1922 Jrnl. Soc. Dyers & Colourists 38 8/1 The green pigment chlorophyll has been shown by Willstätter to be an equilibrium mixture of chlorophyll A and chlorophyll B... This equilibrium is not appreciably altered when photo-assimilation of CO2 is taking place.
1963 D. Mazia & A. Tyler Gen. Physiol. of Cell Specialization i. 17 An early study of the stoichiometry of acetate utilization in certain bacterial photosyntheses was not accepted as a demonstration of a reductive photoassimilation of this carbon source.
1975 Nature 9 Oct. 490/2 No photoassimilation was observed in the absence of sulphide or light.
1999 Crop Sci. (Nexis) 1 Nov. 1733 Mechanisms of transport and photoassimilation must be considered in studies of heat stress, but perhaps equally important is the effect of high temperature on starch biosynthesis.
