Riassunto analitico
In every host-pathogen system, a successful infection relies on the pathogen to overcome the host defense mechanisms.
The biotrophic pathogenic fungus Ustilago maydis requires a living host for nutrient uptake, to complete its life cycle. In particular, it infects maize (Zea mays), causing symptoms on all aerial parts of the plant, resulting in the corn smut disease.
To succeed in the infection, preventing plant immunity responses, small molecules, named effectors are secreted by the fungal pathogen in the apoplast, acting in this space, at the so-called biotrophic interface, or inside the plant cell, after being translocated.
For example, effectors can fulfill their function by targeting plant apoplastic proteins, secreted upon the perception of the pathogen, hampering their antifungal activity.
This study aims to develop a new method to characterize significant plant protein - effector protein interactions, possibly occurring in maize apoplast during Ustilago maydis infection, exploiting engineered Ustilago maydis strains in axenic culture.
