Camellia Sinensis
''Camellia sinensis'' is a species of evergreen shrub or small tree in the flowering plant family Theaceae. Its leaves and leaf buds are used to produce the popular beverage, tea. Common names include tea plant, tea shrub, and tea tree (not to be confused with ''Melaleuca alternifolia'', the source of tea tree oil, or the genus ''Leptospermum'' commonly called tea tree). White tea, yellow tea, green tea, oolong, dark tea (which includes pu-erh tea) and black tea are all harvested from one of two major varieties grown today, ''C. sinensis'' var. ''sinensis'' and ''C. s.'' var. ''assamica'', but are processed differently to attain varying levels of oxidation with black tea being the most oxidized and green being the least. Kukicha (twig tea) is also harvested from ''C. sinensis'', but uses twigs and stems rather than leaves. Nomenclature and taxonomy The generic name ''Camellia'' is taken from the Latinized name of Rev. Georg Kamel, SJ (1661–1706), a Moravian-born Jesuit ...

Glomerella Cingulata
''Glomerella cingulata'' is a fungal plant pathogen, being the name of the sexual stage (teleomorph) while the more commonly referred to asexual stage ( anamorph) is called ''Colletotrichum gloeosporioides''. For most of this article the pathogen will be referred to as ''C. gloeosporioides.'' This pathogen is a significant problem worldwide, causing anthracnose and fruit rotting diseases on hundreds of economically important hosts. Hosts and symptoms ''C. gloeosporioides'' has an extremely broad host range, causing anthracnose disease on a variety of crops such as cereals and grasses, legumes, fruits, vegetables, perennial crops, and trees. It has been observed as infecting harvested durian of the species ''Durio graveolens''. Some studies suggest that ''C. gloeosporioides'' has sub-populations specific to each host.Nelson, C.

Gubler, Plant Disease, April 2008, Volume 92, Number 4, pages 519-529, It also infects '' Biancaea sappan'', a species of flowering tree also known as Sappanwood. On rare occasions it has been found to cause fungal keratitis, lesions on nail and subcutaneous tissue. It has been implicated in the widespread mortality of baobab (''Adansonia digitata'') trees in Southern Africa.

Exobasidium Vexans
''Exobasidium vexans'' is a plant pathogen affecting tea. Blister blight caused by ''Exobasidium vexans'' is a devastating leaf disease in tea (''Camellia sinensis ''Camellia sinensis'' is a species of evergreen shrub or small tree in the flowering plant family Theaceae.

This disease causes serious crop losses under inclement weather conditions besides affecting quality of made tea. Although tea cultivars show varying degrees of resistance/susceptibility to blister blight, a cultivar showing total resistance to blister blight has not yet been identified. The mature two-celled basidiospores are very easily dislodged from the sterigmata and are usually to be found on the surface of the blister. In carefully collected material we have seen the mature two-celled basidiospores attached to sterigm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Phytopathological Society
The American Phytopathological Society (APS) is an international scientific organization devoted to the study of plant diseases (phytopathology). APS promotes the advancement of modern concepts in the science of plant pathology and in plant health management in agricultural, urban and forest settings. The Society has nearly 5,000 plant pathologists and scientists worldwide. It is the oldest and largest organization of its type in the world. It is also a member of the International Society for Plant Pathology. APS provides information on the latest developments and research advances in plant health science through its journals and its publishing arm, APS Press. APS advocates and participates in the exchange of plant health information with public policy makers and the larger scientific community, and it provides advice on education and training. History The society was founded in December 1908, and the first regular meeting was held in December 1909. It was the first scien ...

Ceratobasidium
''Ceratobasidium'' is a genus of fungi in the order Cantharellales. Basidiocarps (fruit bodies) are effused and the genus is sometimes grouped among the corticioid fungi, though species also retain features of the heterobasidiomycetes. Anamorphic forms were formerly referred to the genus ''Ceratorhiza'', but this is now considered a synonym of ''Rhizoctonia''. ''Ceratobasidium'' species, excluding the type, are also now considered synonymous with ''Rhizoctonia'' and some species have been transferred to the latter genus. Species are saprotrophic, but several are also facultative plant pathogens, causing a number of commercially important crop diseases. Some are also endomycorrhizal associates of orchids. Taxonomy The name ''Ceratobasidium'' was introduced in 1935 by American mycologist D.P. Rogers to accommodate species of the old form genus '' Corticium'' that showed affinities with the heterobasidiomycetes. These affinities were the possession of large sterigmata ("cerato b ...

Rosellinia Bunoides
''Rosellinia'' is a genus of fungi in the family Xylariaceae consisting of over 90 species. Several of the species in this genus are plant pathogens. Fossils of ''Rosellinia'' have been found in 12 million year old rocks from central England. The genus was circumscribed by Giuseppe De Notaris in Giorn. Bot. Ital. vol.1 (Issue 1) on page 334 in 1844. The genus name of ''Rosellinia'' is in honour of Ferdinando Pio Rosellini (1814–1872), who was an Italian mathematician A mathematician is someone who uses an extensive knowledge of mathematics in their work, typically to solve mathematical problems. Mathematicians are concerned with numbers, data, quantity, structure, space, models, and change. History On ... and botanist.
