Introduction
Oadi's main research project is I led the wheat transgenic project to validate the resistance genes as multi or single genes in the transgenics line in greenhouse and field. Also, screening a universal wild types collection of wheat and barley to discover new sources of resistance genes against plant diseases. Participating in screening breeding material lines of wheat and barley against rust diseases (Stem, Stripe, and Leaf rust) and other foliar diseases like FHB, SB, NB, BLS, and PM.

Stripe rust (Puccinia striiformis f. sp. tritici (Pst)) is one of the most devastating fungal diseases of durum wheat (Triticum turgidum L. var. durum Desf.). Races of Pst with new virulence combinations are emerging more regularly on wheat-growing continents, which challenges wheat breeding for resistance. This study aimed to identify and characte...

Abstract: Stripe rust (Puccinia striiformis f. sp. tritici (Pst)) is the most devastating fungal disease of durum wheat (Triticum turgidum L. var durum Desf.). Unfortunately, stripe rust races with single and combination gene virulences are emerging more regularly on wheat-growing continents, which challenges wheat breeding for resistance. This stu...

The wild relatives and progenitors of wheat have been widely used as sources of disease resistance (R) genes. Molecular identification and characterization of these R genes facilitates their manipulation and tracking in breeding programmes. Here, we develop a reference-quality genome assembly of the wild diploid wheat relative Aegilops sharonensis...

Stripe rust is a devastating disease in wheat that causes substantial yield loss around the world. The most effective strategy for mitigating yield loss is to develop resistant cultivars. The wild relatives of wheat are good sources of resistance to fungal pathogens. Here, we used a genome-wide association study (GWAS) to identify loci associated w...

Aegilops tauschii, the diploid wild progenitor of the D subgenome of bread wheat, is a reservoir of genetic diversity for improving bread wheat performance and environmental resilience. Here we sequenced 242 Ae. tauschii accessions and compared them to the wheat D subgenome to characterize genomic diversity. We found that a rare lineage of Ae. taus...

Wild barley (Hordeum vulgare ssp. spontaneum) is a rich source of diverse alleles for many traits that are important for barley improvement. To exploit barley's progenitor for disease resistance alleles, we assembled an ecogeographically diverse collection of 287 accessions (the Wild Barley Diversity Collection or WBDC) and evaluated it for reactio...

Breeding wheat with durable resistance to the fungal pathogen Puccinia graminis f. sp. tritici (Pgt), a major threat to cereal production, is challenging due to the rapid evolution of pathogen virulence. Increased durability and broad-spectrum resistance can be achieved by introducing more than one resistance gene, but combining numerous unlinked g...

Stem rust, caused by the fungal pathogen Puccinia graminis f. sp. tritici, is one of the world’s most important diseases of wheat (Triticum aestivum). Due to its rapid co-evolution with wheat, deployment of new varieties with a stack of multiple stem rust resistance genes sourced from cultivated and wild wheat are needed to control the disease. In...

Leaf rust of wheat, caused by the obligate biotrophic pathogen Puccinia triticina, is the most common among the three rusts of wheat worldwide. Wheat leaf rust epidemics can cause significant yield losses, and the most economical method to control them is breeding for genetic resistance to this pathogen. There are over 70 leaf rust resistance genes...

Stem rust (Puccinia graminis f. sp. tritici, Pgt) and leaf rust (Puccinia triticina, Pt) are two of the most important diseases of wheat worldwide. Genetic resistance offers the best means of control for these diseases, but often lacks durability due to changes in pathogen virulence. To enhance durability of rust resistance in wheat, a multi-transg...
