Plant Breeding and Biotechnology

19.7K
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.

In-vitro Mutagenesis

14.2K
To learn more about the function of a gene, researchers can observe what happens when the gene is inactivated or “knocked out,” by creating genetically engineered knockout animals. Knockout mice have been particularly useful as models for human diseases such as cancer, Parkinson’s disease, and diabetes.

Transgenic Plants

7.4K
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...

Mutation, Gene Flow, and Genetic Drift01:09

Mutation, Gene Flow, and Genetic Drift

59.3K
In a population that is not at Hardy-Weinberg equilibrium, the frequency of alleles changes over time. Therefore, any deviations from the five conditions of Hardy-Weinberg equilibrium can alter the genetic variation of a given population. Conditions that change the genetic variability of a population include mutations, natural selection, non-random mating, gene flow, and genetic drift (small population size).

Area of Science:

  • Forestry Science
  • Plant Biotechnology
  • Conservation Biology

Background:

  • Tree breeding and genetic engineering are often viewed as competing disciplines.
  • Each field has historically criticized the other's practicality and cost-effectiveness.

Purpose of the Study:

  • To demonstrate the synergistic potential of tree breeding and genetic engineering in forestry.
  • To outline the purposes of genetic engineering in forest tree improvement.
  • To emphasize the integration of genetic engineering with traditional tree breeding.

Main Methods:

  • Developing a generalized approach for integrating genetic engineering and tree breeding programs.
  • Evaluating tree engineering initiatives within the context of silviculture and tree improvement.
  • Utilizing a case study of the American chestnut (Castanea dentata) for illustration.

Main Results:

  • Both tree breeding and genetic engineering offer significant contributions to forestry.
  • Successful implementation requires integrating genetic engineering from the outset of tree improvement programs.
  • The case study highlights the value of combined approaches for conservation.

Conclusions:

  • Genetic engineering and tree breeding are complementary, not antagonistic, in advancing forestry.
  • A holistic approach integrating both disciplines is essential for effective tree improvement.
  • The successful conservation of species like the American chestnut relies on this integrated strategy.
