Fig. 7From: Conservation and divergence of small RNA pathways and microRNAs in land plantsHeatmap for conserved miRNA candidates. Each row represents a miRNA family. Colors indicate the scaled expression levels of these miRNA families (log2(RPM)). Rows are divided into five groups: class I miRNA candidates were found at high levels in all species; class II miRNA candidates were found in most ferns but few or no lycophytes; class III miRNA candidates were detected at high levels in multiple species in both lycophytes and ferns; class IV miRNA candidates were detected mainly in lycophytes; and class V miRNA candidates were at high levels in specific speciesBack to article page
