Plant Biotechnology

What is plant biotechnology?

• Manipulating plants and plant parts for

practical uses

– Improved food crops

• Higher yields

• Improved nutrition

• Environmental tolerances

– Improved production of valuable molecules

– Production of novel molecules

Biotechnology and modern agriculture

A brief history of crop

improvement

• Strategies to manipulate genomes

– Selection of desirable traits (manipulating population

genetics)

– Introducing new genetic traits to a genome

  • Hybridization technologies
    • Cross pollination
    • Plant tissue culture (protoplast fusion)
  • Gene transfer technologies
    • Genetic “transformation” (gene gun, Agrobacterium

tumefaciens )

– Create a new trait (directed evolution)

Crop domestication

  • Artificial selection since ~9,000 B.C.

Selection of desirable genetic traits

Many

selection

strategies have

been

developed

  • Example: Mass selection
