Naohidemyces Vaccinii
''Naohidemyces vaccinii'' is a plant pathogen that affects members of the '' Vaccinium'' and '' Tsuga'' genera, causing leaf rust on lingonberries, blueberries, and cranberries, and early needle cast on hemlocks. ''Naohidemyces vaccinii'' is found on the ''Vaccinium'' genus in Canada, the United States (AK, ME, NH), the United Kingdom, Europe, Russia, China, Korea, and Japan, and on hemlock in AK, ID, WA in the United States, BC in Canada, and Japan. Taxonomy ''Naohidemyces vaccinii'' is a basidiomycete Basidiomycota () is one of two large divisions that, together with the Ascomycota, constitute the subkingdom Dikarya (often referred to as the "higher fungi") within the kingdom Fungi. Members are known as basidiomycetes. More specifically, Basi ... rust fungi with a number of different synonyms, including '' Pucciniastrum vaccinii'' and ''Pucciniastrum myrtilli'', but was moved to the ''Naohidemyces'' genus due to its dome-shaped covering over the aecia.  ''N. vaccinii'' is ...

Blueberry
Blueberries are a widely distributed and widespread group of perennial flowering plants with blue or purple berries. They are classified in the section ''Cyanococcus'' within the genus ''Vaccinium''. ''Vaccinium'' also includes cranberries, bilberries, huckleberries and Madeira blueberries. Commercial blueberries—both wild (lowbush) and cultivated (highbush)—are all native to North America. The highbush varieties were introduced into Europe during the 1930s. Blueberries are usually prostrate shrubs that can vary in size from to in height. In commercial production of blueberries, the species with small, pea-size berries growing on low-level bushes are known as "lowbush blueberries" (synonymous with "wild"), while the species with larger berries growing on taller, cultivated bushes are known as "highbush blueberries". Canada is the leading producer of lowbush blueberries, while the United States produces some 40% of the world supply of highbush blueberries. Origin and h ...

Pucciniastrum
''Pucciniastrum'' is a genus of Basidiomycota fungi. ''Pucciniastrum'' species, like all rust fungi, are obligate plant parasites. The genus name of ''Pucciniastrum'' is in honour of Tommaso Puccini (died 1735), who was an Italian doctor and botanist who taught Anatomy at Hospital of Santa Maria Nuova in Florence. The genus was circumscribed by Gustav Heinrich Otth in Mitt. Naturf. Ges. Bern 476-479: 61, 71-75, 80-81, 84, 87 in 1861. Species As accepted by Species Fungorum; * '' Pucciniastrum aceris'' * '' Pucciniastrum actinidiae'' * '' Pucciniastrum agrimoniae'' * '' Pucciniastrum alaskanum'' * '' Pucciniastrum areolatum'' * ''Pucciniastrum asterum'' * '' Pucciniastrum beringianum'' * '' Pucciniastrum boehmeriae'' * '' Pucciniastrum brachybotrydis'' * ''Pucciniastrum castaneae'' * ''Pucciniastrum celastri'' * ''Pucciniastrum circaeae'' * ''Pucciniastrum clemensiae'' * ''Pucciniastrum corchoropsidis'' * ''Pucciniastrum coriariae'' * ''Pucciniastrum corni'' * ...

Fungi Of Asia
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''true fungi ...

Taxa Named By Lewis David De Schweinitz
In biology, a taxon (back-formation from ''Taxonomy (biology), taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular Taxonomic rank, ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's Linnaean taxonomy, system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard de Jussieu, Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of bio ...

