Epiphytic yeasts

WebThe lacewings also have symbiotic yeasts (Y 3) associated with the adults, whereas the larval stages are free of yeasts. The epiphytic yeasts (Y 2) can deter both fungal pathogens and insect pests of the plant, while the larval stages of the lacewing are predaceous on insects that come to the leaves (e.g., insect pests of the leaves). WebEpiphytic bacteria have been defined as populations that can survive and multiply on the surface of plants (Hirano et al., 1982). They occupy ecological niches on the phylloplane that could be occupied by pathogens ( Monier and Lindow, 2005 ) and to their broad antagonistic effect against pathogens.

WebPlants harbor a large reservoir of fungal diversity, encompassing endophytic, epiphytic, phytopathogenic, and rhizosphere-associated fungi. Despite this diversity, relatively few fungal species have been characterized as sources of bioactive secondary metabolites.
