A NATO Advanced Study Institute on "Light as Energy Source and
Information Carrier in Plant Photo physiology" was held at
Volterra, Italy, from September 26 to October 6, 1994, in order to
consider the fundamental role that light plays in plant growth and
development. This book summarises the main lectures given at this
meeting which concentrated on both photochemical energy conversion
and signalling (photosensing) aspects. Light harvesting and
conversion into chemical energy in photosynthesis occurs at the
level of chlorophyll/carotenoid containing photosystems in plants.
Pigments are non covalently bound to a variety of polypeptides
which serve as a specific scaffolding, necessary to determine the
energy coupling between pigments and thus allowing rapid excitation
energy trasfer from the antenna to the special reaction centre
chlorophylls. Data from transient, time resolved spectroscopies, in
the femtosecond and picosecond domain, together with model
calculations, suggest that this process occurs in the 20-100
picosecond time span. The special ll u ture of reaction centre
complexes, ensures rapid primary charge separation, probably in the
order of 1-3 picoseconds, with subsequent charge stabilisation
reactions proceeding in the hundreds of picoseconds range. The
recently resolved crystallographic structure of LHCII, the
principal antenna complex of plants, allows precise determination
of pigment-pigment distances and thus permits calculation of
approximate chlorophyll-chlorophyll Forster hopping rates, which
are in good agreement with time resolved measurements."
