Developmental-stage-, sex-, and caste-specific expression of a subset of yellow and mrjp genes. Shown are data from yellow-f, yellow-g, and yellow-h, and also mrjp-1, mrjp-3, and mrjp5. RT-PCR products were run on gels for visualization of gene expression. The primers are listed in Supplemental Table S3. The expression of mrjp5 was examined by Northern blotting using a PCR-amplified insert of a cDNA clone as a probe (nucleotides 15–1942 of NM_001011599). See Methods for more details.
