Fungi
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'' (''t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Opium Poppy
''Papaver somniferum'', commonly known as the opium poppy or breadseed poppy, is a species of flowering plant in the family Papaveraceae. It is the species of plant from which both opium and poppy seeds are derived and is also a valuable ornamental plant, grown in gardens. Its native range is probably the eastern Mediterranean, but is now obscured by ancient introductions and cultivation, being naturalized across much of Europe and Asia. This poppy is grown as an agricultural crop on a large scale, for one of three primary purposes. The first is to produce seeds that are eaten by humans, commonly known as poppy seed. The second is to produce opium for use mainly by the pharmaceutical industry. The third is to produce other alkaloids, mainly thebaine and oripavine, that are processed by the pharmaceutical industry into drugs such as hydrocodone and oxycodone. Each of these goals has special breeds that are targeted at one of these businesses, and breeding efforts (including biotec ...

Fungi Of Europe
A fungus (plural, : fungi or funguses) is any member of the group of Eukaryote, eukaryotic organisms that includes microorganisms such as yeasts and Mold (fungus), molds, as well as the more familiar mushrooms. These organisms are classified as a Kingdom (biology), 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.

Fungi Of Australia
The Fungi of Australia form an enormous and phenomenally diverse group, a huge range of freshwater, marine and terrestrial habitats with many ecological roles, for example as saprobes, parasites and mutualistic symbionts of algae, animals and plants, and as agents of biodeterioration. Where plants produce, and animals consume, the fungi recycle, and as such they ensure the sustainability of ecosystems. Knowledge about the fungi of Australia is meagre. Little is known about aboriginal cultural traditions involving fungi, or about aboriginal use of fungi apart from a few species such as Blackfellow's bread (''Laccocephalum mylittae''). Humans who came to Australia over the past couple of centuries brought no strong fungal cultural traditions of their own. Fungi have also been largely overlooked in the scientific exploration of Australia. Since 1788, research on Australian fungi, initially by botanists and later by mycologists, has been spasmodic and intermittent. At governmental lev ...

Monotypic Dothideomycetes Genera
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, ''Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda.'' ...

Plan Colombia
Plan Colombia was a United States foreign aid, military aid, and diplomatic initiative aimed at combating Colombian drug cartels and left-wing insurgent groups in Colombia. The plan was originally conceived in 1999 by the administrations of Colombian President Andrés Pastrana and U.S. President Bill Clinton, and signed into law in the United States in 2000. The official objectives of Plan Colombia were to end the Colombian armed conflict by increasing funding and training of Colombian military and para-military forces and creating an anti-cocaine strategy to eradicate coca cultivation. Partly as a result of the plan, FARC lost much of its power against the Colombian government. Sources conflict on its effects limiting cocaine production, however. US reports conclude that cocaine production in Colombia dropped 72% from 2001 to 2012, contradicting UN sources which found no change in cocaine production. Plan Colombia in its initial form existed until 2015, with the United States ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biological Weapon
A biological agent (also called bio-agent, biological threat agent, biological warfare agent, biological weapon, or bioweapon) is a bacterium, virus, protozoan, parasite, fungus, or toxin that can be used purposefully as a weapon in bioterrorism or biological warfare (BW). In addition to these living or replicating pathogens, toxins and biotoxins are also included among the bio-agents. More than 1,200 different kinds of potentially weaponizable bio-agents have been described and studied to date. Biological agents have the ability to adversely affect human health in a variety of ways, ranging from relatively mild allergic reactions to serious medical conditions, including serious injury, as well as serious or permanent disability or even death. Many of these organisms are ubiquitous in the natural environment where they are found in water, soil, plants, or animals. Bio-agents may be amenable to "weaponization" to render them easier to deploy or disseminate. Genetic modification ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fusarium Oxysporum
''Fusarium oxysporum'' (Schlecht as emended by Snyder and Hansen), an ascomycete fungus, comprises all the species, varieties and forms recognized by Wollenweber and Reinking within an infrageneric grouping called section Elegans. It is part of the family Nectriaceae. Although their predominant role in native soils may be as harmless or even beneficial plant endophytes or soil saprophytes, many strains within the ''F. oxysporum'' complex are soil borne pathogens of plants, especially in agricultural settings. Taxonomy While the species, as defined by Snyder and Hansen, has been widely accepted for more than 50 years, more recent work indicates this taxon is actually a genetically heterogeneous polytypic morphospecies, whose strains represent some of the most abundant and widespread microbes of the global soil microflora. Genome The ' family of transposable elements was first discovered by Daboussi ''et al.'', 1992 in several ''formae speciales'' and Davière ''et al.'', 2001 ...

Colombia
Colombia (, ; ), officially the Republic of Colombia, is a country in South America with insular regions in North America—near Nicaragua's Caribbean coast—as well as in the Pacific Ocean. The Colombian mainland is bordered by the Caribbean Sea to the north, Venezuela to the east and northeast, Brazil to the southeast, Ecuador and Peru to the south and southwest, the Pacific Ocean to the west, and Panama to the northwest. Colombia is divided into 32 departments and the Capital District of Bogotá, the country's largest city. It covers an area of 1,141,748 square kilometers (440,831 sq mi), and has a population of 52 million. Colombia's cultural heritage—including language, religion, cuisine, and art—reflects its history as a Spanish colony, fusing cultural elements brought by immigration from Europe and the Middle East, with those brought by enslaved Africans, as well as with those of the various Amerindian civilizations that predate colonization. Spanish is th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leaf Blight
Blight refers to a specific symptom affecting plants in response to infection by a pathogenic organism. Description Blight is a rapid and complete chlorosis, browning, then death of plant tissues such as leaves, branches, twigs, or floral organs. Accordingly, many diseases that primarily exhibit this symptom are called blights. Several notable examples are: * Late blight of potato, caused by the water mold ''Phytophthora infestans'' (Mont.) de Bary, the disease which led to the Great Irish Famine * Southern corn leaf blight, caused by the fungus ''Cochliobolus heterostrophus'' (Drechs.) Drechs, anamorph '' Bipolaris maydis'' (Nisikado & Miyake) Shoemaker, incited a severe loss of corn in the United States in 1970. * Chestnut blight, caused by the fungus ''Cryphonectria parasitica'' (Murrill) Barr, has nearly completely eradicated mature American chestnuts in North America. * Citrus blight, caused by an unknown agent, infects all citrus scions. * Fire blight of pome fruit ...
