Plant Breeding and Biotechnology

22.0K
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

8.9K
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...

CRISPR/Cas9 Genome Editing

2.2K
The CRISPR-Cas system serves as a bacterial defense mechanism against invading genetic elements such as viruses and plasmids, forming the foundation for its adaptation as a powerful genome-editing tool. Originally discovered in prokaryotes, this system has been repurposed to revolutionize genetic engineering across a wide range of organisms, including plants, animals, and humans. The core component, Cas9, is an endonuclease derived from Streptococcus pyogenes, capable of introducing...

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:

  • Plant Science
  • Genetics
  • Molecular Biology

Background:

  • Genome editing technology (GET) offers versatile genotype and phenotype alteration.
  • Conventional methods lack efficiency and site-specificity for mutagenesis.
  • Artificial nucleases represent a new frontier in genome modification.

Purpose of the Study:

  • To review the development of various genome editing technologies.
  • To highlight applications of GET in plants.
  • To discuss different cleavage systems and their mechanisms.

Main Methods:

  • Categorization of GETs into protein-dependent (ZFN, TALEN), RNA-dependent DNA (CRISPR-Cas9, CRISPR-Cpf1, CRISPR-C2c1), and RNA-dependent RNA (RNAi, CRISPR-C2c2) cleavage systems.
  • Explanation of DNA break mechanisms (DSB, SSB) and repair pathways (NHEJ, HR).
  • Discussion of induced mutations: gene knock-out, knock-in, and replacement.

Main Results:

  • GETs facilitate targeted mutagenesis for trait modification.
  • Applications include enhancing plant resistance and improving physiological mechanisms.
  • GETs can modify plant morphology and growth.

Conclusions:

  • Site-directed mutagenesis via GETs is crucial for plant improvement.
  • Advanced GETs offer enhanced efficiency and specificity.
  • This review provides a non-comprehensive overview of GET development in plants.
