Figure S5.
Major spermatocyte defects are observed within testes from pUbq-Cnn-CT flies.
(A and B) Fluorescence images showing spermatocytes at different developmental stages (as indicated) from flies expressing either pUbq-Cnn-C (A) or pUbq-Cnn-CT (B) fixed and stained for microtubules (green, α-tubulin), centrosomes (pink, asterless), and DNA (blue). A high density of cytosolic microtubules, as well as cytokinesis and karyokinesis defects, are clearly observed in cells from pUbq-Cnn-CT testes.
