Abstract

Lilium cv. Casablanca pollen grains stored at $-70^{\circ}C$ were grown in pollen germination medium with Agrobacterium tumefaciens LBA4404 cells harboring pBI121 for 18 hr at $27^{\circ}C$. Following this, cefotaxime (250 mg/L) was treated for 6 hr to eradicate the bacterial cells. Histochemical GUS analysis revealed that the transgenic pollen displayed deep blue color mostly from 12 hr after the co-cultivation. Presence of $200\;{\mu}M$ acetosyringone was determined not to be more effective for GUS transformation than its absence. GUS DNA integration in the transgenic pollen genomic DNA was clearly demonstrated by Southern blot analysis.
