1126-珊瑚御敌:高效反硝化细菌缓解硝酸盐压力之谜

from 聊聊Sci

这篇文章探讨了香港珊瑚礁如何在严重营养盐污染(尤其是高硝酸盐)的环境中生存。研究发现,这种抗性并非源于微生物属级层面的多样性变化,而是与Ruegeria属中特定的高效脱氮功能群体(denitrifying specialists)密切相关。这些“专家型”细菌种群在富营养化水域的珊瑚中显著富集,其将有害硝酸盐转化为惰性氮气的效率比普通种群高出10倍。通过整合种群基因组学、高分辨率元条形码技术和同位素追踪实验,研究人员证明了这些微小的微生物盟友是珊瑚适应人为环境压力的关键。这项工作揭示了亚属水平的微生物演化对宿主健康的重大意义,并为理解边缘珊瑚绿洲的维持机制提供了新框架。References:Xiang N, Liao T, Xie M, Wang Z, Mak CH, Tang X, McIlroy SE, Thibodeau B, Voolstra CR, Luo H.
