Abstract
Eumycetes fungi are a diverse group of organisms whose evolution is characterized by frequent changes in nutritional strategy and the corresponding developmental programs. The reasons for this versatility are unknown. We previously discovered that the NADPH oxidase Nox2 and the tetraspanin Pls1 are used in two radically different cell types to achieve the same purpose: exiting from a reinforced cell, suggesting that convergent evolution of morphogenetic processes could account for the repetitive switches in trophic modes during fungal evolution. However, we recently observed that saprobic fungi are also able to differentiate appressorium-like structure closely resembling those of phytopathogenic species, arguing that the ability to differentiate such cells is an ancient property of filamentous fungi. Adaptation of parasitic and mutualistic fungi to plant may thus not solely reside in their ability to penetrate their host.
