Avian visual pigments: characteristics, spectral tuning, and evolution.
Birds are highly visual animals with complex visual systems. In this article, we discuss the spectral characteristics and genetic mechanisms of the spectral tuning of avian visual pigments. The avian retina contains a single type of rod, four spectrally distinct types of single cone, and a single type of double cone photoreceptor. Only the single cones are thought to be involved in color discri...
متن کاملSpectral tuning of rhodopsin and visual cone pigments.
Retinal is the light-absorbing biochromophore responsible for the activation of vision pigments and light-driven ion pumps. Nature has evolved molecular tuning mechanisms that significantly shift the optical properties of the retinal pigments to enable their absorption of visible light. Using large-scale quantum chemical calculations at the density functional theory level combined with frozen d...
متن کاملEvolution and spectral tuning of visual pigments in birds and mammals.
Variation in the types and spectral characteristics of visual pigments is a common mechanism for the adaptation of the vertebrate visual system to prevailing light conditions. The extent of this diversity in mammals and birds is discussed in detail in this review, alongside an in-depth consideration of the molecular changes involved. In mammals, a nocturnal stage in early evolution is thought t...
متن کاملEvolution and Mechanism of Spectral Tuning of Blue-Absorbing Visual Pigments in Butterflies
The eyes of flower-visiting butterflies are often spectrally highly complex with multiple opsin genes generated by gene duplication, providing an interesting system for a comparative study of color vision. The Small White butterfly, Pieris rapae, has duplicated blue opsins, PrB and PrV, which are expressed in the blue (λ(max) = 453 nm) and violet receptors (λ(max) = 425 nm), respectively. To re...
متن کاملSpectral tuning and evolution of primate short-wavelength-sensitive visual pigments.
The peak sensitivities (λ(max)) of the short-wavelength-sensitive-1 (SWS1) pigments in mammals range from the ultraviolet (UV) (360-400 nm) to the violet (400-450 nm) regions of the spectrum. In most cases, a UV or violet peak is determined by the residue present at site 86, with Phe conferring UV sensitivity (UVS) and either Ser, Tyr or Val causing a shift to violet wavelengths. In primates, h...
