Diagnostic microsatellite markers for the barley net blotch pathogens, Pyrenophora teres f. maculata and Pyrenophora teres f. teres

摘要

The barley net blotch pathogen Pyrenophora teres occurs in two forms, evident as spot (P. teres f. maculata) or net (P. teres f. teres) type symptoms. The two forms can be difficult to differentiate based on disease symptoms or spore morphology. Here we report nine simple sequence repeat markers that reveal differences between the two forms, providing diagnostic markers that are potentially useful.
