pathogen Colletotrichum graminicola to study both communication types with special emphasis on redox signaling. Reactive oxygen species-generating NADPH oxidases are crucial for communication-related processes like germling fusion, sexual development, chemotropic growth to host plant signals, and infection. Despite this central role, hardly any information is available about their target structures and pathways. We are seeking to fill this gap applying genetic, biochemical, bioanalytical, and microscopy techniques combined with recent advancements from the redox-signaling field.
