4D Analysis of Molecules by Aptamers in Soil (4DMAPS)

The field of botany is well over a thousand years old, and the practice of agriculture millennia older than that. Yet surprisingly, little is understood about how plant roots interact with soil at the molecular level, a narrow zone around roots of intense microbial activity that scientists call the rhizosphere.

That zone of microbial activity could hold information valuable to understanding how plants stimulate microbes to transform nutrients and promote plant health, resist disease, and adapt to environmental changes and stress. 

To better understand the rhizosphere, Ames Laboratory is leading an endeavor to develop a model instrument that will enable scientists to look at the biological interactions in the rhizosphere in real time, in the field. 

This research is supported by the U.S. Department of Energy, Office of Science, Biological and Environmental Research (BER) through the Ames Laboratory. The Ames Laboratory is operated for the U.S. Department of Energy by Iowa State University under Contract No. DE-AC02-07CH11358.
