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 ...

Effect of Nitrogen Source on Ureides in Soybean [PDF]
Plant Physiology, 1984 In field-grown soybeans (Glycine max L. Merr. cv Harosoy), the percentage of N in the xylem as ureides increased with increasing N(2) fixation. During a 9-week collection period, the ureide content varied from 9.0 to 69.2% of the xylary N. Between 9 and 11 weeks (early pod fill), there was a good correlation (r = 0.93) between C(2)H(2) reduction and ...

Glycosyl ureides in ruminant nutrition [PDF]
British Journal of Nutrition, 1982 1. Glucosyl urea, lactosyl urea and galactosyl urea were prepared from pure sugars and urea and their purity confirmed by determination of their melting points, specific rotations and by mass spectrometry.2. Using whey as a lactose source, a range of conditions were examined for the preparation of lactosyl urea on a laboratory scale. Yields of 60% were

Acta Agriculturae Slovenica, 2022 Ureidic legumes such as common bean (Phaseoulus valgaris L.) plants export nitrogen from the nodules to shoots and leaves as ureides during symbiotic biological nitrogen fixation. Common bean gene encoding allantoinase (allantoin amidohydrolase, EC 3.5.2.

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
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.

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

Nitrogen, 2022 Nitrate concentration is variable in soils, so the absorbed N from roots in a high-nitrate site is recycled from shoots to the root parts in N-poor niche. In this report, the absorption, transport, and recycling of N derived from 15N-labeled nitrate were

Frontiers in Agronomy, 2022 To evaluate cowpea genotypic differences in response to inoculation with Bradyrhizobium sp. strains BR 3267 and CB756 in the field, 15 genotypes were assessed for N2 fixation using 15N natural abundance and assays of xylem N solutes (ureides, nitrates ...
