CFPB 1694

Pathovars

'Pseudomonas helianthi' is a Gram-negative plant pathogenic bacterium that infects a variety of plants. It was once considered a pathovar of Pseudomonas syringae, but following DNA-relatedness studies, it was recognized as a separate species and P. syringae pv. tagetis was incorporated into it, as well^[1]. Since no official name has yet been given, it is referred to by the epithet 'Pseudomonas helianthi' ^[2].

[edit] Pathovars

'Pseudomonas helianthi' pv. helianthi attacks sunflowers (Helianthus annuus).

'Pseudomonas helianthi' pv. tagetis attacks marigolds (Tagetes erecta).
