As scientists, we are at least as excited about the open questions—the things we do not know—as the discoveries. Here, we asked 15 experts to describe the most compelling open questions in plant cell biology. These are their questions: How are organelle identity, domains, and boundaries maintained under the continuous flux of vesicle trafficking and membrane remodeling? Is the plant cortical microtubule cytoskeleton a mechanosensory apparatus? How are the cellular pathways of cell wall synthesis, assembly, modification, and integrity sensing linked in plants? Why do plasmodesmata open and close? Is there retrograde signaling from vacuoles to the nucleus? How do root cells accommodate fungal endosymbionts? What is the role of cell edges in plant morphogenesis? How is the cell division site determined? What are the emergent effects of polyploidy on the biology of the cell, and how are any such “rules” conditioned by cell type? Can mechanical forces trigger new cell fates in plants? How does a single differentiated somatic cell reprogram and gain pluripotency? How does polarity develop de-novo in isolated plant cells? What is the spectrum of cellular functions for membraneless organelles and intrinsically disordered proteins? How do plants deal with internal noise? How does order emerge in cells and propagate to organs and organisms from complex dynamical processes? We hope you find the discussions of these questions thought provoking and inspiring.

植物细胞生物学中十五个引人注目的开放性问题

作为科学家,我们至少对开放性问题(我们不知道的事情)和发现一样兴奋。在这里,我们请了 15 位专家来描述植物细胞生物学中最引人注目的开放性问题。这些是他们的问题:在囊泡运输和膜重塑的持续流动下,细胞器身份、结构域和边界是如何维持的?植物皮层微管细胞骨架是一种机械感觉装置吗?细胞壁合成、组装、修饰的细胞通路如何,和植物中的完整性传感?为什么胞间连丝会打开和关闭?是否存在从液泡到细胞核的逆行信号?根细胞如何容纳真菌内共生体?细胞边缘在植物形态发生中的作用是什么?细胞分裂位点是如何确定的?多倍体对细胞生物学的紧急影响是什么,这些“规则”是如何以细胞类型为条件的?机械力能否触发植物新的细胞命运?单个分化的体细胞如何重编程并获得多能性?极性如何在分离的植物细胞中从头发展?无膜细胞器和本质上无序的蛋白质的细胞功能范围是什么?植物如何处理内部噪音?秩序如何在细胞中出现并从复杂的动力学过程传播到器官和生物体?我们希望您发现对这些问题的讨论发人深省和鼓舞人心。
