To see the effect of SA190 on the growth of adult plants under drought conditions, 5 day-old non-colonized or SA190-colonized Arabidopsis were transferred to pots for 2 weeks.These results indicate that SA190 significantly enhances drought stress tolerance of Arabidopsis plants.To evaluate the agronomic potential of SA190 on crops, we performed growth chamber experiments with alfalfa which is used as an important animal feed in different regions of the world.SA190-inoculated alfalfa plants showed a 13% increase in biomass yield under continuous irrigation (Figs 11 and EV2).One week after re-watering, less than 50% of non-colonized plants resumed growth in comparison with a 100% of SA190-colonized plants (Fig 1G and H).

To see the effect of SA190 on the growth of adult plants under drought conditions, 5 day-old non-colonized or SA190-colonized Arabidopsis were transferred to pots for 2 weeks. Thereafter, watering was stopped, and plants were subjected to drought stress for 3 weeks. While non-colonized (Mock) plants showed a drop in survival by more than 70%, SA190-colonized plants were affected by less than 10% (Fig 1G and H). One week after re-watering, less than 50% of non-colonized plants resumed growth in comparison with a 100% of SA190-colonized plants (Fig 1G and H). These results indicate that SA190 significantly enhances drought stress tolerance of Arabidopsis plants.To evaluate the agronomic potential of SA190 on crops, we performed growth chamber experiments with alfalfa which is used as an important animal feed in different regions of the world. Alfalfa seeds were coated with SA190 and tested in parallel with mock-coated seeds in control growth chamber conditions. Randomized pot experiments with a drought protocol were performed in independent biological replicates. A control set of plants that was continuously watered for 52 days was used as controls. In parallel, for the drought experiment, plants were only watered for 42 days and then evaluated at day 52. SA190-inoculated alfalfa plants showed a 13% increase in biomass yield under continuous irrigation (Figs 11 and EV2). When the plants were exposed to 10 days without irrigation (drought stress), SA190-inoculated plants showed 37% higher biomass to the drought conditions compared with non-inoculated
