Summary
Crown galls were obtained from a monosomic addition plant of beet, carrying an extra chromosome of Beta procumbens, after transformation with a wild-type Agrobacterium tumefaciens strain. Analysis of peroxidase and esterase patterns obtained after cellulose acetate gel electrophoresis and iso-electric focusing respectively, gave evidence that no preferential loss of the alien chromosome on repeated subculture in-vitro from the crown galls occurred.
