A probable pathway of ureide assimilation in pigeon pea pods [PDF]

, 1983
Ureides (allantoin and allantoic acid) and the activities of glutamine synthetase, glutamate dehydrogenase, uricase. allantoinase and urease, the enzymes presumbly involved in the assimilation of ureides, were determined both in the vegetative organs and

Allantoin accumulation in response to increased growth irradiance in Arabidopsis thaliana

Biologia Plantarum, 2018
Excess radiation is one of frequent natural environmental stresses that plants have to cope with on a daily basis. Therefore, plants have evolved many short- and long-term mechanisms to acclimate to high irradiance and tolerate it.

Absorption and Transport of Phosphorus in Nodulated Soybean Plants and Diagnosis of Phosphorus Status Using Xylem Sap Analysis

Agriculture
Phosphorus (P) is an essential major element for plants. The absorption and transport of P are important for soybean growth and yield, including nodule growth and N2 fixation. Through an analysis of xylem sap, we investigated how nodulated soybean plants

Disruption of ureide degradation affects plant growth and development during and after transition from vegetative to reproductive stages

BMC Plant Biology, 2018
Background The ureides allantoin and allantoate are major metabolic intermediates of purine catabolism with high nitrogen-to-carbon ratios. Ureides play a key role in nitrogen utilization in ureide-type legumes, but their effects on growth and ...

Nitrate influences the metabolism of nitrogenous compounds in calopo (Calopogonium mucunoides) throughout the life cycle

Biotemas, 2014
In Calopogonium mucunoides, nitrogen metabolism was significantly altered between the various plant development stages. Throughout the life cycle, even in the presence of nitrate, the plant kept itself nodulated and high ureide concentrations were ...
