Genetic engineering and regeneration of Phaseolus and Vigna. State of the art and new attempts

The various methods and experiments of generic transformation and regeneration of the important pulses belonging to the legume genera Phaseolus and Vigna are reviewed. As the literature of these topics is widely dispersed in different journals, some of which are not easily available, details are given on the genotypes studied, and the media and hormones used. The results obtained so far are described, and some new attempts made in our laboratory are shown. The problems in legume biotechnology and some future aims are briefly discussed.
