  1. 1For each gene, the first number indicates the logFC of a certain condition compared to LB; RPKM values are shown in parentheses. Significantly differentially expressed genes are in bold (i.e., p values ≤ 0.05 in edgeR). For a graphic version, indicating the magnitude of the absolute value of logFC in shades of grey, see Additional file 4.
