中新网上海5月16日电 （记者 郑莹莹）北京时间5月15日深夜，中国科研团队在国际知名学术期刊《自然》上发表了一项关于水稻免疫机制的新成果，揭示了植物如何巧妙地使用免疫系统这把“双刃剑”。
这项研究主要围绕一种名为“紧箍圈”的调控蛋白展开。在水稻中，这种蛋白像紧箍咒一样，对免疫系统的活动进行精细调控，既能让植物有效地抵御病原体，又能避免过度免疫带来的损伤。
研究结果显示，当水稻遭受病原体侵袭时，“紧箍圈”蛋白会被激活，它一方面能够促进免疫反应，帮助植物抵御病原体；另一方面，又能适时抑制免疫反应，防止植物因免疫过度而损伤自身。
这一发现有助于人们深入理解植物免疫系统的复杂性，对提高水稻等农作物的抗病性和产量具有重要意义。科研人员表示，未来可以通过基因编辑等技术手段，对“紧箍圈”蛋白进行改良，培育出更抗病、更高产的农作物。
此外，这一研究也为植物免疫学领域提供了新的研究思路，或将对其他植物乃至动物免疫机制的研究产生积极影响。

#### Researchers Unveil How Plants Cleverly Utilize Immune System: Discovery of “Magic Ring” Regulatory Protein
SHANGHAI, May 16 (Xinhua) — (Reporter Zheng Yiding) In the early morning of May 15, a research team from China published a new finding on the immune mechanism of rice in the internationally renowned academic journal *Nature*. The study reveals how plants ingeniously use their immune system, a “double-edged sword”.
The research primarily focuses on a regulatory protein named “magic ring”. In rice, this protein functions like the magic headband from the classic tale, finely tuning the activities of the immune system. It allows plants to effectively resist pathogens while avoiding damage caused by an overactive immune response.
The results show that when rice is attacked by pathogens, the “magic ring” protein is activated. On one hand, it promotes the immune response, helping the plant to fight off pathogens; on the other hand, it timely inhibits the immune response to prevent the plant from self-damage due to excessive immunity.
This discovery contributes to a deeper understanding of the complexity of the plant immune system and is of great significance for improving the disease resistance and yield of crops such as rice. Researchers indicate that in the future, it may be possible to breed more disease-resistant and high-yield crops by modifying the “magic ring” protein through techniques such as genetic editing.
Furthermore, this study provides new insights into the field of plant immunology and could have a positive impact on the research of immune mechanisms in other plants and even animals.
