单细胞组学技术及其在植物保卫细胞研究中的应用

单细胞组学技术在动物研究中已经得到广泛应用,但在植物学领域尤其是保卫细胞研究中还处于起步阶段。由保卫细胞构成的气孔承担着植物生命过程中水分散发及气体交换大门的作用。将单细胞组学技术应用到保卫细胞功能解析中将有助于了解保卫细胞参与的基本生理过程。该文综述了植物单细胞组学技术的发展、保卫细胞研究现状及单细胞组学技术在植物保卫细胞研究中的初步应用,为借助该技术解决植物生物学中保卫细胞发育、代谢及对环境胁迫响应等基本问题提供研究思路和方法。

Applications of Single-cell Technologies in Guard Cells

Single-cell technologies have been used in an increasing number of animal studies, but the techniques have yet to be widely used in plants, especially in guard cells. Stomatal pores are formed by pairs of guard cells and serve as major gateways for both CO₂ influx into plants from the atmosphere and transpirational water loss. The application of single-cell technologies will be valuable for better understanding the underlying mechanisms of stomatal pores. In this review, we discuss single-cell technologies, current research and problems with guard cells and focus on the application of single-cell technologies to guard cells. Single-cell technologies may have potential to provide new perspectives for plant problems, such as development, metabolism and response to environmental stresses of guard cells.
