Fig. 5. The bristle phenotype of fry. All panels show fry6 homozygous animals. (A) Abdominal bristles from a pharate adult. Both split (arrowheads) and normal (arrows) looking bristles can be seen. Note that except for the location of the branchpoint the mutant bristles have a normal shape. (B) Several large bristles on the head of a pharate adult. These illustrate the abnormal shape seen in bristles in this region. (C) Part of the triple row from the anterior margin of the wing. Many of the stout bristles are split distally (arrowhead). (D) A confocal image of a phalloidin stained head bristle. This bristle has already started to break down actin filaments, which now appear as short segments. The bristle shows a branch (arrowhead) midway along its length. Note that actin filaments can be seen running from proximal to distal across the branch. (E) A bristle where the actin filaments become disorganized near the distal tip (arrow).
