Abstract
Oilseed rape is considered relatively recalcitrant for genetic modification. This work was performed to establish conditions for effective transformation and regeneration of commercially used cultivars Campino, Haydn, Heros, Hunter and Topas (Brassica napus L.). Cotyledonary petioles and hypocotyls (obtained from the seedlings grown under dark conditions) as a source of explants were used. Our experiments revealed that a lower selection pressure in combination with postponing of selection by 14 days after co-cultivation resulted in recovery of transgenic plants from all cultivars. Transformants were obtained with efficiency from 1 to 5.5%. Histochemically GUS-positive plants were analysed by PCR using primers corresponding to the internal fragments of gus and nptII genes. The transgenic nature was confirmed by Southern blot analyses using a specific nptII probe. This work enriches the list of oilseed rape cultivars available for genetic modification.
