Urease Is Not Essential for Ureide Degradation in Soybean [PDF]
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 ...

Enzymes of Ureide Synthesis in Pea and Soybean [PDF]
Soybean (Glycine max) and pea (Pisum sativum) differ in the transport of fixed nitrogen from nodules to shoots. The dominant nitrogen transport compounds for soybean are ureides, while amides dominate in pea. A possible enzymic basis for this difference was examined.The level of enzymes involved in the formation of the ureides allantoin and allantoic ...

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]
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

Nitrogen transport in the orchid mycorrhizal symbiosis - further evidence for a mutualistic association. [PDF]
Mycorrhizas are symbioses integral to the health of plant-based ecosystems (Smith & Read, 2008). In a typical mycorrhizal association, fungi in, or on, plant roots pass soil-acquired inorganic nutrients and water to the plant host.

Bradyrhizobium sp. enhance ureide metabolism increasing peanuts yield
This study aimed to evaluate the effects of seed inoculation with Bradyrhizobium sp. and co-inoculation with Azospirillum brasilense. The seed treatments were as follows: control (without inoculation); A. brasilense (2 mL per kg-1 of seed); A. brasilense (4 mL per kg-1 of seed); Bradyrhizobium sp. (2 mL per kg-1 of seed); Bradyrhizobium sp.
