Plant Breeding and Biotechnology

Plant Breeding and Biotechnology

Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.

Resistivity

Resistivity

When a voltage is applied to a conductor, an electrical field is generated, and charges in the conductor feel the force due to the electrical field. The current density that results depends on the electrical field and the properties of the material. In some materials, including metals at a given temperature, the current density is approximately proportional to the electrical field. In these cases, the current density can be modeled as:

Resistance

Resistance

When a current moves through any conductor, the conductor causes some level of difficulty for the current to flow. The measure of that difficulty is known as the resistance of the material and is represented by R. Every material has its own resistance. In the case of conductors, heat is emitted whenever a current passes through them. Resistance depends on the resistivity of the material. Resistivity is a characteristic of the material used to fabricate electrical components, whereas the...

Equivalent Resistance

Equivalent Resistance

In circuit analysis, situations often arise where resistors are neither in series nor parallel configurations. To tackle such scenarios, three-terminal equivalent networks like the wye (Y) (Figure 1 (a)) or tee (T) and delta (Δ) (Figure 1 (b)) or pi (π) networks come into play. These networks offer versatile solutions and are frequently encountered in various applications, including three-phase electrical systems, electrical filters, and matching networks.

Resistance and Conductance

Resistance and Conductance

A conductor's DC resistance at a given temperature is influenced by its resistivity, length, and cross-sectional area. Resistivity is an inherent property of the conductor material, with annealed copper serving as the international standard for measurement. For instance, the resistivity of hard-drawn aluminum at 20 degrees Celsius is 61% of the standard conductivity of annealed copper.
Various factors impact the resistance of a conductor. Spiraling in stranded conductors increases their...

Rolling Resistance

Rolling Resistance

When a solid cylinder rolls steadily on a rigid surface, the normal force applied by the surface on the cylinder is perpendicular to the tangent at the contact point. However, since no materials are entirely rigid, the surface's reaction to the cylinder involves a range of normal pressures.
For instance, imagine a hard cylinder rolling on a comparatively soft surface. The cylinder's weight compresses the surface beneath it. As the cylinder moves, the material in front of it slows down due to...

Background:

Soybean rust, caused by Phakopsora pachyrhizi, is a major threat to global soybean production, causing yield losses exceeding 50% under conducive conditions.
The pathogen infects numerous legumes and exhibits diverse physiological races, complicating resistance strategies.
Existing single-gene resistance sources have shown variable efficacy against different Phakopsora pachyrhizi isolates.

Purpose of the Study:

To proactively evaluate the USDA soybean germplasm collection for resistance to soybean rust.
To identify soybean lines exhibiting enhanced yield stability and novel sources of single and partial resistance.
To contribute to the long-term management strategies for soybean rust.

Main Methods:

Screening of the USDA soybean germplasm collection for rust resistance.
Evaluation of soybean lines for yield stability under rust pressure.
Utilizing data from field trials at multiple international locations and a biocontainment facility.

Main Results:

Identification of soybean lines with improved yield stability in the presence of rust.
Discovery of additional sources of single and partial resistance to Phakopsora pachyrhizi.
Understanding the variability in pathogen response across different soybean genotypes and isolates.

Conclusions:

Fungicides remain the primary immediate defense against soybean rust.
Host resistance and yield stability are crucial for sustainable, long-term soybean rust management.
Continued germplasm evaluation is essential for developing resilient soybean cultivars.
