The ability of a seed to germinate and establish a plant at the right time of year is of vital importance from an ecological and economical point of view. Due to the fragility of these early growth stages, their swiftness and robustness will impact later developmental stages and crop yield. These traits are modulated by a continuous interaction between the genetic makeup of the plant and the environment from seed production to germination stages. In this review, we have summarized the established knowledge on the control of seed germination from a molecular and a genetic perspective. This serves as a “backbone” to integrate the latest developments in the field. These include the link of germination to events occurring in the mother plant influenced by the environment, the impact of changes in the chromatin landscape, the discovery of new players and new insights related to well-known master regulators. Finally, results from recent studies on hormone transport, signaling, and biophysical and mechanical tissue properties are underscoring the relevance of tissue-specific regulation and the interplay of signals in this crucial developmental process.

种子发芽规定的更新概述。

从生态和经济的角度来看,种子在一年中的正确时间发芽和植株的能力至关重要。由于这些早期生长阶段的脆弱性,它们的迅速性和健壮性将影响后期的发育阶段和作物产量。从植物的基因组成和环境(从种子生产到发芽阶段)之间的持续相互作用,可以调节这些性状。在这篇综述中,我们从分子和遗传的角度总结了关于控制种子发芽的已知知识。这是整合该领域最新发展的“骨干”。这些因素包括发芽与受环境影响的母本植物中发生的事件,染色质景观变化的影响,发现与知名监管机构有关的新参与者和新见解。最后,最近有关激素转运,信号传导以及生物物理和机械组织特性的研究结果强调了组织特异性调节的相关性以及信号在这一至关重要的发育过程中的相互作用。
