在多种生物体中观察到选择休眠还是继续生长，以响应特定的发育和环境信号。在高等植物中，这在种子休眠的建立和打破期间最为明显。随着分子遗传分析的出现，特别是在拟南芥中，涉及种子休眠建立和打破的基因已被鉴定。遗传分析表明，这些过程的调节需要一个激素衍生信息网络。在这篇综述中，我们重点关注激素，特别是激素之间的相互作用，用于调节种子休眠的建立和释放的例子。使用在控制特定发育程序方面重叠的多种激素，使种子能够根据特定的发育和环境线索灵活地做出决策。
The choice to become dormant versus continuing to grow is observed in a variety of organisms in response to specific developmental and environmental signals. In higher plants this is most obvious during both the establishment and breaking of seed dormancy. With the advent of molecular genetic analysis, particularly in Arabidopsis, genes involved in the establishment and breaking of seed dormancy have been identified. Genetic analysis suggests a web of hormone-derived information is required in the regulation of these processes. In this review we focus on examples of where hormones, and in particular cross-talk between hormones, is used to regulate both the establishment and release of seed dormancy. The use of multiple hormones that overlap in their control of specific developmental programs allows seeds to be flexible in making decisions in response to specific developmental and environmental cues.
