Goal
You should be able to:
Discuss these topics with authority
Organize public discussions, participate in debate
Forward the scientific discussion in social media
Today is a first step.
![Page 5: Biotalknowledgey Workshop at Iowa State](https://reader030.vdocuments.us/reader030/viewer/2022032421/55a6fedc1a28abf25e8b4596/html5/thumbnails/5.jpg)
Why bother?
Negatives
You get a lot of grief.
It takes time.
Positives
It is sharing science, educating
Most people just don’t understand
The acceptance of good technology is delayed by non-scientific resistance.
![Page 6: Biotalknowledgey Workshop at Iowa State](https://reader030.vdocuments.us/reader030/viewer/2022032421/55a6fedc1a28abf25e8b4596/html5/thumbnails/6.jpg)
What happens if we do nothing?
Introduction of bad public policy
Misdirection from legitimate problems
Delaying emerging science that could benefit
Suspicion of proven successes
Mistrust of science/scientists
Reliance on less useful technology
Public labs, small co’s can’t compete
Harming non-GMO industries
![Page 7: Biotalknowledgey Workshop at Iowa State](https://reader030.vdocuments.us/reader030/viewer/2022032421/55a6fedc1a28abf25e8b4596/html5/thumbnails/7.jpg)

Central Core Concepts
Humans have always participated in plant genetic improvement.
Transgenic crop technology (familiar “GMO”) is a precise extension of conventional plant breeding.
“The techniques used pose no more risk (actually less risk) than conventional breeding.” (NAS, AAAS, AMA, EFSA many others)
In 18 years there has not been one case of illness or death related to these products
In the USA there are several traits used in only eight commercial crops (others have been deregulated, but are not currently used)
![Page 10: Biotalknowledgey Workshop at Iowa State](https://reader030.vdocuments.us/reader030/viewer/2022032421/55a6fedc1a28abf25e8b4596/html5/thumbnails/10.jpg)
It is not natural…
The first step is to defuse the appeal to nature fallacy, that is, if it is natural, it is superior to anything with human intervention.
![Page 11: Biotalknowledgey Workshop at Iowa State](https://reader030.vdocuments.us/reader030/viewer/2022032421/55a6fedc1a28abf25e8b4596/html5/thumbnails/11.jpg)

All due to mutations and genomic alterations
All required human intervention for breeding and/or selection

GM Crops Available Now
![Page 16: Biotalknowledgey Workshop at Iowa State](https://reader030.vdocuments.us/reader030/viewer/2022032421/55a6fedc1a28abf25e8b4596/html5/thumbnails/16.jpg)
Three Main Traits
Virus Resistance
Insect Resistance
Herbicide Resistance

How do we make a transgenic plant?
Get gene of interest into a single cell
Exploit the property of “Totipotency”
![Page 18: Biotalknowledgey Workshop at Iowa State](https://reader030.vdocuments.us/reader030/viewer/2022032421/55a6fedc1a28abf25e8b4596/html5/thumbnails/18.jpg)
How Do We Add a Gene to a Plant?
![Page 19: Biotalknowledgey Workshop at Iowa State](https://reader030.vdocuments.us/reader030/viewer/2022032421/55a6fedc1a28abf25e8b4596/html5/thumbnails/19.jpg)
Totipotency
Introduce the concept of plant cellular plasticity.
Cuttings, rooting
Plant cells can change identity
Some single cells can regenerate into a whole new plant, a clone.
Try that with your animal cells!
![Page 20: Biotalknowledgey Workshop at Iowa State](https://reader030.vdocuments.us/reader030/viewer/2022032421/55a6fedc1a28abf25e8b4596/html5/thumbnails/20.jpg)
Agrobacterium tumefaciens
A plant pathogen that injects its DNA into the plant upon infection. This allows the bacterium to createan environment where it can best survive.
Agrobacterium species occur naturally and areresponsible for causing “galls” in infected plants.
Scientists have exploited this property of the organism to performgene transfer in the laboratory!
New plants contain new gene constructs
![Page 21: Biotalknowledgey Workshop at Iowa State](https://reader030.vdocuments.us/reader030/viewer/2022032421/55a6fedc1a28abf25e8b4596/html5/thumbnails/21.jpg)
How Do We Make this Understandable?
Turn OFF something that normally is ON
Turn ON something that is normally OFF or not there
![Page 22: Biotalknowledgey Workshop at Iowa State](https://reader030.vdocuments.us/reader030/viewer/2022032421/55a6fedc1a28abf25e8b4596/html5/thumbnails/22.jpg)
Central Dogma of Molecular Biology
DNA – genetic material, Hard copy safe in the nucleus of a cell
RNA – Transient copy of the same information (+/-)
Protein – Does the work! Enzymes, structures, etc.
![Page 23: Biotalknowledgey Workshop at Iowa State](https://reader030.vdocuments.us/reader030/viewer/2022032421/55a6fedc1a28abf25e8b4596/html5/thumbnails/23.jpg)

Gene Silencing
GM papaya saved an industry, not a Big Ag product
Share the vision, what else could we silence? - allergens- anti-nutrients- physiology associated with post-harvest decay- many others!!

Advantages
Decrease in broad-spectrum insecticide use on corn and cotton
Lower fuel and labor costs for farmers
Solid dividends in the developing world
No effect on beneficials
Limitations
Need to plant refugia to slow resistance
Pockets of resistance are seen and require use of insecticides
Requires careful scouting

The point is– this is not a scientific debate.- benefits far outweigh limitations and new solutions are coming.
This is not a farming debate.-farmers freely choose the technology because it works.
This is a SOCIAL debate fueled by fear and misinformation.

