FlyBase curator comment: this entry represents a transgenic construct where the particular construct used cannot be determined.
In individuals expressing Pih1D1VDRC.cUa under the control of Scer\GAL4VP16.bam, testes lack motile sperm and, although sperm bundles are largely normal, axonemes show loss of dynein arms, occasional microtubule occlusions and axonemal fragmentation.
In individuals expressing Pih1D1VDRC.cUa under the control of Scer\GAL4sca.PU, Ch neurons have a grossly normal cilium morphology despite of the absence of dynein arms.
