Pathogen anatomy and disease cycle Xylella fastidiosa is rod-shaped, and at least one subspecies has two types of pili on only one pole; longer, type IV pili are used for locomotion, while shorter, type I pili assist in biofilm formation inside their hosts.

Leaf scorch. As in plum trees, other trees show scalded leaves, including oak, sycamore, elm, and maple. Pierce’s disease. Affecting grapevines, Pierce’s disease causes delayed leaf production, stunted shoots, mottling, chlorosis, and scalding on leaves, premature fruit, and ultimately loss of vigor and death. Citrus variegated chlorosis. Det är viktigt att vi
Introduction. Xylella fastidiosa is a gram-negative, xylem-limited, and slow-growing bacterium transmitted by some xylem-feeding vectors (Wells et al., ), and it is the causal agent of several plant diseases (Hopkins and Purcell, ).

Xylella fastidiosa is a vector -transmitted bacterial plant pathogen associated with serious diseases in a wide range of plants. It causes Pierce’s disease in grapevine, which is a major problem for wine producers in the United States and South America. X. Det kan till exempel vara
Go to: Xylella fastidiosa has a unique association with its xylem sap–feeding insect vectors X. fastidiosa is obligately vectored by xylem-feeding hemipteran insects primarily belonging to the sharpshooter leafhopper (Cicadellidae) and spittlebug (Cercopidae) families (Fig 1) [ 9 – 11 ].

Host Plants in Europe. Bacterium X. fastidiosa is a polyphagous pathogen that attacks a wide range of host plants, from weeds and ornamental plants and shrubs to economically very important fruit-growing, woody and forest plants (Girelli et al., ; Godefroid et al., ). Currently, the list of host plants maintained by EFSA includes

Xylella fastidiosa. A bacterium that lives in the water conducting system (xylem) of plants. Grapevines show symptoms of water stress, such as leaf scorch, and the plant progressively weakens and dies. Can be transmitted in infected propagation material and by leafhoppers such as the exotic glassy-winged sharpshooter. Tyvärr finns det ingen behandling
Xylella fastidiosa is a Gram-negative, rod-shaped bacterium with dimensions of to µm in radius and to µm in length (6). It has distinctive rippled cell walls, and possesses two types of polar pili: type I pili to µm in length, and type IV pili 1 to 6 µm in length (6). Both types of pili are positioned at the same.
