Compound images taken at 24hpf (A,D,G,J), 48hpf (B,E,H,K), or 5dpf (C,F,I,L)
show examples of neural expression that is maintained at all ages (A–C), is
activated over time (D–F), is inactivated over time (G–I), or is only
present at one timepoint (J–L). Arrowheads mark spinal neurons (A–C, K),
lateral line neuromasts (E, F), and the eye (G–I). UAS reporters exhibit
transgene-specific variegation, leading to partially overlapping but distinct expression
patterns in a single animal (M–O). All images are lateral views. Scale bar: for
A–C is 250um, for D–I is 250um, for J–L is 250um, and for
M–O is 300um.
