Flash-induced Pchlide photoreduction in 6-day-old etiolated wheat leaves.

A) Native PAGE of SOD isoforms in M fragments of leaves: E—etiolated, EFD—etiolated and then illuminated with a single flash followed by incubation in darkness for 30 minutes; The pooled sample was used for electrophoresis; each well was loaded with 25 μg of protein B) The distribution of the relative activity of SOD isoforms in M leaf fragments; the data represents the mean ± SD, n = 3 (** p < 0.01; *** p < 0.001); C) Fluorescence emission spectra measured at 77 K for M fragments of laves; Excitation 440 nm.
