|---|---|---|
| 1 | Nitrogen metabolism: Nitrate uptake, structural features of nitrate reductase and nitrite
reductase, incorporation of ammonia into organic compounds, regulation of nitrate
assimilation. Biological N2-fixation: Biological nitrogen fixation by free living and in symbiotic association; structure, function and mechanism of action of the enzyme nitrogenase, strategies for protection of nitrogenase from inhibition by oxygen; structure of nodule, role of leghaemoglobin; Ammonia assimilation: Synthesis of amides and ureides, transport of assimilated nitrogen to aerial parts. |

| 2 | Secondary metabolites: Special features of secondary plant metabolism, terpenes, lignin,
tannins, pigments, phytochrome, waxes, alkaloids, nicotine, functions of alkaloids, cell wall
components. Toxins of plant origin – mycotoxins, phytohemagglutinins, lathyrogens, nitriles, protease inhibitors, protein toxins. Stress metabolism in plants – Environmental stresses, salinity, water stress, heat, chilling, anaerobiosis, pathogenesis, heavy metals, radiations and their impact on plant growth and metabolism, criteria of stress tolerance. Antioxidative defense system in plants – reactive oxygen species and their generation, enzymic and non-enzymic components of antioxidative defense mechanism. |
