Chlorophyll fluorescence: a probe of photosynthesis in vivo.

Annual Review of Plant Biology, 2008
The use of chlorophyll fluorescence to monitor photosynthetic performance in algae and plants is now widespread. This review examines how fluorescence parameters can be used to evaluate changes in photosystem II (PSII) photochemistry, linear electron ...

Chlorophyll-chlorophyll and chlorophyll-water interactions in the solid state

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1972
Abstract Absorption spectra in the visible and infrared have been recorded for films of dry chlorophyll a , chlorophyll b , bacteriochlorophyll, pyrochlorophyll a , and pheophytin a . The effects of water on the spectra have also been studied.

The Chlorophyll Story [PDF]

AJN, American Journal of Nursing, 1955
keeps things outdoors a beautiful green, is one of the most unravelled mysteries of the organic world. We are just scratching the surface of a partial understanding of its properties and the values it may hold when it is used properly. Chlorophyll is the catalyst that converts moisture, carbon dioxide, and the sun's energy-by some means-into the ...

Chlorophyll synthetase in chlorophyll-free chromoplasts

Plant Cell Reports, 1981
A considerable incorporation of [1-(14)C]isopentenyl diphosphate into chlorophyll in chromoplast preparations from daffodil flowers (Narcissus pseudonarcissus L.) was observed when exogenous chlorophyllide a was added. The enzyme chlorophyll synthetase showed properties of a peripheral membrane protein.

Organization of chlorophyll biosynthesis and insertion of chlorophyll into the chlorophyll-binding proteins in chloroplasts

Photosynthesis Research, 2015
Oxygenic photosynthesis requires chlorophyll (Chl) for the absorption of light energy, and charge separation in the reaction center of photosystem I and II, to feed electrons into the photosynthetic electron transfer chain. Chl is bound to different Chl-binding proteins assembled in the core complexes of the two photosystems and their peripheral light ...

A method for the extraction of chlorophyll from leaf tissue without maceration

, 1979
A simple, rapid method requiring few manipulations for the extraction of chlorophylls from fragmented leaf tissue of angiosperms and gymnosperms is compared with the widely used acetone method.

Biosynthesis of Chlorophyll a in a Purple Bacterial Phototroph and Assembly into a Plant Chlorophyll-Protein Complex.

ACS Synthetic Biology, 2016
Improvements to photosynthetic efficiency could be achieved by manipulating pigment biosynthetic pathways of photosynthetic organisms in order to increase the spectral coverage for light absorption.
