TAFII110 and TAFII60 are required for Dorsal-dependent transcriptional activation of twist and snail in the early embryos. In situ hybridizations of mid-stage five embryos by using snail (A–H) or twist (I–L) antisense RNA probe are shown. Embryos from dl/+ (A, E, and I), dl/+; TAFII110ΔC/+ (B, F, and J), dl/+; TAFII110ΔB/+ (C, G, and K), or dl/+; TAFII60YY/+ (D, H, and L) females that are mated with either wild-type males (A, B, C, D, E, and I), TAFII110ΔC/P[Kr-lacZ] males (F and J), TAFII110ΔB/P[Kr-lacZ] males (G and K), or TAFII60YY/P[Kr-lacZ] males (H and L) are shown.