Who is most influential in the discussion?
Oz Smith Shiva Adams Mercola Food Babe
There is money to be made in manufacturing risk.
Activists can hijack venues that appear scientific
Predatory publishing allows publication of work that lacks scientific rigor
A lot of this is anti-corporate sentiment
“They hate corporations more than they love people” – Hank Campbell, Science 2.0

Farmers Forced to Buy Seeds
Farmers do what works
Seeds are well trialed before adoption
Non-transgenic options are available
They do sign a binding agreement when buying seeds
Litigation for severe breaches, not for “a few seeds blown into field”

Agent Orange Seeds!
2,4-D is a synthetic auxin
It was used as a component of Agent Orange, one of the “rainbow herbicides”
2,4-D and 2,4,5-T were used in Agent Orange, as defoliant in SE Asia military campaigns
2,4,5-T contained co-purifying dioxin that caused health problems
Manufactured by 16 companies for the campaign

Generally:
People don’t have any idea what it is.
People don’t know how biology works.
Few understand farming and supply chains.
The just know that they don’t like biotech crops.

Communicating the Message (General)
• Communication is listening and responding• You must prove that you understand their concern• Always discuss strengths and limitations• If you don’t know, offer to find out• This is about sharing science, not beating people
to death with it.
• This is not as much a scientific exercise as a communications exercise.

• Master a central core of key concepts
• Understand mechanisms of current traits
• Know how to convey concepts to the scientifically illiterate without “dumbing it down”
• Be able to address basic mythology

Central Core Concepts
Humans have always participated in plant genetic improvement.
Transgenic crop technology (familiar “GMO”) is a precise extension of conventional plant breeding.
“The techniques used pose no more risk (actually less risk) than conventional breeding.” (NAS, AAAS, AMA, EFSA many others)
In 17 years there has not been one case of illness or death related to these products
In the USA there are several traits used in only nine commercial crops
![Page 70: Biotalknowledgey Workshop at Iowa State](https://reader030.vdocuments.us/reader030/viewer/2022032421/55a6fedc1a28abf25e8b4596/html5/thumbnails/70.jpg)
How do we fix this?
First – Dispelling the Naturalistic Fallacy
Remind audiences that genetic improvement of food is a continuum.
Very little of the food you eat comes from here.
None of the food you eat is like its “natural” form
GM technology is simply the most precise version of an age-old practice.

COMMUNICATION BARRIERS
![Page 72: Biotalknowledgey Workshop at Iowa State](https://reader030.vdocuments.us/reader030/viewer/2022032421/55a6fedc1a28abf25e8b4596/html5/thumbnails/72.jpg)
“FACTS DON’T MATTER.”- Tamar Haspel
People reject the validity of scientific conclusions if they contradict their deeply held views
“Backfire Effect”- when confronted with evidence that is contrary to their views, people tend to believe that the evidence is distorted. They also “dig in the heels” with their beliefs
Cultural Cognition – belief in trangenic harm as part of a package of beliefs
False Equivalence, “no consensus among scientists”
![Page 73: Biotalknowledgey Workshop at Iowa State](https://reader030.vdocuments.us/reader030/viewer/2022032421/55a6fedc1a28abf25e8b4596/html5/thumbnails/73.jpg)
To win hearts and minds we have to come at it from a different angle.
Humanization- I’m a parent… I care about my community… My family’s health is my priority…
Your Priorities- Profits for farmers… low environmental impacts… Food for those that need it… affordable, safe food in the industrialized world…
You can lead smart people to a conclusion- Ask questions, based on impacts for people and the environment.
![Page 74: Biotalknowledgey Workshop at Iowa State](https://reader030.vdocuments.us/reader030/viewer/2022032421/55a6fedc1a28abf25e8b4596/html5/thumbnails/74.jpg)
Your Role is to be a More Trusted Source
1. Your job- “I work for you”, “I would not be able to sleep at night knowing I did something dangerous”
2. Your funding- “all public record”, “companies sell to farmers, if they are not happy, we don’t profit”, “if anyone were to be harmed we’d be out of business”
3. If you have connections to ag companies, talk about them.
4. Know the role of your institution in sponsorship, etc.
Transparency builds trust, trust helps communication.

Avoid these Mistakes
Avoid “feed the world” rhetoric
Discuss strengths and limitations
Not a panacea, not a disaster
Never get backed into the “science no”
“Can you guarantee that these are absolutely safe?”
![Page 76: Biotalknowledgey Workshop at Iowa State](https://reader030.vdocuments.us/reader030/viewer/2022032421/55a6fedc1a28abf25e8b4596/html5/thumbnails/76.jpg)
Rely on Graphics Over Words
Instead of “glyphosate is relatively harmless- don’t worry about it.”

Strawberries requiring less fungicide
Strawberries are the most fungicide-intensive crop
Overexpression of the NPR1 gene allows them to grow in presence of high fungal pressure.
Plants overexpressing NPR1 were inoculated with a series of pathogens and moved to warm, humid conditions.

Conclusions:
The pipeline started with farm-centric products
Few horticultural crops are commercialized due to cost and high barriers in deregulation.
The future products emphasize traits with direct consumer benefit
Emphasizing benefits for consumers, the environment, the developing world and the farmer helps to change hearts and minds.
Other countries will independently pursue the technology.

In Conclusion
Our mission is to develop genetics and production methods to generate more food on the same space with fewer inputs.
Learn the basics, or at least learn where to find the basics
When communicating these topics, remember, DON’T BE SUCH A SCIENTIST. Facts don’t matter. You need to be a trusted conduit first, before information can be persuasive.
