摘要/Abstract

摘要： 多细胞生物常因暴露在各种生物和非生物胁迫下而导致器官损伤或缺失。植物因固着性而演化出强大的再生能力以适应环境。尽管细胞损伤是植物组织修复和器官再生的原初物理诱因, 然而引发再生反应局部伤口信号的化学本质及其调控再生机制一直是科学界的难解之谜。最近一项研究发现1个调控植物局部伤口响应与再生能力的小肽REF1。研究表明, REF1与其受体PORK1通过植物损伤响应及细胞重编程关键转录因子WIND1促进植物再生。尤为重要的是, 外源施加REF1小肽可不同程度地提高几种作物的再生效率。这一发现不仅为理解植物损伤响应和再生的分子机制打开了全新视角, 而且为提高作物的再生能力和遗传转化效率提供了潜在的应用策略。

Abstract: Living organisms are often exposed to a wide range of biotic and abiotic stresses that cause severe wounding, leading to partial or complete organ loss. Being sessile, plants have evolved powerful regenerative capabilities to adapt to the environment. Wounding is a prerequisite for plant regeneration, the local wound signals that trigger regenerative responses remained unknown for centuries. A recent study has identified a small peptide, REF1, that regulates local wound responses and regeneration capabilities in plants. The study found that REF1 and its receptor PORK1 can promote plant regeneration by activating WIND1, a master regulator of wound-induced cellular reprogramming in plants. Crucially, exogenous application of the REF1 peptide can improve the regeneration efficiency of several crops to varying degrees. This discovery not only provides a new perspective on the molecular mechanisms of plant injury responses and regene- ration, but also offers potential application strategies for enhancing the regenerative capacity and transformation efficiency of crops.

图1 番茄REF1-PORK1-SIWIND1介导的损伤响应及再生正反馈环路 REF1 (绿色圆点)作为一个局部信号调节番茄组织修复和再生。损伤促进REF1产生, REF1通过与细胞表面受体PORK1结合, 启动SIWIND1调控的再生途径。除启动细胞重编程外, SIWIND1还可识别REF1前体基因PRP启动子上的VWRE基序, 以激活其表达, 从而放大REF1信号。

Figure 1 An REF1-PORK1-SIWIND1 directed positive feedback loop for wounding response and regeneration in tomato REF1 (green dots) is a local wounding signal that regulates tissue repair and regeneration in tomato. Injury triggers the production of REF1, which binds to PORK1 on the cell surface and subsequently initiates SlWIND1-regulated regeneration pathway. In addition to orchestrating the cellular reprogramming for regeneration, SlWIND1 can also bind the VWRE motif on the promoter of PRP to activate its expression, thereby amplifying the REF1 signaling for regeneration.
