KAUST and the International Maize and Wheat Improvement Center (CIMMYT) have signed an MoU to collaborate on developing climate-resilient food crops. The collaboration will combine CIMMYT’s expertise in maize and wheat breeding with KAUST’s strengths in genomics and computational agriculture. The partnership will focus on genomic selection, data analytics, and digital breeding technologies, including capacity-building programs. Why it matters: The partnership aims to enhance food security in Saudi Arabia and the wider region by developing resilient, high-yielding crop varieties suited to arid environments.
KAUST researchers have discovered the first molecular events that trigger wheat's immunity to stem rust, a devastating fungal disease. The study, published in Science, identifies that tandem kinases are bound together and inactive until a pathogen binds, initiating an immune response that kills the infected cell. This prevents the pathogen from spreading and causing widespread crop damage. Why it matters: Understanding these molecular mechanisms could lead to engineering wheat with stronger and more durable resistance to stem rust and other diseases, safeguarding a crucial food source in the face of climate change and emerging pathogens.
KAUST researchers have developed a genomic resource for Tausch’s goatgrass (Aegilops tauschii), a wild relative of wheat, by creating 46 high-quality genome assemblies. They compiled 493 genetically distinct accessions from an initial 900, collaborating with the Open Wild Wheat Consortium to select accessions with traits of interest, such as disease resistance and stress tolerance. Screening these assemblies helped identify rust resistance genes, including mapping a stem rust resistance gene to the Sr33 locus. Why it matters: This genomic resource will accelerate gene discovery in wheat, potentially improving modern wheat varieties and enhancing global food security.
Hanin Ahmed, a KAUST Ph.D. graduate in plant science, is now an Ibn-Rushd Postdoctoral Fellow at The Centre for Anthropology and Genomics of Toulouse, France. Her Ph.D. research at KAUST focused on the population genomics and evolutionary history of fonio millet and einkorn wheat. One key finding was the influence of ethnic groups on the genetic diversity of fonio millet, and insights into wheat adaptation during early agriculture from einkorn wheat research published in Nature. Why it matters: This highlights KAUST's role in training researchers who are contributing to advancements in genomics and agriculture, with implications for crop improvement and understanding the impact of social factors on plant genetics.
KAUST researchers reported the full genome sequencing of einkorn wheat in Nature. A new 'cooling score' metric was created to study heat's impact on solar cell performance. KAUST is also optimizing MXenes for lithium batteries and using biomimetic mineralization for smart agriculture. Why it matters: This research demonstrates KAUST's contributions to diverse fields, including genomics, sustainable energy, and smart agriculture, advancing technological innovation in Saudi Arabia.
