BOTN40190 Plants and Stress

Academic Year 2021/2022

Plants, as animals, experience stress during their life time. Whereas the term 'stress' has mainly psychological implications for e.g. humans, 'stress' in plants refers more to the very basic needs of survival - having enough water, nutrients or energy. Plants experience a range of stresses, which can be classified into biotic stresses (such as grazing) or abiotic stresses (such as drought). In this module, we will be focussing on abiotic stresses, in particular drought, salinity, mineral nutrient limitation and heavy metals. Strategies that plants have evolved to cope with these stresses, be it either through 'facing' the stress or evading it, will be reviewed. The approach to this topic will be from the physiological point of view, with examples of underlying molecular mechanisms.

Learning Outcomes:

On completion of this module students should be able to:
- Develop a general understanding of the basic needs of plants and of the strategies that plants use to meet these needs even under adverse environmental conditions (stress);
- Understand stress concepts - the definition and origin of the term 'stress', general and specific responses to stress and basic similarities and differences in the response to stress between plants and animals (e.g. humans);
- Obtain in-depth understanding of responses of plants to the stresses drought, salinity, mineral nutrition and heavy metals;
- Understand the different strategies that plants use to cope with stress and to integrate responses at various organisational levels (e.g. plant, plant organ, tissue, cell);
- Also, advanced oral and group presentation skills.
Criteria for 4th-year level: In-depth understanding of complex responses; providing a synthesis of knowledge of basic processes of plants to understand their performance in a potentially stressful environment; view current stress concepts and plant responses critically.
Learning outcomes are met through oral presentation - topic related to plant stress of choice, requiring initiative; training of advanced oral and group presentation skills - and through an end of semester essay, requiring synthesis of advanced knowledge in a specified amount of time.
