Abstract:

ABSTRACT 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 campestris pv. vesicatoria strain 85-10, which comprises a 5.17-Mb circular chromosome and four plasmids. The genome has a high G+C content (64.75%) and signatures of extensive genome plasticity. Who

Abstract:

Xanthomonas campestris pv. campestris (Xcc) causes the black rot of cruciferous plants. This seed-borne bacterium is considered as the most destructive disease to cruciferous crops. Although sources of contamination are various, seeds are the main source of transmission. Typical symptoms of black rot were first observed in 2011 on cabbage and cauliflower fields in the main production areas of Algeria. Leaf samples displaying typical symptoms were collected during 2011 to 2014, and 170 strains were isolated from 45 commercial fields. Xcc isolates were very homogeneous in morphological, physiolo

Abstract:

Xanthomonads were detected by using the Xan-D(CCF) medium from the brassica seeds, and their pathogenicity was determined by plant inoculation tests. It was found that some seed lots were infested with Xanthomonas campestris pv. campestris, some with X. campestris pv. raphani, and some with nonpathogenic xanthomonads. The nonpathogenic xanthomonad strains were identified as X. campestris, and the multilocus sequence analysis showed that the nonpathogenic X. campestris strains were grouped together with pathogenic X. campestris, but not with nonpathogenic strains of X. arboricola.

The main factor governing transfer in planta appeared to be the frequency of contacts among donors and recipients. The frequency of transfer was correlated with the level of bacterial populations.

However, it is unclear how X. campestris pv. campestris benefits from the metabolic products of the host plant.

Abstract:

Twenty-five Xanthomonas isolates, including some isolates received as either X. campestris pv. armoraciae or pv. raphani, caused discrete leaf spot symptoms when spray-inoculated onto at least one Brassica oleracea cultivar. Twelve of these isolates and four other Xanthomonas isolates were spray- and pin-inoculated onto 21 different plant species/cultivars including horseradish (Armoracia rusticana), radish (Raphanus sativus), and tomato (Lycopersicon esculentum). The remaining 13 leaf spot isolates were spray-inoculated onto a subset of 10 plant species/cultivars. The leaf spot isolates were

Abstract:

Phages of phytopathogenic bacteria are considered to be promising agents for the biological control of bacterial diseases in plants. This paper reports on the isolation and characterisation of a new Xanthomonas campestris pv. campestris phage, Murka. Phage morphology and basic kinetic characteristics of the infection were determined, and a phylogenomic analysis was performed. The phage was able to lyse a reasonably broad range (64%, 9 of the 14 of the Xanthomonas campestris pv. campestris strains used in the study) of circulating strains of the cabbage black rot pathogen. This lytic myovirus h

Abstract:

Coenzyme Q (CoQ) is a lipid-soluble membrane component found in organisms ranging from bacteria to mammals. The biosynthesis of CoQ has been intensively studied in Escherichia coli, where 12 genes (ubiA, -B, -C, -D, -E, -F, -G, -H, -I, -J, -K, and -X) are involved. In this study, we first investigated the putative genes for CoQ8 biosynthesis in the phytopathogen Xanthomonas campestris pv. campestris using a combination of bioinformatic, genetic, and biochemical methods. We showed that Xc_0489 (coq7Xc) encodes a di-iron carboxylate monooxygenase filling the E. coli UbiF role for hydroxylation a

Face às escassas informações acerca da variabilidade patogênica de isolados brasileiros de Xanthomonas campestris pv. campestris, realizou-se um estudo para avaliar a especificidade patogênica de trinta e três isolados do patógeno, provenientes de várias regiões do Brasil e do exterior, a oito espécies de brássicas, através de inoculação por meio de injeção da suspensão bacteriana nas folhas. Desse total, 12 isolados foram obtidos de couve-comum (Brassica oleracea var. acephala), nove de repolho (B. oleracea var. capitata), cinco de couve-flor (B. oleracea var. botrytis), dois de canola (B. na

Abstract:

The effect of temperature on growth of Xanthomonas campestris pv. syngonii isolated from Syngonium podophyllum ‘White Butterfly’ and X. campestris pv. dieffenbachiae isolated from Anthurium andraeanum was tested n vitro. Growth of X. campestris pv. syngonii occurred between 18 (65) and 32°C (90°F) (optimum 26°C [79°C]); growth of X. c. pv. dieffenbachiae occurred from 18 (65) to 34°C (93°F) (optimum 22°C [72°F]). Severity of syngonium blight was greatest for plants maintained at 30°C (86°F); no symptoms developed at temperatures below 26°C (79°F). Preinoculation light levels from 1600 to 5000

Abstract:

Xanthomonas campestris pv. campestris is known as the causative agent of black rot disease, which attacks mainly crucifers, severely lowering their global productivity. One of the main virulence factors of this pathogen is its capability to penetrate and form biofilm structures in the xylem vessels. The discovery of novel approaches to crop disease management is urgent and a possible treatment could be aimed at the eradication of biofilm, although anti-biofilm approaches in agricultural microbiology are still rare. Considering the multifactorial nature of biofilm, an effective approach against
