Stress control and acc deaminase

Abstract

During its lifetime, a plant is subject to a wide range of both biotic and abiotic stresses that can limit the growth and development of the plant. The one thing that all of these stresses have in common is that they induce the plant to synthesize growth-inhibiting stress ethylene. Plants that are treated with plant growth-promoting bacteria that synthesize the enzyme 1-aminocyclopropane-1-carboxylate (ACC) deaminase produce lower levels of stress ethylene as a consequence of the consumption of the ethylene precursor ACC by the enzyme. These treated plants are damaged/inhibited to a significantly lesser extent following a biotic or abiotic stress than are plants that are not treated with ACC deaminase-containing plant growth-promoting bacteria.
