Abstract

The systematics of Alternaria and allied genera has been traditionally assessed based upon conidial morphological characteristics. This method of systematic evaluation of organismal relationships has caused much taxonomic flux for Alternaria and related genera within Stemphylium, Embellisia, Nimbya, Undifilum, and Ulocladium. The present study utilizes extensive taxon sampling from 176 species spanning ten genera and molecular phylogenetic analyses of ten protein-coding loci. Results from this work reveal that three genes have experienced substantial substitution saturation at the third codon position and two other genes do not possess sufficient levels of phylogenetic informativeness to delineate the order of divergence of many previously described Alternaria species-groups. The combined analysis of five phylogenetically informative protein-coding genes strongly supports nine distinct phylogenetic lineages of Alternaria. Eight asexual lineages cluster as a strongly supported monophyletic group sister to the genus Ulocladium, while the sexual members of the infectoria clade cluster with other sexual genera. This work proposes to elevate all nine well-supported lineages of Alternaria to the taxonomic status of Section. Evolutionary relationships among Alternaria and closely related genera are discussed.
