Invasive Spartina grasses accumulate high levels of intracellular dimethylsulfoniopropionate (DMSP). Here, the authors report the isolation and characterization of the genes involved in DMSP biosynthesis and show that administration of DMSP by root uptake or overexpression of the DMSP biosynthesis genes results in salinity and drought tolerance in Arabidopsis.
