A few years ago, a team of engineers at the University of Arizona was working on a gene-editing technique called CRISPR.
CRISBRases are proteins that can be inserted into a DNA sequence and modified to attack specific genes in the DNA of a target organism.
One of the researchers, Matthew Fazio, had worked with a company called BioRad, which specializes in modifying genes to make them more difficult to target.
His group was able to get a gene to turn off a protein that had been turned on by a virus that infected bacteria.
The CRISDRases were already pretty useful in helping to make plants grow faster.
The problem was, the engineered plants didn’t have any resistance to the virus.
“It was like trying to kill a mosquito with a dart,” Fazie said.
They had to be careful to make sure that they didn’t over-target a gene.
So, Fazies team made another modification to the CRISP gene to make it resistant to the newly-discovered virus.
The result was a strain that could withstand the strain of the bacteria they were working with.
The strain was engineered to have a protein called PEGAGAGAGGAGGACATATACAGAAGGTTTTTTT that had already been turned off by the virus, so the engineered plant had no effect on it.
It’s a pretty good result, but the next step was to find out whether that would work against other varieties of bacteria.
So Fazios team put another strain on a plant they were studying and bred it against other plants.
Then they put it in the same environment where the virus was being expressed, but with the CRIST variants removed.
The modified plant had the same ability as the original plant to fend off the virus as the new strain.
But the modified plant didn’t respond as well as the other plants when it came to the viral attack.
They found that the modified plants were more resistant to a viral strain that the original strain had evolved from.
It turned out that the CRist variant was not only more resistant but also had a protein gene that was less likely to be turned off when the virus is present.
So if you are looking for something that can kill viruses, this is the strain that you should look for.
But what about the other varieties?
What if you don’t want to breed them with your modified plants?
What about those strains that are resistant to viruses but also have a few other things going for them?
“What we were really interested in was the fact that if you can’t kill a virus, then it’s probably not going to do much harm,” Fazzi said.
And so the next time you want to use a modified plant, just replace it with one that is resistant to whatever virus you are working with—even though the original ones are not.
So, it turns out that a lot of engineered plants are really not very useful, Fazzies team concluded. “
If we can get rid of the CRISM, then you can go and use it in any other situation where you would like to use the engineered version.”
So, it turns out that a lot of engineered plants are really not very useful, Fazzies team concluded.
If you want a plant to work well, the only way to get rid in a situation where the engineered one can’t be used is to use it with another plant that has the same CRIST variant.
And if that is not possible, then the engineered variant will be used instead.
Faziams group is just one of many groups working to engineer plant DNA so that it can be used for more than just killing viruses.
There are a number of other projects that are working on similar techniques, including the work of the Harvard group that discovered a gene that is critical for the growth of some plants.
The Harvard group is now working on another gene that has been shown to be critical for plant growth and resistance to disease, and a gene called BRCA1 that plays a key role in breast cancer.
“This is not a new thing.
We have been finding these gene variants in all sorts of organisms,” said Fazzian, “so it’s very hard to see why this one was overlooked.”
Fazian said that it’s important to not be complacent about the possibilities.
“I would just say to people who are going to use engineered plant DNA, do not use it if it’s going to cause a problem,” he said.
The scientists said that they will continue to find new genes that could be modified to help plants become resistant to various viruses, and that some genes are already doing this work.
The next big challenge, according to Fazziones team, will be figuring out how to work with plants that are genetically engineered to do something that other plant DNA is not capable of doing.
“At this point, we know how to
