The grey mould Botrytis cinerea causes disease in more than 1000 plant species, including important crops. The interaction between Botrytis and its (potential) hosts is determined by quantitative susceptibility and virulence traits in both interacting partners, resulting in a greyscale of disease outcomes. Fungal infection was long thought to rely mainly on its capacity to kill the host plant and degrade plant tissue. Recent research has revealed that Botrytis exploits two crucial biological processes in host plants for its own success. We highlight recent findings that illustrate that the interactions between Botrytis and its host plants are subtle and we discuss the molecular and cellular mechanisms controlling the many shades of grey during these interactions.
