The Latest Biotech News

ND GMO Planting Decisions (Winter 2005)

  • New law enacted during 2005 legislative session

  • Only the ND state government has the authority to ban

  • plantings of GMO crops

  • Response to laws passed at county level in other states

EU Approving GMO-free Zones (May 2005)

  • European Union GMO regulations permit regions

  • to declare themselves GMO

  • Otherwise approved GMO products can be grown

  • 162 regions or provinces (=US states) have asked to be

  • GMO free

  • 4500 total government units have made the request

What is Biotechnology?

How about some definitions

General Definition

The application of technology to improve

a biological organism

Detailed Definition

The application of the technology to modify

the biological function of an organism

by adding genes from another organisms

What is biotechnology

What is the Result of Biotechnology?

  • An organism showing a novel trait not normally found in the species

Extended shelf-life tomato

(FlavrSavr Tomato)

Herbicide resistant soybean

(Roundup Ready Soybean)

What is biotechnology

Biotechnology Terms You Probably Heard

Transgene – the foreign gene added to a species

Ex. – modified EPSP synthase gene (encodes a protein that

functions even when plant treated with Roundup)

Transgenic – an organism containing a transgene introduced by technological (not breeding) methods

Ex. – Roundup Ready Crops

What is biotechnology

Biotechnology Develops

GMOs - Genetically modified organisms

  • GMO - an organism that expresses traits that result

  • from the introduction of foreign DNA

  • Also called transgenic organism

What is biotechnology

Important Terms

  • Breeding

  • Beneficial gene added from the same species

  • Gene delivered by mating within the species

Source: USDA

  • Transformation

  • Beneficial gene added from another species

  • Gene delivered by plant genetic engineering

Source: USDA

What is biotechnology

Let’s Be Up Front

  • Breeding  Biotechnology

    •  Breeding only exchanges genes found in the species

    • Breeding can transfer the transgene to other breeding materials

    • BUT it is not the same as biotechnology

  • Biotechnology adds traits not available in the species

    •  Soybean does not have a gene to breakdown Roundup

    • The gene comes from bacteria

What is biotechnology

Interspecific Cross





New species, but

NOT biotechnology


What is biotechnology

Mutagenesis: New Trait, No Foreign Gene

  • Mutagenesis changes the sequence of a gene

  • New, useful traits can be obtained











What is biotechnology

BASF Clearfield Products

Mutagenesis Crops

  • Herbicide resistance

    • imidazolinones

  • Mutant AHAS enzyme

    • developed by mutagenesis

  • Crops

    • Canola, Corn, Rice, Sunflower, Wheat

  • In US

    • Not considered GMOs by USDA regulators

    • A Major marketing advantage

    • When some stacked with GMOs, the advantage lost

Edible Vaccines – A Biopharming Dream

Biotech Plants Serving Human Health Needs

  • A pathogen protein gene is cloned

  • Gene is inserted into the DNA of plant (potato, banana, tomato)

  • Humans eat the plant

  • The body produces antibodies against pathogen protein

  • Human are “immunized” against the pathogen

  • Examples:

    • Diarrhea

    • Hepatitis B

    • Measles

Nutritional Genomics

(Nutrigenomics: a coming

Biotechnology innovation)

  • Concepts of Nutrigenomics

  • Certain diets can cause severe health risks in individuals

    • Refined sugars, dairy products, fatty foods

  • Certain diets enhance disease susceptibility in individual’s

  • with a specific genetic makeup

    • Diabetes, lactose intolerance, high cholesterol

  • Diets based on an individuals genetic makeup are preferred

    • No refined sugars, minimal dairy products

    • or fatty foods

What is biotechnology

Nutritional Genomics
