Genetic diversity of ACC-deaminase positive bacteria in Colorado soil under winter wheat cultivars (Triticum aestivum L.)
MetadataShow full item record
ACC-deaminase positive bacteria (ACC+) promote plant growth and development by lowering abiotic stress ethylene levels through deamination of 1-aminocyclopropane-1-carboxylic acid (ACC), the immediate precursor of ethylene. During drought stress, ACC+ bacteria can help plants better tolerate drought stress in arid and semi-arid areas such as Colorado. The purpose of this study was to assess the capability of ACC+ bacteria to support winter wheat cultivar growth and production under drought stress conditions. In a field study, the relative abundance and genetic diversity of ACC+ bacteria associated ...
