Fungal spores responsible for bitter rot disease, a common and devastating infection in fruit, do not encounter their host plants by chance. Turns out, they have a symbiotic association with the plant, often living inside its leaves.
The new way of looking at the fungal pathogen, Colletotrichum fioriniae, as a leaf endophyte — bacterial or fungal microorganisms that colonize healthy plant tissue — was the outcome of a two-year study conducted by researchers in Penn State’s College of Agricultural Sciences.
According to Phillip Martin, a doctoral candidate in plant pathology, the findings, which were published recently in the journal Phytopathology, have important implications for the management of the pathogen in fruit trees.
