A. Mahn et al., TRANSIENT GENE-EXPRESSION IN SHOOT APICAL MERISTEMS OF SUGAR-BEET SEEDLINGS AFTER PARTICLE BOMBARDMENT, Journal of Experimental Botany, 46(291), 1995, pp. 1625-1628
Sugarbeet apices were used as targets for particle bombardment with a
microtargeting device. Before examining gene expression, particle pene
tration experiments were carried out. Transient GUS expression was det
ected within the first and second cell layers of the meristem. Dividin
g cells with GUS activity demonstrated that cells survived the bombard
ment procedure.
