- •
Species number and genetic differences of switchgrass rusts were examined.
- •
Phylogenetic analyses of partial-ITS sequence revealed two monophyletic clades.
- •
Clade I included taxa identified to Puccinia emaculata.
- •
Clade II taxa were identified morphologically to Uromyces graminicola.
- •
An unknown rust was also found infecting the cultivar Summer in Nebraska.
