Urea is widely used as a crop fertilizer because of its low cost. However, how this organic
compound is absorbed and assimilated by plants is still poorly characterized. This chapter …

Urea is a plant metabolite derived either from root uptake or from catabolism of arginine by
arginase. In agriculture, urea is intensively used as a nitrogen fertilizer. Urea nitrogen enters …

Urea is the major nitrogen (N) form supplied as fertilizer in agriculture, but it is also an
important N metabolite in plants. Urea transport and assimilation were investigated in …

Leguminous plants continuously recycle nitrogenous compounds from the nodules to the
aerial parts of the plants through the xylem stream in the form of ureides, allantoin and …

Urea is the most used nitrogenous fertilizer worldwide and an important nitrogen‐containing
plant metabolite. Despite its major use as fertilizer, its direct uptake is limited due to the …

Urea is ubiquitous in natural environments and serves as a readily available nitrogen (N)-
source for the growth of many organisms, including plants. It is synthesized during the …

Despite its extensive use as a nitrogen fertilizer, the role of urea as a directly accessible
nitrogen source for crop plants is still poorly understood. So far, the physiological and …

The symbiosis between α nitrogen (N 2)-fixing Proteobacteria (family Rhizobiaceae) and
legumes belonging to the Fabaceae (a single phylogenetic group comprising three …

Background Despite its extensive use as a nitrogen fertilizer, the role of urea as a directly
accessible nitrogen source for crop plants is still poorly understood. So far, the physiological …

Rice (Oryza sativa) production relies strongly on nitrogen (N) fertilization with urea, but the
proteins involved in rice urea metabolism have not yet been characterized. Coding …
