Summary Transgenic Phaseolus vulgaris or common bean has been produced using electric-discharge particle acceleration. The method uses particle acceleration to introduce DNA into bean seed meristems. Multiple shoots are then generated and screened to recover transgenic plants at a rate of 0.03% germline transformed plants/shoot. We have been able to recover transgenic plants using both GUS and herbicide screening to introduce the gus, bar, and bean golden mosaic virus coat protein genes into the navy bean cultivar, Seafarer. The transgenic plants have been characterized over 5 generations of self-fertilization with no loss of introduced genes or expression. In addition, several families have been crossed with non-transgenic parents and these plants also show expected inheritance patterns. The introduced bar gene has been shown to confer strong resistance in transgenic beans to basta herbicide application in the greenhouse.
