Fig. 1. Hr39 mutants alter spermathecal and parovarial development. (A) The female lower reproductive tract (RT). (B) Hr39 transcript structure showing the four different isoforms with insertion mutations indicted above. (C-G) Nomarski images of RT. All RT images possess a single seminal receptacle (asterisk). (C) Wild-type RT with two spermathecae and two parovaria (one out of focus). (D) Hr3903508 RT with no spermatheca or parovarium. (E,F) Magnifications of parovaria (circled); (E) wild type, (F) Hr3904443. (G) Hr3904443 RT with three spermathecae and two parovaria. (H) Percentage of homozygous females of each genotype possessing 0, 1, 2 or 3 spermathecae. Arrows, spermathecae; arrowheads, parovaria; asterisks, seminal receptacles. Scale bar: 100 µm in C,D,G.
