大豆[Glycine max（L.）梅尔。]与来自农杆菌属菌株CP 4的编码草甘膦耐受性5-烯醇式莽草酸-3-磷酸合酶的基因的杂交导致草甘膦耐受性品系40-3-2的发育。草甘膦（N-膦酰基甲基甘氨酸）是Roundup除草剂的活性成分。1992年在17个地点、1993年在23个地点和1994年在18个地点对40-3-2品系进行了产量试验。在这些地区，从早期营养生长到豆荚饱满，以不同的比例在40-3-2或其衍生物上喷洒草甘膦。在任何地点都没有观察到草甘膦处理导致的显著产量降低。抗草甘膦大豆的开发有望为农民提供一种新的杂草控制系统，该系统应在广泛的条件下降低生产成本和可靠的杂草控制。
Transformation of soybean [Glycine max (L.) Merr.] with a gene encoding a glyphosate-tolerance 5-enolpyruvylshikimate-3-phosphate synthase enzyme from Agrobacterium sp. strain CP4 resulted in the development of glyphosate-tolerant line 40-3-2. Glyphosate (N-phosphonomethyl glycine) is the active ingredient of Roundup herbicide. Line 40-3-2 was yield tested at 17 locations in 1992, 23 locations in 1993, and 18 locations in 1994. At those locations, broadcast applications of glyphosate at various rates were made over 40-3-2 or its derivatives from early vegetative growth to pod fill. No significant yield reduction was observed as a result of the glyphosate treatment at any of the locations. Development of glyphosate-tolerant soybean promises to provide the farmer with access to a new weed control system that should result in lower production costs and reliable weed control under a wide range of conditions.
