ACC Deaminase Producing Microorganisms in Stress Agriculture: From Hypothesis to Omics
Microbial 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase (EC 18.104.22.168) is an intracellular enzyme that is known to be associated with ethylene signaling in plants. Ethylene, despite being an important gaseous phytohormone in plants, is overproduced as a response to environmental stresses. Fortunately, certain beneficial microorganisms, especially bacteria and fungi, assist plants in regulating ethylene homeostasis in plants. They possess the ACC deaminase enzyme that cleaves ACC, the immediate precursor of ethylene into α-ketobutyrate and ammonia. To perform this action, they generally have to establish a close association with plants either as endophytes or reside around the rhizosphere or rhizoplane regions. Studies on plant–microbe interaction under various biotic and abiotic stresses have opened different arenas regarding the role of microbial ACC deaminase as part of synergistic interactions. This Topic will particularly focus on ACC-deaminase-producing microorganisms, their role in stress alleviation, application in agriculture, molecular studies on mechanistic insights, as well as genetic engineering and omics approaches.
