Structure AGRARIA [AG]
Course of Study SCIENZE E TECNOLOGIE AGRARIE (DM270) [AG0056 2008]
Prerequisites: The student needs to know the basic aspects of cell biology and reproductive biology, with particular reference to the main livestock and crop species.
Basic knowledge and abilities: The student is expected to gain basic knowledge and expertise of formal genetics useful for improving and breeding livestock and crop species, with particular reference to the inheritance of phenotypic variation and its heritability. The student should be able to examine the genetic aspects of the expression of both qualitative and quantitative traits, to analyze the genetic structure of populations and to evaluate the genetic traits of reproductive systems mainly affecting the characterization, selection and conservation of populations.
Examination procedures: Students will deal with both a written test (in progress) and an oral examination (at the end of the course).
Evaluation parameters: The student will be evaluated on the basis of theoretical knowledge on the genetics of mendelian and quantitative traits, population genetics, molecular genetics and cytogenetics, including elements of genetic mutations and biotechnologies.
Topics: Mendelism and inheritance of qualitative traits. Molecular genetics: The structure of nucleic acids. Mechanisms of replication, transcription and synthesis of proteins. Sources of genetic variation: recombination and mutation. Molecular bases of gene expression. Genetic control of quantitative traits and heritability estimates. Population genetics: Hardy-Weinberg equilibrium.
Genetics of reproductive systems: Processes of sporogenesis, gametogenesis and embryogenesis in the Angiosperms. Anfimixis: autogamy, allogamy and their effects on the genetic structure of populations. Apomixis and clonal populations. Reproductive barriers: genetics of incompatibility and malesterility.
Genetic breeding: Fundamentals of selection and methods for the constitution of varieties in the major crops. Varieties based on pure lines, hybrids, synthetics and clones. Registration of varieties. Conservative varietal selection and commercial seed production.
Genetic biotechnologies: Elements of molecular biology and genetic engineering. Genetically modified organisms (GMO) and transgenic varieties. Molecular marker-assisted breeding (MAB). The genetic identity of varieties and genetic traceability of agrifood products and derivatives.
Activities of learning and teaching: The course includes classroom lectures of general genetics and practical laboratory activities of molecular genetics, for a totale of 64 hours.
Supplementary materials for studying: The materials used for frontal lessons and practical activities (pdf files of presentations) of Genetics will be made available on request.
