Learning objectives
This course is aimed at providing the students with knowledge on genome editing and its potentiality in crop improvement.
Expected learning outcomes
This course will provide the students with knowledge in the following areas:
1. identification of target genes useful in crops protection
2. planning of genome editing experiments
3. analysis of genomic sequences derived from genome editing events
4. in vitro culture setting and lab experience
5. crop pathology phenotypization
