Detection of Ri T-DNA in transformed oilseed rape regenerated from hairy roots

Abstract
A fertile plant with altered phenotype of oilseed rape (Brassica napus) spring cultivar HM-81 was regenerated from hairy root tumors incited by Agrobacterium rhizogenes 15834. Southern blot hybridization analysis revealed several copies of Tl and Tr-DNA of Ri plasmid.
