Pseudomonas Syringae
''Pseudomonas syringae'' is a rod-shaped, Gram-negative bacterium with polar flagella. As a plant pathogen, it can infect a wide range of species, and exists as over 50 different pathovars, all of which are available to researchers from international culture collections such as the NCPPB, ICMP, and others. ''Pseudomonas syringae'' is a member of the genus ''Pseudomonas'', and based on 16S rRNA analysis, it has been placed in the ''P. syringae'' group. It is named after the lilac tree (''Syringa vulgaris''), from which it was first isolated. A phylogenomic analysis of 494 complete genomes from the entire ''Pseudomonas'' genus showed that ''P. syringae'' does not form a monophyletic species in the strict sense, but a wider evolutionary group that also included other species as well, such as ''P. avellanae'', ''P. savastanoi'', ''P. amygdali'', and ''P. cerasi''. ''Pseudomonas syringae'' tests negative for arginine dihydrolase and oxidase activity, and forms the polymer levan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chalara Elegans
''Thielaviopsis basicola'' is the plant-pathogen fungus responsible for black root rot disease. This particular disease has a large host range, affecting woody ornamentals, herbaceous ornamentals, agronomic crops, and even vegetable crops. Examples of susceptible hosts include petunia, pansy, poinsettia, tobacco, cotton, carrot, lettuce, tomato, and others. Symptoms of this disease resemble nutrient deficiency but are truly a result of the decaying root systems of plants. Common symptoms include chlorotic lower foliage, yellowing of plant, stunting or wilting, and black lesions along the roots. The lesions along the roots may appear red at first, getting darker and turning black as the disease progresses. Black root lesions that begin in the middle of a root can also spread further along the roots in either direction. Due to the nature of the pathogen, the disease can easily be identified by the black lesions along the roots, especially when compared to healthy roots. The black lesi ...

Sclerotinia Sclerotiorum
''Sclerotinia sclerotiorum'' is a plant pathogenic fungus and can cause a disease called white mold if conditions are conducive. ''S. sclerotiorum'' can also be known as cottony rot, watery soft rot, stem rot, drop, crown rot and blossom blight. A key characteristic of this pathogen is its ability to produce black resting structures known as sclerotia and white fuzzy growths of mycelium on the plant it infects. These sclerotia give rise to a fruiting body in the spring that produces spores in a sac which is why fungi in this class are called sac fungi (Ascomycota). This pathogen can occur on many continents and has a wide host range of plants. When ''S. sclerotiorum'' is onset in the field by favorable environmental conditions, losses can be great and control measures should be considered. Hosts and symptoms ''S. sclerotiorum'' is among the most omnivorous of plant pathogens and so would not make a good mycoherbicide. Economically significant hosts include ''Vicia faba'', for w ...

Uromyces Fabae
''Uromyces viciae-fabae'' var. ''viciae-fabae'' is a plant pathogen commonly known as faba-bean rust. The rust is distinguished by the typical rust-like marks on the stem and leaves, causing defoliation and loss of photosynthetic surface along with reduction in yield. The disease is fungal and is autoecious meaning it has one plant host. The rust of faba beans is macrocyclic, or contains 5 spores during its life cycle. Disease cycle Faba bean rust has a complex lifecycle containing three different stages. Each stage of the cycle has different symptoms. Faba bean rust grows best in July and August as the weather in these months is most fit. The required environment for infection after spores land on a plant consists of rainfall or dew. Also, weather that is humid and warm promotes the spread. Spores can be spread by wind to other plants. An important factor in development of rust epidemics is the infection of volunteer faba bean plants. The disease cycle is as follows: the overwi ...

Thanatephorus Cucumeris
''Rhizoctonia'' is a genus of fungi in the order Cantharellales. Species form thin, effused, corticioid basidiocarps (fruit bodies), but are most frequently found in their sterile, anamorphic state. ''Rhizoctonia'' species are saprotrophic, but some are also facultative plant pathogens, causing commercially important crop diseases. Some are also endomycorrhizal associates of orchids. The genus name was formerly used to accommodate many superficially similar, but unrelated fungi. Taxonomy History Anamorphs ''Rhizoctonia'' was introduced in 1815 by French mycologist Augustin Pyramus de Candolle for anamorphic plant pathogenic fungi that produce both hyphae and sclerotia. The name is derived from Ancient Greek, ῥίζα (''rhiza'', "root") + κτόνος (''ktonos'', "murder"), and de Candolle's original species, ''Rhizoctonia crocorum'' (teleomorph ''Helicobasidium purpureum''), is the causal agent of violet root rot of carrots and other root vegetables.

Rhizoctonia Solani
''Rhizoctonia solani'' is a species of fungus in the order Cantharellales. Basidiocarps (fruit bodies) are thin, effused, and web-like, but the fungus is more typically encountered in its anamorphic state, as hyphae and sclerotia. The name ''Rhizoctonia solani'' is currently applied to a complex of related species that await further research. In its wide sense, ''Rhizoctonia solani'' is a facultative plant pathogen with a wide host range and worldwide distribution. It causes various plant diseases such as root rot, damping off, and wire stem. It can also form mycorrhizal associations with orchids. Taxonomy In 1858, the German plant pathologist Julius Kühn observed and described a fungus on diseased potato tubers and named it ''Rhizoctonia solani'', the species epithet referring to ''Solanum tuberosum'' (potato). The disease caused was well known before the discovery and description of the fungus. In 1956, Dutch mycologist M.A. Donk published the new name ''Thanatephorus cucumer ...

Oidium (genus)
''Oidium'' is a genus of Deuteromycetes, where traditionally most anamorphs of the order Erysiphales are included. Most of them are plant pathogens causing different forms of powdery mildew, for example: *''Oidium alphitoides'' (= ''O. quercinum'') = '' Microsphaera alphitoides'' (on oaks) *'' Oidium anacardii'' (= ''Acrosporium anacardii'') (on cashew) *'' Oidium arachidis'' (on peanut) *''Oidium asteris-punicei'' (= ''Erysiphe cichoracearum'') (on mangos) *''Oidium balsamii'' = '' Erysiphe verbasci'' (on mulleins) *''Oidium begoniae'' (=''O.cyclaminis'', ''O.lini'', ''O.violae'') = ''Erysiphe polyphaga'' (on ''Valerianella'', ''Calluna'' and '' Erica'') *''Oidium candicans'' (= ''Monilia candicans'') *''Oidium caricae'' (on papayas) *''Oidium caricae-papayae'' (on papayas) *''Oidium caricicola'' (on papayas) *''Oidium chrysanthemi'' = ''Erysiphe cichoracearum'' (on numerous plant species, especially Asteraceae) *'' Oidium carpini'' *'' Oidium chartarum'' (= ''Torula chartarum ...

Fusarium Oxysporum F
''Fusarium'' is a large genus of filamentous fungi, part of a group often referred to as hyphomycetes, widely distributed in soil and associated with plants. Most species are harmless saprobes, and are relatively abundant members of the soil microbial community. Some species produce mycotoxins in cereal crops that can affect human and animal health if they enter the food chain. The main toxins produced by these ''Fusarium'' species are fumonisins and trichothecenes. Despite most species apparently being harmless (some existing on the skin as commensal members of the skin flora), some ''Fusarium'' species and subspecific groups are among the most important fungal pathogens of plants and animals. The name of ''Fusarium'' comes from Latin ''fusus'', meaning a spindle. Taxonomy The taxonomy of the genus is complex. A number of different schemes have been used, and up to 1,000 species have been identified at times, with approaches varying between wide and narrow concepts of specia ...
