Phylogenetic analysis of amino acid sequences of HIKs from Magnaporthe oryzae and selected fungal species. The GeneBank accession numbers of the analyzed proteins or the gene name from the Magnaporthe comparative database are shown in curved brackets and trivial names were shown in square brackets. A preceding hash tags the protein sequences of M. oryzae. Related clades of the dendrogram have the same color and group number (roman numerals, according to Catlett et al. 2003). Bf (Botryotinia fuckeliana), Ca (Candida albicans), Ch (Cochliobolus heterostrophus), Ec (Escherichia coli), En (Emericella nidulans), Gm (Gibberella moniliformis), Mg (Mycosphaerella graminicola), Mo (Magnaporthe oryzae), Nc (Neurospora crassa), Sc (Saccharomyces cerevisiae). HIK, histidine kinases.
