Here, we identify an H3K9me2-binding protein, Agenet domain (AGD)-containing p1 (AGDP1), in Arabidopsis thaliana . Here we find that AGDP1 can specifically recognize the H3K9me2 mark by its three pairs of tandem AGDs. We determine the crystal structure of the Agenet domain 1 and 2 cassette (AGD12) of Raphanus sativus AGDP1 in complex with an H3K9me2 peptide. In the complex, the histone peptide adopts a unique helical conformation. AGD12 specifically recognizes the H3K4me0 and H3K9me2 marks by hydrogen bonding and hydrophobic interactions. In addition, we find that AGDP1 is required for transcriptional silencing, non-CG DNA methylation, and H3K9 dimethylation at some loci. ChIP-seq data show that AGDP1 preferentially occupies long transposons and is associated with heterochromatin marks. Our findings suggest that, as a heterochromatin-binding protein, AGDP1 links H3K9me2 to DNA methylation in heterochromatin regions.
