Lupinus angustifolius | |
Lupinus angustifolius is a species of lupin known by many common names, including narrowleaf lupin, [1] narrow-leaved lupin [2] and blue lupin. It is native to Eurasia and northern Africa and naturalized in parts of Australia and North America. It has been cultivated for over 6000 years [3] as a food crop for its edible legume seeds, as a fodder for livestock and for green manure.
Like other legumes, the narrow-leaved lupin fixes nitrogen in a symbiotic interaction with different bacteria in the rhizosphere. Bacteria living in this rhizosphere include Bradyrhizobium lupinii or the newly discovered species Kribbella lupini. [4]
The narrow-leaved lupin is an erect, branching herb sometimes exceeding one meter. There are reduced-branching cultivars. Each palmate leaf is divided into 5 to 9 linear leaflets under 4 centimeters long. The herbage is slightly hairy in some areas. The inflorescence bears many flowers in shades of blue, violet, pink, or white. The fruit is a legume pod containing seeds of varying colors from dark gray to brown to white, or speckled or mottled. [5] Lupinus angustifolius has a high content of alkaloids, e.g. lupanin or angustifolin. However, cultivars with a low alkaloid content have been bred. These low alkaloid cultivars are called sweet lupins, such as the Australian Sweet Lupin. [6]
The narrow-leaved lupin is sown as early as possible in the spring, [7] to have the growing season as long as possible. Another reason for early sowing is its sensitivity to high temperature in spring. [8] Lupins react with a higher yield loss, when they are sown late, than other crops (e.g. cereals) do. [9] The optimum seed density depends on the site yield potential [10] and is generally higher in non-branching cultivars than in branching ones. [7] The variance is high, 14 to 138 plants per m2 [11] are an optimal plant density, depending on the yield potential of the site. On most grounds, a plant density around 80 plants per m2 would be the optimum.
Lupins are usually sown with technique used for cereals in a depth of about 5 cm.
The narrow-leaved lupin needs to be harvested as soon as the grain reaches a moisture of about 12%. The straw usually isn't ripened at this point, but further delay of harvest would increase losses from shattering of the pods and lodging. [12] The harvest is done with machinery used for cereals. Swathing is not widely applied. However, it can be a good alternative to reduce harvest losses in case harvest is delayed.
The disease and weed spectrum of the narrow-leaved lupin is different from most major crops and it is able to improve the soil (see Use). Therefore, it is a valuable partner in intensive crop rotations.
The plant is used as a green manure or as a grain legume for animal feed or human consumption. Through its ability to fix nitrogen and its low nutrient requirement this plant is suitable to be planted on exhausted fields as a soil improver. Additionally, lupins have strong roots, that can reduce the compaction of a soil. [13]
The whole plant, including the seeds, is widely used as a fodder for livestock, due to its high protein and energy content. Lupins contain high levels of fermentable carbohydrates and low levels of starch and are, therefore, an adequate ruminant feed. But lupins are a valuable feed for monogastric animals as well, because of the high digestibility of the lupin nitrogen and the low level of protease inhibitors. [14]
Lupins are mainly consumed as fermented foods, bread and pasta products, milk products or sprouts. As of 2020, only 4% of lupin were consumed by humans, with the majority used as stock feed. Lupin beans are growing in use as a plant-based protein source in the world marketplace. [15] [16] [6]
This species of lupin had its genome sequenced in May 2013. It was sequenced due to the interest in low alkaloid mutants as a food crop. L. angustifolius has a protein content of 35-40% in the seeds thus for providing protein to people of the world it is of high interest. Currently lupin is grown in Australia and sold under the name "Australian sweet lupin". The objective was to figure out how agronomic traits, low alkaloid traits, and protein content are manifested in the genome. The genome was sequenced in two cultivars, the poorly adapted tanjil and the better adapted unicrop. The genome was sequenced as such; whole genome shotgun sequencing dataset for this species with 26.9x (average amount of overlapping scaffolds) coverage of the genome, then NGS-based RAD-sequencing technology was used to obtain 8,244 sequence-defined markers. A total of 4,214 scaffolds from the genome sequence was assembled and aligned with the genetic map. [17]
Vicia sativa, known as the common vetch, garden vetch, tare or simply vetch, is a nitrogen-fixing leguminous plant in the family Fabaceae. It is now naturalised throughout the world occurring on every continent, except Antarctica and the Arctic. The centre of diversity is thought to be the Fertile Crescent, although gold standard molecular confirmation is currently not available.
Legumes are plants in the family Fabaceae, or the fruit or seeds of such plants. When used as a dry grain for human consumption, the seeds are also called pulses. Legumes are grown agriculturally, primarily for human consumption; for livestock forage and silage; and as soil-enhancing green manure. Well-known legumes include beans, soybeans, chickpeas, peanuts, lentils, lupins, grass peas, mesquite, carob, tamarind, alfalfa, and clover. Legumes produce a botanically unique type of fruit – a simple dry fruit that develops from a simple carpel and usually dehisces on two sides.
Lupinus polyphyllus, the large-leaved lupine, big-leaved lupine, many-leaved lupine, blue-pod lupine, or, primarily in cultivation, garden lupin, is a species of lupine (lupin) native to western North America from southern Alaska and British Columbia and western Wyoming, and south to Utah and California. It commonly grows along streams and creeks, preferring moist habitats.
Lupinus, commonly known as lupin, lupine, or regionally bluebonnet etc., is a genus of plants in the legume family Fabaceae. The genus includes over 199 species, with centers of diversity in North and South America. Smaller centers occur in North Africa and the Mediterranean. They are widely cultivated, both as a food source and as ornamental plants, but are invasive to some areas.
