A lima bean (Phaseolus lunatus), also commonly known as: the butter bean, [2] sieva bean, [3] double bean [4] [5] or Madagascar bean is a legume grown for its edible seeds or beans.
Phaseolus lunatus is found in Meso- and South America. Two gene pools of cultivated lima beans point to independent domestication events. The Mesoamerican lima bean is distributed in neotropical lowlands, while the other is found in the western Andes. [6] They were discovered in Peru and may have been the first plant that was brought up under civilization by the native farmers. [7] [8]
The Andes domestication took place around 2000 BC [9] and produced a large-seeded variety (lima type), while the second, taking place in Mesoamerica around 800 AD, produced a small-seeded variety (Sieva type). [9] By around 1300, cultivation had spread north of the Rio Grande, and, in the 1500s, the plant began to be cultivated in the Old World. [9]
The small-seeded (Sieva) type is found distributed from Mexico to Argentina, generally below 1,600 m (5,200 ft) above sea level, while the large-seeded wild form (lima type) is found distributed in the north of Peru, from 320 to 2,030 m (1,050 to 6,660 ft) above sea level.
The Moche culture (1–800 CE) cultivated lima beans heavily and often depicted them in their art. [10] [ page needed ] During the Spanish Viceroyalty of Peru, lima beans were exported to the rest of the Americas and Europe, and since the boxes of such goods had their place of origin labeled "Lima, Peru", the beans got named as such. [8] Despite the origin of the name, when referring to the bean, the word "lima" is generally pronounced differently from the Peruvian capital. [11] [12]
The term "butter bean" is widely used in North and South Carolina for a large, flat and yellow/white variety of lima bean (P. lunatus var. macrocarpus, or P. limensis [13] ). In the United States Sieva-type beans are traditionally called butter beans, also otherwise known as the Dixie or Henderson type. In that area, lima beans and butter beans are seen as two distinct types of beans, although they are the same species. In the United Kingdom and the United States, "butter beans" refers to either dried beans which can be purchased to rehydrate, or the canned variety which are ready to use. In culinary use there, lima beans and butter beans are distinct, the former being small and green, the latter large and yellow. In areas where both are considered to be lima beans, the green variety may be labelled as "baby" (and less commonly "junior") limas.
In Spain, it is called garrofón, and constitutes one of the main ingredients of the famous Valencian paella .
In India, they are called double beans. Dried beans are soaked overnight and pressure-cooked as ingredients in curries.
The lima bean is a domesticated species of economic and cultural importance worldwide, especially in Mexico. The species has two varieties. The wild variety is silvester and the domesticated one is lunatus. [6]
In the U.S, it is a warm-season crop, grown mainly in Delaware and the mid-Atlantic region for processing and in the Midwest and California for dry beans. Baby lima beans are planted in early June and harvested about 10–12 weeks later. In western New York State, baby lima bean production increased greatly from 2011 to 2015. [14]
In Oaxaca, Mexico, the main rainy season lasts from June to August and most of the above-ground parts die during dry season. Germination or budding occurs in June or July. The first inflorescence is in October or November. The production of flowers and fruits usually ends between February and April. [15]
Both bush and pole (vine) cultivars exist; the latter range from 1 to 5 metres (3 ft 3 in to 16 ft 5 in) in height. The bush cultivars mature earlier than the pole cultivars. The pods are up to 15 cm (5.9 in) long. The mature seeds are 1 to 3 cm (0.39 to 1.18 in) long and oval to kidney-shaped. In most cultivars, the seeds are quite flat, but in the "potato" cultivars, the shape approaches spherical. White seeds are common, but black, red, orange, and variously mottled seeds are also known. The immature seeds are uniformly green. Lima beans typically yield 2,900 to 5,000 kg (6,400 to 11,000 lb) of seed and 3,000 to 8,000 kg (6,600 to 17,600 lb) of biomass per hectare.
The seeds of the cultivars listed below are white unless otherwise noted. Closely related or synonymous names are listed on the same line.
