A new photoreversible pigment has been isolated from the blue-green alga Tolypothrix tenuis. This pigment bears certain resemblances to phytochrome, except that absorption maxima for the two forms are in the green and red portions of the spectrum instead of the red and far-red. The pigment may control diverse differentiative processes in blue-green algae. 
Cultivation in the Dark of the Blue‐green Alga Fremyella diplosiphon. A Photoreversible Effect of Green and Red Light on Growth Rate
TLDR
The blue-green alga Fremyella diplosiphon Drouet can be grown in the dark on a medium consisting of mineral salts, glucose, and casein hydrolysate and the effect of green is reversible by brief irradiation with red light, and multiple photoreversibility was demonstrated.
Chromatic Adaptation of the Planktonic Blue-green Alga Oscillatoria redekei VAN GOOR and its Ecological Significance
TLDR
Cytophotometric and spectrophotometric determinations of the phycoerythrine and phycocyanine contents of different strains after exposure to blue-green and orange-red light suggested that chromatic adaptation of O. redekei takes place both at cellular and population level.
THE PHOTOREVERSIBLE NATURE OF A PIGMENT SYSTEM IN THE GREEN ALGA PROTOSIPHON BOTRYOIDES KLEBS*
TLDR
Recently, a protein pigment system was isolated from Protosiphon cells with absorption characteristics suggested by the action spectra obtained, and this system has absorption peaks in the blue and in the long-wavelength visible part of the spectrum, and a relationship between the system and control of zoospore formation in Protosphon is postulates.

1. Heterocysts are found in many species of filamentous blue‐green algae. They are cells of slightly larger size and with a more thickened wall than the vegetative cells.
PHOTOTRANSFORMATIONS OF PHYTOCHROME
TLDR
The molecular natures of the phototransformations are reviewed in relationship to knowledge of the chemistry of the chromophore and apoprotein and the significance of phytochrome intermediates in understanding the physiology of phYtochrome controlled responses is discussed.
Action Spectra for Chromatic Adaptation in Tolypothrix tenuis.
TLDR
Chromatic adaptation and another photomorphogenic response in the blue-green algae are discussed in terms of possible regulation by a photoreversible pigment recently isolated from Tolypothrix.
Chromatic adaptation in lichen phyco- and photobionts
TLDR
The effect of light quality on the photosynthetic pigments as chromatic adaptation in 8 species of lichens were examined and the total content of photosynthesis pigments was calculated according to the formule and particular pigments were determined by means CC, TLC, HPLC and IEC chromatography.

TLDR
The immunochemical aspects of the biliproteins were striking in that protein antigens from vastly different cell types were found to be closely related, and may be interpreted as supporting the suggestion that Rhodophyta evolved from Cyanophyta or from some common ancestral stock.
