Phylogenetic trees of E. curvula RNA-dependent DNA methylation proteins in A. thaliana and Z. mays. (a) AGO, (b) DMT, and (c) CHR proteins from Arabidopsis and maize were retrieved from the The Arabidopsis Information Resource (TAIR) and the Maize Genetic and Genomic Database (MaizeGDB), respectively. The amino acid sequences of E. curvula were obtained from our floral reference transcriptomes. The unrooted neighbor-joining tree was constructed using MEGA v6.0.
