Termine (iCal) - nächster Termin ist mit N markiert

VB: 01.10.2019 at 11:00; first lecture (in total 4 lectures): 08.10.2019 11:00.
Practical course (in the cytogenetic laboratory, work in pairs) will be blocked in December: 02-06.12.2019
Due to the fact that the practical work will be done in in the cytogenetic laboratory (work in pairs, each group has own set of species to analyze) the number of participating students is limited to 8 per course.

Ziele, Inhalte und Methode der Lehrveranstaltung

The purpose of the course is two-fold. First, it offers an overview of plant cytogenetic techniques: from traditional chromosome counting to more recently established techniques of chromosome painting (in situ hybridization) and immunocytochemistry. Second, it presents detailed and up-to-date information about plant chromosome structure (centromere, telomere etc.) and main types of DNA sequences used for cytogenetic analyses. The newest methods developed recently to analyse genome composition and to characterize different types of repetitive DNA is plant genomes (high-throughput sequencing) will also be introduced. The course introduces also types and consequences of chromosome rearrangements including polyploidy, in the context of chromosome evolution. The use of cytogenetic data (obtained from both classical and molecular cytogenetic studies) in inferring plant taxa relationships and in evolutionary studies of different plant groups will be discussed. The course will give the up-to-date overview of the state-of-art in the analyses of plant chromosomes.
The practical part of the course will include chromosome preparation in selected groups of plants, as well as classical and molecular chromosome staining methods. The students learn to perform DNA:DNA in-situ hybridization (FISH), in particular to prepare and label the DNA probes (e.g., species-specific repetitive DNA, rDNAs, telomeric sequences), to detect of the hybridization sites and to analyse the obtained data (fluorescence microscopy). The students will acquire practical skills in chromosome handling and will learn to analyse and interpret chromosomal data in evolutionary context.

Mindestanforderungen und Beurteilungsmaßstab

- To introduce modern techniques used nowadays to study the structuure and function of plant genomes and to emphasize the importance of such analyses as complementary approach for phylogenetic, evolutionary, or populational studies.

- To introduce methods for in situ-hybridization probe preparation and labelling, chromosome preparation and quality checks, and finally in situ hybridization

Students can further apply this knowledge to analyse and to interpret obtained results (microscopy).


- Lectures
