cyanosome

A tissue-specific, membrane-bounded cytoplasmic organelle within which an unknown blue pigment is localized. Cyanosomes are synthesized in cyanophores and are blue in appearance.

response to high fluence blue light stimulus by blue high-fluence system

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of the detection of a high fluence blue light stimulus by the blue high-fluence system. Blue light is electromagnetic radiation with a wavelength of between 440 and 500nm. The blue high-fluence system responds to blue light at levels between 100 and 1000 micromols/m2.

response to low fluence blue light stimulus by blue low-fluence system

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of the detection of a low fluence blue light stimulus by the blue low-fluence system. Blue light is electromagnetic radiation with a wavelength of between 440 and 500nm. The blue low-fluence system responds to blue light at or below 0.1 micromols/m2. In certain species excitation of the blue low fluence system induces the transcription of a number of nuclear and plastid coded genes.

obsolete hemocyanin

OBSOLETE. A blue, copper-containing oxygen carrier present in many molluscs and arthropods.

regulation of anion channel activity by blue light

Any process in which blue light modulates the frequency, rate or extent of anion channel activity.

UV-A, blue light phototransduction

The sequence of reactions within a cell required to convert absorbed photons from UV-A or blue light into a molecular signal; the UV-A, blue light range is defined as having a wavelength within the range of 315 to 400 nm.

cellular response to blue light

Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a blue light stimulus. Blue light is electromagnetic radiation with a wavelength of between 440 and 500nm.

response to blue light

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a blue light stimulus. Blue light is electromagnetic radiation with a wavelength of between 440 and 500nm.

obsolete negative regulation of anion channel activity by blue light

OBSOLETE. Any process in which blue light stops, prevents, or reduces the frequency, rate, or extent of the anion channel activity.

blue light signaling pathway

The series of molecular signals initiated upon sensing of blue light by photoreceptor molecule, at a wavelength between 400nm and 470nm.
