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 …

In higher plants, two types of nitrate transporters, NRT1 and NRT2, have been identified. In
Arabidopsis, there are 53 NRT1 genes and 7 NRT2 genes. NRT2 are high-affinity nitrate …

We have devised an approach for analyzing shotgun proteomics datasets based on the
normalized spectral abundance factor that can be used for quantitative proteomics analysis …

IN mammals, active transport of organic solutes across plasma membranes was thought to
be primarily driven by the Na+ gradient1–3. Here we report the cloning and functional …

Besides industrially produced gibberellins (GAs), Fusarium fujikuroi is able to produce
additional secondary metabolites such as the pigments bikaverin and neurosporaxanthin …

Mouse embryonic stem (ES) cells differentiate into cells of all three primary germ layers
including endodermal cells that produce insulin in vitro. We show that constitutive …

In mammalian small intestine, a H+-coupled peptide transporter is responsible for the
absorption of small peptides arising from digestion of dietary proteins. Recently a cDNA …

Heterologous complementation of yeast mutants has enabled the isolation of genes
encoding several families of amino acid transporters. Among them, NTR1 codes for a …

One of the major bottlenecks in lactic acid production using microbial fermentation is the
detrimental influence lactic acid accumulation poses on the lactic acid producing cells. The …

Here we report the cloning and functional characterization of a rat novel peptide/histidine
transporter (PHT1), which was expressed in the brain and the retina. The cDNA encodes the …
