Manganese Toxicity to Chlorophyll Synthesis in Tobacco Callus [PDF]
Plant Physiology, 1986 Tobacco (Nicotiana tabacum) pith explants were grown on manganese containing medium. At moderate concentration (10 millimolar), manganese selectively inhibited chlorophyll synthesis, resulting initially in growth of white callus. Several weeks later the white callus turned brown due to the accumulation of a pigment identified as protoporphyrin IX by ...

Design, synthesis and properties of synthetic chlorophyll proteins [PDF]
European Journal of Biochemistry, 2001 A chemoselective method is described for coupling chlorophyll derivatives with an aldehyde group to synthetic peptides or proteins modified with an aminoxyacetyl group at the ε‐amino group of a lysine residue. Three template‐assembled antiparallel four‐helix bundles were synthesized for the ligation of one or two chlorophylls.

The effect of oxytetracycline and florfenicol antibiotics on growth, chlorophyll a and total protein to microalgae Chaetoceros muelleri (Lemmermann, 1898) [PDF]
بومشناسی آبزیان, 2023 The study aimed to examine the chronic toxicity effects of oxytetracycline (OTC) and florfenicol (FLO) antibiotics, commonly used in shrimp farms, on the growth performance, chlorophyll a content, and total protein of Chaetoceros muelleri microalgae.

A spatial analysis of physiological changes associated with infection of cotyledons of marrow plants with cucumber mosaic virus [PDF]
, 1996 Changes in host primary metabolism associated with the compatible interaction between cucumber mosaic virus and cotyledons of the marrow plant (Cucurbita pepo L.) have been localized, first by measuring activities of key enzymes in infected and ...

Chlorophyll Synthesis in Dark-Grown Pine Primary Needles [PDF]
Plant Physiology, 1998 Abstract The pigment content of dark-grown primary needles of Pinus jeffreyi L. and Pinus sylvestris L. was determined by high-performance liquid chromatography. The state of protochlorophyllide a and of chlorophylls during dark growth were analyzed by in situ 77 K fluorescence spectroscopy.

Mechanism Underlying the Shading-Induced Chlorophyll Accumulation in Tea Leaves
Frontiers in Plant Science, 2021 Besides aroma and taste, the color of dry tea leaves, tea infusion, and infused tea leaves is also an important index for tea quality. Shading can significantly increase the chlorophyll content of tea leaves, leading to enhanced tea leaf coloration ...

ZZE-Configuration of chromophore ß-153 in C-phycocyanin from Mastigocladus laminosus [PDF]
, 1987 The photochemistry of C-phycocyanin has been studied after denaturation in the dark. It shows an irreversible reaction which has characteristics of a Ζ,Ζ,Ε- to Z,Z,Z-isomerization of dihydrobilins. Its amplitude depends on the reaction conditions, with
