Transgenic Plants

7.0K
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...

Plant Breeding and Biotechnology

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.

Trihybrid Crosses
Some of Mendel’s crosses examined three pairs of contrasting characteristics. Such a cross is called a trihybrid cross. A trihybrid cross is a combination of three individual monohybrid crosses. For example, plant height (tall vs. short), seed shape (round vs. wrinkled), and seed color (yellow vs. green).
The F1 generation plants of a trihybrid cross are heterozygous for all three traits and produce eight gametes. Upon self-fertilization, these gametes have an equal...

Summary

Researchers developed a method for genetically engineering indica rice (Oryza sativa). This system successfully produced transgenic rice plants expressing introduced genes, demonstrating stable inheritance in offspring.

Area of Science:

  • Plant Biotechnology
  • Genetics
  • Molecular Biology

Background:

  • Genetic engineering of indica rice varieties is crucial for crop improvement.
  • Efficient methods for producing transgenic indica rice are needed.

Purpose of the Study:

  • To establish a reliable system for genetically engineering indica rice var 'IR54'.
  • To verify gene integration, expression, and inheritance in the resulting transgenic plants.

Main Methods:

  • Protoplast isolation from indica rice suspension cells.
  • Gene introduction using polyethylene glycol (PEG) mediated transformation.
  • Selection of transformed cells using G-418 resistance.
  • Regeneration of transgenic plants and molecular analysis (Southern blot).

Main Results:

  • Transgenic indica rice plants were successfully regenerated using G-418 selection.
  • Southern blot analysis confirmed the integration of neo and gusA genes.
  • The CaMV35S promoter drove gusA gene expression in all examined organs.
  • Mendelian inheritance of the gusA gene was observed in progeny.

Conclusions:

  • A robust system for genetic engineering of indica rice var 'IR54' has been established.
  • The developed method allows for the production of fertile transgenic rice with stable gene expression and inheritance.
