Fig. 8. Altered
-tubulin localization in unc mutant spermatocytes.
(A) Unc-GFP (green) and anti-
-tubulin (blue) labeling cysts at multiple
stages of development in a wild-type testis. DNA is labeled with propidium
iodide (red). Boxes, enlarged below, include cells entering meiosis I (1) and
exiting meiosis II (2). (B,C)
-Tubulin labeling in wild-type (B)and
unc mutant (C) spermatocytes. In mutants,
-tubulin staining is
reduced to small dots, each probably equivalent to a pair of centrioles in
wild type. Scale bars: 10 µm.
