Photosynthesis powers
nearly all life on Earth. The absorption of sunlight by pigments in photosystems
drives photosynthesis. Land plants are exposed to strongly fluctuating light
conditions. Not only the light intensity, but also the light spectrum can
rapidly change during the day. As plants are sessile they cannot run away from
unfavourable light conditions . Instead they have to optimize their
photosynthetic light-harvesting machinery and make the best of it. In this talk
I will show how confocal microscopy, fluorescence lifetime imaging and
time-resolved fluorescence can be used to reveal how plants adapt their
thylakoid membrane when illuminated with different colours of light.
