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.

Mechanisms of biocontrol and plant growth-promoting activity in soil bacterial species of Bacillus and Pseudomonas: a review (2012, background): “Plants can tolerate diverse environmental stresses by the action of PGP bacteria producing the enzyme 1-aminocyclopropane-1-carboxylate (ACC) deaminase, which stimulate plant growth by decreasing plant ethylene levels (Glick 2005; Glick, Cheng, Czarny, and Duan 2007).”

Rhizosphere interactions: root exudates, microbes, and microbial communities1 (2014, methodology): “The plant hormone ethylene is involved in a multitude of plant responses particularly related to plant stress, and its production is regulated by light, temperature, nutrition gravity, and even the status and levels of other plant hormones (Glick 2005).”
