Syllabus
Prerequisites: Basic knowledge of Plant Physiology is essential for understanding the topics covered.
Target skills and knowledge: The course aims to provide, also through the presentation of case studies, an understanding of the morphological and physiological mechanisms underlying the adaptation of plants to the environment.
Examination methods: The exam is written and consists of open questions.
Assessment criteria: The test consists of a few questions requiring a longer, more elaborate, response and others with a short answer, probing the preparation of all subjects covered.
Course unit contents: General definition of stress and common avoidance and tolerance strategies: production of reactive oxygen (ROS), nitrogen (RNS) and sulfur (RSS) species, activation of the antioxidant system, hormonal regulation, epigenetic modifications. Adaptation vs. acclimation.
High light stress. Photoinhibition and photoprotection. Regulation of photosynthesis to environmental dynamics. Regulation of light harvesting. Regulation of photosynthetic electron transport. Non-photochemical dissipation of light energy. Xanthophylls cycles, PSII damage and repair mechanisms. Regulation of carbon fixation. Adaptation of photosynthesis during evolution.
Low light intensity adapted plants. Sciaphilous plants: morphogenetic and physiological features. High light intensity adapted lants. Heliophilous plants: morphogenetic and physiological features.
Excess water stress. Flooding (flooding) and submersion. Molecular, cellular and organismic damages. Fermentation and acidification of the cytoplasm. Ethylene in flooding stress. Avoidance and tolerance mechanisms in partially submerged (amphibious) plants. Adaptive responses to hypoxia and anoxia. NO and plant hemoglobins. Morphogenetic adaptations of plants to submersion. Photosynthesis under water. Carbon concentration mechanisms in submerged plants.
Drought stress. Molecular, cellular and organismic responses. The xerophytes. Morphogenetic and physiological mechanisms of dry resistance. Tolerance to extreme desiccation: true poichilohidrich and resurrection plants.
Salt stress. Morphogenetic and physiological strategies of salt resistance. Halophytes. Osmoregulation. Mechanisms for regulating the absorption and accumulation of NaCl in plants. The SOS system.
Cold stress and freezing stress. Cell damage and adaptive responses. Osmoregulators and cryoprotectants. The parietal antifreeze proteins. Adaptation to winter desiccation and protection mechanisms of photosynthetic apparatus in evergreen plants.
Stress from anthropogenic pollution. The example of heavy metals. Characteristics, toxicity and tolerance mechanisms. Detoxification systems. Metal hyperaccumulator plants: mechanisms and function of hyperaccumulation. Phytoremediation and rizofiltration. Current experimental approaches for the use of tolerant or hyperaccumulator plants in the purification of aquatic and terrestrial sites polluted by heavy metals.
Planned learning activities and teaching methods: The course consists only of lectures. The teacher, for some themes, will complement purely theoretical lessons with analysis of scientific articles with attention to the most current methodologies used in the study of plant ecophysiology.
Additional notes about suggested reading: No textbooks covering all the topics covered in the course are available. All the lesson slides will be provided to students through e-learning as well as in-depth articles.
