aura mutant embryos fail to recruit germ plasm to the furrows. (A-B′) vasa RNA localizes to the furrow in wild type (A,A′) but not in aura mutants (B,B′), where it instead localizes to the blastodisc periphery (B, bracket). Arrows indicate cleavage planes for the first and second cell cycles. Boxed regions in A,B are shown in A′,B′. Scale bar: 100 μm in A,B; 50 μm in A′,B′.
