Xanthomonas campestris pv. (Xcc) is a harmful pathogen of the Brassicaceae agricultural plants in Serbian agroecological conditions. The bacterium survives soil, plant residues, seeds, and wild weedy plants. This study aimed to characterize Xcc isolates that persist field soil roots where they represent risk causing disease Collection samples was carried out period 2015 - 2017 four locations re...
We report high-quality draft genome sequences of two strains (race 18 and 20) of Xanthomonas citri pv. malvacearum, the causal agent of bacterial blight of cotton. Comparative genomics will help to decipher mechanisms provoking disease and triggering defense responses and to develop new molecular tools for epidemiological surveillance.
Many Xanthomonas bacteria use transcription activator-like effector (TALE) proteins to activate plant disease susceptibility (S) genes, and this activation contributes to disease. We recently reported that rice basal transcription factor IIA gamma subunit, OsTFIIAγ5, is hijacked by TALE-carrying Xanthomonas oryzae infecting the plants. However, whether TFIIAγs are also involved in TALE-carrying...
Many gram-negative plant and animal pathogenic bacteria employ a type III secretion system (T3SS) to subvert and colonize their respective host organisms. The T3SS injects effector proteins directly into the cytosol of eukaryotic cells and thus allows the manipulation of host cellular activities to the benefit of the pathogen. In plant pathogenic bacteria, T3SSs are encoded by hrp (for hypersen...
Bacterial spot disease of pepper and tomato is caused by four distinct Xanthomonas species and is a severely limiting factor on fruit yield in these crops. The genetic diversity and the type III effector repertoires of a large sampling of field strains for this disease have yet to be explored on a genomic scale, limiting our understanding of pathogen evolution in an agricultural setting. Genome...
Black rot, caused by Xanthomonas campestris pv. campestris (Xcc), is a severe seedborne disease of Brassica crops around the world. Nine races are recognized, being races 1 and 4 the most aggressive and widespread. The identification of Xcc races affecting Brassica crops in a target area is necessary to establish the adequate control measures and breeding strategies. The objectives of this stud...
Isoelectric focusing (IEF) profiles of pectate lyases (PLs) produced by five different groups of soft rot bacteria were analyzed by using the combined techniques of thin-layer polyacrylamide gel IEF and agarose-pectate overlay activity staining. Four strains of soft rot Erwinia spp. produced three or more PL isozymes. All of eight Pseudomonas viridiflava strains examined produced one single PL ...

Xanthomonas bacterium exhibited post-exponential programmed cell death (PCD) under certain nutritional conditions especially in a protein rich medium. PCD was not displayed by Xanthomonas cells while growing in minimal medium like starch minimal medium or M9 medium. While undergoing PCD, the organism was found to transform to spherical membranous apoptotic body like structures. The transformati...
We present here the draft genome sequences of bacterial pathogens of the Araceae family, Xanthomonas axonopodis pv. dieffenbachiae LMG 695 and Xanthomonas campestris pv. syngonii LMG 9055, differing in host range. A comparison between genome sequences will help understand the mechanisms involved in tissue specificity and adaptation to host plants.
