蓝藻是研究光合作用、氮代谢、毒素合成和盐适应的模式生物。然而，与其他模式细菌相比，对调控网络知之甚少，该网络允许蓝藻适应不断变化的环境条件。目前的工作已经开始阐明转录因子如何调节不同光合调节子的表达。在过去的几年中，对其他调控原理如RNA调控的研究表明，非蛋白质调节剂对细菌生活方式的重要性。光合组件调制的调查应阐明的贡献范围内的一个更大的监管network.Here，我们专注于调节光合过程，包括转录和转录后机制，引用的例子从数量有限的蓝藻物种的所有因素。虽然，一般的想法适用于大多数物种，不同的生物之间存在重要的差异，说明在非常异质的蓝藻分支的驯化策略的多样性。本文是由Conrad Mullineaux教授编辑的题为细菌生物能量系统的组织和动力学的特刊的一部分。
Cyanobacteria are well established model organisms for the study of oxygenic photosynthesis, nitrogen metabolism, toxin biosynthesis, and salt acclimation. However, in comparison to other model bacteria little is known about regulatory networks, which allow cyanobacteria to acclimate to changing environmental conditions. The current work has begun to illuminate how transcription factors modulate expression of different photosynthetic regulons. During the past few years, the research on other regulatory principles like RNA-based regulation showed the importance of non-protein regulators for bacterial lifestyle. Investigations on modulation of photosynthetic components should elucidate the contributions of all factors within the context of a larger regulatory network.Here, we focus on regulation of photosynthetic processes including transcriptional and posttranscriptional mechanisms, citing examples from a limited number of cyanobacterial species. Though, the general idea holds true for most species, important differences exist between various organisms, illustrating diversity of acclimation strategies in the very heterogeneous cyanobacterial clade. This article is part of a Special Issue entitled Organization and dynamics of bioenergetic systems in bacteria, edited by Prof Conrad Mullineaux.
