The course deals with developmental biology of plants and environmental constrains upon plant growth. Focus is on regulation of cell division, meristem activity, plant stem cells, embryogenesis and organogenesis, signal transduction and plant hormones. The basic concept of general growth and development will be introduced, treating how specific plant organs develop as the plant grows from an embryo to a flowering plant. How does the cell cycle and growth control contribute to plant development and how is cell cycle and growth controlled, how are cell walls and metabolism integrated into development. How do stresses impact on growth and development and what kind of molecular mechanisms underly these processes.
