Figure 4. Loss of snf and Mei-P26 results in mis-regulation of Nanos expression during cyst development.

(A) Control, (B) snf¹⁴⁸ homozygous and (C) mei-P26^mfs1 homozygous germaria stained for Nanos (green), Bam (red) and DNA (blue). Overlapping Nanos and Bam expression is readily observed in both mei-P26 and snf mutant ovaries. (D) A mei-P26^mfs1 clonal germarium stained for GFP (green) and Bam::HA (red). Both heterozygous cells (magenta arrow) and homozogous mei-P26 mutant clones (white arrow) appear to express similar levels of Bam::HA. Scale bars represent 10 µm.
