A rice XANTHINE DEHYDROGENASE gene regulates leaf senescence and response to abiotic stresses

Crop Journal, 2022
Xanthine dehydrogenase, a member of the molybdenum enzyme family, participates in purine metabolism and catalyzes the generation of ureides from xanthine and hypoxanthine.

Silicon and Nitrate Differentially Modulate the Symbiotic Performances of Healthy and Virus-Infected Bradyrhizobium-nodulated Cowpea (Vigna unguiculata), Yardlong Bean (V. unguiculata subsp. sesquipedalis) and Mung Bean (V. radiata)

Plants, 2017
The effects of 2 mM silicon (Si) and 10 mM KNO3 (N)—prime signals for plant resistance to pathogens—were analyzed in healthy and Cowpea chlorotic mottle virus (CCMV) or Cowpea mild mottle virus (CMMV)-infected Bradyrhizobium-nodulated cowpea, yardlong ...

Carbon dioxide level and form of soil nitrogen regulate assimilation of atmospheric ammonia in young trees. [PDF]

, 2015
The influence of carbon dioxide (CO2) and soil fertility on the physiological performance of plants has been extensively studied, but their combined effect is notoriously difficult to predict.

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.

Comparison of pepck gene expression in developing seeds and leaves of chickpea (Cicer arietinum L.) plant [PDF]

Journal of Cell and Molecular Research, 2009
Phosphoenolpyruvate Carboxykinase, encoded by the pepck gene, plays an important role in gluconeogenesis. It also seems to be important in metabolism of nitrogenous compounds in developing seeds of legumes, including amides and ureides which are then ...

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 ...

Highly dynamic cellular-level response of symbiotic coral to a sudden increase in environmental nitrogen [PDF]

, 2013
Metabolic interactions with endosymbiotic photosynthetic dinoflagellate Symbiodinium spp. are fundamental to reefbuilding corals (Scleractinia) thriving in nutrient-poor tropical seas.

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 ...
