蓝藻是一门细菌,其成员具有高度的超微结构组织和独特的基因调控机制。解开这种复杂性需要使用活细胞荧光显微镜,但受到与光收集色素相关的固有荧光背景和需要为光合细胞提供光的阻碍。在这里,我们概述了克服这些挑战的路线图。具体来说,我们表明,尽管基本的蓝藻生物学创造了具有挑战性的实验限制,这些限制可以通过仔细选择荧光团和显微镜仪器来减轻。这些选择中的许多都是受到最近成功的活细胞研究的启发。因此,我们也强调活细胞成像如何提高了我们对细菌微室、昼夜节律以及细菌类核的组织和分离的理解。
Cyanobacteria are a diverse bacterial phylum whose members possess a high degree of ultrastructural organization and unique gene regulatory mechanisms. Unraveling this complexity will require the use of live-cell fluorescence microscopy, but is impeded by the inherent fluorescent background associated with light-harvesting pigments and the need to feed photosynthetic cells light. Here, we outline a roadmap for overcoming these challenges. Specifically, we show that although basic cyanobacterial biology creates challenging experimental constraints, these restrictions can be mitigated by the careful choice of fluorophores and microscope instrumentation. Many of these choices are motivated by recent successful live-cell studies. We therefore also highlight how live-cell imaging has advanced our understanding of bacterial microcompartments, circadian rhythm, and the organization and segregation of the bacterial nucleoid.
