A new multiyear study reveals wheat disease losses totaling $2.9 billion in the US and Canada between 2018 and 2021. The top three yield-reducing pathogens were fusarium head blight, stripe rust, and leaf rust.
Traditional Asian wheat varieties harbor multiple genes conferring yellow rust resistance, a devastating disease threatening global bread wheat production. These findings highlight the importance of preserving genetic diversity and traditional farming practices to combat diseases and ensure food security.
The latest focus issue of Molecular Plant-Microbe Interactions explores the molecular, cellular, and genomic details of cereal crop diseases, highlighting key research on plant-pathogen interactions. Groundbreaking work has advanced the field, offering new insights into disease resistance and management strategies.
Researchers have cloned the wheat rust resistance genes Lr9 and Sr43, revealing that they encode unusual kinase fusion proteins. This breakthrough enables new options for addressing disease resistance in bread wheat and could lead to heat-resistant versions of the Sr43 gene to adapt to climate change.
Experts warn that fungal disease in crops could lead to unprecedented challenges in food production, causing losses equivalent to enough food for millions of people. The increasing prevalence of fungal infections is due to rising temperatures and the development of resistance to antifungals.
Researchers at King Abdullah University of Science & Technology (KAUST) have identified a stem rust resistance gene in Aegilops sharonensis and transferred it to common wheat. The new transgenic wheat lines show high levels of resistance to the stem rust pathogen, providing hope for mitigating the devastating effects of climate change.
Researchers have identified a key gene that confers stripe rust resistance in bread wheat, providing hope for improving crop yields and ensuring global food security. The discovery was made possible by the assembly of the highest-quality genome to date for bread wheat using advanced DNA sequencing techniques.
A 13-year analysis of wheat rust outbreaks in Ethiopia reveals long-term trends and hotspots, potentially leading to improved surveillance and control efforts. The study found a 'boom-and-bust' outbreak cycle due to genetic resistance breakdowns, emphasizing the importance of sustained pest management for food security.
Scientists have identified specific genes that confer nonhost resistance to wheat leaf rust in barley, a breakthrough that could transform the breeding of durable disease-resistant cereal crops. This discovery has the potential to improve global food security by providing a solution to one of the biggest problems in wheat production.
A team of scientists has developed a modelling system to predict the spread of devastating wheat rust disease, identifying Yemen as a potential hub for long-distance dispersal to India and Pakistan. The research highlights the risk of global economic loss from wheat stem rust, currently estimated at $1 billion annually.
A new surveillance technique has revealed a diverse population of wheat rust fungus in the UK, with some strains being more aggressive and virulent than others. The findings highlight the threat posed to global food security due to climate change and increased globalization.
Aggressive new strains of stem and stripe rust have decimated up to 40% of farmers' wheat fields globally. Developing resistant varieties and improving country capacity are key strategies to combat the problem.
A new study by Oregon State University and other institutions reveals that invading diseases can accelerate their spread, posing serious concerns for human diseases and a new fungus threatening global wheat production. The research suggests that the right set of conditions could lead to significant crop losses in some parts of the world.
Scientists report significant progress in developing new wheat varieties resistant to virulent stem rust Ug99, which threatens global wheat production. The mutated fungus is on the march towards South Asia, where poor subsistence growers produce a significant portion of the world's wheat.
A broad-based global partnership will focus on developing improved rust-resistant wheat varieties to protect resource-poor farmers and consumers from catastrophic crop losses in vulnerable regions, particularly India and Africa. The project aims to combat the emergence of deadly new variants of stem rust that can spread quickly.
