Coffee
Coffee is a drink prepared from roasted coffee beans. Darkly colored, bitter, and slightly acidic, coffee has a stimulant, stimulating effect on humans, primarily due to its caffeine content. It is the most popular hot drink in the world. Seeds of the ''Coffea'' plant's fruits are separated to produce unroasted green coffee beans. The beans are Coffee roasting, roasted and then ground into fine particles that are typically steeped in hot water before being filtered out, producing a cup of coffee. It is usually served hot, although chilled or iced coffee is common. Coffee can be prepared and presented in a variety of ways (e.g., espresso, French press, caffè latte, or already-brewed canned coffee). Sugar, sugar substitutes, milk, and cream are often used to mask the bitter taste or enhance the flavor. Though coffee is now a global commodity, it has a History of coffee, long history tied closely to food traditions around the Red Sea. The earliest credible evidence of coffee d ...

Phanerochaete Salmonicolor
''Erythricium salmonicolor'' is a species of fungus in the family Corticiaceae. Basidiocarps are effused, corticioid, smooth, and pinkish and grow on wood. The fungus is a commercially significant plant pathogen which has become a serious problem, especially in Brazil. ''Erythricium salmonicolor'' causes Pink Disease, most commonly in ''Citrus'', although ''E. salmonicolor'' has a wide host range including rubber and cacao trees. Pink Disease causes branch and stem die-back due to canker formation. The cankers are recognizable by gum exudation and longitudinal splitting of the bark. Hosts and symptoms ''Erythricium salmonicolor'' has a very broad host range. The host plants of greatest importance include rubber, tea, coffee, cacao, grapefruit, orange, nutmeg, mango, apple, coca, and kola. Pink Disease can cause heavy losses including individual branch death to the loss of the whole tree in cases where the main stem or several branches are affected. ''E. salmonicolor'' causes gird ...

Meloidogyne
Root-knot nematodes are plant-parasitic nematodes from the genus ''Meloidogyne''. They exist in soil in areas with hot climates or short winters. About 2000 plants worldwide are susceptible to infection by root-knot nematodes and they cause approximately 5% of global crop loss. Root-knot nematode larvae infect plant roots, causing the development of root-knot galls that drain the plant's photosynthate and nutrients. Infection of young plants may be lethal, while infection of mature plants causes decreased yield. Economic impact Root-knot nematodes (''Meloidogyne'' spp.) are one of the three most economically damaging genera of plant-parasitic nematodes on horticultural and field crops. Root-knot nematodes are distributed worldwide, and are obligate parasites of the roots of thousands of plant species, including monocotyledonous and dicotyledonous, herbaceous and woody plants. The genus includes more than 90 species, with some species having several races. Four ''Meloidogyne'' spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

Fusarium Xylarioides
''Gibberella xylarioides'' (''Fusarium xylarioides'') is a species of fungus in the family Nectriaceae. It is the causative agent of coffee wilt disease (CWD). The disease caused a severe problem in several countries in West and East Africa during the 1940s and 1950s. CWD was first seen in ''Coffea liberica''. Hosts Main hosts ''Coffea arabica'' (arabica coffee) ''Coffea canephora'' (robusta coffee) ''Coffea liberica'' (Liberian coffee tree) Other hosts ''Gossypium'' (cotton) ''Musa × paradisiaca'' (plantain) Signs and symptoms Similar to other vascular wilt pathogens, the fungus colonizes the xylem and causes the flow of water to be cut off. It can be diagnosed by several visual signs. The leaves can wilt, have vein necrosis, and abscission. The coffee bark, when scraped with a knife, will have a blue-black coloration. The berries will appear as though they are ripening prematurely but will stay on the coffee plant after the leaves have fallen off. Necrosis can often b ...

Corticium Koleroga
''Rhizoctonia noxia'' is a species of fungus in the order Cantharellales. Basidiocarps (fruit bodies) are thin, effused, and web-like. The species is tropical to sub-tropical and is mainly known as a plant pathogen, the causative agent of "kole-roga" or black rot of coffee and various blights of citrus and other trees. Taxonomy The fungus responsible for kole-roga of coffee was sent from India to Mordecai Cubitt Cooke at the Royal Botanic Gardens, Kew who named it ''Pellicularia koleroga'' in 1876. Cooke, however, described only hyphae and some small warted spores, later presumed to be from a contaminating mould. As a result Donk, when reviewing ''Pellicularia'' in 1954, dismissed both the genus and ''P. koleroga'' as "nomina confusa", later (1958) substituting the new name ''Koleroga noxia'' for the species. Based on a re-examination of specimens, Roberts (1999) considered ''Koleroga'' to be a synonym of ''Ceratobasidium''. Molecular research, based on cladistic analysis of DN ...

Stilbum Flavidum
''Mycena citricolor'' is a species of mushroom-forming fungus in the family Mycenaceae. It is a plant pathogen producing leaf spots on coffee plants. This fungus causes the disease commonly known as American Leaf Spot. ''Mycena citricolor'' affects coffee plants, primarily in Latin America, but can grow on other plants as well. This fungus can grow on all parts of the coffee plant including the leaves, stems and fruits. When grown on the leaves, ''Mycena citricolor'' results in leaves with holes that often fall from the plant. Description The ''Mycena'' fungus can be identified growing on somewhat circular, brown spots on coffee leaves. The brown spots are caused by the presence of the parasitic fungus and by looking at the leaves closely, small mushrooms with luminescence can be seen. The fungi's luminescence is active in the presence and absence of light. Its luminescence is also affected by the temperature of its environment. See also * List of bioluminescent fungi ] Fou ...
