Fig. 1. RNA in situ hybridisation reveals comet and cup transcript patterns. (A) Drosophila testis viewed by phase contrast. Asterisk, apical tip; bracket, spermatocytes; arrowheads, early spermatids; arrows, elongating spermatid bundles. (B-D) Control genes. (E,F) Typical cup and comet localisation. Scale bar: 100 µm for to A-F. (G-J) Typical cup localisation at spermatid distal ends. Scale bar: 25 µm. (K) Diagram of a spermatid bundle showing the location of comet and cup transcripts relative to spermatid nuclei, and cyst cells (grey).
