研究植物器官的发育遗传学需要跟踪特定组织中的基因表达。为了促进这一点,我们开发了双表达解剖系,其中将红色质膜标记与同一载体中感兴趣的基因的荧光报告基因结合在一起。在这里,我们调整了 GreenGate 克隆载体来创建两个目标载体,在整个根或特别是侧根中显示出强烈的细胞膜标记。该系统也可用于胚胎和整苗。作为概念证明,我们在超过 24 小时的时间内跟踪了拟南芥 (Arabidopsis thaliana) 在侧根器官发生过程中的基因表达和解剖学。结合流动池和灌注系统的开发,我们跟踪了应用生长素后 DII 生长素传感器活性的变化。载体系统和流动池设置允许对拟南芥主根和侧根的基因表达和解剖结构进行长期成像。
Studying the developmental genetics of plant organs requires following gene expression in specific tissues. To facilitate this, we have developed dual expression anatomy lines, which incorporate a red plasma membrane marker alongside a fluorescent reporter for a gene of interest in the same vector. Here, we adapted the GreenGate cloning vectors to create two destination vectors showing strong marking of cell membranes in either the whole root or specifically in the lateral roots. This system can also be used in both embryos and whole seedlings. As proof of concept, we follow both gene expression and anatomy in Arabidopsis (Arabidopsis thaliana) during lateral root organogenesis for a period of over 24 h. Coupled with the development of a flow cell and perfusion system, we follow changes in activity of the DII auxin sensor following application of auxin. A vector system and flow cell set-up allow long-term imaging of both gene expression and anatomy in Arabidopsis primary and lateral roots.
