Soil microorganisms that produce the enzyme 1‐aminocyclopropane‐1‐carboxylate (ACC) deaminase promote plant growth by sequestering and cleaving plant‐produced ACC, and thereby lowering the level of ethylene in the plant. Decreased ethylene levels allows the plant to be more resistant to a wide variety of environmental stresses. Here, the biochemistry of ACC deaminase; the environmental distribution, regulation, evolution and expression of ACC deaminase genes; and information regarding the effect of this enzyme on different plants is documented and discussed.
