Abstract
Results of persistent spectral hole burning (PSHB) experiments in fluo rescence spectra of Fe-limited and Fe-replete cells of D. tertiolecta are reported. Low temperature fluorescence spectra exhibit an increase of PS II fluorescence of Fe-limited cells due to a decrease of an eff iciency of excitation energy transfer (EET) in PS II. A 1.5 nm blue sh ift of PS II fluorescence maximum observed for Fe-limited cells is the result of excessive light harvesting complexes LHCII in thylakoid mem brane. The PSHB experiments revealed an influence of Fe stress on EET from and between core antenna proteins CP43 and CP47. EET within core antenna proteins CP43 and CP47 is not affected by iron limitation.
