Adherence and motility characteristics of clinical Acinetobacter baumannii isolates

Acinetobacter baumannii continues to be a major health problem especially in hospital settings. Herein, features that may play a role in persistence and disease potential were investigated in a col...

A new regulatory DNA motif of the gamma subclass proteobacteria: identification of the LexA protein binding site of the plant pathogen Xylella fastidiiosa

Escherichia coli LexA protein is the repressor of a gene network whose members are directly involved in the repair of damaged DNA and in the survival of bacterial cells until DNA lesions have been ...

Bacterial variations on the methionine salvage pathway

The thiomethyl group of S-adenosylmethionine is often recycled as methionine from methylthioadenosine. The corresponding pathway has been unravelled in Bacillus subtilis. However methylthioadenosin...

BigR is a sulfide sensor that regulates a sulfur transferase/dioxygenase required for aerobic respiration of plant bacteria under sulfide stress

To cope with toxic levels of H2S, the plant pathogens Xylella fastidiosa and Agrobacterium tumefaciens employ the bigR operon to oxidize H2S into sulfite. The bigR operon is regulated by the transc...

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 plastid-related gene profiling based on expressed sequence tag analyses

Plastid-related sequences, derived from putative nuclear or plastome genes, were searched in a large collection of expressed sequence tags (ESTs) and genomic sequences from the Citrus Biotechnology...

Comparative analysis of differentially expressed sequence tags of sweet orange and mandarin infected with Xylella fastidiosa

The Citrus ESTs Sequencing Project (CitEST) conducted at Centro APTA Citros Sylvio Moreira/IAC has identified and catalogued ESTs representing a set of citrus genes expressed under relevant stress ...

Fast Detection of Olive Trees Affected by Xylella Fastidiosa from UAVs Using Multispectral Imaging

Xylella fastidiosa(Xf) is a well-known bacterial plant pathogen mainly transmitted by vector insects and is associated with serious diseases affecting a wide variety of plants, both wild and cult...

Functional analysis of Xylella fastidiosa PD0576 gene encoding a histidine kinase and response regulator hybrid protein

Xylella fastidiosa (Xf), a xylem-limited insect-vectored pathogenic bacterium, is the causative agent of devastating plant diseases in many economically important crops in the Americas, Europe and ...

Global gene expression under nitrogen starvation in Xylella fastidiosa: contribution of the sigma(54) regulon

Xylella fastidiosa, a Gram-negative fastidious bacterium, grows in the xylem of several plants causing diseases such as citrus variegated chlorosis. As the xylem sap contains low concentrations of ...

Identification and analysis of seven effector protein families with different adaptive and evolutionary histories in plant-associated members of the Xanthomonadaceae

The Xanthomonadaceae family consists of species of non-pathogenic and pathogenic gamma-proteobacteria that infect different hosts, including humans and plants. In this study, we performed a compara...

Identification and in silico analysis of the Citrus HSP70 molecular chaperone gene family

The completion of the genome sequencing of the Arabidopsis thaliana model system provided a powerful molecular tool for comparative analysis of gene families present in the genome of economically r...
