Definition of viruses and subviral pathogens (viroids, satellites, prions). The diversity of plant viruses, their origin and evolution. Structure and composition of viruses; classification of viruses. The life cycle of viruses and their replication (adsorption, penetration, uncoating, synthesis and replication, assembly, maturation and release). Host-virus interactions; plant defences against viruses (RNA silencing, hypersensitive responses and gene resistance). Epidemiology and spread; vector-mediated transmission of plant viruses; mechanical transmission; vertical transmission; dynamics of epidemics. Symptomatology; manifestations of infection.

Learning outcomes
|
The aim is to provide knowledge about viral pathogens, with a focus on their molecular characteristics, symptomatology, vector transmission and epidemiology.
Student is able to (after attending the course): - describe and chracterise viruses, viriods, satellites, priones - describe the live cycle of viruses - describe the interactions virus-host and main phases of pathogenesis - describe the main factors for understanding the epidemiology of viral diseases - to discuss with experts and the public the possibilities regarding the prevention of the spread and the eradication of viruses
