[Luciano Jaureguy, Doctoral Student, Department of Crop, Soil and Environmental Sciences, U of A Division of Agriculture. Luciano stands in a research lab.] My name is Luciano. We’re here at the University of Arkansas at the Plant Science building in Fayetteville. Right now, I’m working on some of my research that I do as a Ph.D. student. Basically what I’m looking for is a better seed in terms of their seed components, such as sugars and phytate. These components are very important for the quality of the seed and the uses of the soybeans. Sugars make the soybeans sweeter and also better for whatever animals feed on these soybeans. [Video shows a computer screen with a spreadsheet, an pictorial analysis with dots, and a combine harvesting soybeans.]

The phytate is the same example. It’s a component that may affect the animals’ ability to digest the soybeans. So we are looking for a soybean with a particular seed composition, which should be ideally, high sucrose, which is one of the sugars, low stachyose, which is another sugar and also, low phytate. So for that, we grow different lines of soybeans. Then we harvest the seed; we bring them to the lab and then we grind them. And then we do a chemical abstraction of these components and we determine which of all those soybeans have the particular [or the] composition that we want for our soybeans.

Here on the computer we have some pictures that I took from my assay that I performed today and as you can see, there are a bunch of dots there, different colors. But to make it simpler, [what] we’re looking at, there is different lines and we’re looking at the ones that we want, the ones that are very, very dark. Those changes or difference in colors for different lines are going to help us identify the ones with low phytate.
