in Forest Trees
July 31 to August 5, 2011 – Eugene, Oregon, USA
The Forest Service of the U.S. Department of Agriculture is dedicated to the principle of multiple use management of the
Nation’s forest resources for sustained yields of wood, water, forage, wildlife, and recreation. Through forestry research,
cooperation with the States and private forest owners, and management of the national forests and national grasslands, it
strives—as directed by Congress—to provide increasingly greater service to a growing Nation.
The U.S. Department of Agriculture (USDA) prohibits discrimination in all its programs and activities on the basis of race,
color, national origin, sex, religion, age, disability, sexual orientation, marital status, family status, status as a parent (in
education and training programs and activities), because all or part of an individual’s income is derived from any public
assistance program, or retaliation. (Not all prohibited bases apply to all programs or activities).
If you require this information in alternative format (Braille, large print, audiotape, etc.), contact the USDA’s TARGET Center
at (202) 720-2600 (Voice or TDD).
If you require information about this program, activity, or facility in a language other than English, contact the agency office
responsible for the program or activity, or any USDA office.
To file a complaint alleging discrimination, write USDA, Director, Office of Civil Rights, 1400 Independence Avenue,
S.W., Washington, D.C. 20250-9410, or call toll free, (866) 632-9992 (Voice). TDD users can contact USDA through
local relay or the Federal relay at (800) 877-8339 (TDD) or (866) 377-8642 (relay voice users). You may use USDA
Program Discrimination Complaint Forms AD-3027 or AD-3027s (Spanish) which can be found at:

Abstract
Sniezko, R.A.; Yanchuk, A.D.; Kliejunas, J.T.; Palmieri, K.M.; Alexander, J.M.; Frankel, S.J. 2012.
Proceedings of the Fourth International Workshop on the Genetics of Host-Parasite Interactions in
Forestry: Disease and Insect Resistance in Forest Trees. General Technical Report PSW-GTR-240.
Albany, CA: U.S. Department of Agriculture, Forest Service, Pacific Southwest Research Station. 372 p.
The Fourth International Workshop on the Genetics of Host-Parasite Interactions in Forestry: Disease and
Insect Resistance in Forest Trees provided a forum for research and management options and successes
which have occurred over the last 30 years (the previous workshop was held in 1980 in Wageningen, The
Netherlands). Eighty-eight submissions from oral and poster presentations at the 2011 workshop held in
Eugene, Oregon provide a worldwide, comprehensive update on many aspects of research and operational
programs on genetic resistance to forest insects and diseases. Topics of concern to natural forest systems
and intensively managed forests are discussed, including resistance mechanisms, durability of resistance,
ecology and evolutionary biology of resistance and tolerance, pathogen evolution, molecular tools, shortterm screening assays for resistance and status of several applied forest tree resistance programs.
Key words: forest disease and insect resistance, evolutionary biology, climate change, durable resistance
