The ureides allantoin and allantoate are the main organic nitrogen compounds transported in several legumes, predominantly from N2 fixation. Moreover, recent studies point out a remarkable role for allantoin during several ...

Nitrogen is frequently the limiting mineral nutrient for plant productivity and it is essential to obtain an understanding of how this element is assimilated and its metabolism regulated, in crop plants. The objective of ...

Allantoin, a metabolite generated in the purine degradation pathway, was primarily considered an intermediate for recycling of the abundant nitrogen assimilated in plant purines. More specifically, tropical legumes utilize ...

Plants can respond and adapt to changes in the internal content of carbon and nitrogen by using organic compounds that widely differ in their carbon/nitrogen ratio. Among them, the amides asparagine and glutamine are ...

Legume plants from Fabaceae family (phylogenetic group composed by three subfamilies: Caesalpinioideae, Mimosoideae, and Papilionoideae) can fix atmospheric nitrogen (N2) into ammonia (NH3) by the symbiotic relationship ...

Soil waterlogging is a common problem in some agricultural areas, including regions under soybean (Glycine max) cultivation. In waterlogged soils, soil O2 depletion occurs due to aerobic microorganisms and plants, affecting ...

Allantoin is a purine oxidative product involved in long distance transport of organic nitrogen in nodulating legumes and was recently shown to play a role in stress tolerance in other plants. The subcellular localization ...

La soya [Glycine max (L.) Merr.] establece simbiosis con bacterias fijadoras del nitrógeno del grupo de los rizobios, específicamente del género Bradyrhizobium sp. El nitrógeno fijado en el nódulo es transferido hacia las ...
