Seed Yield and Nitrogen Efficiency in Oilseed Rape After Ammonium Nitrate or Urea Fertilization
Frontiers in Plant Science, 2021 In agricultural plant production, nitrate, ammonium, and urea are the major fertilized nitrogen forms, which differ in root uptake and downstream signaling processes in plants. Nitrate is known to stimulate cytokinin synthesis in roots, while for urea no

Direct uptake of soil nitrogen by mosses [PDF]
Biology Letters, 2006 Abstract Mosses are one of the most diverse and widespread groups of plants and often form the dominant vegetation in montane, boreal and arctic ecosystems. However, unlike higher plants, mosses lack developed root and vascular systems, which is thought to limit their access to soil nutrients.

Modelling diverse root density dynamics and deep nitrogen uptake — a simple approach [PDF]
, 2009 We present a 2-D model for simulation of root density and plant nitrogen (N) uptake for crops grown in agricultural systems, based on a modification of the root density equation originally proposed by Gerwitz and Page in J Appl Ecol 11:773–781, (1974). A

Overexpression of OsMYB305 in Rice Enhances the Nitrogen Uptake Under Low-Nitrogen Condition
Frontiers in Plant Science, 2020 Excessive nitrogen fertilizer application causes severe environmental degradation and drives up agricultural production costs. Thus, improving crop nitrogen use efficiency (NUE) is essential for the development of sustainable agriculture.

Dynamics of the nitrogen uptake by spring barley at injection application of nitrogen fertilizers
Plant, Soil and Environment, 2013 Influence of CULTAN system (controlled uptake long term ammonium nutrition) on the nitrogen uptake by spring barley (Hordeum vulgare L.) was observed at 5-year small-plot field experiments under conditions of the Czech Republic (central Europe). Nitrogen

SOME WHEAT VARIETIES RESPONSE TO NITROGEN FERTILIZATION LEVELS AND ITS EFFECT ON N-UPTAKE [PDF]
Journal of Soil Sciences and Agricultural Engineering, 2011 A field experiment was conducted at Sakha Agricultural Research Station farm, Kafr El-Sheikh Governorate, Egypt during 2008/2009 winter season, to assess response of some wheat (Triticum aestivum L.) varieties to the nitrogen fertilization levels by ...

Regulation of Copper Metabolism by Nitrogen Utilization in Saccharomyces cerevisiae
Journal of Fungi, 2021 To understand the relationship between carbon or nitrogen utilization and iron homeostasis, we performed an iron uptake assay with several deletion mutants with partial defects in carbon or nitrogen metabolism. Among them, some deletion mutants defective

Advances in understanding of nitrogen (N) uptake by plant roots
, 2021 Efficient use of nitrogen (N) by plants and particularly crops, is of global importance. In agriculture, high crop yields and protein content depend upon extensive N-inputs, however fertilizer N is costly to the farmer, and overuse can be damaging to the
