By employing cyclamen young leaves, petioles and callus from Cyclamen persicum as explants, transformation of cucumber flowering integrator (CFL gene) into the genome of Cyclamen persicum mediated by Agrobacterium tumefaciens was conducted to compare the transformation efficiencies of different explants and to optimize the sonication-assisted transformation procedure mediated by Agrobacterium. The results demonstrated that the CFL gene was integrated into the genome of regenerated Cyclamen plants, which were validated by PCR and RT-PCR and by GUS histochemical assay. The results also showed that young leaves were the best receptor for transformation among employed explants, which the GUS-positive rates of regenerated plants can reach 27.25%. Furthermore, GUS positive rate can be increased four times by using the sonication-assisted transformation procedure. In this study, we successfully introduced the CFL gene into the genome of Cyclamen persicum by using modified high-efficiency genetic transformation system, which might be an alternative way for developing early flowering Cyclamen variety.
