Journal ArticleDOI
Photooxidative destruction of chloroplasts and its effect on nuclear gene expression and extraplastidic enzyme levels
TL;DR: The events occurring during photodamage are described, the consequences for extraplastidic events are analyzed, and the implication of a plastsidic signal(s) in controlling the expression of nuclear genes which code for plastidics proteins are discussed.
Journal ArticleDOI
Regulation of spinach-leaf nitrate reductase by reversible phosphorylation.
TL;DR: Okadaic acid and microcystin prevented the rapid light-induced activation of nitrate reductase in intact spinach leaves and the role of reversible protein phosphorylation in regulation of light-coupled cytoplasmic metabolism is discussed.
Journal ArticleDOI
Absorption of atmospheric NO2 by spruce (Picea abies L. Karst.) trees
TL;DR: In this paper, the authors found that the NO2 flux to the leaves of spruce needles increased linearly with increasing NO2 concentrations, and that the internal resistances for NO2 influx can largely be explained by light dependent changes in shoot conductance.
Journal ArticleDOI
Ammonium can stimulate nitrate and nitrite reductase in the absence of nitrate in Clematis vitalba
Ralph A. Bungard,Astrid Wingler,James D. Morton,Mitchell Andrews,Malcolm C. Press,Julie D. Scholes +5 more
TL;DR: In this paper, Nitrate reductase (NR) activity dramatically increased in shoot tissue, and particularly leaf tissue, to up to three times the maximum level achieved in NO3- supplied plants.
Journal ArticleDOI
Phytochrome-mediated light regulation of nitrate reductase expression in squash cotyledons.
TL;DR: In etiolated squash (Cucurbita maxima L.) cotyledons, nitrate-inducible NADH:nitrate reductase activity and protein were increased in darkness by red light pulses with red/far-red photoreversibility, and it was found that after nitrate triggering, nitrates reduct enzyme expression appears to be regulated by light via phytochrome.

Journal ArticleDOI
The Assimilatory Nitrate-Reducing System and its Regulation
TL;DR: The present study focuses on the application of NAD(P)H-nitrate reductase to the reduction of Nitrite to Nitrite and the role of ferredoxin in this process.
Journal ArticleDOI
The partitioning of nitrate assimilation between root and shoot of higher plants
TL;DR: It is proposed that a greater proportion of nitrate assimilation occurs in the shoot when an increase in the rate of nitrates uptake does not induce an increaseIn NR level in the root, and a greaterportion of the nitrate taken up remains unassimilated and is passed into the xylem.

Nitrogen Metabolism in Roots

TL;DR: The role of GS and GDH in the SYNTHESIS of AMINO ACIDS and the source of reduction ANT are discussed.
Journal ArticleDOI
Expression of nuclear genes as affected by treatments acting on the plastids.
TL;DR: A signal from the plastids is essential for the expression of nuclear genes involved in plastidogenesis and is required continually, but a certain developmental stage of theplastid must be reached before the signal is released by the plASTid.
Journal ArticleDOI
Nitrate Uptake by Dark-grown Corn Seedlings: Some Characteristics of Apparent Induction.
TL;DR: The data suggest that development of the maximal accelerated rate of nitrate uptake depended upon continuous protein synthesis, and the hypothesis that synthesis of a specific nitrate transport protein must occur is advanced.
