Aldo-keto reductase metabolizes glyphosate and confers glyphosate resistance in Echinochloa colona

In this Plant Physiology paper, it is clearly established that glyphosate resistance in this Echinochloa population is due to an enhanced capacity to metabolise glyphosate, catalysed by an Aldo-keto reductase gene.  The first author on the paper is Dr Pan Lang, now at the Hunan Agricultural University, Changsha, China.
