Features of ROS production in the ОЕ of P. knerii in the control group and after prolonged periodic odorant stimulation. (А‒C) A fragment of the OE in the control fish (А, blue and red channels; В, red channel); (C) the profile in Fig. A; the cytochemical reaction products were distributed as a fine substance. (D‒F) A fragment of the ОЕ in the experimental fish (D, blue and red channels, E, red channel); (F) the profile in Fig. D, E; the cytochemical reaction products, except for the fine substances, mostly formed large clusters (indicated by arrows). Staining for ROS (CellROX deep red reagent, red) and nuclei (DAPI, blue); confocal microscopy, 3D reconstructions. (G) The volume occupied by the fluorescent signal of ROS in the control group (1) and after prolonged odorant chemostimulation (2). The graph shows the data obtained by the quantitative analysis of the Z-stacks; confocal microscopy). *pu ≤ 0.05 compared with the control group. Scale bars: A‒F, 30 mkm.
