Dimethylsulfoniopropionate (DMSP) and dimethylsulfide (DMS) are key compounds in the global sulfur cycle. Moreover, DMS is particularly important in climate regulation owing to its role in cloud formation. Reef building corals are major contributors to the production of these two compounds and also form diverse and complex associations with bacteria, which are known to play a crucial role in the degradation of DMSP and DMS. Here, we highlight an extensive overlap between bacterial species implicated in DMSP/DMS degradation and those associated with corals, leading to the hypothesis that these two compounds play a major role in structuring coral-associated bacterial communities, with important consequences for coral health and the resilience of coral reefs. We also explore the publically available metagenome databases and show that genes implicated in DMSP metabolism are abundant in the viral component of coral-reef-derived metagenomes, indicating that viruses can act as a reservoir for such genes.
二甲基巯基丙酸酯（DMSP）和二甲硫（DMS）是全球硫循环中的关键化合物。此外，由于其在云形成中的作用，DMS 在气候调节中尤为重要。造礁珊瑚是这两种化合物的主要生产者，并且与细菌形成多样而复杂的联系，这些细菌被认为在 DMSP 和 DMS 的降解中起着至关重要的作用。在这里，我们强调了参与 DMSP/DMS 降解的细菌物种与与珊瑚相关的细菌物种之间的广泛重叠，从而提出了这样一个假设，即这两种化合物在构建珊瑚相关细菌群落中起着重要作用，这对珊瑚健康和珊瑚礁的恢复力有重要影响。我们还探索了公开的宏基因组数据库，并表明与 DMSP 代谢相关的基因在珊瑚礁衍生宏基因组的病毒成分中丰富，表明病毒可以作为此类基因的储库。
