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, 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 isolates obtained from cotton and alfalfa, growing in Texas and Oklahoma.

Phymatotrichopsis omnivora is a broad host, soil-borne necrotrophic fungal pathogen that infects over 2,000 dicotyledonous plants. The molecular basis of such broad host range is unknown.

Disease resistance genes in plant cultivars can break down in the field due to the evolution of pathogens under high selection pressure. Thus, the protection of crop plants against pathogens is a continuous arms race.
