Nitrate assimilation in plants and related organisms is a highly regulated and conserved
pathway in which the enzyme nitrate reductase (NR) occupies a central position. Although …

Positive signaling by nitrate in its assimilation pathway has been studied in Chlamydomonas
reinhardtii. Among> 34,000 lines generated by plasmid insertion, 10 mutants were unable to …

Abstract The NAD (P) H nitrate reductase (NR) from Chlamydomonas reinhardtii is encoded
by the structural gene Nia1. Numerous data from the literature indicate that this enzyme is …

Nitrate reductase (NR) is the enzyme that catalyzes the first step of nitrate assimilation. It is
well known that the expression of NR genes is rapidly induced in various plants by nitrate …

Nitrate signalling on the nitrate reductase (Nia1) gene promoter from Chlamydomonas
reinhardtii has been studied by using a construct of the Nia1 promoter transcriptionally fused …

The ability to use nitrate as sole nitrogen source to sustain growth is a property shared by
some bacteria and fungi and by most algae and plants. The biochemical pathway …

Nitrate from the soil is the main nitrogen source for most higher plants (Beevers & Hageman,
1969; Guerrero, Vega & Losada, 1981; Blevins, 1989). To increase both the growth and …

Nitrate and ammonium are major inorganic nitrogen sources for plants and algae. These
compounds are assimilated by means of finely regulated processes at transcriptional and …

Publisher Summary This chapter presents nitrogen assimilation in the context of genome
analysis and gene function, with particular emphasis on inorganic nitrogen transporters …

Nitrate reductase (NR), the first enzyme in the nitrate assimilation pathway, is regulated post-
transcriptionally in response to light and CO2. In spinach, it has been shown that …
