Molecular microbiology assistant-professor at University of Lyon. I tweet only about Science here. I work on Pectobacteriaceae. I don't like bacteria that can't be genetically manipulated. Lab website: https://sites.google.com/view/mtsb
I find something amiss with this figure depicting the GAC system network in Pseudomonas aeruginosa published here: journals.asm.org/doi/10.1128/... Should the RsmA binding sites be represented as a double-stranded helix? 🤔 It’s confusing about what this protein actually does. Don't you think ?
Nous recrutons un Maître ou une Maîtresse de conférences en bactériologie moléculaire pour notre équipe MTSB au laboratoire MAP à Lyon, France. Le poste combine recherche sur l'adaptation des bactéries phytopathogènes et enseignement en génétique microbienne. Notre team : sites.google.com/view/mtsb
New pub. from the lab ! We discovered that potato tubers exert intense selective pressure during Dickeya solani infection, driving the rapid emergence of mutations in the sRNA ArcZ. These mutations lead to the appearance of "social cheaters" that sweep through the pop. in as few as 30 generations.

Throwing a spotlight on genomic dark matter: the power and potential of transposon-insertion sequencingLinking genotype to phenotype is a central goal in biology. In the microbiological
field, transposon mutagenesis is a technique that has been widely used since the 1970’s
