Alfalfa
Alfalfa () (''Medicago sativa''), also called lucerne, is a perennial flowering plant in the legume family Fabaceae. It is cultivated as an important forage crop in many countries around the world. It is used for grazing, hay, and silage, as well as a green manure and cover crop. The name alfalfa is used in North America. The name lucerne is the more commonly used name in the United Kingdom, South Africa, Australia, and New Zealand. The plant superficially resembles clover (a cousin in the same family), especially while young, when trifoliate leaves comprising round leaflets predominate. Later in maturity, leaflets are elongated. It has clusters of small purple flowers followed by fruits spiralled in 2 to 3 turns containing 10–20 seeds. Alfalfa is native to warmer temperate climates. It has been cultivated as livestock fodder since at least the era of the ancient Greeks and Romans. Etymology The word ''alfalfa'' is a Spanish modification of the Arabic word ''al-faṣfaṠ...

Sclerotinia Sclerotiorum
''Sclerotinia sclerotiorum'' is a plant pathogenic fungus and can cause a disease called white mold if conditions are conducive. ''S. sclerotiorum'' can also be known as cottony rot, watery soft rot, stem rot, drop, crown rot and blossom blight. A key characteristic of this pathogen is its ability to produce black resting structures known as sclerotia and white fuzzy growths of mycelium on the plant it infects. These sclerotia give rise to a fruiting body in the spring that produces spores in a sac which is why fungi in this class are called sac fungi (Ascomycota). This pathogen can occur on many continents and has a wide host range of plants. When ''S. sclerotiorum'' is onset in the field by favorable environmental conditions, losses can be great and control measures should be considered. Hosts and symptoms ''S. sclerotiorum'' is among the most omnivorous of plant pathogens and so would not make a good mycoherbicide. Economically significant hosts include ''Vicia faba'', for w ...

Fusarium
''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 speci ...

Nectria Haematococca
''Fusarium solani'' is a species complex of at least 26 closely related filamentous fungi in the division Ascomycota, family Nectriaceae. It is the anamorph of '' Nectria haematococca''. It is a common soil fungus and colonist of plant materials. ''Fusarium solani'' is implicated in plant disease as well as human disease notably infection of the cornea of the eye. History and taxonomy The genus ''Fusarium'' was described in 1809 by Link. In the 1930s, Wollenweber and Reinking organized the genus ''Fusarium'' into sections, including ''Martiella'' and ''Ventricosum,'' which were collapsed together by Snyder and Hansen in the 1940s to form a single species, ''Fusarium solani;'' one of nine ''Fusarium'' species they recognized based on morphological features. The current concept of ''F. solani'' is as a species complex consisting of multiple, closely related and morphologically poorly distinguishable, "cryptic" species with characteristic genetic differences.

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 ...
