Sequence production for the SNP discovery step. Sequence production for the SNP discovery step for each of white spruce and black spruce.

Production parameter	White spruce	Black spruce	In common between the two species
Number of genes successfully amplified and resequenced	487	462	457
Number of genes with orthologous SNPs	394	355	279
Total number of orthologous SNPs	1102	959	45
Number of genes on species-specific SNP array	425	348	273
Number of resequenced SNPs on species-specific SNP array	730	768	14
Number of in silico SNPs1 on species-specific SNP array	38	-	-

¹ in silico SNPs were detected in aligned ESTs derived from white spruce cDNA libraries. The resource is described in Pavy et al. [48]. For black spruce, all assayed SNPs were obtained after resequencing from genomic DNA.
