This pathogen is most likely the same as Pseudomonas syringae pv. coronafaciens. Research by Barta and Willis 2005, examined the relationship between Pseudomonas syringae pvs. coronafaciens, striafaciens, and garcae, showing they are highly similar at a molecular level. While pv. Striafaciens lack the tabtoxin biosynthetic region; their overall physiological traits and pathogenic behaviors are alike, indicating these pathovars may be taxonomically redundant (PSDMST-2).
