The Gordon and Betty Moore Foundation’s Symbiosis in Aquatic Systems Initiative is investing $19 million over the next three years to support 42 teams of scientists, including three teams with �������� researchers, to collaboratively develop tools and methods to advance model systems in aquatic symbiosis. The Initiative’s funding aims to equip the scientific community with infrastructure such as new genetic tools, cultivation methods, and nanoscale microscopy to improve experimental capabilities in aquatic symbiosis research over the coming decade.��

The �������� scientists funded in this grant include:

Project title:��Underground Allies: Dynamic Interactions Among Cordgrass (Spartina alterniflora) and Sulfur-Cycling Microbes in the Rhizosphere
Principal Investigator:��Zoe Cardon, ��������
Co-Investigators:��Anne Giblin, Elena L. Peredo, Blair Paul, and Emil Ruff, ��������

���ܳ���������:��Spartina alterniflora����is a native cordgrass dominating intertidal salt marsh platforms along thousands of miles of the U.S. East and Gulf coasts. The interaction among��Spartina��roots, sulfate reducing bacteria, and sulfur oxidizing bacteria is at the core of salt marsh health. We aim to establish a model system for understanding mechanisms underlying this symbiosis using plants and microbes isolated from the Plum Island Ecosystem Long Term Ecological Research site north of Boston. The��Spartina��root system and its associated sulfur-cycling microbes control an ecosystem-scale production, recycling and detoxification system, maintaining vast expanses of clonal��Spartina��that are��crucibles for marine coastal life, and creating��peat platforms critical for salt marsh persistence in the face of rising sea levels.
