By David McNew, AP Science writerToward the end of last year, the sunflowers started to look very sick.
It was the time of the annual migration of white-tailed deer, a major pest in the area.
It wasn’t a new problem.
In 2014, the last year for which data was available, nearly a quarter of white tail deer killed in the state of Oregon had been infected with the white-tail deer parasite.
By last spring, the number had soared.
Now, the disease had taken a big toll on the sunfruits.
In August, a new strain of whitetail deer was found in the wild in western Washington.
It had also spread to the sun fruit.
Sunflowers, by contrast, are relatively benign.
They’re part of a crop of crops that can’t be pollinated, unlike the fruit of the winter squash or potato.
The flowers produce pollen that is eaten by insects and then washed out of the plant.
They are not pollinated.
They aren’t an edible plant.
So, the question is, how do you get the pollen out of them?
That’s what scientists at the University of Washington and the National Center for Environmental Health Sciences at the Centers for Disease Control and Prevention (CDC) decided to look.
The team looked at what the researchers call “exogenous” pollen, which is made up of naturally occurring pollen from insects and plants.
Exogenous pollen comes from the pollen of plants that have been parasitized by other species, and is produced when the pollen is eaten.
This is because the plant itself is the carrier of the virus that causes the whitetail infection.
“If we can do something that is so important to us as a species, why can’t we do it?” says Dr. Michael T. Trowbridge, a professor of plant pathology at UW.
Trowbridge and his colleagues were able to identify what happened in the sunfruit plant when it was infected with white-tails.
They found that the pollen produced by the plants was not the same as that produced by other sunflower plants.
So they found that some of the pollen was made up from a virus that was different from the virus found in sunflowered plants.
This virus was a different strain than the one that had been found in whitetail disease in the spring of 2014.
Trowsbridge’s team found that this virus was not present in all of the sun fruits they examined.
And they found a virus in the pollen that was not found in any other plant.
The findings of this study were published in the journal PLOS ONE.
They suggest that the white tail virus may have emerged from natural pollen from other plants.
And if it did, then that could be one way to make it easier for people to find sunflax seeds that they could harvest.
The researchers are now working on developing more of these tests to be able to find the different strains of the whitetails and to see whether they are genetically different.
“This is a new way to look at this disease,” Trowsbridles says.
“We’ve just scratched the surface of what we know.”
The researchers say that they have now identified a strain of the disease that was present in the seeds and pollen of the entire sunflower crop, which accounts for about 10 percent of all the sun’s food.
They also identified the genetic variant that causes whitetails.
And when they look at a different variant in the genetic code of other sunfarms, they find that they can’t see a genetic difference in the virus in any of the different varieties.
So the researchers are trying to figure out how they came to the conclusion that the virus was present even in all the different sunfarming varieties, and that it was the same virus found to be present in sunfarmed plants.
It’s not clear how much white-tails are causing the epidemic, but if the virus is spreading to the whole crop, it could be very bad news for farmers, since it would mean that many sunflops would not be able be harvested this year, Trowsbrey says.
“The disease is spreading rapidly in this state, and the only way we can control it is to eradicate the whitetrees,” he says.
The scientists have been working with growers in the region, who are struggling to control the disease, and are hoping to find ways to protect the crops, he says, but it will take time to figure that out.
Trees are important to our economy, and there are a lot of things we need to do to protect our forests, he adds.
It could be years before we know whether whitetails are the cause of the outbreak, Trowbridles adds.
But it would be very interesting to see what happens when we find out, because we can start to control whitetails before it’s too late.
