Abstract

Plant growth-promoting bacteria are soil bacteria that are involved in a beneficial association with plants; these bacteria use a variety of mechanisms to facilitate plant growth. The major mechanisms used by plant growth-promoting bacteria include the functioning of the enzyme 1-aminocyclopropane-l-carboxylate (ACC) deaminase which cleaves the compound ACC, the immediate precursor of the phytohormone ethylene in all higher plants, and synthesis of the plant hormone indoleacetic acid (IAA). Plant growth-promoting bacterial strains that contain ACC deaminase and produce IAA provide a wide range of different plant species with a significant level of protection from the damage caused by various environmental stresses including heavy metals and the presence of organic environmental contaminants. Here we discuss how bacterial ACC deaminase and IAA work synergistically to facilitate plant growth during the phytoremediation of metals and/or organics.
