Expression of wdbEP3559 in the eye under the control of Scer\GAL4GMR.PF results in very mild defects in ommatidial organisation.
Expression of wdbEP3559 under the control of Scer\GAL4tim.PE lengthens the period of locomotor activity rhythms; the period is about 0.7 hours longer than that of controls. The lengthening of the period is dose-dependent; the period is increased by 1.5-2 hours if the temperature is increased to 29oC or two copies of wdbEP3559 are present. 5% of the flies are arrhythmic after about 4 days in constant darkness conditions.
Expression of wdbEP3559 under the control of Scer\GAL4ap-md544 results in many cells forming multiple wing hairs; an average of 49+/-20 cells in the fifth wing cell have a multiple wing hair phenotype.
Expression of wdbEP3559 under the control of Scer\GAL4sca-537.4 results in sensory organs with two sockets and two shafts, two sockets and one shaft, one socket and two shafts and dot-like socket morphology.
