Apoptosis on wild-type (mwh/flr) wing discs induced by irradiation with UVB using four fluorescent lamps (peak at 312 nm). (A) The number of AO-stained clusters induced by irradiation at 0 kJ/m² (open triangles), 0.15 kJ/m² (closed triangles), 1 kJ/m² (open diamonds), 2.5 kJ/m² (closed diamonds), 5 kJ/m² (open circles), and 10 kJ/m² (closed circles). (B) and (C) The UV-dose dependency of apoptosis at 6 h post-exposure (B) and 12 h post-exposure (C). Apoptosis is shown as the number of clusters stained by AO. The values of R² were obtained by a linear approximation method
