温度对种子的休眠和萌发有关键影响，使野生植物的生活史与季节同步。在这篇综述中，我们讨论了通过温度整合到种子生理和控制初级和次级休眠的信号通路，重点是了解母系的影响和合子组织的反应。一个关键的新兴范式是，种子中的温度信号必须与整个植物的遗传学和生理学联系起来理解，因为温度传感和激素信号通路的重叠多效性作用是司空见惯的。
Abstract Temperature has a key influence over seed dormancy and germination, allowing wild plants to synchronize their life history with the seasons. In this review we discuss the signalling pathways through which temperature is integrated into seed physiology and the control of primary and secondary dormancy, with an emphasis on understanding maternal effects and responses dictated by the zygotic tissues. A key emerging paradigm is that temperature signalling in seeds must be understood in relation to whole plant genetics and physiology, as overlapping pleiotropic roles for temperature sensing and hormone signalling pathways are commonplace.
