As sessile organisms, terrestrial plants have evolved sophisticated mechanisms to coordinate the growth and development of two distinct systems, the shoot and the root, in response to environmental fluctuations. Adaptive systemic responses are accomplished by shoot-root communication, which involves diverse long-distance signalling molecules. During the last few decades, various genetic, biochemical, molecular, and grafting studies have identified multiple long-distance signalling molecules which are crucial for plants to adapt to external changes. In this minireview, the long-distance signals implicated in systemic responses to various environmental cues are discussed.
作为固着生物，陆生植物已经进化出了复杂的机制来协调两个不同系统（地上部分和地下部分）的生长和发育，以应对环境波动。适应系统反应是通过地上部分-地下部分通讯来完成的，其中涉及多种长距离信号分子。在过去的几十年中，各种遗传、生化、分子和嫁接研究已经确定了多种长距离信号分子，这些信号分子对于植物适应外部变化至关重要。在这篇综述中，讨论了参与植物对各种环境信号的系统反应的长距离信号。
