- Аннотация: The effect of dibromothymoquinone on chlorophyll fluorescence was studied in Chlamydomonas reinhardtii cells using PAM and PEA fluorometers. Dibromothymoquinone was shown to affect differently control cells incubated in complete medium and S-starved cells. The fluorescence yield in the control suspension considerably increased in the presence of the inhibitor. Presumably, this can be due to inactivation of protein kinase, as a result of which part of light-harvesting complex II that could have diffused from the stacking zone of the membrane into the lamellar zone towards photosystem I remains close to photosystem II. In S-starved cells, whose photosynthetic apparatus is in state 2, the fluorescence level declines in the presence of dibromothymoquinone. The JIP testing of induction curves (O-J-I-P fluorescence transient) suggests that dibromothymoquinone inhibits both light-harvesting complex II kinase and photosynthetic electron transport when added to the control, while in the starved cells it acts predominantly as an electron acceptor.
