Clarification of the phylogeny, evolution, and speciation of the Oomycetes
White blister rust (Albuginales) and downy mildew (Peronosporales) of Oomycetes are causing significant impacts on agriculture in terms of economic and environmental losses. Taxonomic complexity of the fungi-like groups has recently increased by unclear generic or species concepts and so far uncovered evolutionary history. My research interests are 1) to clarify phylogenetic relationships of genera and species within the Albuginales and Peronosporales using molecular and morphological approaches, with a particular emphasis on placing rare species in the evolutionary context of the Albuginaceae, 2) to determine their phylogenetic placement within the Oomycetes, and 3) to evaluate two species concepts (broad vs. narrow host ranges) co-existing for economically important crops. This will be a keystone contribution toward assembling the Oomycetes tree of life. In addition, the results of the multigene barcoding will also offer a tool for exact species delimitation and rapid identification of unknown or economically important species based on a comprehensive phylogenetic framework.
