Vetch : ウィキペディア英語版
Vicia

''Vicia'' is a genus of about 140 species of flowering plants commonly known as vetches. It is in the legume family (Fabaceae). Member species are native to Europe, North America, South America, Asia and Africa. Some other genera of their subfamily Faboideae also have names containing "vetch", for example the vetchlings (''Lathyrus'') or the milk-vetches (''Astragalus''). The broad bean (''Vicia faba'') is sometimes separated in a monotypic genus ''Faba''; although not often used today, it is of historical importance in plant taxonomy as the namesake of the order Fabales, the Fabaceae and the Faboideae. The tribe Vicieae in which the vetches are placed is named after the genus' current name. Among the closest living relatives of vetches are the lentils (''Lens'') and the true peas (''Pisum'').
==Use by humans==

Bitter vetch (''V. ervilia'') was one of the first domesticated crops. It was grown in the Near East about 9,500 years ago, starting perhaps even one or two millennia earlier during the Pre-Pottery Neolithic A. By the time of the Central European Linear Pottery culture – about 7,000 years ago – broad bean (''V. faba'') had also been domesticated. Vetch has been found at Neolithic and Eneolithic sites in Bulgaria, Hungary and Slovakia. And at the same time, at the opposite end of Eurasia, the Hoabinhian people also utilized the broad bean in their path towards agriculture, as shown by the seeds found in Spirit Cave, Thailand.〔

Though Bernard of Clairvaux shared bread of vetch meal with his monks during the famine of 1124-26, an emblem of humility, eventually the Bitter Vetch was dropped from human use, save as a crop of last resort in times of starvation: vetches "featured in the frugal diet of the poor until the eighteenth century, and even reappeared on the black market in the South of France during the Second World War", Maguelonne Toussaint-Samat, of Marseillais background, has remarked. Broad beans remained prominent though, be it in the Near East where the seeds are mentioned in Hittite and Ancient Egyptian sources dating from more than 3,000 years ago as well as in the Hebrew Bible, or in the large Celtic Oppidum of Manching from La Tène Europe some 2,200 years ago. Dishes resembling ful medames are attested in the Jerusalem Talmud which was compiled before 400 AD.
In our time, the common vetch (''V. sativa'') has also risen to prominence. Together with broad bean cultivars such as horse bean or field bean, the FAO includes it among the 11 most important pulses in the world. It is grown – like tufted vetch (''V. cracca'') – as a mid-summer pollen source for honeybees, but the main usage of the common vetch is as forage for ruminant animals, both as fodder and legume. The bitter vetch, too, is grown extensively for this purpose, as are hairy vetch (''V. villosa'', also called fodder vetch), bard vetch (''V. articulata''), French vetch (''V. serratifolia'') and Narbon bean (''V. narbonensis''). ''V. benghalensis'' and Hungarian vetch (''V. pannonica'') are cultivated for forage and green manure.
The Hairy Vetch also has well-established uses as green manure and allelopathic cover crop. As regards the broad bean, it is known to accumulate aluminum in its tissue; in polluted soils it may be useful in phytoremediation, but with one permil of aluminum in the dry plant (possibly more in the seeds), it might not be edible anymore. The robust plants are useful as a beetle bank to provide habitat and shelter for carnivorous beetles and other arthropods to keep down pest invertebrates. When the root nodules of broad bean are inoculated with the rhodospirillacean bacterium ''Azospirillum brasilense'' and the glomeracean fungus ''Glomus clarum'', the species can also be productively grown in salty soils. In the 1980s, the auxin 4-Cl-IAA was studied in ''V. amurensis'' and the broad bean, and since 1990, the antibacterial γ-thionins fabatin-1 and -2 have been isolated from the latter species.
Despite a small chromosome count of ''n''=6, the broad bean has a high DNA content, making it easy for a micronucleus test of its root tips to recognize genotoxic compounds. A lectin from ''V. graminea'' is used to test for the medically significant N blood group.
