Research Project: Sequencing and Analysis of Fusarium Genomic Diversity

Location: Bacterial Foodborne Pathogens & Mycology Research Unit

Project Number: 3620-42000-046-01
Project Type: Specific Cooperative Agreement

Start Date: Jun 01, 2012
End Date: May 31, 2014

Objective:
The major objective of this agreement is to generate complete genome and transcriptome sequences for representative species within the genus Fusarium. The fungal genus Fusarium includes devastating plant pathogens, threatening practically every major food crop around the world. In addition, many species produce metabolites that are highly toxic to animals and plants. Fusarium is one of the most extensively studied fungal genera, with a highly advanced state of accumulated knowledge with respect to its basic biology, pathology, and species-level phylogeny. However, there is an increasing need to develop a comparative genomic framework and associated tools that enable a global understanding of the biology, diversity, ecology, pathology, and evolution of the most agriculturally important groups within this genus. We aim to create such a framework by generating complete genome and transcriptome sequences for representative fusaria in order to: (a) improve diagnosis and detection; (b) improve understanding of the pathology and evolution of Fusarium; (c) facilitate the quick translation of basic knowledge to disease and toxin management; and (d) preserve and share accumulated data, ‘experience-based’ knowledge, and tools for future research and education.

Approach:
In order to achieve a critical next-step in pathogen genomic analyses, we intend to sequence, assemble, and annotate the genomes of 32 fusaria within the Fusarium graminearum and Fusarium fujikoroi species complexes. These groups include the major etiological agents of Fusarium head blight and ear rot diseases, as well as the most important producers of trichothecene and fumonisin mycotoxins. The resulting genome sequences will be used to sytematically catalog the inventory of genes and functional elements in these fungi, characterize the distribution and function of secondary metabolite gene clusters, and to develop an integrated Fusarium diagnostics and management resource.
