The GeneChip® Poplar Genome Array is designed specifically to monitor gene expression in Poplar (Populus sp.). In total, the Poplar Genome Array contains more than 61,000 probe sets representing over 56,000 transcripts and gene predictions.

This array was created in collaboration with leading poplar researchers through the Affymetrix GeneChip® Consortia Program and was designed based on content from UniGene Build #6 (March 16, 2005) and from GenBank® mRNAs and ESTs for all Populus species up to April 26, 2005. Additional array design content was derived from the predicted gene set v1.1 from the Populus genome project (P. trichocarpa), led by the U.S. Department of Energy and based at the Joint Genome Institute (JGI), Walnut Creek, CA (download date May 4, 2005).
