Název v původním jazyce
A dip in the chlorophyll fluorescence induction at 0.22 s in Trebouxia-possessing lichens reflects a fast reoxidation of photosystem I. A comparison with higher plants
Popis výsledku v původním jazyce
An unusual dip (compared to higher plant behaviour under comparable light conditions) in chlorophyll fluorescence induction (FI) at about 0.22 s was observed for thalli of several lichen species having Trebouxia species (the most common symbiotic green algae) as their native photobionts and for Trebouxia species cultured separately in nutrient solution. This dip appears after the usual O(J)IP transient at a wide range of excitation light intensities (1001800 mol photons m 2 s 1). Simultaneous measurements of FI and 820-nm transmission kinetics (I820) with lichen thalli showed that the decreasing part of the fluorescence dip (0.20.4 s) is accompanied by a decrease of I820, i.e., by a reoxidation of electron carriers at photosystem I (PSI), while the subsequent increasing part (0.42 s) of the dip is not paralleled by the change in I820. These results were compared with that measured with pea leaves representatives of higher plants. In pea, PSI started to reoxidize after 2-s excitation. T
