De Novo Shoot Bud Induction from the Catharanthus roseus Leaf Explants and Agrobacterium tumefaciens-Mediated Technique to Raise Transgenic Plants.

The regeneration of a whole plant from a single cell or organ explant was a valuable task for plant biotechnology. However, important medicinal plants such as Catharanthus roseus have shown recalcitrance to regeneration protocols, thus limiting investigations on MIA metabolism and metabolic engineering in this plant system. In this chapter, successful regeneration protocols were detailed for Catharanthus roseus, either by direct shoot bud induction from leaf explants and Agrobacterium-mediated genetic transformation.
