Project Number: 1275-22000-198-01
Project Type: Reimbursable

Start Date: Oct 01, 2000
End Date: Sep 30, 2005

Objective:
Provide technical support for research on the systematics of coelomycetous fungi in the genera Phomopsis, Stagonospora and related fungi of plant quarantine significance. Provide space, facilities, and resources to the two APHIS mycologists housed at SBML.

Approach:
Strains of Phomopsis from economically important hosts are studied to determine and define taxa using microscopic, cultural, and molecular characteristics. Characteristics of host-specificity and pathogenicity are determined often through collaborators. Sexually derived strains are included where possible. Genes to be sequenced include the large subunit of the ribosomal DNA and portions of the translation elongation factor. Groupings based on phylogenetic analyses are correlated with morphological and biological characteristics. A similar approach is taken to understanding the phylogenetic systematics of Stagonospora and other grass-crop pathogens. Space and facilities are provided to the two APHIS mycologists who also have access to fungal herbarium specimens and reference and database resources.
