Globodera pallida, one of the two species of potato cyst nematode (PCN), has been found in nine fields in the eastern part of the state of Idaho. The discovery of this devastating potato pest poses threat to the potato industry of the U.S. Understanding the genetic complexity of field populations of this emerging nematode species and developing novel control tools are necessary to aid the eradication of G. pallida in Idaho. We will use the chorismate mutase gene as a genetic marker to evaluate genetic variations among G. pallida field populations; and, we will develop novel nematode resistance in potato through a plant-delivered RNAi technology.
