QuerySeed germination is a vital step in the life cycle of a plant, playing a significant role in seedling establishment and crop yield potential. It is also an important factor in the conservation of plant germplasm resources. This complex process is influenced by a myriad of factors, including environmental conditions, the genetic makeup of the seed, and endogenous hormones. The perception of these environmental signals triggers a cascade of intricate signal transduction events that determine whether a seed germinates or remains dormant. Despite considerable progress in uncovering the molecular mechanisms governing these processes, many questions remain unanswered. In this review, we summarize the current progress in the molecular mechanisms underlying the perception of environmental signals and consequent signal transduction during seed germination, and discuss questions that need to be addressed to better understand the process of seed germination and develop novel strategies for germplasm improvement.
种子萌发是植物生命周期中的关键步骤,对幼苗建立和作物产量潜力起着重要作用。它也是植物种质资源保护的重要因素。这个复杂的过程受到众多因素的影响,包括环境条件、种子的基因组成和内源激素。对这些环境信号的感知引发了一系列复杂的信号转导事件,这些事件决定了种子是发芽还是保持休眠。尽管在揭示调控这些过程的分子机制方面取得了相当大的进展,但许多问题仍未得到解答。在本综述中,我们总结了种子萌发过程中环境信号感知及后续信号转导的分子机制的当前进展,并讨论了为更好地理解种子萌发过程和开发种质改良新策略而需要解决的问题。
