The analysis for the presence of MTases was carried out using the complete sequence for Coffea canephora from Coffee Genome Hub (http://coffee-genome.org/), for Arabidopsis thaliana from TAIR10 (http://www.arabidopsis.org/) and for Solanum lycopersicum, Vitis vinífera, Theobroma cacao, Brassica rapa, Glycine max, and Oryza sativa from PHYTOZOME v10.2 (http://phytozome.jgi.doe.gov/pz/portal.html). We took into account all of the sequences that proved to contain more than one of the following functional annotations: PFAM/PF00145C-5/cytosine-specific DNA methylase, DNA (cytosine-5-)-methyltransferase [EC:2.1.1.37] and (GO:0008168) [QuickGo from European Bioinformatics Institute].
