Transgenic Plants

8.8K
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...

Bacterial Transformation

In 1928, bacteriologist Frederick Griffith worked on a vaccine for pneumonia, which is caused by Streptococcus pneumoniae bacteria. Griffith studied two pneumonia strains in mice: one pathogenic and one non-pathogenic. Only the pathogenic strain killed host mice.
Griffith made an unexpected discovery when he killed the pathogenic strain and mixed its remains with the live, non-pathogenic strain. Not only did the mixture kill host mice, but it also contained living pathogenic bacteria that...

Area of Science:

  • Plant Science
  • Biotechnology
  • Genetics

Background:

  • Efficient genetic transformation is crucial for crop improvement in cereals.
  • Existing methods often lack genotype flexibility and efficiency, hindering progress.

Purpose of the Study:

  • To develop a simple, efficient, and genotype-flexible method for cereal transformation.
  • To demonstrate the broad applicability of the new method across diverse cereal species and genotypes.

Main Methods:

  • The In-planta Agrobacterium-mediated cereal transformation (InPACT) method was developed.
  • InPACT was tested on 32 wheat genotypes (29 hexaploid, 3 tetraploid), along with barley, oat, and rice germplasm.

Main Results:

  • Successful transformation was achieved across 32 wheat genotypes, showcasing significant genotype flexibility.
  • The InPACT method proved highly reproducible, with both experienced users and learners achieving successful transgenic wheat generation.
  • The method's utility was confirmed in other cereal crops, including barley, oat, and rice.

Conclusions:

  • InPACT offers a robust and versatile platform for genetic engineering in small grain cereals.
  • This method has the potential to accelerate crop breeding and research in wheat, barley, oats, and rice.
