斯坦福大学研究人员发现，濒危的白化珊瑚仅需与遗传同源的健康珊瑚接触数天，就能在七周内完全恢复1。研究显示，白化珊瑚只需与健康珊瑚接触5天至1周，就足以启动恢复过程1。接触后第三天内，研究人员观察到有益藻类开始转移到受损的珊瑚碎片中，随后藻类在新宿主体内迅速繁殖，第二周内每4天增长一倍，增速约为野生珊瑚的十倍1。
这一发现源于一次实验室事故，为珊瑚礁修复提供了全新的可能性2。研究团队首席作者Danny Collins指出，"白化珊瑚可能在死亡，但还没有死"1。斯坦福大学研究员Steve Palumbi解释了其中的生物学机制，称"遗传同源的珊瑚相互识别时，它们的组织会融合。我们在人类中看到类似的现象——器官移植通常在捐献者是你的同卵双胞胎时成功"1。该研究已于2026年10月14日发表在《科学进展》杂志上，获得了美国国家科学基金会和斯坦福大学的资助支持1。研究团队表示，未来将探索在不需物理接触的情况下传递有益藻类的方法1。
Stanford University researchers have discovered that bleached corals can fully recover within seven weeks when placed in contact with healthy, genetically compatible corals.1 The recovery process begins remarkably quickly: beneficial algae start transferring to damaged coral fragments within three days of contact, and the corals need only five days to one week of direct contact to initiate the restoration.1 During the second week, the beneficial algae in the recovering corals double every four days—approximately ten times faster than in wild corals.1
The mechanism behind this recovery relies on tissue fusion between genetically compatible corals.1 Lead researcher Danny Collins explained that "bleached corals may be dying, but they are not yet dead."1 Steve Palumbi, another member of the research team, drew a parallel to human organ transplantation: "When genetically compatible corals recognize each other, their tissues fuse. We see similar phenomena in humans—organ transplants typically succeed when the donor is your identical twin."1
The research was led by Stanford University's Doerr School of Sustainability and funded by the National Science Foundation and Stanford University, with findings published in Science Advances on October 14, 2026.1 This discovery emerged from a laboratory accident and offers a promising new approach to reversing coral bleaching and restoring endangered reef ecosystems.12 Future investigations will explore methods of transferring beneficial algae without requiring physical contact between corals.1
