Bacterial leaf spot caused by Xanthomonas was reported in 2014 as a new disease of crape myrtle. Unfortunately, this foundational strain was lost, preventing further experimentation, sequencing of the genome, and phylogenetic analysis. This work describes a collection of Xanthomonas strains isolated from angular leaf spot lesions on crape myrtle in North Carolina from 2014 to 2023.

- In July 2022, lesions indicative of bacterial leaf spot (BLS) were observed on various sesame plant varieties in North Carolina, with certain varieties showing up to 75% disease prevalence.
- Leaf samples from affected plants were collected and cultured on specialized media, resulting in the isolation of colonies that were then genotyped to identify their genetic makeup.
- Phylogenetic analysis confirmed that the isolates were Pseudomonas syringae pv. sesami, linking the observed symptoms to this specific bacterial pathovar.
