Dr. John Bedbrook of DiCE Molecules LLC spoke at KAUST about the challenges of feeding a growing population with increasingly stressed arable land. He noted the increasing demand for meat in emerging economies exacerbates the problem. Bedbrook emphasized the role of genetics and hybridization in improving crop yields and quality to address food security. Why it matters: Investments in agricultural biotechnology are crucial for the GCC region to enhance food security and reduce reliance on imports amid changing climate conditions.
KAUST researchers are working to improve gene editing tools, specifically CRISPR/Cas9, for crop bioengineering to address food security challenges. Magdy Mahfouz's lab is developing a germline engineering platform to produce gene-edited plants without foreign DNA and bypass time-consuming tissue culture. A recent European court decision classifies CRISPR/Cas9 crops as GMOs, facing stringent regulations, contrasting with the U.S. where CRISPR-edited mushrooms are already available. Why it matters: Advances in gene editing at KAUST could significantly enhance crop yields and stress tolerance in the region, but regulatory hurdles remain a key challenge for deployment.
Dr. Ingo Potrykus, co-inventor of Golden Rice, discussed the potential of this genetically modified crop to combat vitamin A deficiency at KAUST's 2014 Winter Enrichment Program. Golden Rice, engineered to produce beta carotene, could prevent millions of deaths and cases of blindness annually in developing countries where rice is a staple. Regulatory hurdles for GMOs have stalled the distribution of Golden Rice, increasing development costs and delaying its availability to farmers. Why it matters: This highlights the potential of biotechnology developed and discussed in the GCC to address global health challenges, but also the regulatory and ethical considerations surrounding GMOs.
KAUST research scientist Dr. Maged Saad is working on unconventional methods for global food security within the Desert Agriculture Initiative. His research involves using selected strains of bacteria to increase salt tolerance and crop productivity in desert plants. Dr. Saad aims to convert this technology into a marketable product by securing intellectual property rights, testing prototypes with Saudi farmers, and establishing a startup. Why it matters: This research aligns with Saudi Arabia's Vision 2030 goals to enhance local agricultural production and promote sustainable solutions for food security in arid environments.
KAUST Associate Professor Liming Xiong is researching how plants adapt to drought conditions, focusing on reducing water consumption, increasing water uptake, and surviving under stress. His "whole plant" approach aims to identify major genes controlling water uptake, water loss, and cellular detoxification. The research seeks to develop plants that use water more efficiently or can be irrigated with brackish water, important for agriculture in Saudi Arabia. Why it matters: Understanding the molecular mechanisms of plant drought tolerance can help in breeding stress-tolerant crops suitable for the arid conditions in the region.
KAUST's Center of Excellence for Sustainable Food Security (CoE-SFS) has launched 12 translation projects focused on plant growth and water security, establishing partnerships with public and private entities to scale up research. Mark Tester's team developed stress-tolerant rootstocks, grafted onto crops like tomatoes, that thrive in hot, dry conditions with increased yields. Through his start-up Iyris, Tester is conducting commercial field trials in over 12 countries. Why it matters: These efforts to adapt agriculture to environmental change are crucial for ensuring food security in Saudi Arabia, the region, and globally, especially in the face of climate change and limited water resources.
KAUST's Center for Desert Agriculture is holding an international conference on November 3-5, 2014, focusing on desert rhizosphere microbes for sustainable agriculture. Researchers aim to understand how plants survive in extreme conditions by studying microbes that help them tolerate heat, drought, and salt. They will explore genetic engineering and natural microbe usage to improve crop performance under heightened stress conditions. Why it matters: This research is critical for adapting agricultural systems to global warming and meeting future food production challenges in arid regions like the Middle East.
KAUST researchers collaborated to identify molecular pathways for plant biofortification of vitamin A. A KAUST group demonstrated high pressure conversion of carbon dioxide into useful products. Another team designed a biosensor using metal oxide transistors to detect glucose in saliva. Why it matters: These projects highlight KAUST's contributions to biotechnology, environmental sustainability, and healthcare through advanced materials and molecular techniques.
