Inhoud
Introduction to Nematoda. History of Nematology. Contributions to Biology. Related
phyla. Abundance and number of species. Functional Organization (I). Gross
morphology, structures, systems, etc.. Digestive system. Cuticle. Functional
implications: survival, molting, growth, parasitism. Locomotion and its physiology;
secretions and feeding. Functional Organization (II). Reproductive system.
Gametogenesis, life cycle, pheromones and sexual attraction. Modes of reproduction.
Genetics of the phyllum. Developmental biology. C. elegans as the biological model of
choice for the XXIth century. Evolution. Major constrains related to the fossil record.
Molecular evolution. Systematics. Taxonomy: principles and different approaches.
Modern molecular biology techniques for taxonomy. Classes Adenophorea and
Secernentea. New approaches and criticism to this system. Ecology of free-living and
terrestrial nematodes. Ecology of soil nematodes. Principles and basis for sampling and
extraction techniques. Feeding habits: microbivorous, fungivores, omnivores, predators
and parasites. Plant parasitism in the orders Dorylaimida and Tylenchida.
Morphological, physiological, ecological and etological adaptations. Types of plant
parasitism: exo-, endo- and semi-endo-. Examples of main plant parasitic nematodes:
symptoms, life cycles, control, etc... Root knot nematodes, cyst, lesion, ectoparasites,
etc... The case of the pinewood nematode, B. xylophilus, in Portugal. Histopathology.
Resistance. Molecular approaches to introduce resistance. The Mi gene system.
Interactions of planta parasitic nematodes with other organisms: viruses (vectors),
bacteria, fungi, mycorrhizae. The important role of virus-vectors (NEPO and TOBRA).
Control of plant parasitic nematodes: chemical, physical, biological, cultural practices,
etc... The role of biological control. Case studies: Pasteuria penetrans and Pochonia
chlamydosporia.
Begincompetenties
This course builds on basic knowledge on General Nematology and Zoology. Basic
understanding of Plant Pathology and Soil Biology is important too.
Eindcompetenties
Students are expected to obtain a broad view of nematodes, their biology and ecology,
be aware of their importance in the biosphere and especially the plant parasitic species.
(Goedgekeurd)
1
Students are expected to recognize and handle plant symptoms caused by nematodes
and learn how to handle these issues. Students are expected to develop their skills on
the practical use of several techniques namely for nematode extraction from soil and
plants, and identification, both morphologically and molecular.

Toelichtingen bij de didactische werkvormen
Lectures taught in a classroom, with permanent connection to the web for clarification
of various aspects of plant nematology. Topics are to be presented as an overview, the
development of which is to conducted by each student out of class. Students will be
encouraged to regularly use the University of Evora e-learning platform (Moodle). Lab
sessions: students are encouraged to use the most common techniques learned in the
course, through the use of different experimental protocols, namely microscopy,
microbiology, PCR and DNA analysis in the Nematology Laboratory (NemaLab) and
develop an individual or group mini-project. A few field trips are also antecipated for
collection of plant and soil material, and to observe field symptoms.