Crotalaria is a genus of flowering plants in the family Fabaceae commonly known as rattlepods. The genus includes over 700 species of herbaceous plants and shrubs. Africa is the continent with the majority of Crotalaria species, which are mainly found in damp grassland, especially in floodplains, depressions and along edges of swamps and rivers, but also in deciduous bush land, roadsides and fields. Some species of Crotalaria are grown as ornamentals. The common name rattlepod or rattlebox is derived from the fact that the seeds become loose in the pod as they mature, and rattle when the pod is shaken. The name derives from the Ancient Greek κρόταλον, meaning "castanet", and is the same root as the name for the rattlesnakes (Crotalus).
Medicago truncatula, the barrelclover, strong-spined medick, barrel medic, or barrel medick, is a small annual legume native to the Mediterranean region that is used in genomic research. It is a low-growing, clover-like plant 10–60 centimetres (3.9–23.6 in) tall with trifoliate leaves. Each leaflet is rounded, 1–2 centimetres (0.39–0.79 in) long, often with a dark spot in the center. The flowers are yellow, produced singly or in a small inflorescence of two to five together; the fruit is a small, spiny pod.
Nelumbo nucifera, also known as sacred lotus, Indian lotus, or simply lotus, is one of two extant species of aquatic plant in the family Nelumbonaceae. It is sometimes colloquially called a water lily, though this more often refers to members of the family Nymphaeaceae.
Vigna aconitifolia is a drought-resistant legume, commonly grown in arid and semi-arid regions of India. It is commonly called mat bean, moth bean, matki or dew bean. The pods, sprouts and protein-rich seeds of this crop are commonly consumed in India. Moth bean can be grown on many soil types, and can also act as a pasture legume.
Lupinus mutabilis is a species of lupin grown in the Andes, mainly for its edible bean. Vernacular names include tarwi, chocho, altramuz, Andean lupin, South American lupin, Peruvian field lupin, and pearl lupin. Its nutrient-rich seeds are high in protein, as well as a good source for cooking oil. However, their bitter taste has made L. mutabilis relatively unknown outside the Andes, though modern technology makes it easier to remove the bitter alkaloids. Like other species of lupin beans, it is expanding in use as a plant-based protein source.
Lupin or lupini are the yellow legume seeds of the genus Lupinus. They are traditionally eaten as a pickled snack food, primarily in the Mediterranean basin, Latin America and North Africa. The most ancient evidence of lupin is from ancient Egypt, dating back to the 22nd century BC. The bitter variety of the beans are high in alkaloids and are extremely bitter unless rinsed methodically. Low alkaloid cultivars called sweet lupins have been bred, and are increasingly planted.
Lupinus albus, commonly known as the white lupin or field lupine, is a member of the genus Lupinus in the family Fabaceae. It is a traditional pulse cultivated in the Mediterranean region.
Lupinus luteus is known as annual yellow-lupin, European yellow lupin or yellow lupin. It is native to the Mediterranean region of Southern Europe.
An apple is a round, edible fruit produced by an apple tree. Apple trees are cultivated worldwide and are the most widely grown species in the genus Malus. The tree originated in Central Asia, where its wild ancestor, Malus sieversii, is still found. Apples have been grown for thousands of years in Asia and Europe and were introduced to North America by European colonists. Apples have religious and mythological significance in many cultures, including Norse, Greek, and European Christian tradition.
Erythrina edulis (basul) is a nitrogen fixing tree that is native to the Andean region from western Venezuela to southern Bolivia. Nowadays it is known in Venezuela as "frijol mompás", in Bolivia, Peru and Northwest Argentina as "psonay", "pajuro", "sachaporoto del basul" or "poroto del sacha", in Colombia as "chachafruto", "balú", "baluy" or "sachaporoto" and in Ecuador as "guato". Although it is widely known, it is not commonly cultivated. Future research is needed, especially in agroforestry. Basul is a legume and so it produces protein-rich beans covered in pods which can be used for human or animal nutrition. The leaves and branches can be used as fodder. Besides the agricultural aspects, Erythrina edulis can also be used as a fence plant.
The Legume Information System (LIS) is legume sciences portal specifically for legume breeders and researchers, established and supported by the Agricultural Research Service of the United States Department of Agriculture. The mission of the Legume Information System is "to facilitate discoveries and crop improvement in the legumes," in particular to improve crop yields, their nutritional value, and our understanding of basic legume science.
Lupinus sericeus is a species of flowering plant in the legume family known by the common name silky lupine or Pursh's silky lupine. It is native to western North America from British Columbia to Arizona and east to Alberta and Colorado.
Genisteae is a tribe of trees, shrubs and herbaceous plants in the subfamily Faboideae of the family Fabaceae. It includes a number of well-known plants including broom, lupine (lupin), gorse and laburnum.
George Darvel Hill was a New Zealand agronomist, naval reservist, and a justice of the peace and unionist.
Anagyrine is a teratogenic alkaloid first isolated from Anagyris foetida in the year 1885 by French biologists Hardy and Gallois. A. foetida, the Stinking Bean Trefoil, is a highly toxic shrub native to the Mediterranean region, with a long history of use in folk medicine. In the year 1939 Anagyrine was found by James Fitton Couch to be identical to an alkaloid present in many species belonging to the plant genus Lupinus (lupins). The toxin can cause crooked calf disease if a cow ingests the plant during certain periods of pregnancy.
Quinolizidine alkaloids are natural products that have a quinolizidine structure; this includes the lupine alkaloids.
