Pantoea agglomerans is the etiological agent for black spot necrosis on beach peas
Pantoea agglomerans was isolated from necrotic spots in the leaves of a beach pea (Lathyrus maritimus L.) that grew on the shorelines of Newfoundland, Canada. The bacterium produced cellulase and amylase and was shown to be a wound parasite. Ultrastructural studies of infected leaves showed bacteria...
