Vicia Serratifolia

''Vicia'' is a genus of over 240 species of flowering plants that are part of the legume family (Fabaceae), and which are commonly known as vetches. 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.

Bernard of Clairvaux shared a bread-of-vetch meal with his monks during the famine of 1124 to 1126, as an emblem of humility. However, Bitter Vetch largely was dropped from human use over time. It was only used to 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. However, broad beans remained prominent. In the Near East the seeds are mentioned in Hittite and Ancient Egyptian sources dating from more than 3,000 years ago as well as in the Christian Bible, and in the large Celtic Oppidum of Manching from the La Tène culture in 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. The main usage of the common vetch is as forage for ruminant animals, both as fodder and legume, but there are other uses, as tufted vetch, '' V. cracca'' is grown as a mid-summer pollen source for honeybees.

In 2017, global production of vetches was 920,537 tonnes. That year, 560,077 acreas were devoted to the cultivation of vetches in the world. Over 54% of that output came from Europe alone. Africa (17.8% of world total), Asia (15.6% of world total), Americas (10.6% of world total) and Oceania (1.8% of world total).[14

'' V. benghalensis'' and Hungarian vetch (''Vicia pannonica">V. pannonica'') are cultivated for forage and green manure">Vicia benghalensis">V. benghalensis'' and Hungarian vetch (''Vicia pannonica">V. pannonica'') are cultivated for forage and green manure.

The vetches also have a broad variety of other purposes. The Hairy Vetch has well-established uses as a green manure and as an allelopathic cover crop. As regards the broad bean, it is known to List of hyperaccumulators, accumulate aluminum in its tissue; in polluted soils it may be useful in phytoremediation, but with one per mil 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.

Toxicity

The vetches grown as forage are generally toxic to non-ruminants (such as humans), at least if eaten in quantity. Cattle and horses have been poisoned by ''V. villosa'' and ''V. benghalensis'', two species that contain canavanine in their seeds. Canavanine, a toxic analogue of the amino acid arginine, has been identified in Hairy Vetch as an appetite suppressant for monogastric animals, while Narbon bean contains the quicker-acting but weaker γ-glutamyl-S- ethenylcysteine. In common vetch, γ-glutamyl-β-cyanoalanine has been found. The active part of this molecule is β-cyanoalanine. It inhibits the conversion of the sulfur amino acid methionine to cysteine.

Cystathionine, an intermediary product of this biochemical pathway, is secreted in urine. This process can effectively lead to the depletion of vital protective reserves of the sulfur amino acid cysteine and thereby making ''Vicia sativa'' seed a dangerous component in mixture with other toxin sources. The Spanish pulse mix ' contains common vetch and bitter vetch in addition to vetchling ('' Lathyrus cicera'') seeds; it can be fed in small quantities to ruminants, but its use as a staple food will cause lathyrism even in these animals. Moreover, common vetch as well as broad bean – and probably other species of ''Vicia'' too – contain oxidants like convicine, isouramil, divicine and vicine in quantities sufficient to lower glutathione levels in G6PD-deficient persons to cause favism disease. At least broad beans also contain the lectin phytohemagglutinin and are somewhat poisonous if eaten raw. Split common vetch seeds resemble split red lentils (''Lens culinaris''), and has been occasionally mislabelled as such by exporters or importers to be sold for human consumption. In some countries where lentils are highly popular – e.g., Bangladesh, Egypt, India and Pakistan – import bans on suspect produce have been established to prevent these potentially harmful scams.

Ecology

Vetches have cylindrical root nodules of the indeterminate type and are thus nitrogen-fixing plants. Their flowers usually have white to purple or blue hues, but may be red or yellow; they are pollinated by bumblebees, honey bees, solitary bees and other insects.

''Vicia'' species are used as food plants by the caterpillars of some butterflies and moths, such as:

*''Coleophora cracella'' – only found on ''Vicia'' species
*''Coleophora fuscicornis'' – only found on smooth tare (''Vicia tetrasperma, V. tetrasperma'')
*''Paratalanta pandalis'' – recorded on bush vetch (''Vicia sepium, V. sepium'')
*''Chionodes lugubrella'' – recorded on tufted vetch ('' V. cracca'')
*Lime-speck pug (''Eupithecia centaureata'') – recorded on tufted vetch (''V. cracca'')
*Double-striped pug (''Gymnoscelis rufifasciata'') – recorded on broad bean ('' V. faba'')
*Provençal short-tailed blue (''Everes alcetas'')
*Amanda's blue (''Polyommatus amandus'') – only found on ''Vicia'' species
*Flame (moth), The flame (''Axylia putris'')
*Blackneck (''Lygephila pastinum'') – recorded on tufted vetch (''V. cracca'')

*''Colias'' species, e.g., Clouded sulphur (''C. philodice'')
*Leptidea sinapis, Wood white (''Leptidea sinapis'')
*Pea moth (''Cydia nigricana'')

Most other parasitism, parasites and plant pathogens affecting vetches have been recorded on the broad bean, the most widely cultivated and economically significant species. They include the mite ''Balaustium vignae'' whose adults are found on broad bean, the potexviruses Alternanthera mosaic virus, ''Alternanthera'' mosaic virus, clover yellow mosaic virus and white clover mosaic virus, and several other virus species such as Bidens mottle virus, ''Bidens'' mosaic virus, tobacco streak virus, Vicia cryptic virus, ''Vicia'' cryptic virus and Vicia faba endornavirus, ''Vicia faba'' endornavirus.

Etymology

''Vicia'' means 'binder' in Latin; this was the name used by Pliny the Elder, Pliny for vetch.Gledhill, David (2008). "The Names of Plants". Cambridge University Press. (hardback), (paperback). pp 401

The vetch is also referenced by Horace in his account of 'The town mouse and country mouse' as ''wikt:ervum#Latin, ervum.''Satires II.6, 117
/ref> This is said to be a source of comfort for the country mouse after a disturbing insight into urban life.
