Likewise, we know of no microspectrophotometry studies detailing the absorbance maxima of photopigments
in juvenile or adult Pacific halibut retinas.
This, taken together with evidence for extraocular photoreception in the nerve cords of decapods, warrants further investigation into whether the abundance of stomatopod opsin transcripts found in retinas extends to extraretinal tissues and whether they there form functional photopigments
that contribute to a significant physiological role.
Other structural changes are produced from a series of cross over events and result in a wide range of photopigments
with peak wavelength sensitivities between 560nm and 530nm.
These new indicators include such metrics as diagnostic photopigments
of algal functional groups to assess eutrophication (Paerl et al.
This trichromatic theory of vision assumes that people inherit a separate gene for each of the three photopigments
Both candidates seem to serve as apoproteins in photopigments
66-68) This has been attributed to the existence of a range of hybrid opsin genes which encode a range of photopigments
with different peak spectral sensitivities.
Opsin proteins, together with a light-sensitive chromophore, form photopigments
that are the basis of light detection in most animal extraocular and visual systems (Porter et al.
Further investigation into the spectral class(es) of planula photoreceptors, and the photopigments
responsible, is warranted.
An endoevaporitic microbial mat within a gypsum crust: zonation of phototrophs, photopigments
, and light penetration.
Knowledge of the spectral absorption characteristics of photopigments
for vertically migrating organisms and their relationship to the spectral availability of ambient light is critical to understanding the proximate physiological basis of DVM.
Maximum absorbance by photopigments
was determined by microspectrophotometry (MSP) or pigment extraction (PE).
