Research Project: MOLECULAR CHARACTERIZATION OF FIELD POPULATIONS OF GLOBODERA PALLIDA FROM IDAHO AND DEVELOPMENT OF NOVEL NEMATODE RESISTANCE IN POTATO

Location: Biological Integrated Pest Management Unit

Project Number: 1907-22000-021-13
Project Type: Reimbursable

Start Date: Sep 01, 2010
End Date: Aug 30, 2013

Objective:
To understand the genetic complexity of field populations of the emerging species of potato cyst nematode (PCN) and to develop novel control tools to aid the eradication of PCN in Idaho. Specific objectives include: 1. Use the chorismate mutase gene as a genetic marker to evaluate genetic variations among G. pallida field populations. 2. Develop novel nematode resistance in potato through a plant-delivered RNAi technology.

Approach:
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.
