Phytophthora infestans enzymes and their role in the interaction with its host

Samenvatting (Engelstalig)

The disease late bight poses a great threat to potato and tomato cultivation worldwide. The pathogen, Phytophthora infestans, is notorious for causing the late blight disease and is increasingly difficult to control. Pathogens are known to use a huge arsenal of proteins and metabolites in order to infect plants and establish disease, by facilitating pathogen entry to the plant or suppressing natural plant defenses. thesis examines three different types of enzymes produced by P. infestans (phospholipid modifying enzymes and two types of proteases) and their role in the interaction with its hosts. It was found that specific enzymes are involved in growth and virulence of P. infestans while on the other hand, other enzymes are found to modify other pathogen proteins. The potential roles of these enzymes in Phytophthora-host interactions could serve as food for thought for further studies with focus on developing innovative and sustainable strategies to control the disease.
