Decades of research have primarily emphasized genetic blueprint as the driving force behind plant regeneration. The flow of information from genetics, which manifests as biochemical properties, including hormones, has been extensively implicated in plant regeneration. However, recent advancements have unveiled additional intrinsic modules within this information flow. Here, we explore the three core modules of plant regeneration: biochemical properties, mechanical forces acting on cells, and cell geometry. We debate their roles and interactions during morphogenesis, emphasizing the potential for multiple feedbacks between these core modules to drive pattern formation during regeneration. We propose that de novo organ regeneration is a self-organized event driven by multidirectional information flow between these core modules.
几十年来的研究主要强调遗传蓝图是植物再生的驱动力。信息从遗传学的流动,表现为包括激素在内的生化特性,广泛涉及植物再生。然而,最近的进展揭示了这个信息流中的其他内在模块。在这里,我们探讨了植物再生的三个核心模块:生化特性、作用于细胞的机械力和细胞几何形状。我们讨论了它们在形态发生过程中的作用和相互作用,强调了这些核心模块之间的多个反馈可能有助于再生过程中的模式形成。我们提出,新器官的再生是由这些核心模块之间的多向信息流驱动的自组织事件。
