Wheat is one of the most important food crop cultivated across the globe which ensures sustainability and food security to massive world's population, but its production is threatened by both biotic factors like rust (caused by species) and abiotic stresses such as salinity. In this study, 41 salt-tolerant wheat lines were screened for rust resistance at both seedling and adult plant stages. Rust resistance genes were characterized through gene matching technique and molecular markers analysis.

- - The gene Sr65, found on chromosome 1A of the Indian wheat landrace Hango-2, provides crucial resistance against the stem rust pathogen Puccinia graminis f. sp. tritici (Pgt), protecting wheat crops in multiple regions including Australia, India, Africa, and Europe.
- - Research on a recombinant line population of Hango-2 discovered two resistance genes: a new gene termed SrH2 and an existing one called Sr26; SrH2 was mapped to a specific region on chromosome 1A and is valuable for developing resistant wheat varieties.
- - The markers associated with SrH2, KASP_12147 and sunCS_265, show high polymorphism in
spp. causing rust diseases in wheat and other cereals secrete several specialized effector proteins into host cells. Characterization of these proteins and their interaction with host's R proteins could greatly help to limit crop losses due to diseases.
