The course aims to provide students with the fundamental basics of plant physiology using the knowledge acquired in courses in Plant Biology, General and Inorganic Chemistry, Organic Chemistry, Biochemistry and Molecular Biology. The course starts from the study of the main cellular organelles to reach basic themes such as photosynthesis, nutrient transport, plant hormones and light regulation of growth and development processes. The student must: know the fundamental role of water for plant life; to learn the biochemical and biophysical mechanism of photosynthesis in reactions to light and in those of carbonation; to identify the cause-effect relationships between the different physiological phenomena by framing them in a wider context of metabolic and environmental interactions. Acquire knowledge on biotechnological techniques used to improve the quality, yield and stress resistance of plants.

Secondary metabolites and plant defense mechanisms.
Genetic transformation of plant organisms: plants as bioreactors for the production of biopharmaceuticals and proteins of pharmaceutical / industrial interest. Use of genetic transformation to increase resistance to pathogens or abiotic / biotic stresses, increase in the nutritional value of crops.

Plants and climate change, possible biotechnological interventions on plant molecular mechanisms for the reduction of atmospheric CO2 content.

D1-Knowledge and understanding. Students must have critically and thoroughly assimilated the main themes of plant physiology (transport, photosynthesis, metabolism, mineral nutrition, photo morphogenesis, hormonal regulation) as well as having acquired knowledge of plant-environment interactions and stress responses.
D2 - Ability to apply knowledge and understanding. Students will be able to identify the cause-effect relationships between the different physiological phenomena and place them in a wider context of metabolic and environmental interactions. They will have to have acquired knowledge on the main methodological procedures (biochemical, biomolecular and biotechnological) and instrumental used for biological research and their fields of application, as well as developed a scientific approach to bioethical problems (see GMOs).
D3 - Autonomy of judgment. Students must be able to interpret and predict the physiological responses of the plant. Demonstrate conscious judgment autonomy with reference to evaluation and interpretation of experimental laboratory data and ability to compare with existing data in the literature.
D4 - Communication skills. Students will be prepared to use a specific technical language to communicate information and ideas related to the knowledge learned during the course. Acquisition of adequate skills and tools for communication with reference to data processing and presentation.
D5 - Ability to learn. Students, thanks to the theoretical skills acquired, will be able to understand and critically discuss the salient aspects of plant physiology. Moreover, thanks to the use of the available databases, they will be able to deepen and update their knowledge. The verification of the ability to apply the acquired knowledge will take place through: a) classroom discussion and problem solving and b) passing the exam.

Assessment

Oral interview. The exam consists of a series of three to four questions that require the discussion of the proposed topic and links with others in order to evaluate, in addition to the acquired knowledge and reasoning skills, also the communication and problem-solving skills of a practical nature in accordance with what is indicated by the Dublin descriptors

Disabilità e DSA

Le studentesse e gli studenti che hanno registrato la certificazione di disabilità o la certificazione di DSA presso l'Ufficio Inclusione e diritto allo studio, possono chiedere di utilizzare le mappe concettuali (per parole chiave) durante la prova di esame.

A tal fine, è necessario inviare le mappe, due settimane prima dell’appello di esame, alla o al docente del corso, che ne verificherà la coerenza con le indicazioni delle linee guida di ateneo e potrà chiederne la modifica.

The student can request to sit the final exam in English with the following  bibliography:

 Plant Physiology and Development, Sixth Edition by Lincoln Taiz, Eduardo Zeiger, Ian M. Møller, and Angus Murphy, published by Sinauer Associates.
