Technical Abstract: Bacterial stem blight (BSB) of alfalfa (Medicago sativa) is a disease characterized by necrotic lesions on stems, chlorosis and necrosis of leaves, and wilt resulting in curled shoot tips resembling a shepherd’s crook, and is associated with ice nucleation active bacteria in the Pseudomonas syringae species complex. Strains grouping with Pseudomonas syringae phylogroup 2b (PG2b) and Pseudomonas viridiflava phylogroup 7a (PG7a) based on citrate synthetase (cts) sequences have been attributed to cause BSB. Here, the genomes of 12 PG2b and eight PG7a strains isolated from alfalfa with symptoms of BSB were sequenced with Illumina NextSeq 550 and Oxford Nanopore Technology (ONT) Minion and were annotated with the NCBI Prokaryotic Genome Annotation Pipeline. These genome sequences will be valuable for further BSB research and may have applications in the development of BSB-resistant alfalfa plants.
