Current research and/or projects

  • Fungal and Bacterial Biosystematics - bridging taxonomy and “omics” technology in agricultural research and regulation; J-002272; Project lead(s): Sarah Hambleton, Keith Seifert; Budgets: $2,495,000 ($157,500 for ML); Duration 2019/04/01 – 2024/03/31; Proposal stream: STB Annual Call for RDT Proposal

Research and/or project statements

Identify species and understand genetic variability of plant related fungal pathogens to facilitate the crop breeding program for developing disease resistant cultivars that will increase agriculture productivity; Understand the population genetic structure of plant pathogens to provide information for deploying environment-friendly disease control strategies and enhancing environmental performance; increase knowledge on systematics, genomics, diagnostics, chemotyping and distribution of toxin genic fungi (i.e. Claviceps spp.) in grains to build foundation for food quality control through bio-surveillance, domestic legislation/regulations, and risk evaluation.
