Effects of Nodulation on Metabolite Concentrations in Xylem Sap and in the Organs of Soybean Plants Supplied with Different N Forms [PDF]
Metabolites, 2023 The effects of nodulation on N metabolism in soybean plants supplied with various forms of N are not fully understood. Ureides are the principal forms of N transported from nodules, but nitrate and asparagine are the primary N compounds transported from ...

Nitrogen Metabolism in Non-Nodulated and Nodulated Soybean Plants Related to Ureide Synthesis
Nitrogen, 2023 Soybean plants can fix atmospheric N2 in the root nodule, a symbiotic organ with rhizobia. The primary forms of N transported from N2 fixation are ureides, allantoate, and allantoin, supplemented with asparagine.
