Gene expression profile of BAC T07M07 as determined by reverse Northern (gel-based RNA profiling). Following electrophoresis, DNA samples (see Fig. 2) were transferred onto a nylon membrane and the blot was hybridized to a single-stranded cDNA probe synthesized from wholeArabidopsis seedling poly(A) RNA. Hybridization signals indicate the presence of a transcript from the cloned region or gene region (with the caveat that transcripts from genes of similar sequence may also cross-hybridize). Dashed lines indicate the positions of predicted genes numbered above the line. Arrows indicate that the predicted gene extends to the next row. Small numbers mark the DNA sample in every tenth lane. New (N) indicates expression from regions not predicted to encode a gene. A Actin gene (A) used as an internal control for gene expression.
