Interpretive Summary:

Technical Abstract: Bacterial leaf streak (BLS) is a disease of monocot plants characterized by non-vascular inner leaf colonization that leads to water-soaked and then necrotic lesions. Xanthomonas pathogens cause many diseases of monocot and dicot hosts, but only three species lead to BLS. BLS is caused by Xanthomonas translucens on small grains, Xanthomonas vasicola on maize and Xanthomonas oryzae on rice. Each BLS-causing Xanthomonas species has a distinct host range and evolutionary history. Therefore, convergent BLS symptoms are likely driven by similarities in monocot leaf structure and requirements for non-vascular pathogenesis in this space. Here we describe the commonalities across these three evolutionarily distant Xanthomonas species that cause BLS of diverse cropping systems.
