Analysis of 4,664 high-quality sequence-finished poplar full-length cDNA clones and their utility for the discovery of genes responding to insect feeding

Table 1 Libraries, tissue sources and species for sequences described in this study

cDNA Library	Tissue/Developmental Stage	Species (genotype)
PT-X-FL-A-1	Outer xylem^a.	Populus trichocarpa (Nisqually-1)
PT-P-FL-A-2	Phloem and cambium^a.	P. trichocarpa (Nisqually-1)
PT-GT-FL-A-3	Young and mature leaves, along with green shoot tips^a.	P. trichocarpa (Nisqually-1)
PTxD-IL-FL-A-4	Local and systemic (above region of feeding) mature leaves harvested after continuous feeding by forest tent caterpillars, Malacosoma disstria. Local tissue was collected 4, 8 and 24 h post-treatment and systemic tissue 4, 12 and 48 h post-treatment^b.	P. trichocarpa × deltoides (H11–11)

^aHarvested May 15th, 2001 from eight year old trees within the Boise Cascade region of Washington state.
^bOne or two year old saplings grown in potted soil under greenhouse conditions at the University of British Columbia.
