Phytohormones enable plants to regulate their development, growth and physiology according to the environmental requirements. Knowledge about the underlying signaling mechanisms, combined with the ability to pharmacologically or genetically manipulate phytohormone responses is steadily being incorporated into modern plant biology research and agriculture. This knowledge also enabled the development of genetically encoded phytohormone indicators that allow the tracking of spatiotemporal phytohormone dynamics and signaling processes in vivo. This review aims to provide an overview about core phytohormone signaling mechanisms, and about genetic tools for the manipulation and in vivo tracking of phytohormone actions.

植物激素使植物能够根据环境要求调节其发育，生长和生理。关于潜在信号机制的知识，结合药理或遗传操纵植物激素反应的能力，正在稳步纳入现代植物生物学研究和农业中。这项知识还促进了遗传编码植物激素指标的发展，这些指标可以追踪体内时空植物激素的动态和信号传导过程。这篇综述旨在提供有关核心植物激素信号传导机制的概述，以及有关操纵和体内追踪植物激素作用的遗传工具的概述。
