Ree Crispres - Using Crispr-Based Genomic Editing for Crop Protection
A.Y. 2020/2021
Learning objectives
L'obiettivo del corso è quello di fornire conoscenze sul funzionamento del Genome editing e le sue potenzialità nelle specie d'interesse agrario.
Expected learning outcomes
L'attività integrativa prevede di fornire competenze agli studenti nei seguenti ambiti:
1) Identificazione dei geni target per la protezione delle piante di interesse agrario
2) Pianificazione di esperimenti che utilizzino genome editing
3) Analisi di sequenze derivanti da eventi di editing genomico
4) Colture in vitro
5) Fenotipizzazione della malattia

Lesson period
Second semester
The REE laboratory will be conducted in shifts that allow the simultaneous presence of a number of students compatible with current regulations. Compatibly with the health situation, the project developed by the students and selected by the teachers will be presented during a dedicated event.
