Root exudation is a key process for plant nutrient acquisition, but the controls on root exudation and its relationship to soil C and N processes in agroecosystems are unclear. We hypothesized that ro
Untargeted polar metabolomics of B. distachyon root exudates under varying iN supply. B. distachyon plants were grown for 3 weeks on 5 mM inorganic nitrogen (iN) as NO3-, NH4+, or NH4NO3 and then tran
