Abstract
Optimized conditions for Agrobacterium-mediated lisianthus pollen transformation were adjusted using various factors such as temperature, pH and sucrose concentration. Pollen tube growth was successfully achieved in a medium (pollen germination medium; PGM) containing sucrose with pH in the range of 5.5-7.0 at temperature of . Lisianthus pollen was vacuum-infiltrated with Agrobacterium cell suspension for 20 min, and transformed pollen was confirmed by GUS histochemistry and Southern hybridization following RT-PCR. Transgenic pollen system may be utilized for establishing an area of plant transient expression systems based on the convenient pollen transformation procedure presented in here.
