Learning unit contents

About 30 years ago, it became apparent that the study of the diversity of marine microorganisms cannot be conducted without a molecular approach, given that only a fraction of them can be isolated and cultured. In addition, as for the microorganisms that can be observed through a microscope, genetic diversity is larger than that which is determined on the basis of phenotypical characteristics (morphology....). The determination of diversity at the genetic level also allows us to understand ecological characteristics (geographical distribution, endemism, etc.). Rencently, the metagenomic tools have allowed a deeper understanding of the evolutionary processes and the metabolic pathways of marine microorganisms.

Learning outcomes of the learning unit

To give to the students the knowledge that will allow them, on one hand, to understand and read in a critical manner the literature concerning the diversity of marine microorganisms, and on the other hand, to use molecular techniques in order to solve problems concerning the molecular diversity and ecology on which they may be working (master thesis, PhD, etc).

Prerequisite knowledge and skills

Having basic knowledge of genetic material: DNA, RNA, proteins. If this prerequisite is not met, part of the course may be devoted to a review of the basic knowledge, on request of the students concerned.

Planned learning activities and teaching methods

Practical work in a laboratory on a problem of caracterisation of the molecular diversity of marine microorganisms (often cyanobacterial strains of the BCCM/ULC collection). The steps are the DNA extraction, PCR of a section of the rRNA operon and bioinformatic sequences analyses.

Mode of delivery (face to face, distance learning, hybrid learning)

Face-to-face course

Further explanations:

 

Face-to-face teaching, in the 1st quadrisemester

 

1) Definitions and why?

2) Systematics, the notion of bacterial species and molecular markers of diversity

3) How is generated the genetic diversity at the basis of evolution?

4) Phylogenetic analyses and the construction of phylogenetic trees

5) Molecular microbial ecology

6) Practical work with extraction of genomic DNA from strains, PCR, electrophoresis, sequencing, analysis of sequences obtained during practical work

7) Genomic approaches (Dr. Luc Cornet course)

    - Reminder of the basics on genomic diversity and the contribution of genomes for taxonomy and evolution (with example of cyanobacteria)

     - Phylogenomics

    - How to study metabolic pathways with bioinformatics?

    - Reproducibility in bioinformatics

     - A concrete example
