[Features of lettuce transgenic plants with ifn-alpha2b gene regenerated after Agrobacterium rhizogenes-mediated transformation].

"Hairy" roots of lettuce Lactuca sativa and regenerated plants with interferon-alpha2b gene had been obtained via Agrobacterium rhizogenes-mediated transformation. According to the results of PCR and rt-PCR analyses the studied plants had ifn-alpha2b gene. The regenerated plants differed from the plants of wild type by elongated internodes, early flower-bearing stem formation and purple coloration of leaves in artificial illumination conditions.