Phytophthora phaseoli is one example of a pathogen of the lima bean. It is an oomycete plant pathogen that causes downy mildew of lima bean during cool and humid weather conditions. To combat this pathogen, developing lima bean cultivars with resistance is a relatively cost-efficient method that is also environmentally safe as compared to using pesticides. [14]
Didymella is a foliar disease found in baby lima beans first reported in New York State. Symptoms include small necrotic tan spots with red to reddish brown irregular margins that come together to eventually cover the entire leaf. Lesions occur after around 3–4 weeks of planting and increase until there is considerable defoliation. Lesions are usually observed on the stems. Two pynidial fungi were found on leaves included Didymella sp. And Boeremia exigua var. exigua which is pathogenic on baby lima bean and plays a role in the foliar disease complex. Other fungal diseases on lima beans with similar symptoms are B. exigua var. exigua, pod blight caused by Diaporthe phaseolorum, and leaf spots caused by Phyllosticta sp. and Phomasubcircinata. [18]
The two-spotted spider mites [19] or Tetranychusurticae lay eggs on lima bean leaves. It prefers lima bean plants as a host food source over other plants such as tomato or cabbage plants. [20]
Spider mites pose the greatest threat to the lima bean plants as compared to other species such as the Common cutworm ( Spodoptera litura ) that are also known to feed on lima bean plants. They are host plants for their larvae. [19]
One herbivore of lima bean is Spodoptera littoralis , the African cotton leafworm. An attack by this herbivore induces hydrogen peroxide in the leaves. This may be also advantageous to defend against pathogens such as bacteria, fungi, or viruses, as they can easily invade herbivore-infected leaves. [21]
Other predatory insects include ants, wasps, flies [22] and beetles. [23]
Lima beans use extrafloral nectar (EFN) secretion when exposed to volatiles from other plants infested by herbivore species. Producing EFN can be an indirect defense since it supplies enemies of herbivores with an alternative food source. The predator of lima bean, spider mites, also have their own predators, the carnivorous mite Phytoseiulus persimilis. These predatory mites use EFN as an alternative food source and thus the production of this by the lima bean can attract P. persimilis and thus deter their herbivore hosts. [19]
The main induced defense of the lima bean is the Jasmonic acid pathway. Jasmonic acid induces production of extrafloral nectar flow or induces it when herbivory occurs such as when attacked by spider mites. [22]
One direct chemical defense involves cyanogenesis which is the release of hydrogen cyanide when the cell senses damage. Cyanide acts as a repellent on leaves of the lima bean. [23]
Phaseolus lunatus has adapted to live in many different climates around the world. [24] One of these adaptations includes a particularly effective induced herbivory defense. The lima bean is able to signal to the carnivorous natural enemy of herbivores, the carnivorous mite, mediated by HIPVs (Herbivore Induced Plant Volatiles) in an attempt to save itself from further predation. [25]
The lima bean plant does this as an induced defense when being eaten by herbivorous predators. It is the mechanical wounding and chemical elicitors from insect oral secretions that first begin the signaling pathway to induce HIPV production. [26] Once this pathway is induced, the plant produces HIPVs which are released in to the air and can be received by any organisms that have receptors capable of receiving HIPVs, which includes: carnivores, conspecific and heterospecific herbivores, as well as neighboring plants. [25] It is this signaling of the carnivorous natural enemy of herbivores that is of particular interest, as they become attracted to the plant and will then come and prey upon the plant's herbivorous enemy, thereby reducing herbivory of the plant. [27]
One particular experiment in which this was made apparent was in the understanding of the tritrophic system between the lima bean plant, two-spotted spider mite, and the carnivorous mite. [25] Here experimenters noticed an increase in HIPVs when the lima bean plant was preyed on by the two-spotted spider mite. [25] Then, when the carnivorous mite was introduced, it had increased prey searching efficacy and overall attraction to the lima bean plant, even once the two-spotted spider mite was removed, but the HIPVs remained high. [25]
Like many beans, raw lima beans are toxic (containing e.g. phytohaemagglutinin) if not boiled for at least 10 minutes. However, canned beans can be eaten without having to be boiled first, as they are pre-cooked. [28]
The lima bean can contain anti-nutrients like phytic acids, saponin, oxalate, tannin, and trypsin inhibitor. These inhibit absorption of nutrients in animals and can cause damage to some organs. In addition to boiling, methods of roasting, pressure cooking, soaking, and germination can also reduce the antinutrients significantly. [29]

The most abundant mineral in the raw lima bean is potassium, followed by calcium, phosphorus, magnesium, sodium, and iron. When lima beans germinate, there is increased bioavailability of calcium and phosphorus. [29] Additionally, it is a good source of vitamin B6. [30]
Lima beans, like many other legumes, are a good source of dietary fiber, and a virtually fat-free source of high-quality protein.
