Cover legend

This montage image shows the morphology of an asexual pea aphid ovariole. The germarium, oocyte, and early embryos were stained with a cross-reacting antibody against the Drosophila Nanos protein, which is a germline marker. Localized Nanos signals (green) were identified in presumptive germ cells in the posterior area of the blastoderm, suggesting that other localized signals in earlier stages reveal the position of germ plasm. Nuclei were stained with DAPI (blue) and F-actin was stained with phalloidin (red). For further details, see the article by Chang et al pp 413-421 in the present issue.
