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

In agricultural cropping systems, relatively large amounts of nitrogen (N) are applied for
plant growth and development, and to achieve high yields. However, with increasing N …

The mineral nutrient needed in greatest abundance by plants is nitrogen. Plants, however,
must compete for nitrogen in the soil with abiotic and biotic processes such as erosion …

▪ Abstract Nitrogen assimilation is a vital process controlling plant growth and development.
Inorganic nitrogen is assimilated into the amino acids glutamine, glutamate, asparagine, and …

An analysis of changes in global gene expression patterns during developmental leaf
senescence in Arabidopsis has identified more than 800 genes that show a reproducible …

Lignin is a polymer of aromatic subunits usually derived from phenylalanine. It serves as a
matrix around the polysaccharide components of some plant cell walls, providing additional …

Amino acids are not only a nitrogen source that can be directly absorbed by plants, but also
the major transport form of organic nitrogen in plants. A large number of amino acid …

Biosphere nitrogen is subjected to rapid turnover, and because it is eventually lost as
nitrogen into the atmosphere, its maintenance requires continuous replenishment with …

Serine (Ser) has a fundamental role in metabolism and signaling in living organisms. In
plants, the existence of different pathways of Ser biosynthesis has complicated our …

Tryptophan is the one of the least abundant yet, in terms of energy, one of the most
expensive to produce of the standard protein amino acids (Hrazdina and Jensen, 1992). The …
