Amino acids have various prominent functions in plants. Besides their usage during protein
biosynthesis, they also represent building blocks for several other biosynthesis pathways …

Nitrogen is a limiting resource for plant growth in most terrestrial habitats since large
amounts of nitrogen are needed to synthesize nucleic acids and proteins. Among the 21 …

We present the 1.06 Gb sequenced genome of Gastrodia elata, an obligate
mycoheterotrophic plant, which contains 18,969 protein-coding genes. Many genes …

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 …

Expression of miR398 is induced in response to copper deficiency and is involved in the
degradation of mRNAs encoding copper/zinc superoxide dismutase in Arabidopsis thaliana …

Urease, the first enzyme to be crystallized, contains a dinuclear nickel metallocenter that
catalyzes the decomposition of urea to produce ammonia, a reaction of great agricultural …

Nickel is an essential catalytic cofactor of enzymes found in eubacteria, archaebacteria,
fungi, and plants. 1-6 These enzymes catalyze a diverse array of reactions that include both …

We propose experimental strategies to expand our understanding of the role of Ni in plants,
beyond the Ni-metallocenter of urease, still the only identified Ni-containing plant enzyme …

The basic leucine (Leu) zipper (bZIP) proteins compose a family of transcriptional regulators
present exclusively in eukaryotes. The bZIP proteins characteristically harbor a bZIP domain …

The broad distribution of ureases in leguminous seeds, as well as the accumulation pattern
of the protein during seed maturation, are suggestive of an important physiological role for …
