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. As humans' understanding of genetics advanced, improved crop varieties could be achieved more quickly. Artificial selection could be more directed, and crop varieties enhanced for favorable traits more quickly to produce better, more robust, or more palatable plants.

Zebrafish Breeding and Embryo Handling

2023
Zebrafish (Danio rerio) are an important model organism that is particularly valuable for research in developmental biology. Zebrafish are extremely fertile and can produce hundreds of progeny per week, so it is relatively easy to collect a large number of embryos for high sample numbers. Furthermore, zebrafish undergo rapid development and embryos are transparent, allowing for easy visualization of developmental processes. This video covers the steps required for the collection of newly...

Worldwide, there are several large commercial breeding facilities that supply mice to research laboratories, but many facilities also choose to breed mice and rats in-house to reduce costs and increase research options. When breeding in the animal facility, researchers are able to manipulate the genetics of the...

All animal procedures described here must be conducted in accordance with institutional animal ethics guidelines and approved by IACUC. All procedures must follow the principles of the 3Rs—Replacement, Reduction, and Refinement—and must be performed by trained personnel. Breeding management supports the 3Rs by minimizing unnecessary animal production and ensuring that only the number of animals required for a study is generated. Effective breeding strategies help reduce surplus animals and...
FAQs
Biochemical assays connect visible plant performance with underlying biological processes. Measurements of protein composition, enzyme activity, and metabolite profiles can reveal differences in metabolism, development, stress responses, or nutritional characteristics that may not be apparent from phenotype alone. This added information helps breeders evaluate genetic variation more precisely and identify promising material earlier in crop improvement.
Phenotypic assessment focuses on observable plant characteristics, whereas biochemical assays measure components or activities associated with those characteristics. Molecular assays can examine markers linked to traits such as resistance and quality. Using these approaches together provides complementary evidence: visible performance shows how a plant expresses a trait, while biochemical or molecular measurements help relate that expression to inherited variation.
Selection is most useful when measured differences reflect inherited variation rather than observations limited to a particular plant or breeding population. Plant Breeding Screening therefore examines individuals, seeds, or populations for desirable characteristics and uses biochemical or molecular evidence alongside phenotype. This supports more informed identification of material that may contribute useful traits to later crop development.
A typical workflow begins by evaluating plants, seeds, or breeding populations, followed by phenotypic assessment and targeted biochemical or molecular measurements. Researchers may examine protein composition, enzyme activity, metabolite profiles, or markers associated with resistance and quality. The resulting information is used to identify promising individuals for selection, making the breeding process more focused and efficient.
Researchers use these measurements when crop improvement depends on traits connected to metabolism, development, stress responses, nutritional characteristics, resistance, or quality. Protein, enzyme, and metabolite data can help distinguish promising material within breeding populations, while relevant molecular markers provide additional evidence. Such screening is especially valuable when breeders want to select material earlier than phenotype-based evaluation alone allows.
In a biochemistry context, screening helps relate genetic variation to plant metabolism and other measurable biological characteristics. The information can guide selection for improved yield, disease resistance, environmental tolerance, nutritional value, or industrial value. By combining biochemical evidence with plant performance, researchers can better identify breeding material aligned with the intended crop improvement goal.
