Pneumococcal competence, a populational health sensor driving multilevel heterogeneity in response to antibiotics.

M. Prudhomme, C. H. G. JOHNSTON, A.-L. Soulet…·P. Polard

This study reveals a populational QS mechanism in Streptococcus pneumoniae that drives antibiotic response heterogeneity through competence-induced bet-hedging.

The RecA-directed recombination pathway of natural transformation initiates at chromosomal replication forks in Streptococcus pneumoniae.

C. H. G. JOHNSTON, R. HOPE, A.-L. SOULET…·P. POLARD

This study shows that RecA and DprA accumulate at replication forks during natural transformation in Streptococcus pneumoniae, linking HR with replication.

The alternative sigma factor σX mediates competence shut-off at the cell pole in Streptococcus pneumoniae.

C. H. G. Johnston, A.-L. Soulet, M. Berge…·P. Polard

This study identifies σX as a key regulator that spatially coordinates competence shut-off by anchoring DprA at the cell pole in Streptococcus pneumoniae.
