ABOVE: The paving-stone arrangement of seaweed cells (Ulva mutabilis)

Scientists have sequenced the complete genome of a type of green seaweed, called Ulva mutabilis, for the first time, according to a study published September 13 in Current Biology. Ulva’s genome will help researchers study coastal biogeochemical cycles to which sulfur-producing green seaweed is a major contributor, as well as marine ecosystems penetrated by rapid algal growth and the evolution of multicellularity in green plants.
