Nitric Oxide Negatively Regulates Larval Metamorphosis in Hard-Shelled Mussel (Mytilus coruscus)

Marine invertebrates undergo distinct life cycles and development processes, and some undergo a metamorphic transition from pelagic larvae to benthic juvenile. Previous studies have shown that the second messenger nitric oxide (NO) plays important roles in regulating larval metamorphosis in marine invertebrates. However, this regulatory function is not conserved. Herein, we investigated the regulatory role of NO in larval metamorphosis in...
