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 ...
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 ...
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.
Plant breeders use different methods depending on the mode of reproduction of crops, which include: Self-fertilization, where pollen from a plant will fertilise reproductive cells or ovules of the same plant; Cross-pollination, where pollen from one plant can only fertilize a different plant
ABC model of flower development guided by three groups of homeotic genes.. The ABC model of flower development is a scientific model of the process by which flowering plants produce a pattern of gene expression in meristems that leads to the appearance of an organ oriented towards sexual reproduction, a flower.
Technological advances have now provided DH protocols for most plant genera. The number of species amenable to doubled haploidy has reached a staggering 250 in just a few decades. Response efficiency has also improved with gradual removal of species from recalcitrant category. Hence it will provide greater efficiency of plant breeding.
Often subject to less stringent regulatory oversight due to the lack of use of a DNA repair template and equivalence to conventional breeding techniques (in the case of plant breeding). SDN2 = one or several specific mutations have been introduced into the target gene at the SDN cut-site through use of a homology-repair template (hence this is ...
Bioprospecting (also known as biodiversity prospecting) is the exploration of natural sources for small molecules, macromolecules and biochemical and genetic information that could be developed into commercially valuable products for the agricultural, [2] [3] aquaculture, [4] [5] bioremediation, [4] [6] cosmetics, [7] [8] nanotechnology, [4] [9] or pharmaceutical [2] [10] industries.
