Science (New York, N.Y.)
|March 16, 1979
Resumen
Nueve especies de mariposas poseen una novedosa rodopsina de larga longitud de onda que absorbe a 610 nanómetros, el más largo conocido entre los invertebrados. Otras especies tienen rodopsina que absorbe el verde, lo que indica diversas adaptaciones de pigmento visual en las mariposas.
Área de la Ciencia:
- * Entomología.
- * Fisiología visual.
- * Biología Molecular.
Sus antecedentes:
- * Las mariposas exhiben diversas capacidades visuales.
- * Comprender la visión de las mariposas requiere caracterizar sus pigmentos visuales, particularmente las rodopsinas.
Objetivo del estudio:
- * Para investigar la sensibilidad espectral y la absorción de rodopsina de varias especies de mariposas.
- * Identificar nuevos pigmentos visuales y su distribución en diferentes especies.
Principales métodos:
- * Se realizaron experimentos fotoquímicos y fisiológicos no invasivos en mariposas intactas.
- * Se midió la sensibilidad espectral y la absorción máxima de las rodopsinas.
Principales resultados:
- * Nueve de las 17 especies de mariposas poseen una rodopsina que absorbe al máximo a 610 nm.
- * Este pigmento visual de 610 nm es la longitud de onda más larga conocida para cualquier invertebrado.
- * Todas las especies estudiadas también tienen rodopsina absorbiendo al máximo en el espectro verde.
- * Ocho especies carecen de la rodopsina de 610 nm.
Conclusiones:
- * Las mariposas exhiben una gama más amplia de espectros de absorción de pigmentos visuales de lo que se conocía anteriormente.
- * El descubrimiento de una rodopsina de 610 nm en algunas especies sugiere adaptaciones a entornos de luz o señalización específicos.
- * Se necesita más investigación para comprender las implicaciones ecológicas y evolutivas de estos diversos pigmentos visuales.

01:20Anatomy of the Eyeball
The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle layer, the vascular tunic,...
01:22Photoreceptors and Visual Pathways
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category, whereas...
01:11Channel Rhodopsins
Most organisms use photoreceptors to sense and respond to light. Examples of photoreceptors include bacteriorhodopsins and bacteriophytochromes in some bacteria, phytochromes in plants, and rhodopsins in the photoreceptor cells of the vertebral retina. The light-sensitive property of these receptors is because of the bound chromophores, such as bilin in the phytochromes and retinal in the rhodopsins.
Rhodopsins belong to the family of cell surface proteins called G-protein coupled receptors,...

01:29The Photochemical Reaction Center
Reaction centers are pigment-protein complexes that initiate energy conversion from photons to chemical entities. Therefore, photochemical reaction center is a more appropriate term that describes these complexes. The Nobel laureates Robert Emerson and William Arnold provided the first experimental evidence of photochemical reaction centers by demonstrating the participation of nearly 2,500 chlorophyll molecules for the release of just one molecule of oxygen. Despite thousands of photosynthetic...
01:32The Retina
The retina is a layer of nervous tissue at the back of the eye that transduces light into neural signals. This process, called phototransduction, is carried out by rod and cone photoreceptor cells in the back of the retina.
01:24Color Vision
Color perception begins in the retina, the light-sensitive layer at the back of the eye. Two main theories explain how colors are seen: the trichromatic theory and the opponent-process theory. The trichromatic theory, proposed by Thomas Young in 1802 and extended by Hermann von Helmholtz in 1852, suggests that color vision is based on three types of cone receptors in the retina. These cones are sensitive to different but overlapping ranges of wavelengths corresponding to red, blue, and green.
