This study was conducted to obtain the transformed tobacco (Nicotiana tubacum) plants with cytosolic ascorbate peroxidase gene(ApxSC7) using Agrobacterium tumefaciens LBA4404. A cDNA encoding the cytosolic ascorbate peroxidase of strawberry, ApxSC7, was introduced into tobacco plants via Agrobacterium-mediated gene transfer system. The expression vector, pIG-AP8, harboring ApxSC7 gene was used for production of transgenic tobacco plants. A large number of transgenic plants were regenerated on a medium containing hygromycin. Integration of ApxSC7 gene was confirmed by PCR and Southern blot analyses with genomic DNA. Northern blot analyses revealed that the pIGap8 gene was constitutively expressed.
