报告摘要:

Coral reefs possess the highest biodiversity in the tropical oceans. Corals harbor a highly diverse microbial community in their tissue, skeleton and mucus layer. Competitive interactions between opportunistic coral pathogens and other commensal microbes affect coral health. We recently found that temperate phages played a major role in mediating colonization competition in the coral microbiota. Pathogen-encoded LodAB, which produces hydrogen peroxide, triggers the lytic cycle of prophage in coral symbiotic bacteria through LodAB-dependent prophage induction. We reveal that LodAB can be used by pathogens as an important weapon to gain a competitive advantage over lysogenic competitors when colonizing corals. The interplay of LodAB and inducible prophages may act as an important intrinsic force modulating changes in the microbiota in response to environmental fluctuations.
