lacks canonical siderophore pathways but employs a noncanonical iron-acquisition strategy, which may contribute to enhanced iron availability under trace metal-limited conditions. These results provide experimental evidence that specific bacterial lineages closely associated with toxic dinoflagellates can promote their proliferation. Our findings highlight the ecological significance of dinoflagellate-associated core microbiota and offer new directions for microbiome-informed strategies in HAB monitoring and management.
