The plant genome continued to evolve through natural evolutionary processes. As a result of these changes plant species were completely different from their ancestors. These genetic modifications had several advantages:

These advantages showed scientists and breeders the advantage of modifying plant genomes. And encourage them to identify, select and analyze plants with improved characteristics to make crosses.

Typically, using traditional crossing techniques, it takes about 12 years to develop and release a new plant variety. In addition, these varieties must have and pass three criteria, including:

Green Biotech: Methods Of Genetic Engineering In Plants

Advances in technologies are to ensure that the process of creating new plant varieties takes less time and ensure that harmful traits are removed from plants.

In addition, the developed plants should be evaluated for any unwanted products and removed before they are introduced to the market. And, so far, many techniques have been successfully tested to ensure the creation of better and safer plant varieties.

A variety of genetic techniques are currently available to make desired changes in the gene sequence of plants. Some of them are covered in this section.

It is a soil-dwelling bacterium capable of infecting plants and integrating disease-causing DNA into the plant genome. The plant expresses the gene as its own, resulting in the formation of galls, and the disease is called crown gall disease.

Genetic Engineering In Plants: What It Is And Its Techniques?

The genome contains a gene region that forms views and causes crown gall disease in plants. Scientists replace this gene region with their desired gene sequence and insert it into the plant.

Strains become one of the most effective vehicles for introducing character-improving genes into plants and producing various commercial genetically modified crops.

The Agrobacterium transformation technique does not work in all plants and as a result, many other techniques have been introduced by scientists to accomplish the objective.

Microprojectile bombardment or gene gun or biolyst particle delivery systems are used to deliver naked DNA into plants by adhering microscopic particles. The technique has been tested in plants such as rice, corn and other grains.

Microscopic particles that act as carriers of DNA or RNA are either high-density gold microparticles or high-density tungsten microparticles. The helium pulse accelerates these pulses to such high speeds that they penetrate the cell wall and membrane and enter the cell.

The gene gun is not only used to transform genomic DNA but can also transform organelles such as plastids and mitochondria. This technique is also used for in vivo and in vitro gene expression and regulatory analysis.

In this technique, plant cells growing in culture medium are stripped of their walls, forming protoplasts (plant cells without cell walls). Then, the desired piece of DNA is delivered to the media and an electrical impulse is applied. This disrupts and destabilizes the plant protoplast, resulting in the entry of DNA into the cell.

Cells transformed using the technique then recover or regenerate walls and are grown into mature plants in tissue culture. However, the application of this technique is limited due to the poor efficiency of most plants in regenerating their cell walls.

Nanotechnology Strategies For Plant Genetic Engineering

In this method, glass micropipettes are used to inject the desired substance directly into the cell. A certain percentage of these cells will survive and incorporate DNA. However, it is labor intensive and inefficient compared to other methods.

Cells transformed using the technique are then grown using tissue culture for the final product and undergo several rounds of testing before commercial release of the recombinant plant.

The Truth About Genetically Modified Food

Again, pollution! Tissue culture is a long and laborious process and becomes a nuisance when fungi or bacteria attack our beautiful cultures. Growing cells in laboratories requires a lot… GM is a technique that involves inserting DNA into an organism’s genome. To create a GM plant, new DNA is transferred into plant cells. Typically, the cells are then grown in tissue culture where they grow into plants. The seeds produced by these plants will inherit the new DNA.

The characteristics of all living organisms are determined by their genetic makeup and its interaction with the environment. An organism’s genetic makeup is its genome, which is made up of DNA in all plants and animals. Genomes contain genes, regions of DNA that usually carry the instructions for making proteins. It is this protein that gives the plant its characteristics. For example, flower color is determined by genes that carry the instructions to make proteins involved in the production of the pigments that color the petals.

Plant genetic modification involves adding a specific piece of DNA to a plant’s genome, giving it new or different characteristics. This may include changing the way a plant grows or making it resistant to a particular disease. The new DNA becomes part of the genome of the GM plant, which will contain the seeds produced by the plant.

The first step in creating a GM plant requires transferring the DNA into the plant cell. One of the methods used to transfer DNA is to coat the surface of small metal particles with the relevant DNA fragment and bombard the particles into plant cells. Another method is to use bacteria or viruses. There are many viruses and bacteria that transfer their DNA into the host cell as a normal part of their life cycle. For GM plants, the most commonly used bacterium is called Agrobacterium tumefaciens. The gene of interest is transferred to the bacteria and the bacterial cells then transfer the new DNA into the genome of the plant cells. Plant cells that have successfully taken up the DNA are then grown to form a new plant. This is possible because individual plant cells have an impressive capacity to produce whole plants. In rare cases, the process of DNA transfer can occur without intentional human intervention. For example, sweet potatoes contain DNA sequences that were transferred from Agrobacterium bacteria to the sweet potato genome thousands of years ago.

How Does Gm Differ From Conventional Plant Breeding?

There are other ways to alter crop genomes, some of which are long established, such as mutational breeding, and others of which are new, such as genome editing, but in this Q&A we focus on GM as it is currently commonly defined. . For regulatory purposes in Europe. The goal of both GM and conventional plant breeding is to produce crops with improved characteristics by altering their genetic makeup. GM achieves this by adding a new gene or genes to the crop’s genome. Conventional breeding achieves this by crossing plants with relevant characteristics resulting from specific combinations of genes inherited from two parents and selecting offspring with the desired combination of characteristics.

Both conventional plant breeding and GM yield genetic crops. Genetic improvement has been a central pillar of improved agricultural productivity for thousands of years. This is because wild plants make very poor crops. Natural selection favors plants that can compete with neighboring plants for light, water, and nutrients, protect themselves from being eaten and digested by animals, and disperse their seeds over long distances. These characteristics are in direct conflict with the goals of agriculture, which require plants to invest as much of their resources as possible in producing nutritious, easily harvestable products for human consumption. Because of the stark contrast between what natural selection has produced and what makes a good crop, for thousands of years we have used traditional breeding methods to transform plants that compete well in the wild into plants that perform well in agriculture. The result is our modern crop varieties, which are much more productive and more nutritious than their wild ancestors, but which do not compete well in the wild.

Many genes are now known that can contribute to improving sustainable food production. In some cases there will be traditional reproduction
