Genotypic variation in response to drought stress is associated with biochemical and transcriptional regulation of ureides metabolism in common bean (Phaseolus vulgaris L.)

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.

Black Seedcoat Pigmentation Is a Marker for Enhanced Nodulation and N2 Fixation in Bambara Groundnut (Vigna Subterranea L. Verdc.) Landraces

Frontiers in Agronomy, 2021
Field studies on the effect of differing seedcoat colour on plant growth and symbiotic performance of three Bambara groundnut landraces using the 15N natural abundance technique and ureide analysis in the xylem stream and petiole extracts revealed a ...

N Absorption, Transport, and Recycling in Nodulated Soybean Plants by Split-Root Experiment Using ¹⁵N-Labeled Nitrate

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

Cowpea Genotypic Variations in N2 Fixation, Water Use Efficiency (δ13C), and Grain Yield in Response to Bradyrhizobium Inoculation in the Field, Measured Using Xylem N Solutes, 15N, and 13C Natural Abundance

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 ...

Ureide Permease 5 (AtUPS5) Connects Cell Compartments Involved in Ureide Metabolism [PDF]

Plant Physiology, 2019
Allantoin is a purine oxidative product involved in long distance transport of organic nitrogen in nodulating legumes and was recently shown to play a role in stress tolerance in other plants. The subcellular localization of enzymes that catalyze allantoin synthesis and degradation indicates that allantoin is produced in peroxisomes and degraded in the

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.

Gastrointestinal handling of glycosyl [13C]ureides [PDF]

European Journal of Clinical Nutrition, 2003
Lactose [(13)C]ureide has been proposed as a noninvasive marker for oro-caecal transit time in adults and children. The present study investigates the handling of lactose [(13)C]ureide ((13)C LU) and glucose [(13)C]ureide ((13)C GU) by the gastrointestinal tract and describes the metabolic fates of these substrates and describes the extent of tracer ...

Update on ureide degradation in legumes [PDF]

Journal of Experimental Botany, 2005
Warm season N2-fixing legumes move fixed N from the nodules to the aerial portions of the plant primarily in the form of ureides, allantoin and allantoate, oxidation products of purines synthesized de novo in the nodule. Ureides are also products of purine turnover in senescing tissues, such as seedling cotyledons.

Physiological and N2-fixation-related traits for tolerance to drought in soybean progenies [PDF]

Pesquisa Agropecuária Brasileira, 2019
: The objective of this work was to evaluate six soybean (Glycine max) genotypes for physiological traits and biological nitrogen fixation in drought conditions, and their capacity for recovery after rewetting, based on yield components.

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
