Fig. 4. soti is required for normal individualisation complex
progression. Confocal maximum brightness projections of the entire cyst
depth. DNA is labelled with propidium iodide (A-D, magenta); actin is labelled
with FITC-phalloidin (A'-D', green). Scale bar: 10 µm.
(A-B'') In wild-type testes, investment cones assembled above
spermatid nuclei (A-A'') and moved along spermatid bundles as a complex
(B-B''). (C-D'') In soti mutant testes, investment
cones assembled normally, but complexes dissociated during
individualisation.
