Agrobacterium: 59 фото и видео

The ability of Agrobacterium to transfer genes to plants and fungi is used in biotechnology, in particular, genetic engineering for plant improvement. Genomes of plants and fungi can be engineered by use of Agrobacterium for the delivery of sequences hosted in T-DNA binary vectors.

Disadvantages include: (i) the need for long tissue culture periods to recover transgenic plants, (ii) low frequency of stably transformed plants, (iii) the narrow range of genotypes within a crop species that can be transformed, and (iv) the host-range limitations of certain Agrobacterium species.

Agrobacterium tumefaciens is a pathogenic bacterium that causes crown gall disease, a plant tumor affecting a wide range of plant species. Crown galls develop upon transfer of a portion of the tumor-inducing (Ti) plasmid, the transfer-DNA (T-DNA), into the genome of the bacterium's plant hosts (Chilton et al., 1980).

Gram-negative. Agrobacterium tumefaciens is a Gram-negative soil bacterium with the ability to infect plants by delivering a specific segment of its genome to the nuclei of susceptible plant cells.

Agrobacterium is responsible for opportunistic infections in humans with weakened immune systems. It is also found to be responsible for producing poisonous hydrogen sulfide (H2S) gas, sepsis, monoarticular arthritis, bacteraemia, cancer, Morgellons disease and so on, in humans.
