^aBoldface data indicate transcripts encoding proteasome subunits that are elevated by ≥2 log₂ fold in at least one NP transcriptome.

^bData for proteasome subunit transcripts are divided into data for transcripts encoding proteasome subunits that are elevated ≥2 log₂ fold in the transcriptome produced into response to at least one NP and the remaining proteasome subunit transcripts for comparison.
