Course objectives
The aim of the course is to familiarize the students with mycorrhizal symbioses formed by plant roots as host environment. These symbioses are formed by majority of plant species around the World and they affect significantly plant nutrient and water uptake, growth and competition abilities. Attention is also paid to symbiotic fixation of N2 and to relationships to other soil microorganisms. Proper student's interests: ecophysiology of plant mineral nutrition, plant ecology, nutrient uptake in agroecosystems, plant competition abilities.
Syllabus
  • Symbiosis - concept, mutualismus, parasitismus, comensalismus, neutralismus, competition, fakultative and obligate symbionts.

  • Mycorrhizal symbioses - (vesicular-)arbuscular mycorrhiza, ectomycorrhiza, ectendomycorrhiza, orchid, arbutoid, monotropoid and ericoid mycorrhiza. Occurence and taxonomy of symbionts. Intraradical and extraradical structures. Ecophysiological functions of mycorrhizas (model of multifunctionality). Effects on host metabolism - nutrient flows between symbionts (carbohydrates, phosphates and other low mobile nutrients, nitrogen compounds, water). Relations to other soil microorganisms - bacteria, pathogenic soil-borne fungi. The effects on host growth and competition abilities. The role in plant community structure. Plant achlorophylly. The role of mycorrhizas in life cycles of host plants.

  • N2 fixators. Taxonomy of the symbionts. Biochemical pathways of N2 fixation. Dual symbioses. The effects on plant growth and plant communities.
