MICOLOGIA E VIROLOGIA VEGETALEModule VIROLOGIA VEGETALE
Academic Year 2022/2023 - Teacher: MATILDE TESSITORIExpected Learning Outcomes
The course aims to provide students with the fundamental knowledge of Plant Virology useful for the recognition, 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 teaching will be done through lectures (28 hours) for the acquisition of basic knowledge together with laboratory exercises, case study discussions as well as educational visits to companies in the agri-food sector to develop the ability to apply basic knowledge (28 hours).
If teaching is given in a mixed formula or remotely, necessary changes may be introduced to what was previously stated in order to comply with the provided and reported syllabus. Learning assessment may be done remotely if necessary.
As guarantee of equal opportunities and in compliance with current laws, interested students can ask for a personal interview in order to plan any compensatory and/or dispensatory measures, based on their specific needs and on teaching objectives of the discipline. It is also possible to ask the departmental contacts of CInAP (Center for Active and Participatory Integration - Services for Disabilities and/or DSAs), in the persons of professors Giovanna Tropea Garzia and Anna De Angelis.
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.
-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:
Unsuitable
Knowledge and understanding of topic: Significant deficiencies. Significant inaccuracies
Ability to analyse and synthesise: Irrelevant. Frequent generalisations. Inability to summarise
Use of references: Completely inappropriate
18-20
Subject knowledge and understanding: At threshold level. Obvious imperfections
Capacity for analysis and synthesis: Barely sufficient capacity
Use of references: Barely appropriate
21-23
Knowledge and understanding of the subject matter: Routine Knowledge
Ability to analyse and synthesise: Is able to analyse and synthesise correctly. Argues logically and coherently
Use of references: Uses standard references
24-26
Knowledge and understanding of subject matter: Good knowledge
Analysis and synthesis abilities: Has good analysis and synthesis abilities. Arguments are expressed coherently
Use of references: Uses standard references
27-29
Knowledge and understanding of the subject: Knowledge more than good
Capacity for analysis and synthesis: Has considerable capacity for analysis and synthesis
Use of references: Has deepened the arguments
30-30L
Knowledge and understanding of the subject: Very good knowledge
Capacity for analysis and synthesis: Has considerable capacity for analysis and synthesis.
