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...
Colony aggregation and biofilm formation in xylem chemistry-based media for Xylella fastidiosa
Two chemically defined media based on xylem fluid chemistry were developed for Xylella fastidiosa. These media were tested and compared to chemically defined media XDM2, XDM4 and XF-26. New media w...
Differential expression of genes of Xylella fastidiosa in xylem fluid of citrus and grapevine
Xylella fastidiosa causes a serious Pierce's disease (PD) in grapevine. Xylella fastidiosa cells from a PD strain were grown in a pure xylem fluid of a susceptible grapevine cultivar vs. xylem flui...
EXTRACELLULAR GENOMIC DNA MEDIATES ENHANCEMENT OF XYLELLA FASTIDIOSA BIOFILM FORMATION IN VITRO
Xylella fastidiosa (Xf) produces extracellular DNA in PD3 liquid medium. This extracellular DNA could enhance biofilm formation, a factor in successful establishment of Xf in planta. The relative a...
Grapevine xylem sap enhances biofilm development by Xylella fastidiosa
Xylella fastidiosa is able to form biofilms within xylem vessels of many, economically important crops. Vessel blockage is believed to be a major contributor to disease development caused by this b...
Influence of xylem fluid chemistry on planktonic growth, biofilm formation and aggregation of Xylella fastidiosa
Xylella fastidiosa is the causal agent of Pierce's disease in grapevines. The mechanisms of pathogenicity are largely due to occlusion of xylem vessels by aggregation of X. fastidiosa and biofilm f...
Transcriptome Analysis of the Phytobacterium Xylella fastidiosa Growing under Xylem- Based Chemical Conditions
Xylella fastidiosa is a xylem-limited bacterium responsible for important plant diseases, like citrus-variegated chlorosis (CVC) and grapevine Pierce's disease (PD). Interestingly, in vitro growth ...
