Interpretive Summary:

Technical Abstract: Bacterial leaf blight of rice caused by Pantoea ananatis was first identified in research field plots of global rice germplasm grown in Arkansas, USA in 2021. The disease is characterized by spreading lesions on leaves, panicle sterility and reduced yield. Through comparative analysis of P. ananatis genomes collected in Arkansas with over 150 publicly available genomes, we confirmed the division of P. ananatis into two clades that separated the genomes of rice isolates from those of isolates from other crop species. The Arkansas isolates aligned with the clade comprised of other rice isolates. We are now developing primers specific to rice P. ananatis genomes to enable early detection and diagnosis of this destructive rice pathogen. This research underscores the importance of monitoring emerging plant pathogens and emphasizes the importance of diagnostic measures to help secure global rice production.
