Figure 2.

Photoperiod-dependent changes in global gene expression: (a) in response to photoperiod 12 h/12 h, the transcriptional regulation of many coffee leaf genes are down- or up-regulated when compared at the photoperiod 8 h/16 h at different ZT (ZT0 = dawn, ZT12 = dusk) (color brown = down; color orange = up). (b) Comparison of gene expression between ZT0 and all other ZT was made for each of the two photoperiods. Number of DEGs compared with ZT0 at 12 h/12 h photoperiod (orange color) and DEGs compared with ZT0 at 8 h/16 h photoperiod (brown color) among time points is represented. Number of common oscillating genes between 8 h/16 h and 12 h/12 h compared with ZT0 is represented in white color.
