Fig. 2. ofs identifies a distinct pathway controlling spermatocyte
development. (A,B) Immunofluorescent images of frozen split
squashes. Aly staining (red) is indistinguishable between heterozygotes (A)
and homozygotes (B). (A) Cyclin A (green) is predominantly cytoplasmic in
heterozygous spermatocytes. (B) In the mutants, Cyclin A accumulates in nuclei
(arrows) relatively close to the apical tip.
