We detected N-fixing bacteria in surface-sterilized seagrass roots.

The diversity of diazotrophs based on nitrogenase gene (nifH) sequences is low.

Species-specific relationships between bacteria and seagrasses are suggested.

Symbiotic interactions could play a major role in N acquisition by seagrasses.
