Government’s guidelines to expedite the development of plant varieties, reduce approval time

Recently the government has issued guidelines to accelerate the development of plant varieties.

These guidelines will apply to all organizations involved in the research, development and management of genome-edited plants under the categories Site Directed Nuclease, SDN-1 and SDN-2.

  • The organizations are expected to accelerate the development of plant varieties and reduce the approval time.
  • Earlier, SDN-1 and SDN-2 categories of genome edited plants were exempted from certain strict regulations under the Environment (Protection) Act, 1986.
  • SDN technology helps to make special small changes in the DNA truncated sites. It involves targeted DNA truncation and taking advantage of the host’s natural repair mechanisms.
  • Such targeted edits result in the addition of a new and desired feature. For example, an increase in the amount of nutrients or a decrease in the production of allergy-causing substances.

Genome edited plants derived from SDN are generally classified into three categories:

  • SDN-1: This is site-directed mutagenesis (production of genetic mutations) without using a DNA sequence template.
  • SDN-2: It is a site-directed mutagenesis using a DNA sequence template
  • SDN-3: In this, site-directed entry of a gene DNA sequence is performed using a DNA sequence template.

In SDN-1 and SDN-2 no foreign DNA is introduced.

What is Genome Editing?

  • It is also called gene editing. It is a set of technologies. It changes the DNA/RNA of an organism.
  • In this way precise changes can be made to the target nucleotide/nucleotides in the DNA/RNA of an organism.

Application-

  • Crop variety can be improved,
  • The nutritional content of the crop can be increased,
  • Crops can be protected from pests and diseases,
  • Biofuels can be obtained,
  • It also helps in making medicine etc.
