Yes, it's a plant parasitic nematode. That's how we're going to call it. And not only that, we can add obligate parasite. It requires a living root to survive and to reproduce. You take the nematode out of that root that it's feeding on, and it will not survive. You try to grow it on something that is not alive, you will not be able to grow it.

Yeah. Thank you for having me. My name is Horacio Lopez-Nicora. I'm the soybean pathologist and nematologist here at The Ohio State.

So, yeah, like Dylan mentioned, there's several hypotheses of how it's moving so fast because The fact that it's moving, it makes sense. We move soil around, it's going to move around. So equipment that we don't clean very well, it's going to move the nematode around. You know, it sticks to the soil and anything that can move that will move the nematode. But how did it? move so quickly, right?

How did it expand throughout North America so quickly? And a different hypothesis is that it can also travel through that digestive system of these migratory birds. These may be picking, you know, roots and particles of soil that may contain those cysts, which are the dead females that contain the eggs. And these will survive through that digestive tract, and they will be dispersed.

That's another hypothesis, right? But one thing that, you know, we were talking at the beginning is that, I mean, this is an animal, like us. It's an animal, and it penetrates the root system and overtakes the plant machinery, right?

If we go and make thin cuts from those roots where the nematode is feeding, because it feeds from particular cells that it modifies, so it turns those cells into feeding sites. And if we make very thin sections and look it under the microscopes, those cells are completely modified, resembling transfer cells. I mean, these are not cells that we are supposed to find in the root system of any plant.

They're cells that we're supposed to find in the embryo, in the seed. So the nematode is really taking control of the plant machinery and making it believe that in my root system, that's where you need to feed your progeny. I mean, of course, I'm making these extremely more simple than what it is, but we don't see symptoms.
