Figure 4From: MicroRNAs and their putative targets in Brassica napusseed maturationTemporal expression patterns of conserved miRNAs and variants. Hierarchical clustering of the 80 most abundant miRNA/variants during seed development and at flowering (FL). The color indicates the relative expression level: Blue-low, yellow-medium and red-high. Four major expression patterns (A1 – A4) are identified.Back to article page
