Actaea (plant)
''Actaea'', commonly called baneberry, bugbane and cohosh, is a genus of flowering plants of the family Ranunculaceae, native to subtropical, temperate and subarctic regions of Europe, Asia and North America. Taxonomy The genus was redefined to include ''Cimicifuga'' and '' Souliea'' in the 1990s (Compton et al. 1998, Compton & Culham 2002, Gao et al. 2006, RHS Plant Finder, 2007) based on combined evidence from DNA sequence data, similarity in biochemical constituents and on morphology returning it to the original Linnean concept of the genus. The number of species in ''Actaea'' is to 25–30 using this concept. Other botanists (e.g., Hoffman 1999, Wang et al. 1999, Lee & Park 2004, Wang et al. 2009) reject this merger because only one group (''Actaea'') have fleshy fruit while the remainder have dry fruit. However, this narrower generic concept works for only a single morphological character and other characters such as number of carpels moves the generic boundary. The genu ...

Flowering Plant Families Of The World
A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Angiospermae). The biological function of a flower is to facilitate reproduction, usually by providing a mechanism for the union of sperm with eggs. Flowers may facilitate outcrossing (fusion of sperm and eggs from different individuals in a population) resulting from cross-pollination or allow selfing (fusion of sperm and egg from the same flower) when self-pollination occurs. There are two types of pollination: self-pollination and cross-pollination. Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Cross-pollination is when pollen is transferred from the anther of one flower to the stigma of another flower on a different individual of the same species. Self-pollination happens in flowers where the stamen and carpel mature at the same time, and are positioned ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vernon Heywood
Vernon Hilton Heywood (born 24 December 1927 - died 2022) was a British biologist. He specialised in medicinal and aromatic plants, and the conservation of wild relatives of plants. Heywood was appointed as lecturer at University of Liverpool, UK in 1955, promoted to senior lecturer in 1960 and to reader in 1963. He was awarded the second established Chair in Botany in 1964 and left Liverpool in 1968. He was Professor of Botany and Head of Department at the University of Reading until 1987 when he became founder and director of Botanic Gardens Conservation International (BGCI). In 1987 he was awarded the Linnean Medal of the Linnean Society of London. Planta Europa honored him with their Linnaeus award at their fifth conference, held in 2007 in Cluj Napoca. The book ''Taxonomy and Plant Conservation'' (Cambridge University Press, 2006, Etelka Leadlay and Stephen Jury, eds.) was dedicated as a tribute to Heywood in honor of his 75th birthday.

Fusarium
''Fusarium'' is a large genus of filamentous fungi, part of a group often referred to as hyphomycetes, widely distributed in soil and associated with plants. Most species are harmless saprobes, and are relatively abundant members of the soil microbial community. Some species produce mycotoxins in cereal crops that can affect human and animal health if they enter the food chain. The main toxins produced by these ''Fusarium'' species are fumonisins and trichothecenes. Despite most species apparently being harmless (some existing on the skin as commensal members of the skin flora), some ''Fusarium'' species and subspecific groups are among the most important fungal pathogens of plants and animals. The name of ''Fusarium'' comes from Latin ''fusus'', meaning a spindle. Taxonomy The taxonomy of the genus is complex. A number of different schemes have been used, and up to 1,000 species have been identified at times, with approaches varying between wide and narrow concepts ...

Easter Island
Easter Island ( rap, Rapa Nui; es, Isla de Pascua) is an island and special territory of Chile in the southeastern Pacific Ocean, at the southeasternmost point of the Polynesian Triangle in Oceania. The island is most famous for its nearly 1,000 extant monumental statues, called '' moai'', which were created by the early Rapa Nui people. In 1995, UNESCO named Easter Island a World Heritage Site, with much of the island protected within Rapa Nui National Park. Experts disagree on when the island's Polynesian inhabitants first reached the island. While many in the research community cited evidence that they arrived around the year 800, there is compelling evidence presented in a 2007 study that places their arrival closer to 1200. The inhabitants created a thriving and industrious culture, as evidenced by the island's numerous enormous stone ''moai'' and other artifacts. However, land clearing for cultivation and the introduction of the Polynesian rat led to gradual defo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Toromiro
''Sophora toromiro'', commonly known as toromiro, is a species of flowering tree in the legume family, Fabaceae, that is endemic to Easter Island. History Heavy deforestation had eliminated most of the island's forests by the first half of the 17th century, and the once common toromiro became rare and ultimately extinct in the wild in the 1960s. Local tradition has it that the rongorongo tablets of Easter Island are made of toromiro. However, all tablets of native wood tested by modern methods have turned out to be ''Thespesia populnea'', known as ''miro'' or ''milo'' in some Polynesian languages. David Attenborough describes the timber from which a small wooden male sculpture in his possession is made, having been identified by Kew Gardens as ''Sophora toromiro''. Conservation The tree is being reintroduced to the island in a scientific project partly led jointly by the Royal Botanic Gardens, Kew and the Gothenburg Botanical Garden, where the only remaining plants of this s ...

Molecular Marker
A molecular marker is a molecule, sampled from some source, that gives information about its source. For example, DNA is a molecular marker that gives information about the organism from which it was taken. For another example, some proteins can be molecular markers of Alzheimer's disease in a person from which they are taken. Molecular markers may be non-biological. Non-biological markers are often used in environmental studies. Genetic markers In genetics, a molecular marker (identified as genetic marker) is a fragment of DNA that is associated with a certain location within the genome. Molecular markers are used in molecular biology and biotechnology to identify a particular sequence of DNA in a pool of unknown DNA. Types of genetic markers There are many types of genetic markers, each with particular limitations and strengths. Within genetic markers there are three different categories: "First Generation Markers", "Second Generation Markers", and "New Generation Marker ...

Cyclamen
''Cyclamen'' ( or ) is a genus of 23 species of perennial flowering plants in the family Primulaceae. ''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. It was traditionally classified in the family Primulaceae, was reclassified in the family Myrsinaceae in 2000 and finally, in 2009 with the introduction of the APG III system, was returned to the subfamily Myrsinoideae within the family Primulaceae. Names ''Cyclamen'' is Medieval Latin, from earlier Latin ''cyclamīnos'', from Ancient Greek κυκλάμινος, ''kyklā́mīnos'' (also ''kyklāmī́s''), from κύκλος, ''kýklos'' "circle", because of the round tuber. In English the species of the genus are commonly called by the genus name. In many languages cyclamen species are colloquially called by a name like the Englis ...
