Abstract Background Poplar Populus sp. has emerged as the main model system for molecular and genetic studies of forest trees. A Populus expressed sequence tag EST database POPULUSDB was previously created from 19 cDNA libraries each originating from different Populus tree tissues and opened to the public in September 2004. We used this dataset for in silico transcript profiling of a particular process in the woody tissues of the Populus stem the programmed death of xylem fibers. Results One EST library in POPULUSDB originates from woody tissues of the Populus stem where xylem fibers undergo cell death. Analysis of EST abundances and library distribution within the POPULUSDB revealed a large number of previously uncharacterized transcripts that were unique in this library and possibly .
