Course objectives
The aim of this course is acquaint the students with the most prevalent type of symbiosis on the Earth - mycorrhizal symbiosis, which substantially affects ecophysiological functioning of almost 90% of vascular plant species.
Learning outcomes
After passing this course, students are able to:
identify and characterize different types of mycorrhizal symbioses;
position the organisms involved with respect to current systematics;
compare them as regard their functioning and placement within symbiotic continuum;
discuss impact of these symbioses on plant growth and fitness and on natural as well as agroecosystems.
Syllabus
  • Symbiosis - concept, mutualism, parasitism, comensalism, neutralism, competition, facultative and obligate symbionts.

  • Mycorrhizal symbioses - arbuscular mycorrhiza, ectomycorrhiza, ectendomycorrhiza, orchid, arbutoid, monotropoid and ericoid mycorrhiza. Occurrence 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, saprotrophic and pathogenic soil-borne fungi. The effects on host growth and competition abilities. The role in plant community structure. Mycoheterotrophy. The role of mycorrhizas in life cycle of host plants.

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