During the last 20 years, the causative agents of bacterial spot of tomato and pepper have been subjected to many studies and reclassifications. According to the current data, the species are four (X. euvesicatoria, X. vesicatoria, X. gardneri, and X. perforans) and cause similar symptoms in plants but possess different phenotypic properties. This work provides the full metabolic characteristic...

The gram-negative plant-pathogenic bacterium Xanthomonas campestris pv. vesicatoria is the causative agent of bacterial spot disease in pepper and tomato plants, which leads to economically important yield losses. This pathosystem has become a well-established model for studying bacterial infection strategies. Here, we present the whole-genome sequence of the pepper-pathogenic Xanthomonas campe...

We report here the complete 4.7-Mb genome sequence of Xanthomonas translucens pv. translucens DSM 18974T, which causes black chaff disease on barley (Hordeum vulgare). Genome data of this X. translucens type strain will improve our understanding of this bacterial species.

Xanthomonas arboricola pv. pruni is the causal agent of bacterial spot disease of stone fruits, a quarantinable pathogen in several areas worldwide, including the European Union. In order to develop efficient control methods for this disease, it is necessary to improve the understanding of the key determinants associated with host restriction, colonization and the development of pathogenesis. A...

Phytopathogenic bacteria represent a risk to global food production by impacting variety of crops. The aim this study was characterize the contents bioactive constituents in extracts from Ginkgo biloba L. leaves and fruits test their activity against six phytopathogenic that affect horticultural Gas chromatography–mass spectrometry (GC−MS) used for chemical profiling aqueous methanol extracts, ...

Xanthomonas citri subsp citri (Xac) is the bacterium responsible for citrus canker disease in citrus plants. The aim of this study was to describe the recombinant expression, purification, and characterization of a cysteine peptidase from Xac strain 306, which is a candidate for involvement in the pathogenicity of this bacterium. The gene was cloned and expressed in Pichia pastoris, and the cys...

We report the draft genome sequence of the Xanthomonas cassavae type strain CFBP 4642, the causal agent of bacterial necrosis on cassava plants. These data will allow the comparison of this nonvascular pathogen with the vascular pathogen Xanthomonas axonopodis pv. manihotis, both infecting the same host, which will facilitate the development of diagnostic tools.

The phyllosphere supports a tremendous diversity of microbes and other organisms. However, little is known about the colonization and survival of pathogenic and beneficial bacteria alone or together in the phyllosphere across the whole plant life-cycle under herbivory, which hinders our ability to understand the role of phyllosphere bacteria on plant performance. We addressed these questions in...
