Tim Schnabel; Elizabeth Sattely ACS Synthetic Biology 2021. doi:10.1021/acssynbio.1c00287
Other claims from this paper (6)
- Mechanism Multicopy uAT induces ammonia release through glutamine synthetase deactivation.
- Intervention effect Multicopy stable strains improved Setaria viridis growth promotion compared with single-copy strains in hydroponic monoassociation.
- Intervention effect Inoculation did not increase Zea mays growth promotion relative to WT in nitrogen-poor nonsterile soil.
- Mechanism Strain health, competition or colonization may limit growth promotion in soil.
- Intervention effect Engineered strains fixed more nitrogen per cell than WT.
- Recommendation The authors recommend balancing multicopy uAT expression to maximize ammonia production and avoid fitness defects.
