Fig. 7. Phenotypic analysis of heron and kali. (A) Larval MB neuroblast clones homozygous for hrn² results in process extension from the calyx (long arrow). (B) Dendritic overextension persists in hrn clones when examined in adult (long arrow). Nod-ßgal is distributed in a subset of overextending processes. (C,D) Neuroblast clones homozygous for kali¹ extend processes in all directions from the calyx that are positive for Nod-ßgal (long arrows). (D) A partial confocal z-stack that removed axonal lobes overlapping the overextended dendrites in the x-y plane.
