RT-PCR screen for Gr RNAs expressed in Gr5a-positive GRNs. (A) Examination of Gr5a and Gr66a RT-PCR products in flies expressing UAS-PABP under control of the Gr5a-GAL4 or Gr66a-GAL4. The RNAs were prepared from the labella of flies containing the UAS-PABP transgene only and from Gr5a-GAL4;UAS-PABP and Gr66a-GAL4;UAS-PABP flies. elav was used as an internal control. The arrows and arrowheads indicate the products generated from the reverse-transcribed mRNA and from the genomic DNA templates, respectively. The sizes of DNA markers (kb) are indicated to the left. (B) RT-PCR products for Gr64b, Gr33a, Gr39aD, Gr59f, Gr22e, Gr32a, Gr63a, and Gr98a. No RT-PCR products for Gr63a or Gr98a were detected. (C) RT-PCR products for the Gr-S group (Gr64 cluster genes and Gr61a).
