Here, we describe the draft genome sequences of two Xylella fastidiosa strains: Xf6c and Xf32, which have been obtained from infected coffee plants in Brazil, and are associated with the disease known as coffee leaf scorch (CLS).
Xylella fastidiosa infects a wide range of plant hosts and causes economically serious diseases, including Pierce's disease (PD) of grapevines. X. fastidiosa biocontrol strain EB92-1 is infectious to grapevines but does not cause symptoms. The draft genome of EB92-1 reveals that it may be missing 10 potential pathogenicity effectors.
Xylella fastidiosa (Xf) causes wilt disease in plants and is responsible for major economic and crop losses globally. Owing to the public importance of this phytopathogen we embarked on a comparative analysis of the complete genome of Xf pv citrus and the partial genomes of two recently sequenced strains of this species: Xf pv almond and Xf pv oleander, which cause leaf scorch in almond and ole...
Incompatibility group P1 (IncP-1) plasmid diversity was evaluated based on replication initiator protein (TrfA) phylogeny. A new and highly divergent clade was identified. Replication assays indicated that TrfA of recently discovered IncP-1 plasmids from Xylella fastidiosa and Verminephrobacter eiseniae initiated plasmid replication using cognate or heterologous origins of replication.
The draft genome sequence of Xylella fastidiosa CO33 isolate, retrieved from symptomatic leaves of coffee plant intercepted in northern Italy, is reported. The CO33 genome size is 2,681,926 bp with a GC content of 51.7%.
INTRODUCTION One of our projects involved the development of a transformation and transposon mutagenesis systems for the bacterium that causes Pierce's disease (PD), Xylella fastidiosa (Xf). We now have a random transposon mutagenesis system working for Xf (Guilhabert, et al. 2001) and recently we have developed an E. coli/Xf plasmid shuttle vector. We are currently assessing the stability of t...
The Ohr (organic hydroperoxide resistance) family of 15-kDa Cys-based, thiol-dependent peroxidases is central to the bacterial response to stress induced by organic hydroperoxides but not by hydrogen peroxide. Ohr has a unique three-dimensional structure and requires dithiols, but not monothiols, to support its activity. However, the physiological reducing system of Ohr has not yet been identif...
Pierce's Disease (PD) of grapevines, caused by Xylella fastidiosa subsp. fastidiosa (Xf), is a limiting factor in the cultivation of grapevines in the US. There are presently no effective control methods to prevent or treat PD. The therapeutic and prophylactic efficacy of a phage cocktail composed of four virulent (lytic) phages was evaluated for control of PD. Xf levels in grapevines were sign...
This study reports a de novo-assembled draft genome sequence of Xylella fastidiosa subsp. multiplex strain BB01 causing blueberry bacterial leaf scorch in Georgia, USA. The BB01 genome is 2,517,579 bp, with a G+C content of 51.8%, 2,943 open reading frames (ORFs), and 48 RNA genes.
