Systematics

In the Bradshaw Lab, our research is fundamentally centered on systematics, with a special emphasis on cataloging the biodiversity of fungi. We have described over 30 new species of fungi, many of which have been discovered in unique and frequently visited locations such as university campuses and botanical gardens. To date, only about 150,000 species of fungi have been formally accepted out of an estimated ~3 million, highlighting a significant gap in our understanding of fungal biodiversity.

A main topic of our research addresses key taxonomic, phylogenetic, and ecological questions, within a prevalent group of plant pathogenic fungi known as the powdery mildews. Powdery mildews are obligate parasitic ascomycetes in the Erysiphaceae family. These fungi are some of the most prevalent and economically significant plant pathogens, affecting over 10,000 angiosperm species. Recent research underscores their immense ecological impact, further emphasizing the importance of our systematic and taxonomic efforts in understanding and managing these fungi.

By cataloging and studying these diverse fungal species, we are not only contributing to the broader knowledge of fungal biodiversity but also addressing the critical need for diversity in fungal biology research. Through our efforts, we aim to enhance understanding and management of fungal species, underscoring the importance of systematic studies in uncovering the hidden diversity of our natural world.
