  1. tRNA modifying genes from S. cerevisiae or E. coli were used for BLAST search in TAIR database to find homologous genes in Arabidopsis thaliana. Arabidopsis genes for each modified nucleosides detected in this study is listed and gene used in query was shown in bracket. For multiple gene homologs found in Arabidopsis the query gene is shown in bracket next to the last gene. Genes for m2A and m6A modification were not available, TsaA for m6t6A did not give any homologous genes in Arabidopsis. Predicted subcellular localization of gene products was shown when at least two prediction programs gave the same result (Additional file 2).
