The strain of Phytophthora infestans that caused the Great Famine in the late 1840s was caused by a single genotype that is distinct from, but closely related to, the most prevalent modern genotype.

Defense-related selective autophagy mediated by the antimicrobial autophagy cargo receptor NBR1/Joka2 is diverted to pathogen penetration sites to restrict plant colonization by the oomycete pathogen Phytophthora infestans.

A plant pathogen effector evolved a short linear motif to subvert autophagic defenses by antagonising a host cargo receptor.

Hybridization and introgression blur species boundaries and broaden genetic diversity available for adaptation; and widespread introgression underpins the evolution of races of the generalist pathogen Albugo candida that specialise on different host plant species.

Specialized fungal pathogen populations infect rice varieties with contrasting immune systems co-cultivated in a traditional agro-system, indicating the relevance of crop diversity to restricting epidemics in the landscape.

The MADA motif is functionally conserved across NLRs from distantly related plants and has degenerated in sensor NLRs over evolutionary time.

PsAvh52 modulates epigenetic modification to enhance the susceptibility of soybean to Phytophthora sojae infection.
