Application of plant-growth-promoting rhizobacteria (PGPR) is an environmentally sustainable option to reduce the effects of abiotic and biotic stresses on plant growth and productivity. Bacteria isolated from rain-fed agriculture field soils in the Central Himalaya Kumaun region, India, were evaluated for the production of 1-aminocyclopropane-1-carboxylic acid (ACC)
deaminase
. Those producing ACC
deaminase
in high amounts were evaluated for their potential to improve wheat (
Triticum aestivum
L.) plant growth under irrigated and water-stress conditions in two glasshouse experiments. Some of the isolates also showed other plant-growth-promoting (PGP) traits, e.g., N
2
fixation, siderophore production, and phosphate solubilization; however, strains with higher ACC
deaminase
activity showed the greatest effects. These were
Variovorax paradoxus
RAA3;
Pseudomonas
spp. DPC12, DPB13, DPB15, DPB16;
Achromobacter
spp.
PSA7
, PSB8; and
Ochrobactrum anthropi
DPC9. In both simulated irrigated and water-stress conditions, a single inoculation of RAA3 and a consortium of DPC9 + DPB13 + DPB15 + DPB16 significantly improved wheat plant growth and foliar nutrient concentrations and caused significant positive changes in antioxidant properties compared with noninoculated plants especially under water stress. These findings imply that PGPB having ACC
deaminase
activity together with other PGP traits could potentially be effective inoculants to improve the growth of wheat plants in water-stressed rain-fed environments.
