Fig. 7. Differential expression of daf-16 isoforms. Intron and exon structures of the daf-16a and daf-16b isoforms are depicted. Pink boxes correspond to coding sequences and gray boxes are 5' or 3' untranslated regions. Light blue lines with inward facing arrows represent predicted amplified PCR products that are on the microarray. The corresponding expression profile for each PCR product is depicted. Columns represent different times during the timecourse except the first column (D/L1) which is the ratio of dauer to L1 at 0 hours. Scale shows level of expression.
