Fig. S9.

Germbands of axn RNAi embryos undergo limited AP axis elongation compared with WT. Shown are snapshots of live imaging of WT and axn RNAi Tribolium embryos during germband stage (Movie S4). As clear from the overlay of early (green) and late (red) time points, WT germband experiences substantial growth along the AP axis. On the other hand, axn RNAi germbands experience little or no growth in the AP direction. Note that, in the axn RNAi embryo shown, the embryo slides dorsally (upward) inside the egg. In all embryos shown, anterior is to the left, and dorsal is up.
