Course objectives
At the end of this course, students should be able to: know the development of angiosperm reproductive organs; to understand the processes of pollen-pistill interactions; to explain the process of double fertilization in angiospers and to interpret seed development. Regulation of above mentioned processes will be illustrated on selected plant models.
Syllabus
  • Seed as a start of a new life cycle: angiosperm seed structure (testa, endosperm, aleuron layer, embryo: embryonal axis, cotyledones, hypocotyl), seed quiescence and dormancy, seed germination, seedling structure.
  • Mitosis - nuclear division: Cell cycle, cytoskeleton formation during cell cycle, polarity, asymetric divisions, squash methods, pretreatments for karyology, cell cycle synchronization.
  • Morphology of the vegetative stem apical meristem (structure, stem cells, leaf primordia and leaf meristems, leaf differentiation); root apical meristem (quiescent centre, root cap, columela).
  • Megagametogenesis, gynaeceum, pistil, angiosperm ovule structure, clearing methods of plant ovules, observation of cleared ovules by means of Nomarski DIC.
  • Microsporogenesis and microgametogenesis, androeceum, stamen: anther and filamentum, structure of the anther wall, tetrades, types of pollen grains, differential staining of pollen grains, determination of pollen viability.
  • Pollen grain germination in vitro, phase contrast microscopy.
  • Pollen - pistil interaction: pollen tube growth, callose plugs, decolorised aniline blue staining, fluorescence microscopy in UV light.
  • Cryostat sections in embryology - fixation, cryoprotection, cryo-sectioning (cryostat), enzyme histochemistry, histochemical reactions of hydrolytic enzymes.
  • Histologic techniques in plant embryology I. - fixation of isolated organs.
  • Histologic techniques in plant embryology II. Dehydration of samples, paraffin and resin embedding, microtome sectioning, adhesion of sections, de-waxing of sections.
  • Histologic techniques in plant embryology III. Succesive double staining of sections, dehydration and Eukitt mounting.
  • Documentation of prepared microscopic preparates - drawings, measurements, micrographs, automatic analysis of images.
