Crivellia Papaveracea
''Alternaria penicillata'' is a species of fungi in the family Pleosporaceae, which causes leaf blight of opium poppy. The fungus is found in Europe, Australia, India, Japan, Nepal, Pakistan, South Africa, Turkey, USA and Zambia. It was formerly ''Crivellia papaveracea'' in the monotypic genus ''Crivellia''. With DNA analyses showing that it was related to ''Alternaria brassicicola'' , '' Alternaria japonica'' , and '' Ulocladium alternariae'' . Genus ''Crivellia'' was named after mycologist Paolo Giuseppe Crivelli (fl. 1981). It was found in Russia and Ukraine. In 2013, a new DNA study was carried out and reclassified former genera; ''Allewia'', ''Brachycladium'', ''Chalastospora'', ''Chmelia'', ''Crivellia'', ''Embellisia'', ''Lewia'', ''Nimbya'', ''Sinomyces'', ''Teretispora'', ''Ulocladium'', ''Undifilum'' and ''Ybotromyces'' as synonymy with genus ''Alternaria''. As accepted by Wijayawardene et al. 2020. "Agent Green" in Colombia In 2000, the government of Colombia propo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biological Weapon
Biological agents, also known as biological weapons or bioweapons, are pathogens used as weapons. In addition to these living or replicating pathogens, toxins and Toxin#Biotoxins, 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. Some biological agents have the ability to adversely affect health, human health in a variety of ways, ranging from relatively mild allergy, allergic reactions to serious medical conditions, including serious injury, as well as serious or permanent disability or 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 engineering, Genetic modification may enhance their incapacitating or lethal properties, or render them impervious to conventional treatments or preventive ...

Fungi Of North America
A fungus (: fungi , , , or ; 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 one of the traditional eukaryotic kingdoms, along with Animalia, Plantae, and either Protista or 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'' or ''Eum ...

Fungi Of Australia
The fungi of Australia form an enormous and diverse group, encompassing a huge range of freshwater, marine and terrestrial habitats with many ecological roles, including saprobes, parasites and mutualistic symbionts of algae, animals and plants, as well 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 ...

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. The plan was originally conceived in 1999 by the administrations of Colombian President Andrés Pastrana Arango 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, the Revolutionary Armed Forces of Colombia, 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 exist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coca
Coca is any of the four cultivated plants in the family Erythroxylaceae, native to western South America. Coca is known worldwide for its psychoactive alkaloid, cocaine. Coca leaves contain cocaine which acts as a mild stimulant when chewed or consumed as tea, with slower absorption than purified cocaine and no evidence of addiction or withdrawal symptoms from natural use. The coca plant is a shrub-like bush with curved branches, oval leaves featuring distinct curved lines, small yellowish-white flowers that develop into red berries. Genomic analysis reveals that coca, a culturally and economically important plant, was domesticated two or three separate times from the wild species ''Erythroxylum gracilipes'' by different South American groups during the Holocene. Chewing coca in South America began at least 8,000 years ago, as evidenced by coca leaves and calcite found in house floors in Peru’s Nanchoc Valley, suggesting early communal use alongside the rise of farming. ...

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 ...
