AgrobacteriumMediatedMaizeTransformation:ImmatureEmbryosVersusCallus
Transformation with Agrobacterium tumefaciens is the preferred method for delivery of transgenes into a wide range of plant species including maize. Optimized protocols for the Agrobacterium -mediated transformation of freshly isolated immature embryos and embryogenic Type I callus derived from plant seedlings are described. These protocols are suitable for the transformation of a wide variety of corn genot......阅读全文
