Article Synopsis
- Biological nitrogen fixation by microbes like Burkholderia vietnamiensis can enhance nitrogen availability in non-nodulating plants, which was studied using poplar trees as a model.
- The study found dynamic nitrogen-fixing activity in colonies of the bacteria, with only about 11% actively expressing the nifH gene, indicating uneven expression among genetically identical cells.
- Collaborative methods including imaging and metabolomics revealed that nifH expression is localized to the root elongation zone of poplar, highlighting unique interactions between the endophyte and roots.
Phytoremediation, a cost-effective, eco-friendly alternative to conventional remediation, could expand efforts to remediate arsenic-contaminated soils. As with other pollutants, the plant microbiome may improve phytoremediation outcomes for arsenic-contaminated sites. We used and methods to compare the arsenic resistance mechanisms, synthesis of extracellular polymeric substances (EPS), biofilm formation, and plant growth-promoting abilities of the endophytes sp.
