"Effects of exposure ot various red lights upon subsequent dark adaptation measured by the method of constant stimuli .JOSA 1955, 45, 502-506.
Upon red light excitation, only PhotoPr generates Lumi-R photoproduct, which then proceeds through Meta-Ra and Meta-Rc intermediates before forming the Pfr state.
In the presence of the chromophore phycocyanobilin (PCB), PhyB binds to phytochrome PIF3 and forms a heterodimer upon red light (∼650 nm) illumination.
Soon enough, a stranger approaches McCoy and says that the widgets are actually white but are illuminated by red lights… Upon seeing this conversation, another stranger who seems to McCoy to be a factory employee tells McCoy not to listen to the other stranger: he is a trickster, McCoy is told, who likes to mess around with visitors.
Your heart races when you come upon a long red light and all you see is burned out buildings and church and bar-b-que hovels.
The photosensitizer MB is known to kill P. aeruginosa in vitro upon activation by red light at concentrations of about 100 μM (equivalent to 0.003%), while immune cells are largely spared by this treatment49.
Upon exposure to red light, the light-sensing protein Cph8 induces the expression of cI and luxI: CI represses the expression of lacZ in the same cell regardless of AHL concentration while LuxI triggers the production of AHL that can diffuse to neighboring cells in the dark region to induce the production of LacZ.
Upon illumination with red light, Pr is converted to the active far-red absorbing form, Pfr, which can be transformed back to Pr by far-red light.
Finally, the optogenetic toolkit has been recently expanded by a light-activated phosphodiesterase (LAPD) that hydrolyses cyclic nucleotides upon stimulation by red light (Gasser et al., 2014).
Upon illumination with red light, the photosensitizer molecule linked to the second biotinylated Ab15 liberates singlet oxygen that cleaves any neighboring thioether bonds, thus releasing VeraTag™ reporters in close proximity.
