Dynamic and Stable Core Microbiota Assist Plants in Enriching Selenium and Reducing Cadmium Absorption.

ABSTRACT: Rhizosphere microbiome is crucial for regulating rhizosphere complex nutrient dynamics. However, mechanisms by which plants regulate rhizosphere microbes to manage nutrient availability under coexisting beneficial and harmful elements remain unclear. This study focuses on the rhizosphere microbiome of Brassica napus in different naturally selenium (Se)-cadmium (Cd)-rich soils, the functionality of this rhizosphere, and the changes in the availability of rhizosphere nutrients. Microbiome analysis, metagenomics, genomic analysis, strain isolation, and functional validation are performed to investigate these relationships. Results show that a significant negative correlation is observed between the rhizosphere available Se and Cd content across the plant whole growth cycle and identified a gr
