Sclerotinia sclerotiorum is a fungal plant pathogen and the causal agent of lettuce drop, an economically important disease of California lettuce. The structure of the S. sclerotiorum mating type locus MAT has previously been reported and consists of two idiomorphs that are fused end-to-end as in other homothallics. We investigated the diversity of S.(More)
The Fusarium solani species complex (FSSC) includes important root pathogens of soybean in the United States, but the evolutionary lineages associated with soybean root rot are unknown. A multilocus phylogeny based on 93 isolates from soybean and pea roots from North Dakota and Minnesota revealed that root rot was associated with three known phylogenetic(More)
Labyrinthula terrestris, the causal agent of rapid blight disease in cool-season turfgrasses, is the first Labyrinthula species found to be associated with higher plants in terrestrial ecosystems. An initial study suggested a single common genotype associated with turfgrass in the US, but a later study revealed genetic diversity in this pathogen. In the(More)
