| Abstract/Description: | The enzyme 1-aminocyclopropane-1-carboxylate deaminase converts ACC, the precursor of the plant hormone ethylene to α-ketobutyrate and ammonium. The enzyme has been identified in few soil bacteria, and is proposed to play a key role in plant growth promotion. In this study, the isolates of plant growth promoting rhizobacteria were screened for ACC deaminase activity based on their ability to grow on ACC as a sole nitrogen source. The selected isolates showed the presence of other plant growth promoting characteristics such as IAA production, phosphate solubilization and siderophore production. The role of ACC deaminase in lowering ethylene production under cadmium stress condition was also studied by measuring in vitro ethylene evolution by wheat seedlings treated with ACC deaminase positive isolates. Nucleic acid hybridization confirmed the presence of ACC deaminase gene (acdS) in the bacterial isolates. |
