Bacillus Megaterium
''Bacillus megaterium'' is a rod-like, Gram-positive, mainly aerobic spore forming bacterium found in widely diverse habitats.De Vos, P. ''et al.'' Bergey's Manual of Systematic Bacteriology: Volume 3: The Firmicutes. ''Springer'' (2009) It has a cell length of up to 4 µm and a diameter of 1.5 µm, which is quite large for a bacteria. The cells often occur in pairs and chains, where the cells are joined together by polysaccharides on the cell walls. In the 1960s, prior to the utilization of ''Bacillus subtilis'' for this purpose, ''B. megaterium'' was the main model organism among Gram-positive bacteria for intensive studies on biochemistry, sporulation and bacteriophages. Recently, its popularity has started increasing in the field of biotechnology for its recombinant protein production capacity.Bunk, B. ''et al.'' A short story about a big magic bug. ''Bioengineered Bugs'' 1:85–91 (2010) This species has been recently transferred into the genus ''Priestia''. The c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Valsa Sordida
''Valsa sordida'' is a species of fungus within the family Valsaceae. A plant pathogen, it causes dieback of small branches and twigs of broad-leaved trees, usually poplar. It is found in Africa, Australasia, Europe, and North and South America. The anamorph In mycology, the terms teleomorph, anamorph, and holomorph apply to portions of the life cycles of fungi in the phyla Ascomycota and Basidiomycota: *Teleomorph: the sexual reproductive stage (morph), typically a fruiting body. *Anamorph: an ase ... is ''Cytospora chrysosperma''.

Cytospora Chrysosperma
Diamond willow is a type of tree with wood that is deformed into diamond-shaped segments with alternating colors. This is most likely the result of attack by a fungus (''Valsa sordida'' and possibly others), which causes cankers to form in the wood in response to the infection.H.J. Lutz, "Observation on 'diamond willow,' with Particular Reference to Its Occurrence in Alaska", The American Midland Naturalist 60(1):176-185, 1958. Diamond willow is prized by wood carvers and furniture makers for its strong contrasting colors (red and white) and its sculptural irregularity of shape. There are at least six different species that have been identified as being susceptible to diamonding, including ''Salix bebbiana'', the most common diamond willow, plus '' S. pseudomonticola'', '' S. arbusculoides'', '' S. discolor'', '' S. scouleriana'', and '' S. alaxensis''. The diamonding is usually found with a branch at its center or is found in the Y of a tree. Diamonding in willow does not se ...

Diapleella Coniothyrium
''Leptosphaeria coniothyrium'' is a plant pathogen. It can be found around the world. Host symptoms and signs All brambles, especially black raspberries, are susceptible to cane blight. The causal agent for Cane Blight is the fungus ''Leptosphaeria coniothyrium''. The infection spreads internally first, therefore outwardly noticeable symptoms typically do not appear quickly. Symptoms could be exposed by peeling back the xylem and looking at the internal plant tissue. Healthy tissue would appear green, whereas diseased tissue develop dark lesions and vascular streaking. By late summer or fall, well after the initial infection, dark red or purple lesions can appear near wounded sites. Sometimes, large cankers develop causing necrosis and death of the cane in the following year. In the spring buds may fail to break, lateral branches may appear wilted, or canes may die as the fruit begins to ripen. Canes can also break or appear brittle near infection sites. Signs of cane blight ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