Lima beans contain both soluble fiber, which helps regulate blood sugar levels and lowers cholesterol, and insoluble fiber, which aids in the prevention of constipation, digestive disorders, irritable bowel syndrome, and diverticulitis.
The high fiber content in lima beans prevents blood sugar levels from rising too rapidly after eating them due to the presence of those large amounts of absorption-slowing compounds in the beans, and the high soluble fiber content. Soluble fiber absorbs water in the stomach, forming a gel that slows down the absorption of the bean's carbohydrates. They can therefore help balance blood sugar levels while providing steady, slow-burning energy, which makes them a good choice for people with diabetes suffering with insulin resistance.

A bean is the seed of several plants in the family Fabaceae, which are used as vegetables for human or animal food. They can be cooked in many different ways, including boiling, frying, and baking, and are used in many traditional dishes throughout the world.
A herbivore is an animal anatomically and physiologically adapted to eating plant material, for example foliage or marine algae, for the main component of its diet. As a result of their plant diet, herbivorous animals typically have mouthparts adapted to rasping or grinding. Horses and other herbivores have wide flat teeth that are adapted to grinding grass, tree bark, and other tough plant material.
The cucumber is a widely-cultivated creeping vine plant in the family Cucurbitaceae that bears cylindrical to spherical fruits, which are used as culinary vegetables. Considered an annual plant, there are three main types of cucumber—slicing, pickling, and seedless—within which several cultivars have been created. The cucumber originates in Asia extending from India, Nepal, Bangladesh, China, and Northern Thailand, but now grows on most continents, and many different types of cucumber are grown commercially and traded on the global market. In North America, the term wild cucumber refers to plants in the genera Echinocystis and Marah, though the two are not closely related.
Phaseolus is a genus of herbaceous to woody annual and perennial vines in the family Fabaceae containing about 70 plant species, all native to the Americas, primarily Mesoamerica.
A legume is a plant in the family Fabaceae, or the fruit or seed of such a plant. When used as a dry grain, the seed is also called a pulse. 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.
Phaseolus coccineus, known as runner bean, scarlet runner bean, or multiflora bean, is a plant in the legume family, Fabaceae. Another common name is butter bean, which, however, can also refer to the lima bean, a different species.
Phaseolus vulgaris, the common bean, is a herbaceous annual plant grown worldwide for its edible dry seeds or green, unripe pods. Its leaf is also occasionally used as a vegetable and the straw as fodder. Its botanical classification, along with other Phaseolus species, is as a member of the legume family Fabaceae. Like most members of this family, common beans acquire the nitrogen they require through an association with rhizobia, which are nitrogen-fixing bacteria.
Green beans are young, unripe fruits of various cultivars of the common bean, although immature or young pods of the runner bean, yardlong bean, and hyacinth bean are used in a similar way. Green beans are known by many common names, including French beans, string beans, and snap beans or simply "snaps." In the Philippines, they are also known as "Baguio beans" or "habichuelas" to distinguish them from yardlong beans.
An heirloom plant, heirloom variety, heritage fruit, or heirloom vegetable is an old cultivar of a plant used for food that is grown and maintained by gardeners and farmers, particularly in isolated communities of the Western world. These were commonly grown during earlier periods in human history, but are not used in modern large-scale agriculture.
