Chromatic acclimation (CA) encompasses a diverse set of molecular processes that involve the ability of cyanobacterial cells to sense ambient light colors and use this information to optimize photosynthetic light harvesting. The six known types of CA, which we propose naming CA1 through CA6, use a range of molecular mechanisms that likely evolved independently in distantly related lineages of the Cyanobacteria phylum. Together, these processes sense and respond to the majority of the photosynthetically relevant solar spectrum, suggesting that CA provides fitness advantages across a broad range of light color niches. The recent discoveries of several new CA types suggest that additional CA systems involving additional light colors and molecular mechanisms will be revealed in coming years. Here we provide a comprehensive overview of the currently known types of CA and summarize the molecular details that underpin CA regulation.

蓝细菌的色温适应：优化光合作用的多样且广泛的过程。

色温适应（CA）涵盖了一系列分子过程，这些过程涉及蓝细菌细胞感知环境光颜色并使用此信息优化光合光收集的能力。我们建议命名为CA1至CA6，这是六种已知类型的CA，它们使用一系列可能在蓝藻门的远缘世系中独立发展的分子机制。这些过程共同感测并响应了大多数与光合相关的太阳光谱，这表明CA在广泛的浅色生态位中提供了健身优势。对几种新型CA类型的最新发现表明，在未来几年中将揭示涉及其他浅色和分子机制的其他CA系统。
