a Mercator metabolic categories showing evidence of significant enrichment (red) or depletion (blue) in the diurnal study. Transcripts were sorted by phase into one of four time bins; ‘sunrise’ (4 – 10 am), ‘midday’ (10 am – 4 pm), ‘sunset’ (4 – 10 pm), and ‘midnight’ (10 pm – 4 am). Shading is scaled by the –log2 value of the P-value, following an FDR correction of 0.05. b Metabolic pathways showing significant enrichment (red) or depletion (blue) in four photoperiod categories: short (5-Nov to 4-Feb), spring (5-Feb to 6-May), long (7-May to 5-Aug), and fall (6-Aug to 4-Nov). Shading is scaled by the –log2 value of the P-value, following an FDR correction of 0.05
