assimilation in plants
Nitrogen assimilation Nitrogen assimilation is the formation of organic nitro- gen compounds like amino acids from inorganic nitrogen compounds present in the environment. Dictionary ! Plants primarily take up Se as selenate or selenite (reviewed in Terry et al., 2000), which is metabolized, via the sulfur (S) assimilation pathway, resulting in the production of selenocysteine (SeCys; Ng and Anderson, 1978), selenomethionine and other Se isologs of … No specialization of function has yet been ascribed to the APS sulfotransferase isoenzymes. "Nitrogen Assimilation in the Highly Salt- and Boron-Tolerant Ecotype Zea mays L. Amylacea" Plants 9, no. 20 PHOTOSYNTHESIS AND CO2 ASSIMILATION PHOTOSYNTHESIS. Overexpression of T5120 in Arabidopsis promoted the response to nitrate, enhanced nitrate assimilation and improved biomass and root development. But all plants require nitrogen because it has a role to play in the general metabolism. (cross-section) Water and nutrients must pass through at least one cell on the way to the ... PHOTOSYNTHESIS AND CO2 ASSIMILATION GENERAL OBSERVATIONS. The following article is from The Great Soviet Encyclopedia (1979). Therefore nitrogen at what ever form it is present … When one considers that sulfur in plants is only 3% to 5% as abundant as nitrogen, it is perhaps understandable that sulfur assimilation has been less well studied Sulfur is one of the six macronutrients required by plants and is found in the amino acids Cys and Met and in a variety of metabolites.
3; Table 2; Lea and Miflin, 1974; Xu et al., 2012). The first volume: Sulfur Nutrition and Sulfur Assimilation in Higher Plants, edited by H. Rennenberg, C. Brunold, L.J. Photosynthetic carbon assimilation by plants is a key part the global carbon cycle and determines the availability of the food, fiber and fuel resources used by mankind. The third volume in the Plant Ecophysiology series integrates functional and molecular physiology with ecophysiological and sustainable agricultural approaches to get a better understanding of the regulation and the impact of environmental and stress signals on nitrogen acquisition and assimilation.
2001 Jan;25(1):93-102. doi: 10.1046/j.1365-313x.2001.00938.x. (2019) proposed that rising atmospheric CO2 concentrations "inhibit malate production in chloroplasts and thus impede assimilation of nitrate into protein of C3 plants, a phenomenon that will strongly influence primary productivity and food security under the environmental conditions anticipated during the next few decades". For instance, nitrate assimilation in plants is strongly regulated by phosphorylation. Nitrate assimilation is a key process for nitrogen (N) acquisition in green microalgae. The use of nitrogen by plants involves several steps, including uptake, assimilation, translocation and, when the plant is ageing, recycling and remobilization. 0. The positive relationship between the rate of CO 2 assimilation and p i /p a ( Fig. At elevated CO 2, CV ‐silenced rice plants maintained peroxisome proliferation and photorespiration and displayed higher N assimilation than wild‐type plants. Because of the strong influence of nitrogen-utilization efficiency on plant productivity, a vast amount of nitrogen fertilizers is poured onto fields to maximize crop yields (1–3).However, nitrogen fertilizers severely pollute the environment, especially the aquatic ecosystem (1–3). Organisms like plants, fungi and certain bacteria that cannot fix nitro- gen gas (N2) depend on the ability to assimilate nitrate or ammonia for their needs. noun. Assimilation is defined as to learn and comprehend. The concentration of nitrate in tissues is the balance … In water-stressed plants, leaf RWC was significantly lower than that of control plants. Among Chlorophyte algae, Chlamydomonas reinhardtii has resulted to be a good model system to unravel important facts of this process, and has provided important insights for agriculturally relevant plants.