The navy bean, haricot bean, pearl haricot bean, Boston bean, white pea bean, or pea bean is a variety of the common bean native to the Americas, where it was first domesticated. It is a dry white bean that is smaller than many other types of white beans, and has an oval, slightly flattened shape. It features in such dishes as baked beans, various soups such as Senate bean soup, and even pies.
Plant defense against herbivory or host-plant resistance (HPR) is a range of adaptations evolved by plants which improve their survival and reproduction by reducing the impact of herbivores. Plants can sense being touched, and they can use several strategies to defend against damage caused by herbivores. Many plants produce secondary metabolites, known as allelochemicals, that influence the behavior, growth, or survival of herbivores. These chemical defenses can act as repellents or toxins to herbivores or reduce plant digestibility. Another defensive strategy of plants is changing their attractiveness. To prevent overconsumption by large herbivores, plants alter their appearance by changing their size or quality, reducing the rate at which they are consumed.
Lotaustralin is a cyanogenic glucoside found in small amounts in Fabaceae austral trefoil, cassava, lima bean, roseroot and white clover, among other plants. Lotaustralin is the glucoside of methyl ethyl ketone cyanohydrin and is structurally related to linamarin, the acetone cyanohydrin glucoside also found in these plants. Both lotaustralin and linamarin may be hydrolyzed by the enzyme linamarase to form glucose and a precursor to the toxic compound hydrogen cyanide.
Guitarrero Cave is located in the Callejón de Huaylas valley in Yungay Province, in the Ancash region of Peru. The cave stands 50 m (160 ft) above the Santa River and 2,580 m (8,460 ft) meters above sea level.
(3S,6E)-nerolidol synthase (EC 4.2.3.48, (E)-nerolidol synthase, nerolidol synthase, (3S)-(E)-nerolidol synthase, FaNES1) is an enzyme with systematic name (2E,6E)-farnesyl-diphosphate diphosphate-lyase ((3S,6E)-nerolidol-forming). This enzyme catalyses the following chemical reaction
Tritrophic interactions in plant defense against herbivory describe the ecological impacts of three trophic levels on each other: the plant, the herbivore, and its natural enemies. They may also be called multitrophic interactions when further trophic levels, such as soil microbes, endophytes, or hyperparasitoids are considered. Tritrophic interactions join pollination and seed dispersal as vital biological functions which plants perform via cooperation with animals.
Vigna angularis, also known as the adzuki bean(Japanese: 小豆, azuki, Uncommon アヅキ, adzuki), azuki bean, aduki bean, red bean, or red mung bean, is an annual vine widely cultivated throughout East Asia for its small bean. The cultivars most familiar in East Asia have a uniform red color, but there are also white, black, gray, and variously mottled varieties.
Tecia solanivora, the Central American potato tuberworm, Guatemalan tuber moth, or Guatemalan potato moth, is a moth in the family Gelechiidae. It was described by Povolný in 1973. It is found from Guatemala, through Central America to South America, where it has been recorded from Colombia, Ecuador, Venezuela and Peru. It has also been introduced on the Canary Islands and mainland Spain.
Bacterial blight of soybean is a widespread disease of soybeans caused by Pseudomonas syringaepv. glycinea.
Phaseolus polystachios, also known as the thicket bean or wild kidney bean, is a perennial, herbaceous vine that is native to North America. It is unique among the Phaseolus in that its native range extends across the eastern temperate United States to southeast Canada, while most Phaseolus are tropical or subtropical. It is the namesake for the Polystachios group clade, which is the most species-rich within Phaseolus. In spite of its common name, it is more closely related to the lima bean, and it holds potential as a crop wild relative due to its resistance to white mold.
The Bolita bean is an heirloom variety of common bean endemic to New Mexico and southern Colorado. It is a small, round, and sweet bean that is traditional to New Mexican and southwestern cuisine.
