Daucus is a worldwide genus of herbaceous plants of the celery family Apiaceae of which the best-known species is the cultivated carrot. Daucus has about 75 species. [1] The oldest carrot fossil is 1.3 Ma, and was found on the island of Madeira in the Atlantic Ocean. [2]
Members of Daucus are distinguished within the family Apiaceae by their leaves which are 2–3 pinnatisect with narrow end sections. The genus primarily consists of biennial plants but also includes some annual plants and some perennial herbs. All Daucus have bristly stems. The inflorescences are umbels. The flowers are mostly white, with bracts and bracteoles. The petals may be pure white, reddish, pinkish or yellowish. They are emarginate above and have pointed, wrapped lobules. The petals are often unequal in size, with petals at the outermost edge of the inflorescence often being larger. The fruit is an ovoid to ellipsoidal schizocarp, cylindrical or compressed, with ciliate primary ribs and secondary ribs with a row of hooked spines. [3] Some species have a small pale or white edible taproot, similar to a radish, which may or may not be bitter in taste.
Daucus pollination is carried out by insects, primarily: Lepidoptera, Coleoptera, Diptera, and Hymenoptera. It is a cosmopolitan genus with endemic species on most continents as well as on many islands and in isolated areas.[ citation needed ] The genus centre is in North Africa and Southwest Asia in the Temperate Zone.[ citation needed ] Prolonged dry or cold weather tends to retard growth in Daucus species, but the genus as a whole is evolutionarily adaptative to these conditions.[ citation needed ] Some Daucus species accumulate substantial resources in large underground taproots without impeding plant development.[ citation needed ] Native to Europe is the carrot, with two subspecies: wild carrot and (subsp carota Daucus carota), a cultivated form of carrot, also called garden carrot.
Four members of the Daucus genus were examined to determine differences in isoenzyme patterns and plastid DNA. The four were: Daucus carota subspecies sativus cultivar Danvers, D. carota subsp. gummifer, D. capillifolius, and D. pusillus. Although only one form of HSDH (homoserine dehydrogenase) was present in each Daucus line, the rate of migration of HSDH from cv. Danvers was different from that of the others. Multiple isoenzymic forms of ADH were present in each Daucus cultivar. Comparison of endonuclease restriction fragment patterns from plastid DNAs digested by BamHI revealed only small differences between plastid DNAs of cv. Danvers and subsp. gummifer, whereas large differences were observed between cv. Danvers and D. pusillus plastid DNA patterns. No differences were found between cv. Danvers and D. capillifolius plastid DNA patterns when examined using eight different restriction enzymes. The data indicate that specific isoenzyme and organelle DNA restriction fragment patterns will be useful markers for precise identification of genomes of different Daucus species. [4]
The genus comprises about 75 species, [1] including:
Daucus has an OPALS allergy scale rating of 10 out of 10, indicating extremely high potential to cause allergic reactions. [5]
Apiaceae or Umbelliferae is a family of mostly aromatic flowering plants named after the type genus Apium and commonly known as the celery, carrot or parsley family, or simply as umbellifers. It is the 16th-largest family of flowering plants, with more than 3,800 species in about 446 genera, including such well-known and economically important plants as ajwain, angelica, anise, asafoetida, caraway, carrot, celery, chervil, coriander, cumin, dill, fennel, lovage, cow parsley, parsley, parsnip and sea holly, as well as silphium, a plant whose identity is unclear and which may be extinct.
Fuchsia is a genus of flowering plants that consists mostly of shrubs or small trees.
Daucus carota, whose common names include wild carrot, European wild carrot, bird's nest, bishop's lace, and Queen Anne's lace, is a flowering plant in the family Apiaceae. It is native to temperate regions of the Old World and was naturalized in the New World.
Cyclamen is a genus of 23 species of perennial flowering plants in the family Primulaceae. In English, it is known by the common names sowbread or swinebread. Cyclamen species are native to Europe and the Mediterranean Basin east to the Caucasus and Iran, with one species in Somalia. They grow from tubers and are valued for their flowers with upswept petals and variably patterned leaves.
