Fig. 1From: Identification of miRNAs associated with dark-induced senescence in Arabidopsis Experimental system and dark-induced senescence phenotype of leaves. Leaves from the 6th to 12th rosettes of plants were induced to senesce by dark-treatment for 2, 4 or 6 d. 0 d before treatment represents WT. For DP, the entire plant was maintained in constant dark. For IDL, the leaves on the rest of the plant remained in the light. White arrows indicate the covered leavesBack to article page
