  • Overall Goals - To develop basic information about the systematics of plant pathogenic fungi. This knowledge is critical for making sound plant quarantine decisions to prevent the introduction of new plant pathogens and for developing effective disease management strategies.
  • Molecular Systematics of the Genus Tilletia - Use DNA sequence data to investigate the relationships of bunt fungi on cultivated and wild grains with the goal of developing a phylogenetic framework in which species and generic concepts can be determined and refined. Morphological, nomenclatural and molecular data are being integrated in an on-line identification system for specialists and non-specialists to identify or obtain information about bunt fungi.
  • Molecular Systematics of Diaporthalean Fungi - Analyze relationships among the sexual and asexual states of Diaporthe/Phomopsis and related canker-causing fungi in the Diaporthales. DNA sequence data are being used to determine family- and generic-level relationships. In addition, multiple gene phylogenies are used to determine phylogenetic species limits, particularly in the Diaporthe/Phomopsis complex and species in the Gnomoniaceae.
