  1. aThe code for the gene expression pattern is “day”, main effect factor level, direction of the main effect. D1 refers to samples harvested during cold exposure and their controls. D4 refers to samples harvested 24 h after cold exposure and their controls. CG60_UP indicates a significant, positive effect of CG60. CG60_DOWN indicates a significant, negative effect of CG60
  2. bPathways with b at the end of the description were underrepresented amongst the gene set