Chromoplasts are plastids, heterogeneous organelles responsible for pigment synthesis and storage in specific photosynthetic eukaryotes. It is thought that like all other plastids including chloroplasts and leucoplasts they are descended from symbiotic prokaryotes.
Anthriscus sylvestris, known as cow parsley, wild chervil, wild beaked parsley, Queen Anne's lace or keck, is a herbaceous biennial or short-lived perennial plant in the family Apiaceae (Umbelliferae), genus Anthriscus. It is also sometimes called mother-die, a name that is also applied to the common hawthorn. It is native to Europe, western Asia and northwestern Africa. It is related to other diverse members of Apiaceae, such as parsley, carrot, hemlock and hogweed. It is often confused with Daucus carota, another member of the Apiaceae also known as "Queen Anne's lace" or "wild carrot".
Osteospermum moniliferum is an evergreen flowering shrub or small tree in the daisy family, Asteraceae. It is native to southern Africa, ranging through South Africa and Lesotho to Mozambique and Zimbabwe.
The carrot is a root vegetable, typically orange in color, though heirloom variants including purple, black, red, white, and yellow cultivars exist, all of which are domesticated forms of the wild carrot, Daucus carota, native to Europe and Southwestern Asia. The plant probably originated in Persia and was originally cultivated for its leaves and seeds. The most commonly eaten part of the plant is the taproot, although the stems and leaves are also eaten. The domestic carrot has been selectively bred for its enlarged, more palatable, less woody-textured taproot.
Erigenia bulbosa, also known as harbinger of spring or pepper and salt, is a flowering perennial plant in the family Apiaceae. E. bulbosa is the only species in the genus Erigenia and tribe Erigenieae. This plant is known as harbinger of spring because it is one of the earliest blooming native wildflowers of rich forests in the mid-latitude United States. Throughout most of its range it blooms from late February through early April.
Asplenium trichomanes, the maidenhair spleenwort, is a small fern in the spleenwort genus Asplenium. It is a widespread and common species, occurring almost worldwide in a variety of rocky habitats. It is a variable fern with several subspecies.
Somatic embryogenesis is an artificial process in which a plant or embryo is derived from a single somatic cell. Somatic embryos are formed from plant cells that are not normally involved in the development of embryos, i.e. ordinary plant tissue. No endosperm or seed coat is formed around a somatic embryo.
Allium siculum, known as honey garlic, Sicilian honey lily, Sicilian honey garlic, or Mediterranean bells, is a European and Turkish species of plant in the genus Allium. It is native to the regions around the Mediterranean and Black Seas, and grown in other regions as an ornamental and as a culinary herb.
Dactylorhiza majalis subsp. traunsteinerioides, known as the narrow-leaved marsh-orchid and Pugsley's marsh orchid, is a subspecies of Dactylorhiza majalis found only in Britain and Ireland. It is also treated as the species Dactylorhiza traunsteinerioides.
Daucus edulis is a critically endangered species of flowering plant in the celery family Apiaceae. It is endemic to Madeira.
Ferula assa-foetida is a species of Ferula endemic to Southern Iran. It is a source of asafoetida, but not the main source, although many sources claim so. The production of asafoetida from this species is confined to Southern Iran, especially the area near Lar.
Dudleya cymosasubsp. pumila, most commonly known as the low canyon dudleya, chalky canyon dudleya or California live-forever, is a species of perennial succulent plant. It has diamond to spoon shaped leaves, sometimes coated with a fine white powder, and in May through July, bright red, orange or yellow flowers adorn the short inflorescence. A leaf succulent primarily found growing in rocky cliffs and slopes, it is endemic to California, and grows in the Transverse Ranges and South Coast Ranges, with some outlying populations. A variable plant, in some localities it is difficult to distinguish from other plants in the genus.
Lupinus caudatus is a widespread species of wildflower in genus Lupinus from western North America known by the common names tailcup lupin and spurred lupin. It is distinctive for the short spur on its purple-blue flowers, for which it is named. Because of its wide distribution and toxicity it commonly causes poisonings of susceptible livestock such as horses, cattle, and sheep, though it is eaten without harm by wild herbivores like deer and elk. It is generally found from the Coastal Ranges and Sierra Nevada Mountains in the west to the Rocky Mountains in the east.
