A cell-cell signaling sensor is required for virulence and insect transmission of Xylella fastidiosa
Cell-cell signaling in Xylella fastidiosa, a xylem-colonizing plant pathogenic bacterium, mediated by a fatty acid Diffusible Signaling Factor (DSF), is required to colonize insect vectors and to s...
A chitinase is required for Xylella fastidiosa colonization of its insect and plant hosts
Xylella fastidiosa colonizes the xylem network of host plant species as well as the foregut of its required insect vectors to ensure efficient propagation. Disease management strategies remain inef...
Advances and innovative concepts to control Xylella fastidiosa colonization in citrus plants
Xylella fastidiosa is responsible for diseases that affect different crops worldwide. One of them is Citrus Variegated Chlorosis (CVC), which results from the xylem vessels occlusion by X. fastidio...
Analysis of 16S rRNA and mxaF genes revealing insights into Methylobacterium niche-specific plant association
The genus Methylobacterium comprises pink-pigmented facultative methylotrophic (PPFM) bacteria, known to be an important plant-associated bacterial group. Species of this group, described as plant-...
Anterior Foregut Microbiota of the Glassy-Winged Sharpshooter Explored Using Deep 16S rRNA Gene Sequencing from Individual Insects
The glassy-winged sharpshooter (GWSS) is an invasive insect species that transmits Xylella fastidiosa, the bacterium causing Pierce's disease of grapevine and other leaf scorch diseases. X. fastidi...
Assessing adhesion, biofilm formation and motility of Acidovorax citrulli using microfluidic flow chambers
Acidovorax citrulli is the causal agent of bacterial fruit blotch of cucurbits. We have shown previously that type IV pili (TFP) are required for wild-type levels of virulence of A. citrulli on mel...
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...
Calcium-Enhanced Twitching Motility in Xylella fastidiosa Is Linked to a Single PilY1 Homolog
The plant-pathogenic bacterium Xylella fastidiosa is restricted to the xylem vessel environment, where mineral nutrients are transported through the plant host; therefore, changes in the concentrat...
Cassava endophytic microorganisms of commercial plantings and ethnovarieties in three Brazilian states
The aim of this work was to perform a survey of the diversity of endophytic microorganisms in cassava (Manihot esculenta Crantz) collected from commercial plantings, in the State of Sao Paulo, and ...
Cell-cell signaling controls Xylella fastidiosa interactions with both insects and plants
Xylella fastidiosa, which causes Pierce's disease of grapevine and other important plant diseases, is a xylem-limited bacterium that depends on insect vectors for transmission. Although many studie...
Chitin Utilization by the Insect-Transmitted Bacterium Xylella fastidiosa
Xylella fastidiosa is an insect-borne bacterium that colonizes xylem vessels of a large number of host plants, including several crops of economic importance. Chitin is a polysaccharide present in ...
Citrus sinensis LEAF PETIOLE AND BLADE COLONIZATION BY Xylella fastidiosa: DETAILS OF XYLEM VESSEL OCCLUSION
Citrus variegated chlorosis (CVC), caused by Xylella fastidiosa, is an important disease of citrus in Brazil. X. fastidiosa is restricted to xylem vessels of plants and knowledge regarding xylem co...
