Figure 3.
Phylogenetic relationships and protein motifs of ZmnMAT1 and its homologs. The ZmnMAT1 protein and its homologs from NCBI were aligned by ClustalW, and the phylogenetic tree was constructed using MEGA 5.0 software. Distances were estimated with a neighbor-joining algorithm, and bootstrap support is indicated to the left of branches. Scale bar indicates the average number of amino acid substitutions per site. RT, X and D-En motifs represent the reverse transcriptase domain, an RNA binding and splicing domain, and DNA-binding endonucleases domain, respectively.
