Determination of Ureides Content in Plant Tissues [PDF]
Bio-Protocol, 2020 The ureides allantoin and allantoate are the main organic nitrogen compounds transported in several legumes, predominantly from N2 fixation. Moreover, recent studies point out a remarkable role for allantoin during several stress responses of plants ...

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 ...

Enzymes and cellular interplay required for flux of fixed nitrogen to ureides in bean nodules [PDF]
Nature Communications, 2022 Tropical legumes export fixed nitrogen from nodules as ureides. Here, the authors describe how ureides are produced by several biosynthetic enzymes in different nodule cell types and provide explanations for metabolic compartmentation.

Exogenous Allantoin Confers Rapeseed (Brassica campestris) Tolerance to Simulated Drought by Improving Antioxidant Metabolism and Physiology [PDF]
Antioxidants, 2023 Allantoin is an emerging plant metabolite, but its role in conferring drought-induced oxidative stress is still elusive. Therefore, an experiment was devised to explore the role of allantoin (0.5 and 1.0 mM; foliar spray) in rapeseed (Brassica campestris

Nucleoside Metabolism Is Induced in Common Bean During Early Seedling Development [PDF]
Frontiers in Plant Science, 2021 Nucleoside hydrolases (NSH; nucleosidases) catalyze the cleavage of nucleosides into ribose and free nucleobases. These enzymes have been postulated as key elements controlling the ratio between nucleotide salvage and degradation.

Optimized nitrogen fertilizer management enhances soybean (Glycine max (L.) Merril.) yield and nitrogen use efficiency by promoting symbiotic nitrogen fixation capacity [PDF]
Frontiers in Plant ScienceIntroductionAlthough the mulched drip irrigation system combined with high nitrogen input (240∼310 kg ha-1) in Xinjiang, China, frequently achieves record-high soybean yields (6855 kg ha-1), this practice is not conducive to symbiotic nitrogen fixation ...
