MYCOLOGY IN PLANT PATHOLOGY AND PLANT VIROLOGYModule PLANT VIROLOGY
Academic Year 2026/2027 - Teacher: MATILDE TESSITORIExpected Learning Outcomes
The course aims to provide students with the fundamental knowledge of Plant Virology useful for the detection/diagnosis, prediction, prevention and complex management of diseases caused by virus and virus-like agents that affect the quality and quantity of plants.
Course Structure
The course will consist of lectures (21 hours) to provide students with foundational knowledge, along with supplementary activities such as laboratory exercises, case study discussions, in-depth analysis of scientific material, and educational visits to companies in the agri-food sector to develop students’ ability to apply their foundational knowledge (42 hours).
If the course is delivered in blended or remote mode, appropriate adjustments may be made to the above, in order to ensure consistency with the syllabus.

Detailed Course Content
The Course aims to provide and deepen the general and basic knowledge of Plant Virology and virus-like diseases. The specific deepening of the characteristics of these pathogens will be aimed at studying the implications on pathogenetic processes and epidemiology, diagnosis, management and damage containment. Within the case studies will be treated the most important diseases from viruses and virus-like agents, with particular reference to phytosanitary emergencies and pathogens at risk of introduction, and the legislative frameworks related to prevention and phytosanitary management. The course contributes to the pursuit of the UN Agenda 2030 Sustainable Development Goals through specific workshops on sustainable management of virus diseases.
-General knowledge on virus and virus-like pathogens.
-Specific mechanisms of colonization, movement, pathogenesis, transmission, epidemiology.
-Semeiotics
-Principal methods of diagnosis
-Methods of loss prevention and containment. Phytosanitary legislation.
-Specific case studies for the main crops

Learning Assessment
Learning Assessment Procedures
The evaluation of learning takes place by means of an oral interview. The assessment of the student's preparation will take place on the basis of the following criteria: the student's ability to learn and the level of in-depth study of the topics covered, the student's ability to synthesise and expound, and the student's reasoning ability.
The grading follows the following scheme:
|
