Molecular breeding is the application of molecular biology tools, often in plant breeding [1] [2] and animal breeding. [3] [4] In the broad sense, molecular breeding can be defined as the use of genetic manipulation performed at the level of DNA to improve traits of interest in plants and animals, and it may also include genetic engineering or gene manipulation, molecular marker-assisted ...
Genetic engineering could potentially fix severe genetic disorders in humans by replacing the defective gene with a functioning one. [5] It is an important tool in research that allows the function of specific genes to be studied. [6] Drugs, vaccines and other products have been harvested from organisms engineered to produce them. [7]
Human-directed genetic manipulation began with the domestication of plants and animals through artificial selection in about 12,000 BC. [1]: 1 Various techniques were developed to aid in breeding and selection. Hybridization was one way rapid changes in an organism's genetic makeup could be introduced. Crop hybridization most likely first ...

[1] [2] [3] The general steps involve reducing the complexity of the genomic DNA with specific restriction enzymes, choosing diverse fragments to serve as representations for the parent genomes, amplify via polymerase chain reaction (PCR), inserting fragments into a vector to be placed as probes within a microarray, and then fluorescent targets ...
On the other hand, plants are still sufficiently closely related to animals and humans that they are able to correctly process and configure both animal and human proteins. Their seeds and fruits also provide sterile packaging containers for the valuable therapeutics and guarantee a certain storage life.
[3] [20] For example, DNA shuffling has been used to increase the potency of phage-displayed recombinant interferons on murine and human cells. [3] Additionally, the improvement of green fluorescent protein (GFP) was accomplished with DNA shuffling by molecular breeding as a 45-fold greater signal than the standard for whole cell fluorescence ...
Marker assisted selection or marker aided selection (MAS) is an indirect selection process where a trait of interest is selected based on a marker (morphological, biochemical or DNA/RNA variation) linked to a trait of interest (e.g. productivity, disease resistance, abiotic stress tolerance, and quality), rather than on the trait itself.
