Xanthomonas Campestris Pv. Vitians
''Xanthomonas'' (from greek: ''xanthos'' – "yellow"; ''monas'' – "entity") is a genus of bacteria, many of which cause plant diseases. There are at least 27 plant associated ''Xanthomonas spp.'', that all together infect at least 400 plant species. Different species typically have specific host and/or tissue range and colonization strategies. Taxonomy The genus ''Xanthomonas'' has been subject of numerous taxonomic and phylogenetic studies and was first described as ''Bacterium vesicatorium'' as a pathogen of pepper and tomato in 1921. Dowson later reclassified the bacterium as ''Xanthomonas campestris'' and proposed the genus ''Xanthomonas''.''Xanthomonas'' was first described as a monotypic genus and further research resulted in the division into two groups, A and B. Later work using DNA:DNA hybridization has served as a framework for the general ''Xanthomonas'' species classification. Other tools, including multilocus sequence analysis and amplified fragment-length polymorp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Xanthomonas Perforans
''Xanthomonas perforans'' is a species of bacteria. It is a parasite of plants including pepper and tomatoes, causing spots on infected leaves and fruit. ''X. perforans'' shows most growth at temperatures of 25-30C. It is widespread, but mostly found in North and South America. It was shown to be insufficiently different from '' Xanthomonas euvesicatoria'' to be its own species in 2016. As a result it became ''Xanthomonas euvesicatoria'' pv. ''perforans''. (Note: pathovars are not governed by the ''Prokaryotic Code The International Code of Nomenclature of Prokaryotes (ICNP) or Prokaryotic Code, formerly the International Code of Nomenclature of Bacteria (ICNB) or Bacteriological Code (BC), governs the scientific names for Bacteria and Archaea.P.

Xanthomonas Oryzae
''Xanthomonas oryzae'' is a species of bacteria. The major host of the bacterium is rice. The species contains two pathovars, neither of which is native to Europe: ''X. o.'' pv. ''oryzae'' and ''X. o.'' pv. ''oryzicola''. ''Xanthomonas oryzae'' epidemics can cause yield losses ranging from 2-74%, and the bacteria can be carried on rice seeds, causing further disease spread. The host resistance gene, '' Xa21'', from '' Oryza longistaminata'', is integrated into the genome of ''Oryza sativa ''Oryza sativa'', having the common name Asian cultivated rice, is the much more common of the two rice species cultivated as a cereal, the other species being ''Oryza glaberrima, O. glaberrima'', African rice. It was History of rice cultivation ...'' for its broad-range resistance to rice leaf blight caused by ''X. o.'' pv. ''oryzae''.

Xanthomonas Maltophila
'' Stenotrophomonas maltophilia'' is an aerobic, nonfermentative, Gram-negative bacterium. It is an uncommon bacterium and human infection is difficult to treat. Initially classified as ''Bacterium bookeri'', then renamed ''Pseudomonas maltophilia'', ''S. maltophilia'' was also grouped in the genus ''Xanthomonas'' before eventually becoming the type species of the genus '' Stenotrophomonas'' in 1993. ''S. maltophilia'' is slightly smaller (0.7–1.8 × 0.4–0.7 μm) than other members of the genus. They are motile due to polar flagella, and grow well on MacConkey agar producing pigmented colonies. ''S. maltophilia'' is catalase-positive, oxidase-negative (which distinguishes it from most other members of the genus) and has a positive reaction for extracellular DNase. ''S. maltophilia'' is ubiquitous in aqueous environments, soil, and plants; it has also been used in biotechnology applications. In immunocompromised patients, ''S. maltophilia'' can lead to nosocomia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xanthomonas Malvacearum
Bacterial blight of cotton is a disease affecting the cotton plant resulting from infection by ''Xanthomonas citri, Xanthomonas axonopodis pathovar malvacearum'' (Xcm) a Gram negative, motile rod-shaped, non spore-forming bacterium with a single polar flagellum __TOC__ Symptoms The bacterium, bacteria can affect the cotton plant during all growth stages, infecting stems, leaves, bracts and bolls. It causes seedling blight, leaf spot, blackarm (on stem and petioles), black vein and boll rot. On cotyledons small, green, water-soaked rounded (or irregular) spots form which turn brown. Cotyledons can be distorted if the infection is intense. Black and elongated lesions can girdle the hypocotyls and kill seedlings. On the leaves, scattered small dark-green, water-soaked, areolate spots, form measuring 1–2 mm on the lower surface, which appear translucent against transmitted light. The spots increase in diameter to 5 mm, become angular (due to leaf veination), brown and l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
