Plant Breeding and Biotechnology

21.4K
Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.

Transgenic Plants

8.4K
Recombinant DNA technology called transgenesis is often used to add a foreign gene or remove a detrimental gene from an organism. Such genetically modified organisms are called transgenic organisms.
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...

Area of Science:

  • Agricultural Science
  • Genetics
  • Plant Biology

Background:

  • Cereal crops are vital global food and nutrition sources.
  • Abiotic stresses (drought, salinity, temperature extremes, heavy metals) significantly reduce cereal production.
  • Traditional breeding and transgenic methods have limitations in mitigating abiotic stress.

Purpose of the Study:

  • To review recent advancements in genome-editing technologies for improving cereal abiotic stress tolerance.
  • To highlight the application of CRISPR and other tools in developing resilient cereal cultivars.
  • To summarize progress in enhancing cereal traits for better yield under adverse conditions.

Main Methods:

  • Review of current literature on genome editing in cereals.
  • Focus on Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)/Cas9 technology.
  • Inclusion of newer techniques like prime editing and base editing.

Main Results:

  • Genome editing has revolutionized cereal crop improvement, particularly for abiotic stress tolerance.
  • CRISPR/Cas9 is widely adopted due to its efficiency, specificity, and flexibility.
  • Significant progress has been made in developing cereal genotypes with enhanced tolerance to various abiotic stresses.

Conclusions:

  • Genome editing offers powerful tools to develop climate-resilient cereal crops.
  • Improved cereal cultivars exhibit better performance and yield stability under stress.
  • These technologies are crucial for ensuring global food security in the face of environmental challenges.
