The fer-4 rhizosphere microbiome promotes plant growth and alleviates LP stress. Arabidopsis seeds were germinated on 1/2-strength MS media for 3 days and then transplanted to either HP or LP media for another 5 days. The seedlings were then transferred to vermiculite and inoculated with Col-0 or fer-4 rhizosphere microbiomes. (B), Images were taken 4 weeks after inoculation. Data information: All experiments were repeated three times with similar results.
