The 15 gypsy moth genes having the largest digital gene expression level perturbations following Bacillus thuringiensis infection.

The FoldDiff column indicates the fold change in expression level; Direction whether the gene was up- or down-regulated; Control and Bt midgut provide sample-specific digital expression counts normalized to the total number of reads per sample; and NRgene describes the best homolog identified in the NR protein sequence database for the associated transcript.
