Figure S2: Investigation of Pol IV-dependent sRNAs in dcl1/2/3/4 quadruple mutant from Arabidopsis RNA polymerase IV generates 21–22 nucleotide small RNAs that can participate in RNA-directed DNA methylation and may regulate genes

Heatmap of read counts of 15-34 nt small RNAs from Pol IV-dependent clusters in various dicer mutant combinations including the dcl1/2/3/4 quadruple mutant from a seedling dataset (18). dcl1/2/3/4 refers to the dcl1/dcl2/dcl3/dcl4 quadruple mutant.
