Chromatophores of Rhodospirillum rubrum

Nature, 1952
THE pigments of pbiotosynthetic bacteria are not localized in chloroplasts, and appear upon microscopic examination to be evenly distributed throughout the cell. It has long been known that the absorption maxima of the bacteriochlorophyll and carotenoid pigments are markedly shifted following extraction with organic solvents—a fact first interpreted by

Chromatophore Effect of Adrenocorticotrophic Hormone

Nature, 1954
ADRENOCORTICOTROPHIC hormone preparations produce an effect1 similar to and even more pronounced than that of the pituitary chromatophore hormone intermedine2. When either of these hormones is injected into pale frogs, the melanophores ‘expand’ and the skin darkens. The identity of the two hormones has been assumed3 but contested4. In the frog, however,

CHROMATOPHORES

Biological Reviews, 1930
Summary.Chromatophores, the parts concerned with the colour changes in animals, are best developed in the cephalopods, the crustaceans, and the three lower classes of vertebrates, the fishes, amphibians, and reptiles. In the cephalopods chromato‐ phores are really diminutive organs in that each one consists of a central coloured cell which is expanded ...

Ultrastructure of cephalopod chromatophore organs

Zeitschrift f�r Zellforschung und Mikroskopische Anatomie, 1968
The chromatophore organs of Loligo opalescens are composed of five different types of cells: the chromatophore proper; radial muscle fibers; neuronal processes (axons); glial cells; and chromatophoral sheath cells. The surface of a retracted chromatophore is extensively folded, but upon contraction of the radial muscle fibers it becomes flattened and ...
