Studies on the dependence of chlorophyll synthesis on protein synthesis in Euglena gracilis, together with a nomogram for determination of chlorophyll concentration

Planta, 1967
Experiments have been carried out to determine the basis for the dependence of chloroplast pigment synthesis on protein synthesis in dark-grown cells of Euglena gracilis greening in the light. The complete inhibition of chlorophyll synthesis brought about by actidione (10 μg/ml) when added half way through the greening process was not relieved, even to

Synthesis of chlorophyll-c derivatives by modifying natural chlorophyll-a

Photosynthesis Research, 2015
Chlorophyll-a (Chl-a) was extracted from cyanobacterial cells and modified to methyl pyropheophorbide-a. The 3-vinyl-chlorin was transformed to zinc complex of the corresponding 3-acetyl-porphyrin. The zinc porphyrin was oxidized to give cis-7,8- and 17,18-dihydroxy-chlorins as well cis-7,8-cis-17,18-tetrahydroxybacteriochlorin.

Regulation of chlorophyll synthesis in photosynthetic bacteria

Journal of Bioenergetics, 1973
Energy-transducing membranes of the nonsulfur purple photosynthetic bacteria are known to contain several species of bacteriochlorophyll (BChl) complexes. The reaction-centre complex (rc-BChl) is the locus of the charge separation that provides the “poles” of the photochemical electron transport system, whereas the other complexes serve lightharvesting

Chlorophyll synthesis by isolated intact etioplasts

Biochemical and Biophysical Research Communications, 1971
Abstract The light stimulated incorporation of label from 14C-labelled glycine and succinic acid into chlorophyll by isolated intact etioplasts indicates the presence of δ-amino-levulinic acid (δ-ALA) synthetase within the higher plant plastid.

Effect of lead ions on chlorophyll synthesis

Die Naturwissenschaften, 1974
Seeds of Avena sativa were grown in the dark in wet vermiculite at 22/sup 0/C. When the seedlings were 16 days old, the primary leaf was cut into pieces. These leaf pieces were put 25-ml Erlenmeyer flasks in 10 ml glycylglycine with and without PbCl/sub 2/, and preincubated in the dark for 1 h.
