Comparative proteome analysis of Xanthomonas campestris pv. campestris in the interaction with the susceptible and the resistant cultivars of Brassica oleracea
Black rot of cruciferous plants, caused by Xanthomonas campestris pv. campestris, causes severe losses in agriculture around the world. This disease affects several cultures, including cabbage and ...
Detection of Xylella fastidiosa from resistant and susceptible grapevine by tissue sectioning and membrane entrapment immunofluorescence
Immunofluorescence detection was performed by tissue sectioning and membrane entrapment of Xylella fastidiosa from the inoculated hybrid selection F8909-08 (Vitis rupestris A. de Serres x V. arizon...
Impact of phenolic compounds on progression of Xylella fastidiosa infections in susceptible and PdR1-locus containing resistant grapevines
Pierce's disease is of major concern for grapevine (Vitis vinifera) production wherever the bacterial pathogenXylella fastidiosaand its vectors are present. Long-term management includes the depl...
Inhibition of Xylella fastidiosa polygalacturonase to produce Pierce's disease resistant grapevines
Polygalacturonases (PG) (EC 3.2.1.15), catalyze the random hydrolysis of 1, 4-alpha-D-galactosiduronic linkages in pectate and other galacturonans. Xylella fastidiosa (Xf) possesses a single PG gen...
Ionomic Differences between Susceptible and Resistant Olive Cultivars Infected by Xylella fastidiosa in the Outbreak Area of Salento, Italy
Olive quick decline syndrome (OQDS) is a devastating disease of olive trees in the Salento region, Italy. This disease is caused by the bacterium Xylella fastidiosa, which is widespread in the outb...
ISOLATION AND PRELIMINARY CHARACTERIZATION OF EXTRACELLULAR PROTEASES PRODUCED BY STRAINS OF XYLELLA-FASTIDIOSA FROM GRAPEVINES
Virulent and weakly virulent grape strains of Xylella fastidiosa grew well on PD3 amended with gelatin and produced zones of hydrolysis on this medium, indicating the presence of proteolytic activi...
MULTIPLICATION AND MOVEMENT OF XYLELLA-FASTIDIOSA WITHIN GRAPEVINE AND 4 OTHER PLANTS
Xylella fastidiosa, a xylem-limited bacterium that causes Pierce's disease of grapevine and other plant diseases, has numerous symptomless hosts. The multiplication and spread of X. fastidiosa with...
MULTIPLICATION AND TRANSLOCATION OF XYLELLA-FASTIDIOSA IN PETIOLES AND STEMS OF GRAPEVINE RESISTANT, TOLERANT, AND SUSCEPTIBLE TO PIERCES DISEASE
Petioles of Vitis vinifera ‘French Colombard’ (susceptible to Pierce’s disease), and V. rotundifolia ‘Carlos’ (tolerant) and ‘Noble’ (resistant) were inoculated with virulent strain FC of Xylella f...
Pruning-induced tylose development in stems of current-year shoots of Vitis vinifera (Vitaceae)
Tyloses form in xylem vessels in response to various environmental stimuli, but little is known of the kinetics or regulation of their development. Preliminary investigations indicated that wounds ...
RESPONSE OF RESISTANT, TOLERANT, AND SUSCEPTIBLE GRAPEVINE TISSUES TO INVASION BY THE PIERCES DISEASE BACTERIUM, XYLELLA-FASTIDIOSA
Microtechniques were used to quantify occlusion of leaf veins of grapevines inoculated with Xylella fastidiosa. Bacteria and pectins were responsible for most occlusions in xylem vessels of inocula...
SCS 438 Zafira - a new plum cultivar resistant to leaf scald (Xylella fastidiosa)
‘SCS438 Zafira’ is a novel plum cultivar, adapted to southern Brazil. It produces high-quality fruits, very similar to ‘Fortune’, the standard mid-season cultivar. Its main advantage is the resista...
