[Genetic transformation of sugar beet: evolution of theoretical and experimental approaches].

The review is dedicated to several aspects of sugar beet (Beta vulgaris L.) biotechnology: in vitro cultivation, callus induction, plant regeneration and genetic transformation. Media composition, methods of plant regeneration via somatic embryogenesis and protoplast culture are analysed. The use of Agrobacterium tumefaciens and gold particle bombardment is the base for modern genetic transformation methods.
