Action Spectra for Chromatic Adaptation in Tolypothrix tenuis.
The dark synthesis of biliproteins in the blue-green alga Tolypothrix tenuis is controlled by brief light treatments. Green light potentiates synthesis of phycoerythrin and red light potentiates synthesis of phycocyanin. Red reverses the effect of green and vice versa. Action spectra for the red and green effects were obtained for the wavelength region 320 nanometers to 710 nanometers, at 10-na...
متن کاملChromatic Adaptation Model for Incomplete Chromatic Adaptation
When the adaptation level is not high enough, the maximum adaptation stimulus is not equal with the plot of illuminant. This property is accepted in this paper. Using this property, we propose a chromatic adaptation model for the level of adapting luminance and chromaticity in various surrounding illuminants. In this model, we calculate the maximum adapting responses using adapting degree for v...
متن کاملDark and photometabolism of sugars by a blue green alga: Tolypothrix tenuis.
The carbohydrate metabolism of the autotrophically grown blue-green alga, Tolypothrix tenuis, was studied. The alga respires glucose, fructose, galactose, and ribose. About 60% of the glucose consumed is converted by starved cells into a glucose polysaccharide. Glucose uptake and O(2) consumption are not inhibited by 0.01 m arsenite or by 0.005 m iodoacetamide. The distribution of (14)C in the ...
متن کاملComputing chromatic adaptation
Most of today’s chromatic adaptation transforms (CATs) are based on a modified form of the von Kries chromatic adaptation model, which states that chromatic adaptation is an independent gain regulation of the three photoreceptors in the human visual system. However, modern CATs apply the scaling not in cone space, but use “sharper” sensors, i.e. sensors that have a narrower shape than cones. Th...
متن کاملAction Spectra and Adaptation Properties of Carp Photoreceptors
The mass photoreceptor response of the isolated carp retina was studied after immersing the tissue in aspartate-Ringer solution. Two electro-retinogram components were isolated by differential depth recording: a fast cornea-negative wave, arising in the receptor layer, and a slow, cornea-negative wave arising at some level proximal to the photoreceptors. Only the fast component was investigated...
