Course objectives
At the end of the course, students will understand how the unique features of plants affect plant evolution. Students will adopt the basics of contemporary evolutionary thinking and, consequently, they will be able to assess seemingly self-evident phenomena of plant biology through the new optics.
Learning outcomes
Students will: • - understand the essence of the fundamental evolutionary mechanisms (natural selection and genetic drift) - learn how natural selection and genetic drift affect plant biology and ecology - understand mechanisms of plant speciation - be able to interpret plant traits on the level of genes, individuals, populations and species in the evolutionary context - be able to apply the aquired knowledge in their own research and formulate new evolutionary hypotheses
Syllabus
  • The discussed mechanisms and principles also apply for algae and fungi.
  • • 1. Diversity of life, biological evolution, (neo)darwinism, natural selection, genetic drift, the selfish gene. Evolutionary significant features of plants that differentiate them from animals (e.g., modular and indetermined growth, dormancy, seed bank, different distribution along fast-slow continuum axes).
  • • 2. Nature is continuous and its fuzzy boundaries contrast with a human tendency to think in categories. Difficulties with species concepts. What is a species? Taxonomic species vs Evolutionary species and their role in species concepts. Species in plant evolution.
  • • 3. Plant speciation. Prezygotic/prepollination and postzygotic/postpollination reproductive barriers. Bateson–Dobzhansky–Muller model (BDM).
  • • 4.-5. Hybrid speciation - homoploid and polyploid. The role of hybridization in plant speciation, its mechanisms and incidence in plants.
  • • 6. Plant breeding systems and their evolutionary consequences. Sexual and asexual reproduction and their pros and cons in small and large evolutionary scales.
  • • 7. Somatic mutations - the impact of intraindividual evolution of cell lines on plant microhabitat adaptations and evolution in general. Mechanisms of intraindividual evolution (transposon mutagenesis, mitotic cross-over etc.). Somatic mutations in breeding and agriculture. •
  • • 8. Life history and reproductive strategies of plants in evolutionary consequences. The effects of plant longevity, rate of reproduction, dormancy, seed bank etc. on plant demography and evolution.
  • • 9. Evolution of genome size and genomic GC content in plants (variability range in plants, their extremes, ecological and evolutionary consequences, nucleotype effect, intraspecific variation)

Teaching methods
Lectures using powerpoint presentations as a guidline. The goal is to understand the core of the problem based on illustrative examples, not to memorize lists of rules and terms. Study materials include both research and review articles that are relevant to themes discussed.
Assessment methods
oral examination
Language of instruction
Czech
