Brassicaceae or Cruciferae is a medium-sized and economically important family of flowering plants commonly known as the mustards, the crucifers, or the cabbage family. Most are herbaceous plants, while some are shrubs. The leaves are simple, lack stipules, and appear alternately on stems or in rosettes. The inflorescences are terminal and lack bracts. The flowers have four free sepals, four free alternating petals, two shorter free stamens and four longer free stamens. The fruit has seeds in rows, divided by a thin wall.
Cabbage, comprising several cultivars of Brassica oleracea, is a leafy green, red (purple), or white biennial plant grown as an annual vegetable crop for its dense-leaved heads. It is descended from the wild cabbage, and belongs to the "cole crops" or brassicas, meaning it is closely related to broccoli and cauliflower ; Brussels sprouts ; and Savoy cabbage.
Brassica is a genus of plants in the cabbage and mustard family (Brassicaceae). The members of the genus are informally known as cruciferous vegetables, cabbages, mustard plants, or simply brassicas. Crops from this genus are sometimes called cole crops—derived from the Latin caulis, denoting the stem or stalk of a plant.
Rutabaga or swede is a root vegetable, a form of Brassica napus. Other names include Swedish turnip, neep (Scots), and turnip. However, elsewhere, the name "turnip" usually refers to the related white turnip. The species Brassica napus originated as a hybrid between the cabbage and the turnip. Rutabaga roots are eaten as human food in various ways, and the leaves can be eaten as a leaf vegetable. The roots and tops are also used for livestock, fed directly in the winter or foraged in the field during the other seasons. Scotland, Northern and Western England, Wales, the Isle of Man, and Ireland had a tradition of carving the roots into Jack-o'-lanterns at Halloween.
Rapeseed, also known as rape and oilseed rape, is a bright-yellow flowering member of the family Brassicaceae, cultivated mainly for its oil-rich seed, which naturally contains appreciable amounts of erucic acid. The term "canola" denotes a group of rapeseed cultivars that were bred to have very low levels of erucic acid and which are especially prized for use as human and animal food. Rapeseed is the third-largest source of vegetable oil and the second-largest source of protein meal in the world.
Mustard oil can mean either the pressed oil used for cooking, or a pungent essential oil also known as volatile oil of mustard. The essential oil results from grinding mustard seed, mixing the grounds with water, and isolating the resulting volatile oil by distillation. It can also be produced by dry distillation of the seed. Pressed mustard oil is used as cooking oil in some cultures, but sale is restricted in some countries due to high levels of erucic acid. Varieties of mustard seed low in erucic acid have been cultivated.
The triangle of U is a theory about the evolution and relationships among the six most commonly known members of the plant genus Brassica. The theory states that the genomes of three ancestral diploid species of Brassica combined to create three common tetraploid vegetables and oilseed crop species. It has since been confirmed by studies of DNA and proteins.
Brassica rapa is a plant species that has been widely cultivated into many forms, including the turnip, komatsuna, napa cabbage, bomdong, bok choy, and rapini.
Camelina sativa is a flowering plant in the family Brassicaceae usually known as camelina, gold-of-pleasure, or false flax, but also occasionally as wild flax, linseed dodder, German sesame, or Siberian oilseed. It is native to Europe and areas of Central Asia, but cultivated as an oilseed crop mainly in Europe and in North America. It is not related to true flax, in the family Linaceae.
The mustard plant is any one of several plant species in the genera Brassica, Rhamphospermum and Sinapis in the family Brassicaceae. Mustard seed is used as a spice. Grinding and mixing the seeds with water, vinegar, or other liquids creates the yellow condiment known as prepared mustard. The seeds can also be pressed to make mustard oil, and the edible leaves can be eaten as mustard greens. Many vegetables are cultivated varieties of mustard plants; domestication may have begun 6,000 years ago.
Brassica juncea, commonly brown mustard, Chinese mustard, Indian mustard, Korean green mustard, leaf mustard, Oriental mustard and vegetable mustard, is a species of mustard plant.
