Carnation
''Dianthus caryophyllus'' (), commonly known as the carnation or clove pink, is a species of ''Dianthus''. It is likely native to the Mediterranean region but its exact range is unknown due to extensive cultivation for the last 2,000 years.Med-Checklist''Dianthus caryophyllus''/ref>Flora Europaea''Dianthus caryophyllus''/ref>Blamey, M. & Grey-Wilson, C. (1989). ''Flora of Britain and Northern Europe''. Huxley, A., ed. (1992). ''New RHS Dictionary of Gardening''. Macmillan . Taxonomy Carnations were mentioned in Greek literature 2,000 years ago. The term ''dianthus'' was coined by Greek botanist Theophrastus, and is derived from the Ancient Greek words for divine ("dios") and flower ("anthos"). The name "carnation" is believed to come from the Latin ''corona-ae'', a "wreath, garland, chaplet, crown",Cassell's Latin Dictionary, Marchant, J.R.V, & Charles, Joseph F., (Eds.), Revised Edition, 1928 as it was one of the flowers used in Greek and Roman ceremonial crowns, or possibly ...

Fusarium Graminearum
''Gibberella zeae'', also known by the name of its anamorph ''Fusarium graminearum'', is a fungal plant pathogen which causes fusarium head blight (FHB), a devastating disease on wheat and barley. The pathogen is responsible for billions of dollars in economic losses worldwide each year. Infection causes shifts in the amino acid composition of wheat, resulting in shriveled kernels and contaminating the remaining grain with mycotoxins, mainly deoxynivalenol (DON), which inhibits protein biosynthesis; and zearalenone, an estrogenic mycotoxin. These toxins cause vomiting, liver damage, and reproductive defects in livestock, and are harmful to humans through contaminated food. Despite great efforts to find resistance genes against ''F. graminearum'', no completely resistant variety is currently available. Research on the biology of ''F. graminearum'' is directed towards gaining insight into more details about the infection process and reveal weak spots in the life cycle of this pathog ...

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 ...

Phytophthora Nicotianae Var
''Phytophthora'' (from Greek (''phytón''), "plant" and (), "destruction"; "the plant-destroyer") is a genus of plant-damaging oomycetes (water molds), whose member species are capable of causing enormous economic losses on crops worldwide, as well as environmental damage in natural ecosystems. As well as impacting large scale agriculture, ''Phytophthora'' is a nuisance to garden and indoor plant hobbyists as well as bonsai artists. The cell wall of ''Phytophthora'' is made up of cellulose. The genus was first described by Heinrich Anton de Bary in 1875. Approximately 170 species have been described, although 100–500 undiscovered ''Phytophthora'' species are estimated to exist. Pathogenicity ''Phytophthora'' spp. are mostly pathogens of dicotyledons, and many are relatively host-specific parasites. ''Phytophthora cinnamomi'', though, infects thousands of species ranging from club mosses, ferns, cycads, conifers, grasses, lilies, to members of many dicotyledonous familie ...

Pythium Ultimum
''Pythium ultimum'' is a plant pathogen. It causes the damping off and root rot diseases of hundreds of diverse plant hosts including corn, soybean, potato, wheat, fir, and many ornamental species. ''P. ultimum'' belongs to the peronosporalean lineage of oomycetes, along with other important plant pathogens such as ''Phytophthora'' spp. and many genera of downy mildews. ''P. ultimum'' is a frequent inhabitant of fields, freshwater ponds, and decomposing vegetation in most areas of the world. Contributing to the widespread distribution and persistence of ''P. ultimum'' is its ability to grow saprotrophically in soil and plant residue. This trait is also exhibited by most ''Pythium'' spp. but not by the related ''Phytophthora'' spp., which can only colonize living plant hosts. Pathology and disease management Infections of seeds and roots are initiated by both the mycelia and spores of ''P. ultimum''. Two spore types are made, depending on the strain. ''P. ultimum'' is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pythium
''Pythium'' is a genus of parasitic oomycetes. They were formerly classified as fungi. Most species are plant parasites, but ''Pythium insidiosum'' is an important pathogen of animals, causing pythiosis. The feet of the fungus gnat are frequently a vector for their transmission. Morphology ;Hyphae: ''Pythium'' species, like others in the family Pythiaceae, are usually characterized by their production of coenocytic hyphae without septations. ;Oogonia: Generally contain a single oospore. ;Antheridia: Contain an elongated and club-shaped antheridium. Ecological importance ''Pythium''-induced root rot is a common crop disease. When the organism kills newly emerged or emerging seedlings, it is known as damping off, and is a very common problem in fields and greenhouses. Thus there is tremendous interest in genetic host resistance, but no crop has ever developed adequate resistance to ''Pythium''. This disease complex usually involves other pathogens such as ''Phytophthora'' and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phymatotrichum Omnivorum
Texas root rot (also known as Phymatotrichopsis root rot, Phymatotrichum root rot, cotton root rot, or, in the older literature, Ozonium root rot) is a disease that is fairly common in Mexico and the southwestern United States resulting in sudden wilt and death of affected plants, usually during the warmer months. It is caused by a soil-borne fungus named ''Phymatotrichopsis omnivora'' that attacks the roots of susceptible plants. It was first discovered in 1888 by Pammel and later named by Duggar in 1916. A monograph of this disease, which includes a historical review, was written by R.B. Streets and H.E. Bloss in 1973. Host and symptoms ''Phymatotrichopsis omnivora'' is a necrotic fungal pathogen that has a very broad host range, attacking almost 2000 dicotyledonous species. It inhabits alkaline, calcareous soils in southwestern United States. It particularly targets dicots as most monocots are immune. Economically important plant hosts affected by the pathogen include: p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Botryotinia Fuckeliana
''Botryotinia'' is a genus of ascomycete fungi causing several plant diseases. The anamorphs of ''Botryotinia'' are mostly included in the "imperfect fungi" genus ''Botrytis''. The genus contains 22 species and one hybrid. Plant diseases caused by ''Botryotinia'' species appear primarily as blossom blights and fruit rots but also as leaf spots and bulb rots in the field and in stored products. The fungi induce host cell death resulting in progressive decay of infected plant tissue, whence they take nutrients. Sexual reproduction takes place with ascospores produced in apothecia, conidia are the means of asexual reproduction. Sclerotia of plano-convexoid shape are typical. Some species also cause damping off, killing seeds or seedlings during or before germination. ''Botryotinia fuckeliana'' (or its anamorph ''Botrytis cinerea'') is an important species for wine industry as well as horticulture. Other economically important species include ''Botryotinia convoluta'' (the type spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
