Gene and protein structure of the Hex1 homolog of Verticillium dahliae, and phylogenetic analysis. (A) Gene structure of locus VDAG_01749. Mapping of RNA-seq reads on the genomic sequence supports the definition of an intron that can be spliced in two alternative ways (red and blue reads, respectively) to produce two highly similar isoforms of the protein. (B) Prediction by homology modeling of the tertiary structure of V. dahliae Hex1 and comparison to the solved structure of its Neurospora crassa homolog (PDB 1KHI). (C) Maximum likelihood phylogenetic tree of Hex1 homologs across several Pezizomycotina orders of varying phylogenetic distances from Verticillium.
