细菌生物发光被广泛用于研究细菌种群的时空动态和基因在体内的表达,但不易用于研究单个细胞水平上的细菌活性。在这项研究中,我们描述了一个新的迷你- Tn7 - lux和lux::eyfp报告结构文库的开发,提供了广泛的lux表达水平,并结合了细菌生物发光和荧光蛋白的优势,以弥合宏观和微观成像技术之间的差距。我们证明了利用lux操纵子和eYFP的双重生物发光-荧光方法可以在宏观和微观上监测植物中的细菌运动,并证明了丁香假单胞菌pv phaseolicola可以定殖在叶片维管系统中并系统感染普通豆(Phaseolus vulgaris)的叶片。我们还表明,细菌生物发光可用于研究植物免疫应答对植物组织内细菌繁殖、活力和传播的影响。本研究中描述的结构和方法可用于研究细菌定植的时空动态,并在广泛的生物学背景下将种群动态和细胞相互作用联系起来。
Bacterial bioluminescence is widely used to study the spatiotemporal dynamics of bacterial populations and gene expression in vivo at a population level but cannot easily be used to study bacterial activity at the level of individual cells. In this study, we describe the development of a new library of mini‐Tn7‐lux and lux::eyfp reporter constructs that provide a wide range of lux expression levels, and which combine the advantages of both bacterial bioluminescence and fluorescent proteins to bridge the gap between macro‐ and micro‐scale imaging techniques. We demonstrate that a dual bioluminescence‐fluorescence approach using the lux operon and eYFP can be used to monitor bacterial movement in plants both macro‐ and microscopically and demonstrate that Pseudomonas syringae pv phaseolicola can colonize the leaf vascular system and systemically infect leaves of common bean (Phaseolus vulgaris). We also show that bacterial bioluminescence can be used to study the impact of plant immune responses on bacterial multiplication, viability and spread within plant tissues. The constructs and approach described in this study can be used to study the spatiotemporal dynamics of bacterial colonization and to link population dynamics and cellular interactions in a wide range of biological contexts.
