Abstract |
Common bean Phaseolus vulgaris L. has been shown to be a recalcitrant plant to induce somatic embryogenesis (SE) under in vitro conditions. An alternative strategy to yield SE is based upon the use of a cytokinin (benzyladenine) coupled with osmotic stress adaptation instead of the auxin-inducing SE in common bean. Here we described the induction of proembryogenic masses (PEM) derived from the apical meristem and cotyledonary zone of zygotic embryos, from which secondary SE indirect embryogenesis emerged. Maturation of SE was achieved by using osmotic stress medium and converted to plants. Long-term recurrent SE was demonstrated by propagation of PEM at early stages of SE. This protocol is currently being applied for stable genetic transformation by means of Agrobacterium tumefaciens and biobalistics as well as basic biochemical and molecular biology research. |
