The course is aimed to furnish useful elements to the understanding of the plant metabolism. To achieve this objective the students must understand a) how the plants are able to use the solar energy to assimilate the inorganic carbon and to convert it through different biosyntheses into molecules and complex organic structures composing the plant cell; b) how the plants are able to take up mineral elements and water from the environment and to redistribute them inside the different parts of the plant; c) how the plants are able to develop and to regulate their own growth, also in relationship to the environmental stimuli. The mechanisms of the response and adaptation of the plants to stress conditions will be deepened with particular attention to formation and scavenging of reactive oxygen species.

Educational objectives
The course is aimed to furnish useful elements to the understanding of the plant metabolism. To achieve this objective the students must understand a) how the plants are able to use the solar energy to assimilate the inorganic carbon and to convert it through different biosyntheses into molecules and complex organic structures composing the plant cell; b) how the plants are able to take up mineral elements and water from the environment and to redistribute them inside the different parts of the plant; c) how the plants are able to develop and to regulate their own growth, also in relationship to the environmental stimuli. The mechanisms of the response and adaptation of the plants to stress conditions will be deepened with particular attention to formation and scavenging of reactive oxygen species.
Prerequisites
Prerequisite that the student must have to fully understand the contents of the course is the knowledge of general botany (Plant citology and morphology). Important prerequisite is considered the knowledge of fundamentals of general chemistry, inorganic and organic.
Teaching methods
Face-to-face lectures.
Learning verification modality
The exam consists of an oral test of about 30 minutes long aiming to ascertain the knoldge level and the understanding capability acquired by the student. The oral exam will also test the student communication skills and his autonomy in the organization and exposure of different topics.

PLANT METABOLISM: Assimilation of mineral elements: uptake and assimilation of nitrate. Synthesis of aminoacids. Biological fixation of nitrogen.

SECONDARY METABOLITES: terpens, alkaloids and flavonoids.

BIOTIC AND ABIOTIC STRESSES

During the course will be carried out four lab exercitations and seminars.
