ban influences dendrite distribution over the body wall epithelium.
(A) Positively labeled homozygous mutant ban△1 epithelial clones (green) were generated in a heterozygous background. PNS dendrites are labeled by HRP immunoreactivity (magenta).
(B) Distribution of dendrites over the region directly below epithelial nuclei (denoted by asterisks) was monitored for wt or ban mutant clones. Instances in which PNS dendrites cross this region are color-coded magenta and instances in which this region is devoid of dendrites are color-coded green. Note that dendrites cross this domain in a higher proportion of ban mutant epithelial cells than in neighboring heterozygous cells.
(C) Quantification of dendrite growth into the domain shadowed by the epithelial nucleus of control (Frt 2A) or ban mutant epithelial clones. Average number of events per 100 clones of each genotype is shown. n > 500 cells for each genotype.
