Characterization of the beneficial effect of Enterobacter sp. SA187 on Arabidopsis thaliana growth under low nitrogen conditions - Monday, January 19th 2026 11 am, INRAE, Versailles
Reducing the use of synthetic nitrogen fertilizers is a major challenge for sustainable agriculture. To this end, we investigated the interaction between the endophytic bacterium Enterobacter sp. SA187 and Arabidopsis thaliana under low nitrate conditions. Interestingly, SA187 significantly enhanced plant growth and shoot nitrogen content by improving nitrate uptake and nitrogen allocation. These effects were associated with the regulation of high-affinity nitrate transporters, particularly NRT2.5 and NRT2.6, partly mediated by ethylene signaling. Our findings highlight SA187 as a promising microbial partner to improve nitrogen-use efficiency under nutrient-limited conditions.
