This study identifies 40 QTL for net blotch resistance in barley using haplotype analysis, revealing shared and distinct genetic mechanisms between two disease forms.

This study identifies SnTox8-mediated reprogramming of wheat defence signalling through transcriptomic analysis of two wheat genotypes, revealing mechanisms of effector-triggered susceptibility.

The paper clones AvrYr7, an effector gene in wheat stripe rust, and identifies variants that evade recognition by the resistance gene Yr7 through sequence and expression differences.

The paper identifies an AvrPstB48 effector from stripe rust fungus that triggers defence responses in wheat but does not directly correlate with disease outcomes.

The paper uses long-read genomics to study dikaryotic fungus genome biology, revealing nuclear-specific evolution and allele-specific expression.

This paper identifies haploblocks associated with multiple disease resistance in wheat using a diversity panel and demonstrates their potential to improve resistance through haplotype stacking.

The paper analyzes the genetic composition and history of the bread wheat D genome using a pangenome of its donor species, revealing contributions from discrete subpopulations of Aegilops tauschii.

The paper shows that somatic nuclear exchange in Puccinia triticina generates genetic diversity, leading to new strains through repeated shuffling of haploid nuclei between clonal lineages.

This study identifies Rph7, a barley resistance gene against leaf rust, as a putative NAC transcription factor involved in basal defence activation.

The paper identifies and corrects phase switches in Hi-C data for dikaryotic fungus assemblies using Nanopore and HiFi sequencing, showing HiFi's superiority in phasing low heterozygosity genomes.

This paper clones four stem rust resistance genes in wild diploid wheat using association genetics and R gene enrichment sequencing within six months.

This study assesses the functionality of cloned wheat Sr genes in barley, finding that Sr22, Sr33, Sr35, and Sr45 confer effective resistance against stem rust caused by Puccinia graminis f. sp. tritici.
