Dear Photosynthesis Net Readers:
Dr. Adam Gilmore and I, at the address given below, plan to
submit a "minireview" to Physiologia Plantarum on the mechanistic aspects
of xanthophyll-cycle dependent non-radiative energy dissipation in higher
plants and algae.
In this minireview, we are particularly interested in including data and
discussion on:
(1) Ultrafast (femtoseconds to picoseconds) time-resolved absorption
spectroscopy pertaining to the xanthophyll cycle pigments or related
carotenoids in vitro (or in vivo, if available).
(2) Ultrafast (picoseconds to nanoseconds) time-resolved
fluorescence analysis related to quenching of fluorescence by
xanthophyll-cycle pigments or to "photoinhibition" processes.
(3) Fluorescence analysis of Light-harvesting Chl a/Chl b complex
II (LHC-II)- deficient mutants especially with relation to xanthophyll-
dependent quenching of Chl a fluorescence.
(4) Fluorescence and/or pigment analysis of mutations affecting
the minor CP (chlorophyll proteins) of the PSII inner antenna (labeled as
CP-24,CP-26,and CP-29).
[We would also like to get in touch with anyone who is making or
planning to make mutants on these complexes, if none are available yet.]
(5) Analysis of xanthophyll-cycle dependent quenching of
fluorescence and of xanthophyll-dependent chloroplast ATPase activity at
low physiological temperatures.
Would you be kind enough to send us, by first class or by air mail, your
reprints, preprints and papers in preparation on this or related topic?
Any comments on these topics will also be appreciated? Would you also
please let us know of any work of others that you may be aware of in
these areas?
We would be delighted to share with you a copy of our
"minireview" when ready, if you would please include your name and
address in your mailing to us.
If you would like to see what we have done this year in this
area, you may please look at the following paper:A. Gilmore,T.L. Hazlett
and Govindjee "Xanthophyll cycle dependent quenching of photosystem II
chlorophyll a fluorescence: Formation of a quenching complex with a short
fluorescence lifetime" Proc Natl Acad Sci USA 92,pp. 2273-2277 (March, 1995).
With kind regards, and, with appreciation in anticipation of your
forthcoming help,
Adam Gilmore and Govindjee
