Abstract

The lipid-soluble paramagnetic probe I (12,3) undergoes partially reversible photo-induced redox conversion on interaction with the electron-transport chain of the chloroplast. The incorporation of I (12,3) into the chloroplast membrane does not influence the kinetic characteristics of the EPR I signal (from P700+). The parameters of the EPR spectrum from I (12,3) do not change on illumination though they are sensitive to temperature and different additives (Mg2+, ATP, atabrin).
