Emergent bacterial community properties induce enhanced drought tolerance in Arabidopsis

Abstract Drought severely restricts plant production and global warming is further increasing drought stress for crops. Much information reveals the ability of individual microbes affecting plant stress tolerance. However, the effects of emergent bacterial community properties on plant drought toler...
