Hydnora
''Hydnora'' is a group of parasitic plants described as a genus in 1775. It is native to Africa, Madagascar, and the Arabian Peninsula. Hydnora pollinates through brood-site mimicry. This is a method of pollination in which the plant emits a smell that is attractive to insects, so that the plant can trap the insect and allow to take pollen so that it can pollinate other Hydnora. Taxonomy The following species are listed within the genus ''Hydnora'': # ''Hydnora abyssinica'' A.Br. - Oman, Yemen, Saudi Arabia; S + C + SE + E Africa from Eritrea + Sudan to Namibia + KwaZulu-Natal # ''Hydnora africana'' Thunb. - Angola, Namibia, Cape Province #''Hydnora arabica'' Bolin & Musselman - Oman & Yemen # ''Hydnora esculenta'' Jum. & H.Perrier - Madagascar # ''Hydnora sinandevu'' Beentje & Q.Luke - Kenya, Tanzania # ''Hydnora triceps'' Drège & E.Mey. - Northern Cape Province, Namibia # '' Hydnora visseri'' Bolin, E.Maass, & Musselman - Northern Cape Province, Namibia Etymology The genus ...

Hydnora Africana
''Hydnora africana'' is an achlorophyllous plant in the subfamily Hydnoroideae, native to southern Africa that is parasitic on the roots of members of the family Euphorbiaceae. It is also called ''jakkalskos'' or ''jackal food''. The specific epithet ''africana'' means to be from Africa. Molecular data has suggested that Hydnoroideae is a " basal angiosperm" solidifying its place among the more primitive flowering plants. ''Hydnoraceae'' are the only angiosperms known to have no leaves or scales and are considered obligate parasites, completely dependent on their hosts to survive. The plant grows underground, except for a fleshy flower that emerges above ground and emits an odor of feces to attract its natural pollinators, dung beetles and carrion beetles. The vegetative body of the plants has been reduced to only consisting of roots and flowers. The flowers act as temporary traps, retaining the beetles that enter long enough for them to pick up pollen. Description Morph ...

Hydnora Visseri
''Hydnora visseri'', the Visser's hydnora, is a subterranean holoparasitic plant, lacking leaves and roots, and is described from southwestern Namibia and northwestern South Africa and has the longest tepal lobes of all ''Hydnora'' species. The genus ''Hydnora'' is composed entirely of holoparasitic plants that attach to the root of their hosts and are restricted to Africa and southwestern Asia. Description ''Hydnora visseri'', as a holoparasitic plant, lacks chlorophyll and depends entirely on its hosts, '' Euphorbia gregaria'' or ''E. gummifera'', for all water and nutrition. ''H. visseri'' lacks leaves and roots. The vegetative body of the plant is a brown warty rhizome that spreads laterally through the soil. The bumps on the rhizome of ''Hydnora'' spp. can differentiate into haustoria (specialized organs for parasitizing the host plant), flower buds, or bifurcations of the rhizome. The rhizomes when broken are reddish to pink and contain high levels of tannins. The only ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydnora Triceps
''Hydnora triceps'' is a holoparasitic flowering plant native to Africa that grows on the roots of '' Euphorbia dregeana''. Completely lacking in chlorophyll, it depends on its host for water and nutrients. The plant structure is composed of only specialized stems, buds, and haustoria, lacking any leaf-like structures entirely. It spends its life underground and only emerges to flower. Taxonomy German botanist Johann Franz Drège described ''Hydnora triceps'' in 1830 after collecting it from the Northwestern Cape. It was then thought extinct for many years until rediscovered by botanist Johann Visser in 1988. It is one of four species of parasitic underground plants in the genus '' Hydnora''. Distribution ''Hydnora triceps'' is found only in the northwestern Cape and southern Namibia. Additionally, since it is entirely dependent on '' Euphorbia dregeana'', which also seems to be its exclusive host, it is only found in association with this plant. About 10% of all the ''Euphorbi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parasitic Plant
A parasitic plant is a plant that derives some or all of its nutritional requirements from another living plant. They make up about 1% of angiosperms and are found in almost every biome. All parasitic plants develop a specialized organ called the haustorium, which penetrates the host plant, connecting them to the host vasculature – either the xylem, phloem, or both. For example, plants like ''Striga'' or ''Rhinanthus'' connect only to the xylem, via xylem bridges (xylem-feeding). Alternately, plants like ''Cuscuta'' and some members of ''Orobanche'' connect to both the xylem and phloem of the host. This provides them with the ability to extract water and nutrients from the host. Parasitic plants are classified depending on the location where the parasitic plant latches onto the host (root or stem), the amount of nutrients it requires, and their photosynthetic capability. Some parasitic plants can locate their host plants by detecting volatile chemicals in the air or soil give ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plastid Genome
Chloroplast DNA (cpDNA) is the DNA located in chloroplasts, which are photosynthetic organelles located within the cells of some eukaryotic organisms. Chloroplasts, like other types of plastid, contain a genome separate from that in the cell nucleus. The existence of chloroplast DNA was identified biochemically in 1959, and confirmed by electron microscopy in 1962. The discoveries that the chloroplast contains ribosomes and performs protein synthesis revealed that the chloroplast is genetically semi-autonomous. The first complete chloroplast genome sequences were published in 1986, ''Nicotiana tabacum'' (tobacco) by Sugiura and colleagues and ''Marchantia polymorpha'' (liverwort) by Ozeki et al. Since then, a great number of chloroplast DNAs from various species have been sequenced. Molecular structure Chloroplast DNAs are circular, and are typically 120,000–170,000 base pairs long. They can have a contour length of around 30–60 micrometers, and have a mass of about 80– ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Truffle
A truffle is the fruiting body of a subterranean ascomycete fungus, predominantly one of the many species of the genus ''Tuber''. In addition to ''Tuber'', many other genera of fungi are classified as truffles including '' Geopora'', '' Peziza'', '' Choiromyces'', '' Leucangium'', and over a hundred others. These genera belong to the class Pezizomycetes and the Pezizales order. Several truffle-like basidiomycetes are excluded from Pezizales, including ''Rhizopogon'' and ''Glomus''. Truffles are ectomycorrhizal fungi, so they are usually found in close association with tree roots. Spore dispersal is accomplished through fungivores, animals that eat fungi. These fungi have significant ecological roles in nutrient cycling and drought tolerance. Some truffle species are highly prized as food. French gastronome Jean Anthelme Brillat-Savarin called truffles "the diamond of the kitchen". Edible truffles are used in Italian, French and numerous other national . Truffles are ...
