Enhancement of Arabidopsis Growth by Enterobacter sp. SA187 Under Elevated CO(2) Is Dependent on Ethylene Signalling Activation and Primary Metabolism Reprogramming.

Enterobacter sp. SA187 enhances Arabidopsis thaliana growth under elevated CO2, and the effect depends on ethylene-signaling activation plus extensive plant gene-expression and primary-metabolism reprogramming.

• Why it matters: Elevated CO2 can alter plant physiology, but the mechanisms by which beneficial microbes sustain or boost growth under these conditions remain unclear.
• What they did: The study tested how Enterobacter sp. SA187 promotes Arabidopsis thaliana growth in elevated CO2, focusing on ethylene-dependent signaling and measuring plant gene expression and primary metabolism changes.
• The result: Growth enhancement is linked to ethylene-dependent signaling and a deep reprogramming of plant gene expression and primary metabolism, supporting a mechanistic basis for microbe–CO2 benefits.
