High and low pressure gene gun devices give similar transformation efficiencies in maize calluses

July 2010

  Maize (Zea mays) is a major food crop of the world. Biotechnology plays an important role in plant genetic improvement, particularly for the introduction of novel traits in order to improve agronomic performance, medical and industrial applications and food quality. Particle bombardment is a rapid and simple method that enables the generation of events and affords genes expression studies. Nonetheless, an...
