自然光环境对许多原核生物很重要。最明显的是，光养原核生物需要使它们的光合装置适应主要的光照条件，并且这种适应通常辅以运动性，以使细胞能够重新定位以寻找更有利的光照条件。非光养原核生物也可能会寻求避免具有破坏性的强度和波长的光，并且许多具有不同生活方式的原核生物可能会利用光信号作为有关周围环境的丰富信息源以及适应环境和行为的提示。在这里，我们讨论目前对细菌感知光照强度、波长和方向的方式的理解，以及将光感知与运动行为控制联系起来的信号转导网络。我们讨论了原核生物尺度的光感知问题，以及小细菌细胞中定向光感知的挑战。我们解释了蓝细菌、紫色光合细菌、化能异养细菌和盐古菌等原核生物光控运动系统的特性和共同特征。作者讨论了我们对原核生物如何控制其运动以响应光照强度、光谱质量和方向的理解。
The natural light environment is important to many prokaryotes. Most obviously, phototrophic prokaryotes need to acclimate their photosynthetic apparatus to the prevailing light conditions, and such acclimation is frequently complemented by motility to enable cells to relocate in search of more favorable illumination conditions. Non-phototrophic prokaryotes may also seek to avoid light at damaging intensities and wavelengths, and many prokaryotes with diverse lifestyles could potentially exploit light signals as a rich source of information about their surroundings and a cue for acclimation and behavior. Here we discuss our current understanding of the ways in which bacteria can perceive the intensity, wavelength and direction of illumination, and the signal transduction networks that link light perception to the control of motile behavior. We discuss the problems of light perception at the prokaryotic scale, and the challenge of directional light perception in small bacterial cells. We explain the peculiarities and the common features of light-controlled motility systems in prokaryotes as diverse as cyanobacteria, purple photosynthetic bacteria, chemoheterotrophic bacteria and haloarchaea. The authors discuss our understanding of the ways in which prokaryotes can control their motility in response to the intensity, spectral quality and direction of illumination.
