A biolistic gene gun method also known as a microprojectile bombardment method is mainly used for the transformation of monocots, cereals and legumes that are typically recalcitrant to Agrobacterium-mediated transformation. This method of transformation involves accelerating DNA-coated gold or tungsten microparticles using gene gun. Bombardment has its own advantages and disadvantages. Among advantages are a relatively high efficiency, the ability to deliver DNA, the ability of delivering DNA without vector backbone, and the ability to deliver DNA to plastids. Drawbacks include substantial variations between experiments (due to differences in bullet preparation), integrations at multiple loci, frequent truncations of the transgene and substantial damage to bombarded tissue, and thus a lower regeneration capacity.
