Plant Breeding and Biotechnology

19.9K
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

7.5K
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...

Genome editing technologies allow scientists to modify an organism’s DNA via the addition, removal, or rearrangement of genetic material at specific genomic locations. These types of techniques could potentially be used to cure genetic disorders such as hemophilia and sickle cell anemia. One popular and widely used DNA-editing research tool that could lead to safe and effective cures for genetic disorders is the CRISPR-Cas9 system. CRISPR-Cas9 stands for Clustered Regularly Interspaced...

Area of Science:

  • Agricultural Science
  • Biotechnology
  • Genetics

Background:

  • Genome editing technologies, including CRISPR/Cas9 and TALEN, are advanced genetic modification tools applicable to basic science and crop breeding.
  • Nutritional enhancement in crops is a key objective, pursued through conventional breeding and genetic modification.

Purpose of the Study:

  • To review nutritional traits in crops suitable for genome editing.
  • To discuss the effectiveness of genome editing technology in improving crop nutritional traits.

Main Methods:

  • Review of current literature on genome editing applications in crop nutritional improvement.
  • Analysis of specific examples like high GABA tomatoes and high oleic acid soybeans.

Main Results:

  • Genome editing allows for mutations nearly identical to spontaneous ones, facilitating market entry for edited crops.
  • The primary application of genome editing currently focuses on gene disruption rather than gene delivery.
  • Genome editing offers a distinct approach compared to traditional genetic recombination for trait development.

Conclusions:

  • Genome editing is a potent breeding technology for enhancing nutritional traits in crops.
  • The distinct nature of genome editing may necessitate different strategies compared to conventional genetic recombination.
  • Market accessibility for genome-edited crops is anticipated to be more straightforward than for GMOs.
