Summary : Minerals and rocks represent essential reservoirs of nutritive elements for the long-lasting functioning of forest ecosystems developed on nutrient-poor soils. While the presence of effective mineral weathering bacteria was evidenced in the rhizosphere of different plants, the mol. mechanisms involved remain uncharacterized. To fill this gap, we combined transcriptomic, proteomics, geo-chem. and physiol. analyses to decipher the potential mol. mechanisms explaining the mineral weathering effectiveness of strain PML1(12) of Caballeronia mineralivorans. Considering the early-stage of the interaction between mineral and bacteria, we identified the genes and proteins differentially expressed when: (i) the environment is depleted of certain essential nutrients (i.e., Mg and Fe), (ii) a mineral is added and (iii) the carbon source (i.e., glucose vs mannitol) differs. The integration of these data demonstrates that strain PML1(12) is capable of (i) mobilizing iron through the production of a non-ribosomal peptide synthetase-independent siderophore, (ii) inducing chemotaxis and motility in response to nutrient availability and (iii) strongly acidifying its environment in the presence of glucose using a suite of GMC oxidoreductases to weather mineral. These results provide new insights into the mol. mechanisms involved in mineral weathering and their regulation and highlight the complex sequence of events triggered by bacteria to weather minerals.
