Chl -chlorophyll; Fm -maximum Chl a fluorescence; Fo -initial (minimal) Chl a fluorescence; Fv (= Fm -Fo) -variable Chl a fluorescence; I-step -Chl a fluorescence at ~ 30 ms; J-step -Chl a fluorescence at ~ 2 ms; OJIP curve -the 'fast' phase of the fluorescence transient ['O' is for the initial fluorescence (at ~ zero time), 'P' is for peak, and 'J' and 'I' are inflection points between 'O' and 'P']; PQ -plastoquinone; QA and QB -the first and second plastoquinone electron acceptor of PSII. Acknowledgments: We thank Zuzana Benedikty (of Photon Systems Instruments, The Czech Republic) for the generous gift of FluorPen to one of us (G. Govindjee). We are grateful to Roland Valcke for his suggestions to relate our observations to those on fluorescence imaging, which led to substantial improvement of our paper. We are highly thankful to Hartmut Lichtenthaler, the one who we are honoring here, for reading our paper, and for making crucial suggestions, before its submission. We are also grateful to the two anonymous reviewers for their very helpful comments. Conflict of interest: The authors declare that they have no conflict of interest.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
