Description du Projet

The study of MreB-like proteins requires the use of genetic tools that ultimately reveal morphological, phenotypic or transcriptomic analysis and protein expression. The analysis of different genetic behaviors is an essential point in understanding their functions.

MreB-like proteins are structural homologs of actin and are part of the bacterial cytoskeleton. Inactivation or absence of these proteins has already been shown to influence the shape and / or structure of bacterial cells. From an experimental point of view, it is important to genetically modify the genome of bacteria. This is one of the reasons why it is essential to develop genetic tools adapted to the needs of our team and its model microorganism.

The objective of my activity is to develop and optimize genetic tools that will open new perspectives of investigation for the research of the team.
