FTIR study of primate color visual pigments
How do we distinguish colors? Humans possess three color pigments; red-, green-, and blue-sensitive proteins, which have maximum absorbance (λmax) at 560, 530, and 420 nm, respectively, and contribute to normal human trichromatic vision (RGB). Each color pigments consists of a different opsin protein bound to a common chromophore molecule, 11-cis-retinal, whereas different chromophore-protein i...
متن کاملDetection of Fruit and the Selection of Primate Visual Pigments for Color Vision
Primates have X chromosome genes for cone photopigments with sensitivity maxima from 535 to 562 nm. Old World monkeys and apes (catarrhines) and the New World (platyrrhine) genus Alouatta have separate genes for 535-nm (medium wavelength; M) and 562-nm (long wavelength; L) pigments. These pigments, together with a 425-nm (short wavelength) pigment, permit trichromatic color vision. Other platyr...
متن کاملPrimate photopigments and primate color vision.
The past 15 years have brought much progress in our understanding of several basic features of primate color vision. There has been particular success in cataloging the spectral properties of the cone photopigments found in retinas of a number of primate species and in elucidating the relationship between cone opsin genes and their photopigment products. Direct studies of color vision show that...
متن کاملModification of Flower Color Pigments and Color Composition with Hormonal Treatments and Sucrose in Tulipa gesneriana ‘Kingsblood’
Three separate experiments were conducted to investigate the interplay between three phytohormones and sucrose for the change of flower color composition and the plant secondary metabolites in Tulipa. The variations of the physiological and morphological characteristics, with ABA at 5 and 10 mg/L (as experiment one), GA3 at 300 and 500 mg/L (as experiment two), 50 and 10...
