Modes of Action of Plant AGO Proteins. (A) AGO1 binds miRNAs or trans-acting small interfering RNAs and cleaves target mRNAs. (B) AGO1 binds miRNAs and inhibits the translation of target mRNAs. (C) Arabidopsis AGO10 and rice AGO18 act as decoys for miR165/166 and miR168, respectively. (D) AGO4 binds heterochromatic siRNAs or long miRNAs and mediates DNA methylation. (E) AGO2 binds DSB-induced sRNAs and mediates DSB repair. (Reproduced from Fang and Qi [2016], Figure 2.)

Striking Differences in Genome and Epigenome Organization in Different Plant Species. The organization of genes (green) and TEs (pink) is shown for portions of the maize and Arabidopsis genomes, along with the relative abundance of chromatin modifications often associated with heterochromatin: CHG DNA methylation (red), CHH DNA methylation (black), and H3K9me2 methylation (blue).
