Plant Disease Plant Disease First Report of Xanthomonas hortorum pv. hederae Causing Bacterial Leaf Spot of Hedera hibernica in Slovenia M. Pirc, T. Dreo, M. Šuštaršič, J. Erjavec, and M. Ravnikar, National Institute of Biology, Department of Biotechnology and Systems Biology, Večna potSI Ljubljana, Slovenia.

Tiny water-soaked spots appeared on leaves, and these later became necrotic brown spots. These spots consistently yielded yellow slimy colonies of rod-shaped bacteria. Based on the results of biochemical and pathogenicity tests, the pathogen was identified as X. campestris pv. hederae [X.

They proposed that type B strains be renamed Xanthomonas hortorum pv.

vitians. Furthermore, it was proposed that the X. campestris pv. vitlans type A strain be renamed Xanthomonas axonopodis pv. vitians. This was proposed because of high homology with Group 9 strains which, include 34 X. campestris pathovars andX. All the strains used in this study and their related information are listed in Table collection consists of 55 strains of X.

campestris s including the pathotype strain, the type, pathotype or representative strains of the four pathovars of X. hortorum (onii, hederae, carotae and taraxaci), four strains of X. cynarae including the type strain and the pathotype strain.

Bacterial Blight (Xanthomonas hortorum Pv. pelargonii; Formerly, Xanthomonas campestris Pv. pelargonii) Geographic occurrence and impact. At one time, this was the most serious disease of Pelargonium worldwide. The pathogen is spread in Pelargonium production and throughout the world wherever infected stock plants or cuttings are shipped.

Welcome to the Xanthomonas resource!. The genus Xanthomonas in the gamma subdivision of the Proteobacteria consists of 27 plant-associated species, many of which cause important diseases of crops and ornamentals.

Individual species comprise multiple pathogenic variants (pathovars, pv.). Collectively, members of the genus cause disease on at least monocot species and dicot species. Joana G.

Xanthomonas hortorum pv. hederae (Arnaud ) Vauterin, Hoste, Kersters & Swings = Xanthomonas campestris pv. hederae (Arnaud ) Dye b. ICMP ; LMG ; NCPPB Vauterin et al. () chose the pathotype strain of X.

hortorum pv. hederae as the type strain of the species. If this causes uncertainty, then it may be necessary to.

A comprehensive DNA-DNA hybridization study was performed using strains of the genus Xanthomonas. This genus was shown to comprise 20 DNA homology groups which are considered genomic species. Four groups corresponded to the previously described species Xanthomonas albilineans, Xanthomonas fragariae, Xanthomonas oryzae and Xanthomonas populi.

PM Distribution of Xanthomonas hortorum e in Commercial Carrot Seed Lots Jeremiah Dung, Central Oregon Agricultural Research Center, Oregon State University, NW Dogwood Lane, Madras, Oregon Bulk samples of carrot seed are tested for Xanthomonas hortorum e (Xhc) using a seed wash dilution plating assay.

Plant pathogenic bacteria of the genus Xanthomonas cause a variety of diseases in economically important monocotyledonous and dicotyledonous crop plants worldwide. Successful infection and bacterial multiplication in the host tissue often depend on the virulence factors secreted including adhesins, polysaccharides, LPS and degradative enzymes.

du Toit Xanthomonas hortorum pv. carotae causes bacterial blight of carrot and is readily seedborne. Genetic resistance is limited in commercial cultivars, and there has been little public. Mulberry bacterial blight also known as mulberry rotten head disease, caused by Pseudomonas syringae pv.

mori, is a serious common disease worldwide on Morus alba L. (Young et al., (Young et. Keep on the lookout for additional Xanthomonas victims. These diseases are moved within the crop during transplanting or other handling and when bacteria are splashed from one place to another by irrigation or rainfall.

English ivy with haloed bacterial leaf spots caused by X. hortorum pv. hederae. World distribution of Xanthomonas hortorum pv. carotae (XANTCR). Xanthomonas hortorumpv. carotae(Xhc) is an economically important pathogen of carrots. Its ability to epiphytically colonize foliar surfaces and infect seeds can result in bacterial blight of carrots when grown in warm and humid regions.

We used high‐throughput sequencing to determine the genome sequence of isolate M of Xhc. Bacterial blight of carrot (Daucus carota) is caused by Xanthomonas hortorum e (4).

The pathogen is seed transmitted and carrot seeds can be an important source of primary inoculum (2). A outbreak of a disease resembling bacterial blight was observed in Mauritius in 10 ha of carrot crops, primarily in humid areas of the island, at an estimated incidence of 10%.

Xanthomonas hortorum onii (Xhp), the causal agent of bacterial blight in pelargonium, is the most threatening bacterial disease of this ornamental gain an insight into the regulation of virulence in Xhp, we have disrupted the quorum sensing (QS) genes, which mediate the biosynthesis and sensing of the diffusible signal factor (DSF).

Outbreaks of bacterial spot on tomato (BST) caused by Xanthomonas perforans are a major concern for sustainable crop production.

BST is a common occurrence in tomato transplants grown for field production. We hypothesized that BST outbreaks in commercial fields originate from X. perforans strains inadvertently introduced from commercial transplant facilities.
