PARSEC: Plant and Rhizobacteria Symbioses to Enhance Crops
Plant Growth Promoting Rhizobacteria (PGPR) are being investigated to determine how to best exploit them to benefit plant production. While they have many potential applications on Earth, researchers at NASA are working to determine if PGPR could be used to improve plant growth in the context of space exploration. Six different bacterial isolates from plant material on the International Space Station were used to inoculate Brachypodium distachyon seeds which were then grown and observed. There were no definitively positive growth promoting effects, however this work paves the way for future trials with different variables. If successful relationships between PGPR and food crops can be determined, it would make plant growth for food production much more feasible in beyond Earth environments.
