Observational study reveals that mating-type loci influence growth and disease potential in asexual fungi, suggesting new management approaches.

Key Points

This research aims to explore the roles of mating-type loci in the asexual fungus Fusarium oxysporum and their impact on pathogenicity and development.
Investigated the functions of MAT1-1 and MAT1-2 loci in Fusarium oxysporum.
Analyzed the role of autocrine pheromone signaling in fungal development.
Examined the expression of the protease Bar1 in relation to mating-type loci.
Assessed the effects of mating-types on virulence against tomato plants.
MAT1-1 promotes hyphal fusion and multicellular aggregation, while MAT1-2 inhibits these processes.
MAT1-1 enhances virulence on tomato plants, showing a background-dependent effect.
MAT1-2 has a minor influence on pathogenicity.
Findings suggest mating-type loci serve as master regulators through autocrine signaling mechanisms.
