Learning outcomes

Module: FISIOLOGIA DELLA PRODUZIONE
-------
The general objective of the course is to provide a link between physiological and molecular processes responsible for plant growth and development and more applied aspects of yield production by crop plants.


Module: FISIOLOGIA DELLO STRESS
-------
The course is intended as an integration point between the contributions of biochemistry, biophysics, molecular and genetic biology and physiology in understanding abiotic stress response, one of the fundamental problems of plant biology: cold, drought, warmth, excess light, mineral deficiencies, toxicity . The course includes a general section addressing the common features of environmental stresses and the methods for identifying phenotypes and genes involved in resistance. The role of oxidative stress I central: its origins, characteristics and molecular species involved will be discussed in detail. Cellular and molecular structures involved in stress response will be described and their interactions will be highlighted. A case study will be dealt with on the biotechnological use of the knowledge acquired from the study of stress biology.

Key words: ecofisiology, physiology of plant production, biophysics, molecular genetics.

Syllabus

Module: FISIOLOGIA DELLA PRODUZIONE
-------
The program includes: Analysis of plant growth: basic concepts. Interception of solar radiation. Photosynthetic efficiency; photosynthesis, photorespiration, carbon accumulation mechanisms; effects of atmospheric carbon dioxide increase. The partitioning of dry matter: assimilate allocation, phloem transport and distribution to harvesting organs. Water use efficiency. Nitrogen use efficiency and biological nitrogen fixation. Mycorrhiza and phosphorus absorption. Reproductive growth: fruit set and development, hormonal regulation. For each lesson, examples of biotechnological applications aimed at improving plant productivity are presented and discussed.

Assessment methods and criteria

Module: FISIOLOGIA DELLA PRODUZIONE
-------
oral


Module: FISIOLOGIA DELLO STRESS
-------
The exam will be organized in two parts.
(A) At the beginning of each call, candidates will receive a request to reply in writing within 45 minutes. It will cover one of the preparatory aspects of the course and may include the presentation of general schemes and the compilation of the metabolic pathways involved.
B) Among the choice of articles provided by the teacher each candidate must choose one of his / her own interests and give a brief presentation on the basis of slides prepared for the purpose. During the presentation, general questions will be asked about the program


Didactic Material: The topics discussed in the course are hardly found in a textbook. Many parts of interest are discussed in:

Buchanan et al. : Biochemistry and Molecular Biology of Plants, Zanichelli. Basic text for the study of Plant biology.
Salisbury and Ross: Plant Physiology. Blackwell. A text of Classical Physiology, particularly suitable for the study of phenotypes.
Nobel: Biophysical Plant Ecology. It illustrates the basic phenomena of plant biology with formal and methodological rigor.

The Teacher will make available the pdf of the lessons and a series of complementary articles that will make the basis for a more detailed preparation.
NB: IN NO WAY THE TEXT CONTAINED IN THE DIAPTULE CAN BE CONSIDERED SUFFICIENT TO A COMPLETE AND SUBSEQUENT PREPARATION OF THE TEXT BOOK.
