2007 Annual Report
1931-21000-016-03R - Reimbursable Cooperative Agreement with The Pennsylvania State University, Cornell University, and the USDA-CSREES National Research Initiative (NRI). ESTs associated with fire blight infection were identified. Project is monitored through monthly conference calls among the project members. For a complete report on the progress of this agreement, see the report for 1931-21000-016-03R.
1931-21000-016-04G - Assistance-type Cooperative Agreement with the Pennsylvania State University. Genes associated with fire blight infection were identified. Progress is monitored through monthly conference calls among the project members. For a complete report on the progress of this agreement, see the report for 1931-21000-016-04G.
1931-21000-016-05G - Assistance-type Cooperative Agreement with Cornell University. Gene expression of fire blight resistant and susceptible cultivars was measured. Progress is monitored through monthly conference calls among the project members. For a complete report on the progress of this agreement, see the report for 1931-21000-016-05G.
1931-21000-016-06S - Specific Cooperative Agreeement with the University of Illinois. The objective of this agreement is to produce a 40,000 gene apple microarray to be used for functional genomic studies in the Rosaceae. Progress: The first printing of the microarray was completed in July, 2007. The quality of the array is currently being assessed by both parties. Progess is monitored through bi-weekly to monthly phone conferences to deal with critical questions regarding the design, printing, and quality analysis of the microarray. For a complete report on the progress of this agreement, see the report for 1931-21000-016-06S.

TITLE: Identification of Genes Associated with Apple’s Response to Fire Blight Disease. PROBLEM: Fire blight is a destructive disease of apple and pear trees that is estimated to cost the U.S. fruit industry over $100 million a year in crop losses and disease control. ACCOMPLISHMENT: A technique known as 'suppression subtractive cDNA hybridization' was used to identify genes in apple that respond to fire blight infection. A total of 468 apple genes were identified that responded to the disease between 1 and 72 hours after challenge with the fire blight pathogen. The DNA sequence of these genes was deposited in a publicly accessible database maintained by the National Center for Biotechnology Information (http://www.ncbi.nlm.nih.gov). IMPACT: This genetic information will be used by biologists, horticulturalists, and plant breeders to develop new strategies for improving plant resistance to fire blight disease. NATIONAL PROGRAM COMPONENT 2: Plant Molecular and Biological Processes. NATIONAL PROGRAM PROBLEM STATEMENT 2B: Plant Interactions with their Environment.
