Seed maturation depends on well-coordinated communications between the processes of endosperm and embryo development. The endosperm is considered to be destined to support embryo development and the timing of endosperm cellularization is critical for embryo growth. Recent findings suggest that the endosperm development and the onset of embryo maturation are two independent processes during seed development. Meanwhile, it is lately reported that several mobile regulators originating from the endosperm are needed to ensure proper embryo growth and seed maturation. In this opinion article, we highlight processes on how endosperm communicates with embryo during seed development and discuss some intriguing questions in light of the latest advancements.
种子成熟取决于胚乳和胚胎发育过程之间协调良好的通讯。胚乳被认为是注定要支持胚胎发育的，而胚乳细胞化的时间对胚胎生长至关重要。最近的研究结果表明，在种子发育过程中，胚乳发育和胚胎成熟的开始是两个独立的过程。同时，最近有报道称，需要几种来自胚乳的移动调节因子来确保胚胎的正常生长和种子的成熟。在这篇观点文章中，我们重点介绍了种子发育过程中胚乳与胚胎如何通讯的过程，并根据最新进展讨论了一些有趣的问题。
