Fig. 3From: microRNA-dependent gene regulatory networks in maize leaf senescenceExpression levels of senescence-associated miRNAs in the leaves of inbred lines ELS-1 and Yu87-1. In total, 16 differentially expressed miRNAs were identified as candidate SA-miRNAs. Red indicates up-regulated gene expression and blue represents down-regulated. The scale is log2 (fold-change)Back to article page
