Significance of Recent Discoveries in Stripe Rust Management

Abstract

Stripe rust in wheat is the most problematic disease damaging the produce severely in wheat growing regions. In this paper findings in recent past related to yellow rust with reference to their application in the management of disease have been debated. In this regard various aspects of breeding for resistance were focused. Pathogen has adopted under the changed climatic scenario brings and disease is observed in the regions where it did not exist earlier. Rising temperatures has increased the irregularity and concentration of precipitation, causing the spread and severity of rust diseases. NB-LRR proteins are expected to play a substantial part in advanced agriculture where yield is the primary goal for screening. Biotechnology has revolutionized in biological sciences including Plant Pathology. Experts are studying the biochemical nature and the signals involved in, a plant's responses to pathogen attack and development of disease. Plant resistance genes are being engineered into plants to defend them from plant diseases.

Modern Approaches to Enhancing Rust Resistance in Wheat Leading to Global Food Security

“…The characteristic symptom of stem rust is the appearance of reddish-brown, elongated pustules on the stems, leaves, and glumes of the wheat spike. Severe infections can cause stem breakage and lead to complete yield loss (Afzal et al, 2015). Stripe rust is also known as yellow rust due to the appearance of yellowish-orange pustules on the leaves.…”

“…Management of rust diseases in wheat involves a combination of cultural practices (Figueroa et al, 2018), chemical control (Afzal et al, 2020;Carmona et al, 2020), and genetic resistance (Afzal et al, 2018;2022a). Planting rust-resistant wheat varieties is one of the most effective and sustainable approaches to managing rust diseases (Afzal at al., 2015;2022b). Breeding programs have successfully incorporated resistance genes from various sources to develop wheat varieties with durable resistance against different rust pathogens (Ellis et al, 2014;Ijaz et al, 2023).…”

Determination of Relationship of Environmental Factors With Stripe Rust in Wheat

“…The novel races of Puccinia striiformis f.sp. tritici (PST) have considerably increased adaptation to warmer temperatures and consequently endure to cause disease epidemics (Afzal et al, 2018;Milus et al, 2009). The damaging epidemics have happened in Middle East, Central Asia, Western Asia, China, Northern and Eastern Africa in the recent past (Solh et al, 2012).…”