Crambe abyssinica is an annual oilseed crop of the family Brassicaceae. It is mainly cultivated due to the high levels of erucic acid that are contained in its seeds. The crambe oil is used for industrial purposes and its side products can be partly used as animal feed.
Cruciferous vegetables are vegetables of the family Brassicaceae with many genera, species, and cultivars being raised for food production such as cauliflower, cabbage, kale, garden cress, bok choy, broccoli, Brussels sprouts, mustard plant and similar green leaf vegetables. The family takes its alternative name from the shape of their flowers, whose four petals resemble a cross.
Thlaspi arvense, known by the common name field pennycress, is a flowering plant in the cabbage family Brassicaceae. It is native to Eurasia, and is a common weed throughout much of North America and its home.
Leptosphaeria maculans is a fungal pathogen of the phylum Ascomycota that is the causal agent of blackleg disease on Brassica crops. Its genome has been sequenced, and L. maculans is a well-studied model phytopathogenic fungus. Symptoms of blackleg generally include basal stem cankers, small grey lesions on leaves, and root rot. The major yield loss is due to stem canker. The fungus is dispersed by the wind as ascospores or rain splash in the case of the conidia. L. maculans grows best in wet conditions and a temperature range of 5–20 degrees Celsius. Rotation of crops, removal of stubble, application of fungicide, and crop resistance are all used to manage blackleg. The fungus is an important pathogen of Brassica napus (canola) crops.
Myrosinase is a family of enzymes involved in plant defense against herbivores, specifically the mustard oil bomb. The three-dimensional structure has been elucidated and is available in the PDB.
Diplotaxis tenuifolia is a species of flowering plant in the mustard family known by the common name perennial wall-rocket. It is native to Europe and western Asia, where it grows on disturbed ground and roadsides, and it can now be found throughout much of the temperate world where it has naturalized. In recent years it has increasingly been cultivated to produce salad leaves, which are marketed as wild rocket in Britain or arugula in the US. It is easily confused with garden rocket, which has similar uses.
Brassica elongata, the elongated mustard or long-stalked rape, is a species of the mustard plant that is native to parts of Central Europe, Eastern Europe, the Balkan Peninsula, the Caucasus, Morocco and parts of Central Asia. Through plant invasion this species has become naturalized in many other parts of the world. Some of these naturalized regions include South Africa, North Western Europe, Australia and North America. Given the wide range of climate and ecological conditions of these regions, B. elongata has been able to disrupt the ecosystems of their native plant habitats and has been label as an invasive species in many of its naturalized zones. In North America, this species is often found as a roadside weed in the southwestern states, particularly in the state of Nevada. Studies allude that the Cruciferae might have migrated through the Bering land bridge from what is now Central Asia. Commonly known as the long-stalked rape or as langtraubiger Kohl in German, this species is a close cousin to Brassica napus (rapeseed) and a secondary genetic relative to B. oleracea (kale). As a close genetic species of the rapeseed, the long-stalked rape has one of the highest counts of accumulated polyunsaturated linoleic and linolenic acid. Both compounds are heavily used to manufacture vegetable oils. Brassica elongata has the propagative potential of turning into a horticultural product from what is currently a noxious weed.
Psylliodes chrysocephala or Psylliodes chrysocephalus, commonly known as the cabbage-stem flea beetle, is a species of leaf beetle situated in the subfamily Galerucinae and the tribe Alticini.
Rapeseed oil is one of the oldest known vegetable oils. There are both edible and industrial forms produced from rapeseed, the seed of several cultivars of the plant family Brassicaceae. Historically, it was restricted as a food oil due to its content of erucic acid, which in laboratory studies was shown to be damaging to the cardiac muscle of laboratory animals in high quantities and which imparts a bitter taste, and glucosinolates, which made many parts of the plant less nutritious in animal feed. Rapeseed oil from standard cultivars can contain up to 54% erucic acid.
