Aldo-keto Reductase Metabolizes Glyphosate and Confers Glyphosate Resistance in Echinochloa colona.

abstract：:The 7S seed storage protein (beta-conglycinin) of soybean (Glycine max [L]. Merr.) has three major subunits; alpha, alpha', and beta. Accumulation of the beta-subunit, but not the alpha- and alpha'-subunits, has been shown to be repressed by exogenously applied methionine to the immature cotyledon culture system (LP H...
