Fig. 2. The fors allele results in a transport phenotype in
tubules. Fluid secretion assays were performed on intact tubules from
7-day-old adult forR and fors flies.
Basal rates of secretion were measured and capa-1 (10-7 mol
l-1) (Kean et al.,
2002) added at 30 min (arrow). Secretion rates were monitored for
a further 30 min. Fluid secretion rate (nl min-1) are means
± S.E.M. (N=8) for forR tubules
(broken line) and fors tubules (solid line).
*P<0.05, using t-tests on experimental
versus control at each time point separately.
