Abstract

The melanophores of a freshwater teleost, Zacco temmincki, responded to changes in illumination: in darkness the melanophores induced a melanosome aggregation and when subjected to light they caused a melanosome dispersion. 2. Using monochromatic light, the spectral sensitivity of the melanophores was examined. 3. The melanophores showed a different sensitivity to light between 400 and 600 nm with a maximum at about 525 nm. 4. The action spectrum closely resembled a porphyropsin absorbance curve, suggesting a porphyropsin or similar photopigment is active in the melanophore light response of Zacco temmincki.

摘要

淡水硬骨鱼马口鱼的黑素细胞对光照变化有反应：在黑暗中，黑素细胞会诱导黑素体聚集，而受到光照时则会导致黑素体分散。2. 使用单色光对黑素细胞的光谱敏感性进行了检测。3. 黑素细胞在400至600纳米之间对光表现出不同的敏感性，在约525纳米处达到最大值。4. 作用光谱与视紫蓝质吸收曲线非常相似,这表明视紫蓝质或类似的光色素在马口鱼黑素细胞的光反应中起作用。
