Exploiting long read sequencing to detect azole fungicide resistance mutations in Pyrenophora teres using unique molecular identifiers

This study uses long-read sequencing to detect azole fungicide resistance mutations in Pyrenophora teres, identifying all known mutations in complex samples.

Workflows for detecting fungicide resistance in net form and spot form net blotch pathogens

This study develops phenotyping and genotyping workflows to detect fungicide resistance in Pyrenophora teres pathogens, identifying prevalent resistance alleles in South and Western Australia.

Emergence of resistance to succinate dehydrogenase inhibitor fungicides in Pyrenophora teres f. teres and P. teres f. maculata in Australia

This paper identifies novel mutations in the Sdh complex genes of Pyrenophora teres isolates in Australia that confer resistance to SDHI fungicides, with specific mutations linked to reduced in vitro sensitivity.

Proteomic analysis revealed that the oomyceticide phosphite exhibits multi-modal action in an oomycete pathosystem.

This study uses proteomics to show phosphite affects both the oomycete pathogen and its host through multiple mechanisms, including metabolic disruption and immune response changes.

Species hybridisation and clonal expansion as a new fungicide resistance evolutionary mechanism in Pyrenophora teres spp.

The paper identifies a natural hybrid of Ptt and Ptm fungi with azole resistance, showing recombination and clonal expansion contributing to fungicide resistance in barley.

Detection of Ramularia collo-cygni from barley (Hordeum vulgare) in Australia using triplex quantitative and digital PCR

This study develops a triplex PCR assay for specific detection of Ramularia collo-cygni in barley, confirming its presence across southern Australian barley-growing regions.

Parallel evolution of multiple mechanisms for demethylase inhibitor fungicide resistance in the barley pathogen Pyrenophora teres f. sp. maculata

This study identifies multiple independent mechanisms of DMI fungicide resistance in Pyrenophora teres f. sp. maculata, including promoter insertions and amino acid substitutions.
