From: Altered expression profiles of microRNA families during de-etiolation of maize and rice leaves
Fold-changes of expression levels of conserved miRNA families during de-etiolation. The color bar represents log(e) fold-change of TPQ (transcripts per quarter million) values of corresponding time point to control sample. If TPQ equals 0, a small value 0.001 was used instead in the calculation. Abbreviation of species name and time during de-etiolation in hours were listed in the bottom panel
