[Show abstract][Hide abstract] ABSTRACT: Data from the literature on the ability of microorganisms to form plant hormones have been reviewed. The substances covered include abscisic acid, ethylene and other compounds with phytohormone-like properties (brassinosteroids, oligosaccharines) and analogues of animal neurotransmitters (biogenic amines). Pathways whereby the substances are metabolized and their effects on the development and activity (physiological and biochemical) of the microorganisms are considered. The role of phytohormones and hormone-like substances in the formation of association (microorganism-host) interactions are analyzed. The potential utilities of microorganisms producing hormones and hormone-like substances are discussed.

[Show abstract][Hide abstract] ABSTRACT: The ability of pro- and eukaryotic microorganisms to synthesize growth-stimulating phytohormones is reviewed, with emphasis on pathways of biosynthesis of these compounds and their effects on physiological and biochemical properties of the producers. Phytohormones are viewed as specific mediators in interactions between various organisms inhabiting the same ecological niche, the biological role of which is not limited to processes taking place in plants. In addition to setting forth theoretical aspects of this problem, the review underscores the need to utilize such producer microorganisms in plant cultivation and biotechnology.
