Four Reference Quality Genome Assemblies of Pyrenophora teres f. maculata: A Resource for Studying the Barley Spot Form Net Blotch Interaction

Pyrenophora teres is the causal agent of net blotch, the most devastating foliar disease of barley. In nature, net blotch is seen in two forms, net form net blotch, caused by P. teres f. teres, and spot form net blotch, caused by P. teres f. maculata. To date, 11 P. teres f. teres genomes have been sequenced and deposited in publicly available repositories, but only one P. teres f. maculata genome has been publicly deposited. Here, we present four additional reference-quality full-genome sequences of P. teres f. maculata isolates with good geographical and phenotypic diversity, with accompanying RNA sequencing-based genome annotations. These additional P. teres f. maculata genomes will aid in the understanding of the genomic complexities of this important barley pathogen.

Automated summary

Pyrenophora teres is the causal agent of net blotch, the most devastating foliar disease of barley, with two forms in nature, net form net blotch and spot form net blotch. While 11 P. teres f. teres genomes have been sequenced and stored, only one P. teres f. maculata genome is publicly available. This study presents four additional high-quality P. teres f. maculata full-genome sequences to enhance understanding of the genomic complexities of this important barley pathogen.
