Effects of various pharmacological compounds on the light-induced loss of chemotaxis towards nitrite in pregametes of phototropin-reduced strain RNAi20. (A) Effect of staurosporine (), chelerythrine () or SC-9 () on the loss of chemotaxis in pregametes of RNAi20 that were shifted into white light at time 0; (B) Treatment with papaverine (), IBMX () or db-cAMP () on the loss of chemotaxis in pregametes of RNAi20 that were shifted into white light at time 0. Compounds were added to pregametes 10 min prior to start of illumination. The concentrations used were 1 μM for chelerythrine, 50 μM for papaverine, 50 μM for IBMX, 20 nM for staurosporine and and 200 μM for SC-9. Non-treated cells (●) were used as control. The fluence rate was 60 µmol m−2 s−1.
