The ocean is home to a diverse and metabolically versatile microbial community that
performs the complex biochemical transformations that drive the nitrogen cycle, including …

Seagrasses are remarkable plants that have adapted to live in a marine environment. They
form extensive meadows found globally that bioengineer their local environments and …

Climate change is a defining challenge of the 21st century, and this decade is a critical time
for action to mitigate the worst effects on human populations and ecosystems. Plant science …

Human civilization relies on estuaries, and many estuarine ecosystem services are provided
by microbial communities. These services include high rates of primary production that …

Nitrogen (N) and phosphorus (P) are the most important macronutrients required for plant
growth and development. To cope with the limited and uneven distribution of N and P in …

We present chromosome-level genome assemblies from representative species of three
independently evolved seagrass lineages: Posidonia oceanica, Cymodocea nodosa …

Biological dinitrogen (N2) fixation supplies nitrogen to the oceans, supporting primary
productivity, and is carried out by some bacteria and archaea referred to as diazotrophs …

Background Plants sustain intimate relationships with diverse microbes. It is well-recognized
that these plant-associated microbiota shape individual performance and fitness of host …

The high diversity and global distribution of heterotrophic bacterial diazotrophs (HBDs) in
the ocean has recently become apparent. However, understanding the role these largely …

Biological nitrogen (N 2) fixation is critical in global biogeochemical cycles and in sustaining
the productivity of the oceans. There remain many unanswered questions, unresolved …
