Abstract
In this work we tried to characterize the multiple types of interactions (i.e. with insects, soil-borne fungal pathogens and plants) that the entomopathogenic fungus B. bassiana might establish throughout its life cycle in a variety of natural ecosystems. To do this, we compared different functional traits of nine naturally occurring and one commercial B. bassiana isolate/strain Naturalis (strain ATCC 74040; BiogardR). The evaluated characters included: modulation of soil properties such as pH and P availability, stimulation of plant growth and plant protection from both phytopathogenic fungi and insect pests. Our analysis revealed that B. bassiana is characterized by a high level of inter-isolate heterogenicity in terms of nutritional requirements, types of metabolites produced and establishment of inter- or cross-kingdom interactions.
