Fig. 1From: Characterization of cadmium-responsive MicroRNAs and their target genes in maize (Zea mays) rootsAltered expression of miRNAs in plants in response to heavy metal stress. Green indicates down-regulation, and red indicates up-regulation. Quantitative data of miRNA abundance in diverse plant species were collected; green indicates down-regulated miRNAs, red indicates up-regulated miRNAsBack to article page
