The First Genomic Resources for Phymatotrichopsis omnivora, a Soilborne Pezizomycete Pathogen with a Broad Host Range

Phymatotrichopsis omnivora is a destructive plant pathogen causing root rot disease of alfalfa, cotton, pecan, grape, and many other important dicotyledonous species. A member of the family Rhizinaceae, in the class Pezizomycetes, P. omnivora is a soilborne ascomycete fungus that is difficult to maintain in culture, currently genetically intractable, and for which there are no publicly available genomic resources. We have generated draft genome sequences of four P. omnivora isolates obtained from cotton and alfalfa, growing in Texas and Oklahoma. These genome sequences will provide new insights into the biology of the fungus, including the factors responsible for its broad host range and pathogenicity.
