COURSE CONTENT

LECTURES

1. Introduction in plant physiology: historical overview, literature, difference between plants and other organisms, plant cell features. 2. Water and plants: absorption, transport and water loss: role of water in plants, water absorption processes, water potential, regulation of water balance, water transport: cohesion-tension theory and root pressure, water loss: transpiration and guttation, mechanisms and regulation of stomata opening. 3. Mineral nutrition and assimilation of mineral nutrients: essential nutrients: absorption and function, mycorrhizae, halophytes, nitrate and ammonium assimilation, biological nitrogen fixation, sulphur, phosphate, cation and oxygen assimilation. 4. Solute transport: passive and active transport, mechanisms of solutes transport in cells, tissues and entire plant. 5. and 6. Photosynthesis: chemoautotrophy and photoautotrophy, photosynthesis in algae and bacteria, photosynthesis in plants, structure of ptotosynthetic apparatus, light reactions, Calvin cycle, photorespiration, C3, C4 and CAM plants, effects of environmental factors (light, CO2, temperature) on photosynthesis rate, translocation of photosynthesis products: source-to-sink pathway; heterotrophy: parasitic and carnivorous plants. 7. Respiration and lipid metabolism: aerobic respiration: glycolysis, Krebs cycle, electron transport and ATP synthesis, anaerobic respiration: alcoholic and lactic acid fermentation, effects of environmental factors on respiration rate; whole-plant respiration; lipid metabolism, mobilization of storage lipids and proteins. 8. Growth, differentiation, development and senescence: intracellular and intercellular regulations: signal transduction; growth: meristems; differentiation: polarity of plant cell; senescence and programmed cell death: mechanism and consequence; abscission of organs. 9. and 10. Plant growth regulators (plant hormones): auxins, gibberellins, cytokinins, ethylene and abscisic acid: discovery, structure and biosynthesis, metabolism, transport, effects, mechanism of action. 11. Influence of temperature on plant growth and development: bud and seed dormancy: coat-imposed dormancy and embryo dormancy, plant growth regulators and dormancy. 12. Influence of light on plant growth and development: photomorphogenesis, phytochromes: properties, localization, mechanism of action, function; circadian rhythms; control of flowering: autonomous regulation; short-day, long-day and day-neutral plants, vernalization, signals involved in flowering, inhibition of flowering, plant growth regulators and flowering. 13. Plant defense: surface protection and secondary metabolites: cutin, suberin and waxes, terpenes and phenolic compounds, nitrogen-containing compounds: biosynthetic pathways, distribution in plants, mode of action, function. 14. and 15. Stress physiology: water defficit an drought resistance, low temperatures: chilling and freezing, high temperatures: heat stress and heat shock, salinity stress, oxygen deficiency: anaerobic stress, light and UV stress, air and soil pollution, biotic stress, oxidative stress.
