The increasing atmospheric CO2 content (pCO2) is likely to modify the ecosystem functioning including rhizosphere bacteria that are directly dependent on rhizodeposition. This may include alteration of Pseudomonas populations that display phenotypic traits in relation with plant fitness. In the present study, 1228 Pseudomonas strains were isolated from the...
