Distribution of global changes in transcript and metabolite levels and enzyme activities during the diurnal cycle and an extended night (XN). Distribution of changes in (a) 2,433 transcripts assigned to metabolism, (b) 23 enzyme activities and (c) 140 metabolites after 2, 4, 8, 24, 48, 72 and 144 h of extension of the night. Transcript levels were not determined at 72 and 144 h. Distributions are expressed as probability densities and were calculated with R using the function 'density', which computes kernel density estimations. The same bandwidth of 0.2 was used for all datasets.
