Abstract. A simple and inexpensive system for the generation of fertile, transgenic maize plants has been developed. Cells from embryogenic maize suspension cultures were transformed using silicon carbide whiskers to deliver plasmid DNA carrying the bacterial bar and uidA (gus) genes. Transformed cells were selected on medium containing the herbicide bialaphos.
generated plants. Segregation data for the progeny of several transformants are also presented. This repre- sents the first report of transgenic plant production, in any species, with the silicon carbide whisker-mediated trans- formation approach. Results Transient GUS expression in regenerable maize cells
Silicon carbide is – after diamond and boron carbide – the third-hardest mineral in the world.
