Fly division

S Tumps in animal cells (reviewed by Rappaport, 1986; Satterwhite and Pollard, 1992; Fishkind and Wang, 1995) provide a view of cytokinesis whereby in each dividing cell, a contractile ring of interdigitated anti-parallel actin and bipolar myosin (nonmuscle myosin II) filaments forms in the equatorial region of the cell cortex, and then constricts, in purse string-like fashion, to pinch the cel...

Influx into Fly Photoreceptors

Ion-selective calcium microelectrodes were inserted into the compound eyes of the wild-type sheep blowfly Lucilia or into the retina of the no steady state (ms) mutant of Lucilia. These electrodes monitored light-induced changes in the extracellular concentration of calcium (A[Ca2+]o) together with the extracellularly recorded receptor potential. Prolonged dim lights induced a steady reduction ...
