In this paper, G418-resistant regenerated plants were obtained from hypocotyl segments which had cocultivated with Agrobacterium tumefaciens LBA4404 (p35SGUSINT) via adventitious bud regeneration. DNA/DNA dot hybridization and GUS histochendcal assay revealed that the foreign GUS gene from Agrobacterium tumefaciens LBA4404 had been integrated into genome of Antirrhinum mains and expressed in the cells.
