ABSTRACT

Plants produce a wide range of organic compounds like sugars, organic acids and vitamins, which can be used as nutrients or signals by microbial populations. On the other hand, microorganisms release phytohormones, enzymes, which may act directly or indirectly to activate plant immunity and regulate plant growth. Plant signalling molecules such as auxin and cytokinin can be produced by microorganisms to colonize efficiently with roots and enhance root activity. The isolated microbe Bacillus aryabhattai, has the ability to produce1-aminocyclopropane-1-carboxylate (ACC) deaminase to lower plant ethylene level, often a result of various stresses, and is found to be a key component in the efficacious functioning of this bacterium. The optimal functioning of this bacterium includes the synergistic interaction between ACC deaminase, and plant with bacterial indole-3-acetic acid (IAA).
