The 5th Annual Bacterial Leaf Streak (BLS) Research Initiative Conference, held March 30–April 1, 2026 at South Dakota State University in Brookings, brought together researchers, students, and industry professionals for a dynamic and engaging exchange of ideas. The event focused on advancing our understanding of bacterial leaf streak in cereal crops and developing practical solutions for its management.
Across three days, participants explored cutting-edge research on disease resistance, pathogen biology, and innovative management strategies. From insightful plenary talks to interactive discussions, the conference highlighted the global importance of BLS and the need for collaborative, science-driven approaches.
A major highlight was the strong presence of students, who shared their work through oral presentation, lightning talks, and poster sessions. Their contributions showcased fresh perspectives and emerging research shaping the future of plant pathology.
Beyond the sessions, the conference fostered meaningful connections through networking events, working group discussions, and collaborative planning activities. These interactions helped strengthen ongoing efforts to address BLS challenges across regions and disciplines.
Overall, the conference was a vibrant and productive gathering that reinforced the importance of collaboration, innovation, and continued research in tackling bacterial leaf streak and supporting sustainable crop production.
We look forward to continuing this momentum at the next meeting!

Bacterial Leaf Streak
Bacterial leaf streak (BLS) is an increasingly important disease of cereals caused by the bacterial pathogen Xanthomonas translucens. The disease is characterized by an initial water-soaked streaks that turn to chlorotic/necrotic lesions reducing photosynthetic capacity and potentially impacting yield and grain quality.
BLS is difficult to manage due to limited sources of resistance in cultivated barley, variation among pathogen populations, and strong environmental influences on disease development. Addressing these challenges requires a deeper understanding of both the pathogen and the barley host across diverse growing conditions.
The BLS Research Initiative
The BLS Research Initiative is a collaborative effort focused on advancing research on bacterial leaf streak of cereals. The initiative brings together researchers from multiple disciplines to study pathogen diversity, host resistance, and the biological and environmental factors that influence disease outcomes.
By fostering collaboration, sharing resources, and coordinating research efforts, the initiative aims to accelerate discovery and support the development of effective and sustainable strategies for managing BLS in cereal production systems.
