Sessions Sponsored by the
Forest Pathology Committee at the
2013 APS Annual Meeting
The 2013 APS meeting was held August 11-14, in Austin, Texas.
In addition to the field trip and special sessions there were also forest pathology papers sprinkled throughout the technical sessions, and forest pathology posters in the poster session.
Field Trip: Current Perspectives on Abiotic and Biotic Threats to Forest and Shade Trees of Texas
9:00 a.m. - 4:00 p.m.
Organizers: Matthew Kasson, Virginia Tech, Blacksburg, VA, U.S.A.; Isabel Munck, USDA Forest Service, Durham, NH, U.S.A.; Jim Houser, Texas Forest Service, Austin, TX, U.S.A.
Sponsoring Committee/Sponsor: Forest Pathology
The field trip will emphasize current abiotic and biotic threats, including oak wilt, Hypoxylon canker, leaf scorch, fire, and drought, to Texas forest and shade trees. Participants will visit several locations, including the Bastrop State Park, which was devastated by wildfires in 2011. Attendees will interact with local forest health specialists and pathologists to discuss research, surveys, and long-term drought and fire and their impact on forest health planning.
Committee Meeting: Saturday August 10th, 6:30-8:00 p.m.
(none sponsored by Forest Pathology, but these are topically related)
Functional, Evolutionary, and Ecological Diversity of Wood Decay Systems
Sunday, August 11
1:00 - 4:00 p.m.
Organizer: David Hibbett, Clark University, Worcester, MA, U.S.A.
Section: Ecology and Epidemiology
Sponsoring Committee/Sponsor: Mycology
Wood decay has profound biogeochemical consequences, impacts timber-based industries, and has potential applications in biofuels. Wood decayers have been divided into two categories: white rot and brown rot, but genomics has revealed diversity within each class, and ecologists have long shown substrate and habitat preferences of particular species. This session highlights the diversity of wood decay systems from the perspectives of genomics, biochemistry, evolutionary biology, and ecology.
- Mechanisms of wood decay inferred from recent genome investigations. D. CULLEN, USDA Forest Products Laboratory, Madison, WI, U.S.A.
- Time-dependent expression of genes encoded by Phanerochaete carnosa during growth on heartwood from deciduous and coniferous wood. E. MASTER, University of Toronto, Toronto, ON, Canada
- Wood decay in the Ozark Highlands: Variation across species, space, and time. A. ZANNE, George Washington University, Washington, DC, U.S.A.
- Wood-rotting fungi have a dark history: Evidence from the fossil record. C. HARPER, University of Kansas, Lawrence, KS, U.S.A.
- Wood decay in extreme environments. R. BLANCHETTE, University of Minnesota, St. Paul, MN, U.S.A.
- Novel industrial lignocellulose-degrading enzymes. A. BERLIN, Novozymes, Inc., Davis, CA, U.S.A.
- Diversification of wood decay systems in early evolution of Agaricomycotina. L. NAGY, Clark University, Worcester, MA, U.S.A.
Invasive Threats to Palm Trees
Tuesday, August 13
8:30 - 11:30 a.m.
Organizers: Richard Lee, USDA ARS NCGRCD, Riverside, CA, U.S.A.; Carlos Angel, University of Missouri, Columbia, MO, U.S.A.
Section: Diseases of Plants
Sponsoring Committees/Sponsors: Tropical Plant Pathology; Diseases of Ornamental Plants; Vector-Pathogen Complexes
Palms used for ornamental and food production in the United States are under increasing threats to invasive pathogens and pests. The purpose of this session is to educate and inform commodity stakeholders, regulatory personnel, nurseries, and interested scientists of the nature of the threats.
- Molecular characterization of lethal yellows and other phytoplasmas. B. BEXTINE, University of Texas-Tyler, Tyler, TX, U.S.A.
- Texas Phoenix palm decline and potential vectors. S. HALBERT, Florida Division of Plant Industry, Gainesville, FL, U.S.A.
- Cadang-cadang disease of palm and other diseases. R. LEE, USDA ARS NCGRCD, Riverside, CA, U.S.A.
- Diagnosis of palm declines in the National Plant Disease Diagnostic Network. K. ONG, Texas A&M University, College Station, TX, U.S.A.
- Palm diseases in Central America. M. MERCEDES ROCA, Zamorano University, Tegucigalpa, Honduras
