RAD-51 Foci Perdure on Synapsed Autosomes and Unsynapsed X Chromosomes in Extended Early Pachytene
Three different nuclei from the extended early pachytene region of him-8 gonads are shown, one on each row. Immunofluorescence of SYP-1, HTP-3, and RAD-51 is shown in columns A, B, and C; DAPI counterstaining of chromosomes is shown in column D; the colors of each component in the merged image in column E are indicated by colored circles below (green, SYP-1; red, HTP-3; blue, RAD-51; DAPI staining is not shown in the merged image). Chromosomes containing HTP-3 but not SYP-1 are the unsynapsed X chromosomes (arrowheads). RAD-51 foci are visible on both the X chromosomes and the autosomes. Scale bar, 5 μm.
