Fig. 3. Comet and cup transcription precedes the histone-protamine switch.
Bars above graphs and colours within graphs indicate H2A-mRFP (histone, red)
and Mst35Ba-EGFP (protamine, green; overlap orange/yellow) detection.
(A-C) Control Q-RT-PCRs. (D-J) Comet and cup Q-RT-PCR expression
profiles show that expression initiates in cysts negative for protamine.
(K) Nuclear fluorescence in elongating cysts.
