Abstract

Transgenic broccoli (Brassica oleracea var. italica) was produced by two Agrobacterium tumefaciens-mediated transformation methods. One used flowering stalk explants from mature plants; the other used hypocotyl and petiole explants from in vitro-grown seedlings. Several hundred transformants containing a Bacillus thuringiensis ∂-endotoxin gene (CryIA(c)-type) and the neomycin phosphotransferase gene were recovered. Rooted transformants were obtained in as little as 3 months using seedling explants. Transgenic cabbage was also obtained by the seedling explant method. Parameters important for high efficiency regeneration and transformation rates included use of a tobacco nurse cell layer, sealing of petri dishes with a porous surgical tape instead of Parafilm, preculture of seedling explants and appropriate length of co-cultivation with Agrobacterium. Advantages and disadvantages of each transformation procedure are discussed.
