Plant aerial epidermal tissues, like animal epithelia, act as load-bearing layers and hence play pivotal roles in development. The presence of tension in the epidermis has morphogenetic implications for organ shapes but it also constantly threatens the integrity of this tissue. Here, we explore the multi-scale relationship between tension and cell adhesion in the plant epidermis, and we examine how tensile stress perception may act as a regulatory input to preserve epidermal tissue integrity and thus normal morphogenesis. From this, we identify parallels between plant epidermal and animal epithelial tissues and highlight a list of unexplored questions for future research.
植物地上表皮组织与动物上皮组织一样，起着承重层的作用，因此在发育过程中发挥着关键作用。表皮中的张力对器官形状具有形态发生学意义，但也不断威胁着该组织的完整性。在这里，我们探讨了植物表皮中张力与细胞粘附之间的多尺度关系，并研究了拉伸应力感知如何作为一种调节输入来维持表皮组织的完整性，从而实现正常的形态发生。由此，我们确定了植物表皮组织与动物上皮组织之间的相似之处，并列出了一系列有待未来研究探索的问题。
