Fig. 6. Expression of the 19S-RP subunit S1 and P-Cyclin E in the Drosophila germarium. (A-C) 19S-S1 (red) localizes to the fusome (green, stained with Hts). Some fusomes are free of 19S-S1 staining (arrowhead). S1 is also accumulated in a granular manner in the rest of the germarium. (D-F) 19S-S1 expression in encore mutants is reduced; however, some S1 protein can still by observed in the mutant germarium. (G-I) In wild-type germaria, P-Cyclin E (red) localizes to the fusome (green). The expression is transient as some fusomes express some P-Cyclin E and others do not. (J-L) In encore mutant germaria, P-Cyclin E is more often observed localized to the fusome.
