Research Project: MICROARRAY DESIGN AND PREPARATION FOR UNIVERSAL PLANT VIRUS MICROARRAY Project Number: 1230-22000-032-05
Project Type: General Cooperative Agreement

Start Date: Jun 01, 2009
End Date: Dec 31, 2012

Objective:
To develop and validate a universal plant virus microarray for detection and differentiation of plant viruses. To demonstrate the ability of an oligonucleotide microarray to detect and differentiate plant viruses from random amplification of plant total nucleic acid extracts.

Approach:
ARS and the Cooperator will assemble the lists of viral taxa to be represented on the viral detection microarray, and virus-infected samples from which to amplify nucleic acids to validate the microarray. This information and material will be utilized by both ARS and the Cooperator to jointly develop and validate the microarray for detection of target viruses, and to make validation results available to collaborators via a web server. The Cooperator will perform analysis of viral sequences to identify suitable sequences for the development of oligonucleotides, supervise production of the microarrays based on the selected oligonucleotides, perform assays to validate the array with as many viruses as possible from the collections of all cooperators, and participate in analysis of microarray hybridization results to determine with a high degree of confidence which viruses were present in validation samples.
