Figure 2. H3K9me2 Accumulation on Extrachromosomal, Multicopy Transgenes Is Defective in ego-1 but Not in dcr-1 Mutants.

Figure 2

Each panel shows a portion of the meiotic germline from a strain carrying the repetitive extrachromosomal array, ex7291.

(A) ex7291 is visible in DAPI-stained preparations of both ego-1/+ and ego-1 tissue (see insets; arrows indicate extrachromosomal array). A bright focus of H3K9me2 staining, corresponding to ex7291, is visible in ego-1/+ (arrows) but not ego-1 tissue.

(B) A bright focus of H3K9me2 staining, corresponding to ex7291, is visible in both dcr-1/+ and dcr-1 tissue. Scale bar equals 20 μm; inset scale bar equals 5 μm.
