Plant Molecular Genetics (2018/2019)
Scientific Disciplinary Sector (SSD)
AGR/07 - AGRICULTURAL GENETICS
The teaching is organized as follows:
The course examines the main strategies of plant genetics and crop improvement. Molecular markers and tools for gene expression analysis and improvement of crops are addressed. Objective of the course is also the evolution of crop species, sinteny, plant genome structure and genetic variability useful for crop improvement. Aspects of plant biotechnology for improving crop species to increase yield and quality of products obtained by cultivation.
The objective of the laboratory of Plant Molecular Genetics is to introduce students to several methods useful for the molecular genetic analysis. The techniques used are strictly related to the topics covered during class lectures.
