LEARNING OUTCOMES OF THE COURSE UNIT
Provide students with a suitable, even practical, knowledge in advanced Botany, in particular as far as the plant-environment interactions are concerned.
COURSE CONTENTS SUMMARY
References to Cyanobacteria and Chlorophyta. Evolutionary spread of Streptophyta. The lichen symbiosis. Practical examples on lichen employment in bioindication and bioaccumulation. Concept of plant stress and response according to the "LAS" and "GAS" models by Hans Selye. Homeostatic, acclimative and adaptive responses. The gouldian exaptation in the stress responses. Abiotic stress given by drought and flooding, salt, high and low temperature, environmental pollutants. High atmospheric CO2 levels and greenhouse effect. Biotic stress: biotrophic, necrotrophic and emibiotrophic organisms. Plant defense against pathogens: constitutive, locally-elicited and systemic responses. The secondary metabolism in the ambit of the plant-environment interactions.
A complete advanced textbook on the topics dealt with the course is unavailable at present. Thus, scientific articles as well as international book chapters will be recommended to the students from time to time. Other didactic material will be put at students’ disposal in the net.
