Currently, there are several reports on standardisation of protocol for the Agrobacterium-mediated transformation. The effect of different parameters such as infection time, acetosyringone, DTT, and cysteine have been studied in soybean (Glycine max). [18] Possible plant compounds that initiate Agrobacterium to infect plant cells: [19]
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.
The EH stands for "Elizabeth Hood" and A for "Agrobacterium". The EHA101 helper strain is a derivative of A281, the hypervirulent A. tumefaciens strain that causes large, fast-growing tumors on solanaceous plants. [1] [2] This strain is used for moving genes of interest into many hundreds of species of plants all over the world.
Plant transformation vectors are plasmids that have been specifically designed to facilitate the generation of transgenic plants.The most commonly used plant transformation vectors are T-DNA binary vectors and are often replicated in both E. coli, a common lab bacterium, and Agrobacterium tumefaciens, a plant-virulent bacterium used to insert the recombinant DNA into plants.
A number of methods are available to transfer DNA into plant cells. Some vector-mediated methods are: Agrobacterium-mediated transformation is the easiest and most simple plant transformation. Plant tissue (often leaves) are cut into small pieces, e.g. 10x10mm, and soaked for ten minutes in a fluid containing suspended Agrobacterium. The ...
They are artificial vectors that have been derived from the naturally occurring Ti plasmid found in bacterial species of the genus Agrobacterium, such as A. tumefaciens. The binary vector is a shuttle vector, so-called because it is able to replicate in multiple hosts (e.g. Escherichia coli and Agrobacterium).
The main benefit of agroinfiltration when compared to the more traditional plant transformation is speed and convenience, although yields of the recombinant protein are generally also higher and more consistent. The first step is to introduce a gene of interest to a strain of Agrobacterium tumefaciens.
Agrobacterium-mediated T-DNA transfer is widely used as a tool in biotechnology.For more than two decades, Agrobacterium tumefaciens has been exploited for introducing genes into plants for basic research as well as for commercial production of transgenic crops. [11]
