Biolistics (gene-gun) is suitable for
  1. disarming pathogen vectors
  2. transformation of plant cells
  3. constructing recombinant DNA by joining with vectors
  4. DNA fingerprinting

Solution

In biolistic or gene gun method 1-2 $\mu \mathrm{g}$ tungeston or gold particle (called microprojectile) coated with DNA to be used for transformation are accelerated to velocities which enable their entry into plant cells/nuclei. This technique has general applicability to plant species and can be used to deliver DNA into virtually all tissues.
