Complete Genome Sequence Resource for Xanthomonas hortorum Isolated from Greek Oregano

In spring 2019, necrotic leaf spots were detected on Greek oregano (Origanum vulgare var. hirtum) plants in a commercial greenhouse operation. An isolate was recovered from the diseased plants. Partial 16S ribosomal RNA sequencing and multilocus sequence analysis revealed that the isolate was a Xanthomonas sp. but proved insufficient to identify the species with certainty. Therefore, whole-genome sequencing using both Nanopore and Illumina technologies was performed. Here, we report the complete and annotated genome sequence of Xanthomonas hortorum strain 108, which was originally isolated from Greek oregano in Long Island, NY, U.S.A.
