Comparative analysis of Htf1 protein in three Fusarium species.

(A) Sequence alignment of the homeodomain in Htf1 homolog of F. graminearum (FgHtf1), F. verticillioides (FvHtf1), F. oxysporum (FoHft1) and M. oryzae (MoHtf1) was performed using Clustal W and Boxshade (http://bioweb.pasteur.fr/seqanal/interfaces/boxshade.html). The conserved amino acid residues are shaded black, whereas similar residues are shown in gray. Consensus amino acids are marked with asterisk (*). (B) Homology matrix analysis of Htf1 homeodomain (left box) and whole protein (right box) in three Fusarium species and M. oryzae by DNAMAN software. Numbers (%) indicate protein identity.
