Regulation of plant Ni uptake by soil-borne microorganisms occurs independently of their Ni-solubilizing capabilities.

ABSTRACT: Plant-associated microbial communities play a vital role in host adaptation to environmental stress, yet their contributions to plant nickel (Ni) tolerance strategies remain unclear. It is not understood whether the same microbial community elicits similar responses across different plant species or regulates stress adaptation in a host-specific manner. Although microorganisms influence plant responses to metal toxicity by altering metal bioavailability in the rhizosphere, their potential to optimize plant metal uptake is less explored. In this study, we evaluated whether synthetic microbial communities enhance Ni uptake in two species with contrasting metal strategies: the hyperaccumulator Odontarrhena chalcidica and the Ni-excluding Arabidopsis arenosa. We hypothesized that soil microorg
