Plants grow and reproduce within a highly dynamic environment that can see abrupt changes in conditions, such as light intensity, temperature, humidity, or interactions with biotic agents. Recent studies revealed that plants can respond within seconds to some of these conditions, engaging many different metabolic and molecular networks, as well as rapidly altering their stomatal aperture. Some of these rapid responses were further shown to propagate throughout the entire plant via waves of reactive oxygen species (ROS) and Ca that are possibly mediated through the plant vascular system. Here, we propose that the integration of these signals is mediated through pulses of gene expression that are coordinated throughout the plant in a systemic manner by the ROS/Ca waves.
植物在高度动态的环境中生长和繁殖，该环境中的条件会突然发生变化，例如光照强度、温度、湿度或与生物因素的相互作用。最近的研究表明，植物可以在几秒钟内对其中一些条件做出反应，激活许多不同的代谢和分子网络，并迅速改变其气孔开度。这些快速反应中的一些进一步被证明可以通过活性氧（ROS）和钙的波在整个植物中传播，这些波可能是通过植物的维管束系统介导的。在这里，我们提出这些信号的整合是通过 ROS/Ca 波在系统上协调植物中基因表达的脉冲来介导的。
