Inorganic Nitrogen Assimilation

Inorganic Nitrogen Assimilation

Nitrogen is an essential element in biological systems, forming a crucial component of proteins, nucleic acids, and other cellular constituents. Many bacteria and archaea acquire nitrogen in the form of nitrate (NO₃⁻) or ammonia (NH₃), which are then assimilated into biomolecules through specific enzymatic pathways.Assimilatory Nitrate ReductionWhen nitrate enters the cell, it undergoes a two-step reduction process known as assimilatory nitrate reduction. Initially, the enzyme nitrate reductase...

Background and Environment Affect Phenotype

Background and Environment Affect Phenotype

Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

Wilcoxon Signed-Ranks Test for Median of Single Population

Wilcoxon Signed-Ranks Test for Median of Single Population

The Wilcoxon signed-rank test for the median of a single population is a nonparametric test used to evaluate whether the median of a population differs from a specified value. Unlike parametric tests, it does not require data to follow a normal distribution, making it suitable for non-normal or small samples. The test begins by calculating the difference (d) between each observation and the hypothesized median. The absolute values of these differences are ranked in ascending order, with ties...

Overview of Nitrogen Metabolism

Overview of Nitrogen Metabolism

Nitrogen is a very important element for life because it is a major constituent of proteins and nucleic acids. It is a macronutrient, and in nature, it is recycled from organic compounds and stored in the form of ammonia, ammonium ions, nitrate, nitrite, or nitrogen gas by many metabolic processes. Many of these metabolic processes are carried out only by prokaryotes.
The largest pool of nitrogen available in the terrestrial ecosystem is gaseous nitrogen (N2) from the air, but this nitrogen...

Overview of Metabolism

Overview of Metabolism

Living cells constantly carry out various chemical reactions which are necessary for their proper functioning. These reactions are interlinked to one another via multiple pathways. The collection of these chemical reactions is known as metabolism.
Plant Metabolism
Sunlight, the primary source of energy in plants, is first absorbed by the chlorophyll pigments present in their leaves. Plants then use this energy to carry out photosynthesis, where water is oxidized into oxygen and carbon dioxide...

Area of Science:

Agricultural Science
Plant Physiology
Genetics

Context:

Nitrogen is a crucial nutrient for wheat growth and yield.
Variability exists among wheat cultivars in nitrogen utilization efficiency (NUE).
Understanding NUE is vital for sustainable agriculture and optimizing fertilizer use.

Purpose:

To investigate genotypic differences in wheat for biomass production, nitrogen accumulation, and nitrogen production efficiency.
To identify and screen wheat genotypes with high nitrogen utilization efficiency.
To characterize the traits associated with high NUE in wheat.

Summary:

A pot experiment evaluated 130 wheat cultivars under uniform nitrogen supply, measuring biomass, nitrogen accumulation, and NUE at different growth stages.
Significant genotypic variations were observed in nitrogen dry matter production efficiency and grain yield production efficiency.
High NUE wheat genotypes exhibited traits like reduced ineffective tillers and enhanced nitrogen uptake and utilization, particularly before and during the heading and maturing stages.

Impact:

Identified specific wheat genotypes (Sheng CXK027-4, Liangmai 4) with superior nitrogen utilization capabilities.
Demonstrated that high NUE genotypes can achieve substantially higher grain yields and nitrogen accumulation compared to low NUE genotypes.
Provides a basis for breeding programs aimed at developing more nitrogen-efficient wheat varieties, contributing to reduced fertilizer input and environmental impact.
