— A new chlorophyll, designated chlorophyll RCI (Chi RCI), with absorption and fluorescence properties different to other known chlorophylls, has been extracted from photosystem I (PSI) sub-chloroplast particles of the green alga Scenedesmus obliquus; it was suggested that this chlorophyll is either...
III. Influence on cell division of Chlorella Vanadium, although essential for growth and chlorophyll formation in unicellular green algae, reveals toxic influences on cell division of Chlorella pyrenoidosa, these disturbances arising in the same range of V-concentrations as the kno...

There were no significant differences in energy quenching between treatments, except at 35 °C, which showed decreased photochemical quenching and increased non-regulated non-photochemical quenching. Chlorophyll a and chlorophyll c at 15 °C and 35 °C exhibited lower amounts at the end of ...
In plants, isoprenoids occur in theessential oils, which are found in the gummy exudates (oleoresins and latices) of many trees and shrubs. Plant isoprenoids effect growth (e.g., the hormonegibberellic acid) and contribute to red, yellow, and orange pigments (carotenoids).Chlorophyll, the gr...
and an emeritus professor of the University of Cambridge. He was the first to determine the full structure of chlorophyll (in 1967) and was involved in the development of the synthesis of vitamin B12 by Robert Burns Woodward. He has made major contributions to the use of organosilicon compounds...
interest to note that no instance has ever been reported of the occurrence of the green photosynthetic biochrome, chlorophyll, in the absence of carotenoids, whereas the reverse condition is very common, in that countless bacteria and fungi synthesize one or more members of the series of ...
