Sugarbeet apices were used as targets for particle bombardment with a microtargeting device. Before examining gene expression, particle penetration experiments were carried out. Transient GUS expression was detected within the first and second cell layers of the meristem. Dividing cells with GUS activity demonstrated that cells survived the bombardment procedure.
Key words: Beta vulgaris, direct gene transfer, microtargeting, particle bombardment, shoot apical meristem
