FIG. 6.

Northern blot analysis of RNA from transgenic plants containing the βC1 gene of TYLCCNV-Y10 DNAβ. Aliquots (40 μg) of plant total RNA extracted from transgenic leaf tissue of individual plants were loaded onto a 1.2% agarose gel containing formaldehyde. The blot was probed with a radiolabeled βC1 gene fragment. The ethidium bromide-stained gel shown below the blot indicates equal loading of RNA. The source plants were severely abnormal (SA), moderately abnormal (A), or symptomless (N). The arrow marks the location of βC1 mRNA.
