Polarity is an essential feature of multicellular organisms and underpins growth and development as well as physiological functions. In polyhedral plant cells, polar domains at different faces have been studied in detail. In recent years, cell edges (where two faces meet) have emerged as discrete spatial domains with distinct biochemical identities. Here, we review and discuss recent advances in our understanding of cell edges as functional polar domains in plant cells and other organisms, highlighting conceptual parallels and open questions regarding edge polarity.

前卫的重要性：细胞几何边缘作为植物细胞中新兴的极性域


极性是多细胞生物的基本特征，是生长发育以及生理功能的基础。在多面体植物细胞中，不同面的极性域已被详细研究。近年来，细胞边缘（两个面相遇的地方）已成为具有不同生化特性的离散空间域。在这里，我们回顾并讨论了我们对细胞边缘作为植物细胞和其他生物体中功能极性域的理解的最新进展，强调了概念上的相似之处和有关边缘极性的开放性问题。
