The foliar incorporation of various reactive forms of nitrogen (N) has been identified and
studied for nearly 30 years. However, the ecosystem-level ramifications of this uptake …

Cyanobacteria are a very important group in aquatic systems, particularly in eutrophic
waters. Therefore studies about their success in the environment are essential. Many …

The specific activities of nitrate reductase, nitrite reductase, glutamine synthetase, glutamate
synthase, and glutamate dehydrogenase were determined in intact protoplasts and intact …

Although the effects of aluminum on the content and accumulation of mineral nutrients in
crops have been studied, but nothing is known about its effect on the nutritional efficiency of …

Background and Aims Uptake of heavy metals by plant root cells depends on electro-
physiological parameters of the plasma membrane. In this study, responses of the plasma …

Ocean acidification and eutrophication are two major environmental issues affecting kelp
mariculture. In this study, the growth, photosynthesis, and biochemical compositions of adult …

We compared the response of NO 3--induced nitrate-reductase (NR) and nitrite-reductase
(NIR) levels in virtually carotenoid-free far-red-light-grown mustard (Sinapis alba L.) …

Higher plants acquire nitrogen from the soil mainly in the form of nitrate and/or ammonium.
The two N sources are taken up by the roots, where part of the nitorgen can be utilized …

NADP-dependent non-phosphorylating D-glyceraldehyde-3-phosphate dehydrogenase (EC
1.2. 1.9), previously described in higher plants, has been now found to be present in …

Little effort has so far been made to decompose biological rhythms into their
physicochemical component processes [1]. Light-induced circadian rhythms in nitrate …
