| The genetically transformed roots of red beet have been shown, for the first time, to produce very high levels of peroxidase (POD; EC 1.11.1.7) accounting for 1.21 x 10(6) Units L-1. Of the ten clones established using different strains of Agrobacterium rhizogenes, one was that from the strain LMG-150, three each from A 2/83, A 20/83 and A4. All the clones showed true integration of T-DNA when tested by PCR and Southern hybridization methods. Each clone differed significantly from the others in growth, hormone dependency and POD production where LMG-150 produced highest biomass (140 g FW L-1) as well as POD (ranging from 8000-9000 U g-1 FW and 1.18 x 10(6) U L-1 with a specific activity of 600 U mg-1 protein) on hormone-free medium, both in shake-flask as... |
