Markers and signals associated with nitrogen assimilation in higher plants.
A key concept underpinning current understanding of the carbon/nitrogen (C/N) interaction in plants is that the capacity for N assimilation is aligned to nutrient availability and requirements by the integrated perception of signals from hormones, nitrate, sugars, organic acids, and amino acids. Studies on the nature and integration of these signals over the last ten years has revealed a comple...
متن کاملRegulation of sulfur assimilation in higher plants: a sulfate transporter induced in sulfate-starved roots plays a central role in Arabidopsis thaliana.
Proton/sulfate cotransporters in the plasma membranes are responsible for uptake of the environmental sulfate used in the sulfate assimilation pathway in plants. Here we report the cloning and characterization of an Arabidopsis thaliana gene, AST68, a new member of the sulfate transporter gene family in higher plants. Sequence analysis of cDNA and genomic clones of AST68 revealed that the AST68...
متن کاملSubsystem: Inorganic sulfur (sulfate) assimilation
Introduction Sulfur is required for the biosynthesis of several essential compounds like amino acids (cysteine and methionine), vitamins (biotin, thiamin), and prosthetic groups (Fe-S clusters) in all organisms. In order to synthesize these compounds, the sulfur has usually to be in a reduced state, most commonly as (hydrogen) sulfide. In the absence of an environmental supply of reduced sulfur...
متن کاملSulphate Assimilation in Higher Plants: A Thioredoxin-Dependent PAPS-Reductase from Spinach Leaves
Higher plant leaf protein was investigated for the enzyme activity catalyzing a thioredoxindependent reduction of 3'-phosphoadenylylsulphate (PAPS) to sulphite. The enzyme became detectable when heterologous thioredoxin from Escherichia coli was used substituting for the hitherto unidentified plant thioredoxin. The enzyme's cross-reactivity with heterologous thioredo xin enabled the partial pu...
