Developing spermatids in the Drosophila testis. Ana1 (pink) and Sas-6 (cyan) mark basal bodies attached to individual spermatid nuclei (blue). Each basal body has a flagella (yellow) extending from its distal end. Galletta et al. show that the centriole protein Asterless regulates centriole length and basal body function.
