Abstract

In angiosperms, double fertilization triggers the concomitant development of two closely juxtaposed tissues, the embryo and the endosperm. Successful seed development and germination require constant interactions between these tissues, which occur across their common interface. The embryo-endosperm interface is a complex and poorly understood compound apoplast comprising components derived from both tissues, across which nutrients transit to fuel embryo development. Interface properties, which affect molecular diffusion and thus communication, are themselves dynamically regulated by molecular and physical dialogues between the embryo and endosperm. We review the current understanding of embryo-endosperm interactions, with a focus on the structure, properties, and function of their shared interface. Concentrating on Arabidopsis, but with reference to other species, we aim to situate recent findings within the broader context of seed physiology, developmental biology, and genetic factors such as parental conflicts over resource allocation.

Embryo-Endosperm交互。
在被子植物中,双受精触发两个紧密并列的组织——胚胎和胚乳的同时发育。成功的种子发育和萌发需要这些组织之间不断的相互作用,这些相互作用发生在它们的共同界面上。胚胎-胚乳界面是一种复杂且鲜为人知的复合外质体,包括来自两个组织的成分,营养物质通过该外质体转运以促进胚胎发育。界面特性影响分子的扩散和交流,其本身是由胚胎和胚乳之间的分子和物理对话动态调节的。我们回顾了目前对胚胎-胚乳相互作用的理解,重点介绍了它们共享界面的结构、性质和功能。本研究主要集中在拟南芥上,但也涉及到其他物种,我们的目标是将最近的研究结果置于种子生理学、发育生物学和遗传因素(如亲代资源分配冲突)的更广泛背景下。
