摘要

在被子植物中，来自伤口的信号通过脉管系统激活整个植株的防御反应。在拟南芥中，脉管特异性 3 族谷氨酸受体样（GLR）通道的活性是电信号和细胞膜 Ca2+ （[Ca2+]cyt）波从受伤叶片传输到远端组织所必需的，从而触发了依赖氧脂素的防御激活。非维管束植物在受伤时是否会产生系统反应仍是未知数。为了探索系统防御反应的演变，我们研究了非维管束植物 Marchantia polymorpha 的电信号和钙信号。我们发现，电信号和[Ca2+]cyt 波是对机械伤口的反应，并传播到多甲马钱科植物未受损的远端组织。MpGLR 是 M. polymorpha 基因组中唯一编码的 GLR，对它的功能分析表明，它的活性对于伤口诱导的电信号和[Ca2+]cyt 波的系统传播是必要的，这一点与维管植物类似。然而，这些信号的传播既没有与氧化脂素的系统积累相联系，也没有与受伤的多甲藻植物远端组织的转录防御反应相联系。我们的研究结果表明，缺乏脉管系统阻碍了其他信号因子的转移，而这些信号因子与电信号和[Ca2+]cyt 波一起，有助于激活气管植物的系统防御能力。

期刊介绍： New Phytologist is an international electronic journal published 24 times a year. It is owned by the New Phytologist Foundation, a non-profit-making charitable organization dedicated to promoting plant science. The journal publishes excellent, novel, rigorous, and timely research and scholarship in plant science and its applications. The articles cover topics in five sections: Physiology & Development, Environment, Interaction, Evolution, and Transformative Plant Biotechnology. These sections encompass intracellular processes, global environmental change, and encourage cross-disciplinary approaches. The journal recognizes the use of techniques from molecular and cell biology, functional genomics, modeling, and system-based approaches in plant science. Abstracting and Indexing Information for New Phytologist includes Academic Search, AgBiotech News & Information, Agroforestry Abstracts, Biochemistry & Biophysics Citation Index, Botanical Pesticides, CAB Abstracts®, Environment Index, Global Health, and Plant Breeding Abstracts, and others.
