Journal of Agronomy and Crop Science, Volume 211, Issue 4, July 2025.ABSTRACT Soybean (Glycine max L.) forms a symbiotic relationship with compatible soil rhizobia, enabling biological nitrogen fixation. Among numerous factors, moisture deficit is a major challenge to soybean production due to its direct impact on the ability to fix nitrogen.

Cluster Bean—A Ureide- or Amide-Producing Legume? [PDF]
Plant Physiology, 1982 Xylem sap of cluster bean (Cyamopsis tetragonoloba L. cv FS-277) and pigeonpea (Cajanus cajan cv UPAS-120) were analyzed for total nitrogen, amide nitrogen, and ureide nitrogen at flowering stage. Nitrogenase, uricase, and allantoinase were compared in nodules of cluster bean and pigeonpea.

A pattern recognition study of acyclic ureide anticonvulsants
Journal of Pharmacy and Pharmacology, 1990 AbstractA pattern recognition structure-activity study employing topological, geometric and physicochemical descriptors was performed on 27 acyclic ureide anticonvulsants. Twelve numerical descriptors were used as variables in a discriminant function analysis which categorized the ureide analogues with respect to their bioactivity. The results from the

Urease Is Not Essential for Ureide Degradation in Soybean [PDF]
Plant Physiology, 1995 The hypothesis that soybean (Glycine max L. [Merrill]) catabolizes ureides to urea to a physiologically significant extent was tested and rejected. Urease-negative (eu3-e1/eu3-e1) plants were supported by fixed N2 or by 2 mM NH4NO3, so that xylem-borne nitrogen contained predominantly ureides (allantoin and allantoic acid) or amide amino acids ...

Plant-Environment Interactions, Volume 6, Issue 1, February 2025.Soybean plants exhibit overcompensation when exposed to both insect and drought stress. There are strong genotypic effects within genotypes that vary in wilting speeds. Fast‐wilting plants produced more seeds, but slow‐wilting plants produced higher‐quality seeds.

The use of LAC fusions to analyse the regulation of NOD gene region of Rhizobium loti : a thesis presented in partial fulfilment of the requirements for the Degree of Master of Science in genetics at Massey University, Palmerston North, New Zealand [PDF]
, 1990 Two approaches where used in the analysis of common and host specific nod gene expression in Rhizobium loti strains NZP2213 and NZP2037. The first approach using the Tn3-HoHol transposon to generate lacZ transcriptional/translational fusions, produced

Plant growth regulators induced urease activity in Cucurbita pepo L. cotyledons [PDF]
, 2016 This study is aimed to investigate the activity of urease (EC 3.5.1.5, urea amidohydrolase) that catalyzes the hydrolysis of urea in 5-day-old Cucurbita pepo cotyledons subjected to various concentrations of different growth regulators.
