Chromatophore tissue density and skeletal density banding as a measure of the adaptive response of healthy corals to environmental change
Chromatophores, pigment-bearing cells within the ectodermal layer of hermatypic scleractinian coral tissues, are postulated to enhance the photosynthetic activity of zooxanthellae symbionts and possibly protect the coral animal from harmful ultraviolet (UV) radiation. Yet connections have not …

Quantitative tracking of the cellular and skeletal response of the Caribbean coral Orbicella annularis to gradients in marine sewage pollution
… of the density of zooxanthellae and chromatophore cells within the coral tissues. X-ray computed tomography (BioCT) was used to determine the density of the outermost layer of the coral skeletal being precipitated at the time of sampling in May 2014. Results indicate that …

Cell-Cycle Specific Biosynthesis of the Photosynthetic Membrane of Rhodopseudomonas Sphaeroides: Structural Implications
Fusion of chromatophores, the photosynthetic membrane vesicle isolated from the intracytoplasmic membranes (ICM) of the photosynthetic bacterium Rhodopseudomonas sphaeroides, was achieved by the use of polyethylene glycol as fusogen. Ultracentrifugation, electron microscopy (EM), intrinsic density …

Computational investigation of light harvesting in purple photosynthetic bacteria
… reconciling multiple competing processes in the chromatophore. The first step in photosynthesis is the capture and transport of light energy in the form of short-lived electronic excitation called excitons. Rapid long-range exciton transport is key to the high light harvesting efficiency …

Computational investigations into two biological processes: membrane reshaping by light-harvesting proteins in the chromatophores of purple bacteria, and oligomerization and pore formation by the Hepatitis C viroporin p7
… (1) the light-harvesting proteins in the chromatophores of purple photosynthetic bacteria, and (2) the structure and function of the Hepatitis C viroporin p7. Purple photosynthetic bacteria form membranous pseudo-organelles called chromatophores which house the photosynthetic machinery. …

Isolation and Identification of the Abnormal Opaque material in the White Mutant of Siamese Fighting Fish, Betta Splendens
… a metabolic malfunction or as a purine-pteridine chromatophore inter-relationship. Guanine gout may result when a lack of xanthine dehydrogenase or guanase prevents guanine destruction to normal by-products. Alternately, increased enzyme activity by guanine deaminase may produce excess guanine …

Structure and Assembly of the Photosynthetic Membrane of Rhodobacter Sphaeroides
… centers incorporated into liposomes, or intact chromatophore membranes were cross-linked. The complexes were composed of H-M, H-L, H-M-L, or L-M. The cross-linking of cytochrome c to soluble or membrane bound reaction centers was observed using any of the four cross-linking reagents. The …

Carbon cycling in the Caribbean reef-building coral Orbicella: quantitative evidence for enzymatic control of skeletal density banding and coral-endosymbiont physiological plasticity during seasonal environmental change
… expression of a versatile ectodermal cell, the chromatophore, specifically and plastically, to facilitate or inhibit light-capture by the coral’s photosynthetic endosymbiont, the unicellular dinoflagellate zooxanthellae. Quantitative image analyses show that both the cellular density of …