Teliomycotina
The Pucciniomycetes (formerly known as the Urediniomycetes) are a class of fungi in the Pucciniomycotina subdivision of the Basidiomycota. The class contains 5 orders, 21 families, 190 genera, and 8016 species. It includes several important plant pathogens causing forms of fungal rust. Characteristics Pucciniomycetes develop no basidiocarp, karyogamy occurs in a thick-walled resting spore (teliospore), and meiosis occurs upon germination of teliospore. They have simple septal pores without membrane caps and disc-like spindle pole bodies. Except for a few species, the basidia, when present, are transversally septate. Mannose is the major cell wall carbohydrate, glucose, fucose and rhamnose are the less prevalent neutral sugars and xylose Xylose ( grc, ξύλον, , "wood") is a sugar first isolated from wood, and named for it. Xylose is classified as a monosaccharide of the aldopentose type, which means that it contains five carbon atoms and includes an aldehyde functional g ...

Basidiospore
A basidiospore is a reproductive spore produced by Basidiomycete fungi, a grouping that includes mushrooms, shelf fungi, rusts, and smuts. Basidiospores typically each contain one haploid nucleus that is the product of meiosis, and they are produced by specialized fungal cells called basidia. Typically, four basidiospores develop on appendages from each basidium, of which two are of one strain and the other two of its opposite strain. In gills under a cap of one common species, there exist millions of basidia. Some gilled mushrooms in the order Agaricales have the ability to release billions of spores. The puffball fungus ''Calvatia gigantea'' has been calculated to produce about five trillion basidiospores. Most basidiospores are forcibly discharged, and are thus considered ballistospores. These spores serve as the main air dispersal units for the fungi. The spores are released during periods of high humidity and generally have a night-time or pre-dawn peak concentration in the ...

Teliospore
Teliospore (sometimes called teleutospore) is the thick-walled resting spore of some fungi ( rusts and smuts), from which the basidium arises. Development They develop in '' telia'' (sing. ''telium'' or ''teliosorus''). The telial host is the primary host in heteroecious rusts. The aecial host is the alternate host (look for pycnia and aecia). These terms apply when two hosts are required by a heteroecious rust fungus to complete its life cycle. Morphology Teliospores consist of one, two or more dikaryote cells. Teliospores are often dark-coloured and thick-walled, especially in species where they overwinter (acting as chlamydospores). Two-celled teliospores formerly defined the genus ''Puccinia''. Here the wall is particularly thick at the tip of the terminal cell which extends into a beak in some species. Teliospores consist of dikaryote cells. As the teliospore cells germinate, the nuclei undergo karyogamy and thereafter meiosis, giving rise to a four-celled basidiu ...

Urediniospore
Urediniospores (or uredospores) are thin-walled spores produced by the uredium, a stage in the life-cycle of rusts. Development ''Urediniospores'' develop in the uredium, generally on a leaf's under surface. Morphology *Urediniospores usually have two dikaryote nuclei within one cell. In mass they are usually pale brown in contrast to teliospores which are generally dark brown. See also *Chlamydospore *Urediniomycetes *Pycniospore *Aeciospore *Teliospore *Ustilaginomycetes Ustilaginomycetes is the class of true smut fungi. They are plant parasites with about 1400 recognised species in 70 genera. They have a simple septum with a septal pore cap, this is different from Agaricomycotina which has a dolipore septum with ... * Rust fungus: Spores References *C.J. Alexopolous, Charles W. Mims, M.

Chlorosis
In botany, chlorosis is a condition in which leaves produce insufficient chlorophyll. As chlorophyll is responsible for the green color of leaves, chlorotic leaves are pale, yellow, or yellow-white. The affected plant has little or no ability to manufacture carbohydrates through photosynthesis and may die unless the cause of its chlorophyll insufficiency is treated and this may lead to a plant diseases called rusts, although some chlorotic plants, such as the albino ''Arabidopsis thaliana'' mutant ''ppi2'', are viable if supplied with exogenous sucrose. The word ''chlorosis'' is derived from the Greek ''khloros'' meaning "greenish-yellow", "pale green", "pale", "pallid", or "fresh". In viticulture, the most common symptom of poor nutrition in grapevines is the yellowing of grape leaves caused by chlorosis and the subsequent loss of chlorophyll. This is often seen in vineyard soils that are high in limestone such as the Italian wine region of Barolo in the Piedmont, the Spanish wi ...
