身体颜色在鱼类生态中起着重要作用,主要是通过两个原理产生的:a)吸收与反射入射光的色素颜色和b)散射、折射、衍射和干涉的结构颜色。变温动物,尤其是鱼类,有几种细胞类型,即所谓的色素体,它们采用上述两种原理中的一种。它们一起产生了动态的、多色的图案,用于交流和伪装。几种染色质类型具有可移动的细胞器,使其能够快速改变颜色。最近,我们描述了许多海洋鱼类的红色荧光,并认为它可能在没有红色的环境中用于私人通信。在这里,我们描述了在鱼类中发现的一种染色质,它调节了皮肤部分荧光色素的分布。这些细胞呈树突状,含有可运动的荧光颗粒。我们通过实验证明,荧光粒子可以通过激素和神经控制聚集或分散。这是脊椎动物细胞中稳定和自然的细胞骨架相关荧光控制机制的第一次描述。它的神经控制支持了荧光可以作为一些海洋鱼类的环境依赖信号的建议,并鼓励在这一领域的进一步研究。荧光物质在不同的化学条件下是稳定的,在强的、恒定的照明下没有明显的漂白。
Body coloration plays a major role in fish ecology and is predominantly generated using two principles: a) absorbance combined with reflection of the incoming light in pigment colors and b) scatter, refraction, diffraction and interference in structural colors. Poikilotherms, and especially fishes possess several cell types, so-called chromatophores, which employ either of these principles. Together, they generate the dynamic, multi-color patterns used in communication and camouflage. Several chromatophore types possess motile organelles, which enable rapid changes in coloration. Recently, we described red fluorescence in a number of marine fish and argued that it may be used for private communication in an environment devoid of red. Here, we describe the discovery of a chromatophore in fishes that regulates the distribution of fluorescent pigments in parts of the skin. These cells have a dendritic shape and contain motile fluorescent particles. We show experimentally that the fluorescent particles can be aggregated or dispersed through hormonal and nervous control. This is the first description of a stable and natural cytoskeleton-related fluorescence control mechanism in vertebrate cells. Its nervous control supports suggestions that fluorescence could act as a context-dependent signal in some marine fish species and encourages further research in this field. The fluorescent substance is stable under different chemical conditions and shows no discernible bleaching under strong, constant illumination.
