N2 Fixation (C2H2) and Ureide Content of Soybeans: Ureides as an Index of Fixation¹

Crop Science, 1983
The ureide contents of soybeans [Glycine max (L.) Merr.] were measured to determine if ureide concentration is a useful indicator of N2 fixation. Acetylene reduction activity (ARA) excised roots and the concentrations of ureides in stem segments were measured in field grown soybeans at weekly intervals. Ureides occurred in every soybean cultivar tested.

Purine-Derived Ureides Under Drought and Salinity

2017
Abstract Purine-derived ureides (allantoin and allantoate) are the dominant nitrogenous (N) products transported from the root nodules to the aerial plant organs by rhizobia-nodulated (Rh + ) ureidic legumes. However, ureides are not exclusively synthesized in Rh + legumes as some evidence suggest a more universal ureide metabolism in C3 and C4 ...

Walking on the ureide pathway

2010
Le ureidi, allantoina e allantoato, sono delle molecole ricche di azoto che derivano dal catabolismo delle purine. Alcuni organismi come uccelli, insetti e molti primati tra cui l’uomo eliminano l’eccesso di azoto sotto forma di acido urico, mentre per altri organismi il recupero degli atomi di azoto contenuti nelle purine può essere di vitale ...
