Fig. 4From: Genome-wide analysis of AGO, DCL and RDR gene families reveals RNA-directed DNA methylation is involved in fruit abscission in Citrus sinensisExpression levels of (a) CsAGO, (b) CsDCL and (c) CsRDR genes. Analyzed tissues were root, leaf, flesh, peel and embryo. Normalized expression for each gene family is represented with different color intensity, ranging from white to redBack to article page
