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.
Transgenic Plants02:50

Transgenic Plants

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...
Gene Flow02:39

Gene Flow

Gene flow is the transfer of genes among populations, resulting from either the dispersal of gametes or from the migration of individuals.
Incomplete Dominance01:43

Incomplete Dominance

Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.

Background and Environment Affect Phenotype

Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

Summary

Genetic data reveal crop origins, domestication events, and molecular changes. These findings align with archaeological evidence, portraying domestication as a gradual, widespread process.

Area of Science:

  • Evolutionary biology
  • Genetics
  • Archaeology

Background:

  • Crop domestication is a complex process studied by biologists and anthropologists.
  • Genetic data offer insights into crop origins, domestication events, and artificial selection.
  • Recent archaeological findings suggest domestication was gradual and geographically diffuse.

Purpose of the Study:

  • To review genetic methodologies used in crop evolution research.
  • To highlight recent genetic insights into crop domestication timing and patterns.
  • To discuss the genetic basis of domestication, diversification, and improvement traits.

Main Methods:

  • Quantitative trait locus (QTL) mapping
  • DNA resequencing
  • Analysis of genetic data in conjunction with archaeological evidence.

Main Results:

  • Genetic inferences are compatible with archaeological data on gradual domestication.
  • Identified methodologies for analyzing genetic data in crop evolution.
  • Highlighted insights into the timing, spatial patterns, and genetic underpinnings of crop domestication.

Conclusions:

  • Genetic and archaeological data collectively support a gradual, geographically diffuse model of crop domestication.
  • Advances in genetic analysis provide powerful tools for understanding crop evolution.
  • Distinct genetic mechanisms underlie domestication, diversification, and crop improvement.
