Transgenic plants are plants in which a copy of a modified and desired gene(DNA) has been introduced into the plant’s cell.
Transgenic plants will be plants that have had their genomes changed through hereditary designing strategies either by the expansion of an unfamiliar quality or expulsion of a specific hindering quality.
An unfamiliar quality embedded into a plant can be of alternate animal varieties or even realm. The first transgenic plant was created through the addition of nptII bacterial anti-microbial obstruction quality into tobacco.
From that point forward, with the fast advancement in plant sub-atomic science and hereditary designing innovation, a wide assortment of transgenic plants with significant agronomic qualities, for example, bother obstruction and dry spell resilience have been created, going from dicots to monocots that are agreeable to hereditary alterations.
The fundamental reason for the creation of transgenic plants is to deliver crops, which have ideal attributes, quality, and high return. Other than being useful to the agribusiness area, the plants are viewed as ready to go about as the plant for drug-protein creation
Getting new genes into plants
- USING AGROBACTERIUM
The most effective method of transferring desired genes into plants cell is by using the soil bacterium Agrobacterium tumefaciens as a vector. The bacterium contains a plasmid that can be used to carry the desired gene. It has negative effects on lower plants like monocots so, they are mostly used on dicotyledonous plants. The agrobacterium is inserted into the plants through cut wounds and it stimulates host cells to multiply rapidly, forming large cells called Galls(GALL DISEASE) Which are tumours.
This gall cell is capable of growing independently of the rest of the pants like cancer from the cut openings which is a completely different case from that of a normal wounded plants tissue which will release a chemical call callus due to chemicals released from the wounded part which rapidly stimulates the repair of the cut part. Chemicals released by the wounded cells also stimulates agrobacterium to infect the wound thereby stimulating the development of the gall
