Supplementary Fig. S2.

Posterior defects in pair-rule gene expression persist during and after gastrulation. This figure shows wild-type ((A) and (C)) and tll^g embryos ((B) and (D)) stained for Eve and Odd protein at Bownes’ stage 6 (gastrulation; (A) and (B)) and stage 10 or older (extended germ-band; (C) and (D)). Antibody stains are shown for Eve (red) and Odd (green). Persistent patterning defects and missing stripes are observed at the posterior end of the germ-band in tll mutant embryos ((B) and (D)). Stripe numbers are indicated for clarity.
