Barley pathogen genome assembled
A genome map for the important barley fungal pathogen, Pyrenophora teres f teres has been assembled by researchers from a consortium of Australian universities. P teres f teres is the causative agent of the net form of net blotch, which causes yield losses of 10-40%. Australian losses to the fungus are valued at around Aus$62 million (US$61 million at the current rate) annually despite control costs of Aus$246 million (US$243 million), the researchers note. The availability of a genome assembly that provides suites of genetic markers to characterise and isolate genes associated with net blotch pathogenicity, host resistance and plant-microbe interactions in general, the study says. Details of the research were published in the UK journal, Genome Biology.
