Breaking dogmas: the plant vascular pathogen Xanthomonas albilineans is able to invade non-vascular tissues despite its reduced genome
Xanthomonas albilineans, the causal agent of sugarcane leaf scald, is missing the Hrp type III secretion system that is used by many Gram-negative bacteria to colonize their host. Until now, this p...
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...
Novel Tetraplex Quantitative PCR Assays for Simultaneous Detection and Identification of Xylella fastidiosa Subspecies in Plant Tissues
Xylella fastidiosa (Xf) is an insect-borne bacterium confined to the xylem vessels of plants. This plant pathogen has a broad host range estimated to 560 plant species. Five subspecies of the patho...
Profiling of Disease-Related Metabolites in Grapevine Internode Tissues Infected with Agrobacterium vitis
Green shoot cuttings of 10 different grapevine species were inoculated with Agrobacterium vitis to find disease-related metabolites in the grapevine. Crown galls formed 60 days after inoculation va...
Quantification of Xylella fastidiosa in pecan (Carya Illionoinensis) plant tissues
Pecan Bacterial Leaf Scorch (PBLS) caused by xylem-limited bacterium, Xylella fastidiosa, is a chronic, debilitating disease in species of Carya. PBLS has been recently identified in California, Ar...
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...
