在多细胞生物体中,不同类型的组织具有与细胞的特定功能或结构相关的不同基因表达谱。整个器官或整个生物体中基因表达的量化可能会提供有关特定细胞类型的表达水平或动态的误导性信息。基因表达的组织或细胞特异性分析有可能增强我们对基因调控和细胞信号网络相互作用的理解。拟南芥昼夜节律振荡器是一个基因网络,它在昼夜周期中协调有节奏的表达。振荡器的组成和行为的细胞和组织类型之间存在异质性。为了更好地理解基因表达的空间和时间模式,需要灵活的工具。通过将 Gateway® 兼容的分裂荧光素酶构建体与 aGAL4 GFPenhancer trap 系统相结合,我们描述了一种组织特异性分裂荧光素酶测定,用于非侵入性检测拟南芥中的时空基因表达。我们展示了这种增强子陷阱兼容的分裂荧光素酶测定(ETSLA)系统在研究昼夜节律基因表达的组织特异性动态方面的实用性。我们确认了拟南芥叶子中昼夜节律基因表达的空间异质性,并描述了可用于研究任何感兴趣基因的资源。
In multicellular organisms different types of tissues have distinct gene expression profiles associated with specific function or structure of the cell. Quantification of gene expression in whole organs or whole organisms can give misleading information about levels or dynamics of expression in specific cell types. Tissue‐ or cell‐specific analysis of gene expression has potential to enhance our understanding of gene regulation and interactions of cell signalling networks. The Arabidopsis circadian oscillator is a gene network which orchestrates rhythmic expression across the day/night cycle. There is heterogeneity between cell and tissue types of the composition and behaviour of the oscillator. In order to better understand the spatial and temporal patterns of gene expression, flexible tools are required. By combining a Gateway®‐compatible split luciferase construct with aGAL4 GFPenhancer trap system, we describe a tissue‐specific split luciferase assay for non‐invasive detection of spatiotemporal gene expression in Arabidopsis. We demonstrate the utility of this enhancer trap‐compatible split luciferase assay (ETSLA) system to investigate tissue‐specific dynamics of circadian gene expression. We confirm spatial heterogeneity of circadian gene expression in Arabidopsis leaves and describe the resources available to investigate any gene of interest.
