Agrobacterium is a genus of Gram-negative bacteria established by H. J. Conn that uses horizontal gene transfer to cause tumors in plants. Agrobacterium tumefaciens is the most commonly studied species in this genus.
Genetically modified bacteria were the first organisms to be modified in the laboratory, due to their simple genetics. [1] These organisms are now used for several purposes, and are particularly important in producing large amounts of pure human proteins for use in medicine. [2]
Genetically modified organisms refers to any plant, animal or microorganism that has been genetically altered, due to modern biotechnology like genetic engineering. Often, GMOs are labeled “GE ...
A genetically modified organism (GMO) is any organism whose genetic material has been altered using genetic engineering techniques.The exact definition of a genetically modified organism and what constitutes genetic engineering varies, with the most common being an organism altered in a way that "does not occur naturally by mating and/or natural recombination". [1]
The first genetically modified animal to be commercialised was the GloFish, a Zebra fish with a fluorescent gene added that allows it to glow in the dark under ultraviolet light. [31] It was released to the US market in 2003. [32] The first genetically modified animal to be approved for food use was AquAdvantage salmon in 2015. [33]
Transgenic or genetically modified organisms, be they bacteria, viruses or fungi, serve many research purposes. Transgenic plants, insects, fish and mammals (including humans) have been bred. Transgenic plants such as corn and soybean have replaced wild strains in agriculture in some countries (e.g. the United States).

Selectable markers allow scientists to separate non-recombinant organisms (those which do not contain the selectable marker) from recombinant organisms (those which do); that is, a recombinant DNA molecule such as a plasmid expression vector is introduced into bacterial cells, and some bacteria are successfully transformed while some remain non-transformed.
