Pseudomonas amygdali

Pseudomonas amygdali is a Gram-negative plant pathogenic bacterium.[1] It is named after its ability to cause disease on almond (Prunus amygdalus) trees. Based on 16S rRNA analysis, P. amygdali has been placed in the P. syringae group.[2] Following ribotypical analysis several pathovars of Pseudomonas syringae were incorporated into this species.[3] It was also proposed that Pseudomonas ficuserectae, Pseudomonas meliae, and Pseudomonas savastanoi be incorporated into this species,[3] though there is not a consensus,[2] while others assert that Pseudomonas savastanoi is the more legitimate name.[4]
