Number of quantified and regulated genes in individual approaches.

1The annotated R. sphaeroides 2.4.1 genome (http://img.jgi.doe.gov/cgi-bin/w/main.cgi) contains 4304 open reading frames. Numbers of mRNAs/proteins that were unambiguously quantified are depicted.
2Numbers (#) and percentages (%) for regulated genes are given. Percentages were calculated relative to quantified mRNAs/proteins. Genes were considered to be regulated when log2 ratios (stress versus reference) were ≥0.8 (up-regulated) or ≤−0.8 (down-regulated) with p-values <0.05.
