    Plant Cell Physiol 55:1216-23. 2014
    ..I also discuss the current views on the role of (1)O2 as a signaling molecule and the distance it might be able to travel within cells. ..

    Alison Telfer
    Division of Molecular Biosciences, Imperial College London, South Kensington Campus, London, UK SW7 2AZ
    Photochem Photobiol Sci 4:950-6. 2005
    ..The relevance of a cycle of electrons around photosystem II, via cytochrome b(559), in order to re-reduce the beta-carotenes when they are oxidised and hence restore their ability to quench singlet oxygen, is also discussed...

    Alison Telfer
    Wolfson Laboratories, Department of Biological Sciences, Imperial College of Science, Technology and Medicine, London SW7 2AY, UK
    Philos Trans R Soc Lond B Biol Sci 357:1431-39; discussion 1439-40, 1469-70. 2002
    ..One beta-carotene can mediate cyclic electron transfer via cytochrome b559. The other is probably destroyed upon oxidation, which might trigger a breakdown of the polypeptide that binds the cofactors that carry out charge separation...

    Alison Telfer
    Wolfson Laboratories, Department of Biological Sciences, Imperial College of Science, Technology and Medicine, London SW7 2AY, UK
    Biochemistry 42:1008-15. 2003
    ..Although contributions of chlorophyll cations cannot be formally ruled out, our results demonstrate that these spectra mainly arise from the cation radical species of the two carotenoids present in photosystem II reaction centers...

    Min Chen
    School of Biological Sciences, University of Sydney, NSW 2006, Australia
    Photochem Photobiol Sci 4:1060-4. 2005
    ..We conclude that PS II, in A. marina, utilizes Chl d and not Chl a as primary electron donor and that the primary electron acceptor is one of two molecules of pheophytin a...
