DEV01404 Supplementary Material

Files in this Data Supplement:

• Movie 1 -

  Movie 1. Dorsal view of dorsal branch migration and fusion in a control embryo. DB7, DB8 and DB9 are shown, of which DB9 is in the most advanced stage of migration. Genotype: btl-Gal4 UAS-gfp-moe/+. Recording started from stage 15 and elapsed time is indicated. Recording interval=1 minute. Anterior is leftwards.

• Movie 2 -

  Movie 2. Behavior of a terminal cell of DB6 placed in the A compartment. Genotype: btl-Gal4 UAS-gfp-moe/UAS-daxin. Lateral view; interval=3 min.

• Movie 3 -

  Movie 3. Effect of Ci^Act. Spreading behavior of a terminal branch is no longer limited to the P compartment. Genotype: btl-Gal4 UAS-gfp-moe/UAS- ci^Act. Dorsal view; interval=2 minutes.

• Movie 4 -

  Movie 4. Effect of Ci^R. Terminal cells extend additional terminal branches that are not restricted to the P compartment. Genotype: btl-Gal4 UAS-gfp-moe/UAS- ci^R.
