Visualisation of all stages of spermatogenesis in GGA knockdown testes. GGA was depleted ubiquitously using a Tubulin-Gal4 driver and testes squashes from male flies were compared with those from control flies. By phase contrast microscopy we observed no differences in the morphology of the stages of spermatogenesis in the GGA depleted testes. Note that all stages in spermatogenesis were visualised, culminating in individualised sperm. Bar, 20 μm.
