Study on the Obtaining of Transgenic Wheat with GNA Alien Gene by Biolistic Particle

<正> The immature embryos of wheat plants, cv. Jing 411, 12 - 14 days after pollination, were cultured on SD2 medium for callus induction. After 10 days culture, 800 wheat calli were bombarded by biolistic particle coated with the DNA of plasmid pBI121-2 harboring both Galanthus nivalis agglutinin gene and bar gene. 67 green plants were finally regenerated from the bombardment calli on selection medium
