Notoleptopus
''Notoleptopus'' is a monotypic genus of flowering plants in the family Phyllanthaceae. It is one of eight genera in the tribe Poranthereae. The sole species is ''Notoleptopus decaisnei''. It is a monoecious shrub, native to Australia, New Guinea, and Indonesia. ''Notoleptopus decaisnei'' had long been treated as a species of ''Leptopus'', but in 2007, a molecular phylogenetic study of DNA sequences found it to be sister to a clade consisting of ''Pseudophyllanthus'' and ''Poranthera''. In 2008, the new genus ''Notoleptopus'' was created for it. The species, ''N. decaisnei'', has eleven synonyms, and was first described as ''Andrachne decaisnei'' by George Bentham in 1873. The species epithet honours Joseph Decaisne. * ''Andrachne decaisnei'' Benth. * ''Andrachne decaisnei'' var.

Leptopus
''Leptopus'', the maidenbushes, are a genus of plants in the family Phyllanthaceae native to southern Asia from the Caucasus east to China and Maluku. The plants are monoecious herbs and shrubs with simple, entire leaves and small, green flowers. ''Leptopus'' is one of eight genera in the tribe PoranthereaePetra Hoffmann, Hashendra S. Kathriarachchi, and Kenneth J. Wurdack. 2006. "A Phylogenetic Classification of Phyllanthaceae." ''Kew Bulletin'' 61(1):37-53. and comprises 9 species. Maria S. Vorontsova and Petra Hoffmann. 2008.

Poranthereae
Poranthereae is a tribe in the plant family Phyllanthaceae. It is one of ten tribes in the family, and one of four tribes in the subfamily Phyllanthoideae. Poranthereae comprises about 111 species, distributed into eight genera. The largest genera and the number of species in each are ''Actephila'' (31), ''Meineckia'' (30), and ''Andrachne'' (22). The tribe consists of herbs, shrubs, and small to medium trees. They have a cosmopolitan distribution, occurring on all continents, except Antarctica. The circumscription and classification of Poranthereae were substantially revised following phylogenetic analysis of DNA sequences from members of the family Phyllanthaceae. Within Poranthereae, groups of related genera are strongly correlated with habitat and geographical distribution. For example, ''Notoleptopus'', ''Pseudophyllanthus'', and ''Poranthera'' are restricted to the Old World Southern Hemisphere.

Maria Vorontsova (botanist)
Maria Sergeevna Vorontsova (russian: Мария Сергеевна Воронцова; born 1979) is a Russian-born botanist, specializing in the taxonomy of Poaceae (grasses). She was responsible for authoring the taxon for Solanum agnewiorum and Solanum umtuma. She is a member of the Accelerated Taxonomy department at Royal Botanic Gardens, Kew. She is one of the co-authors and maintainers of GrassBase, and is an editor of the journal, ''Phytotaxa''. In 2010, she identified a new species of Africa spiny aubergine, '' Solanum ruvu'', which had been collected only once in the wild ten years earlier. A subsequent expedition failed to locate it, and it is now believed to be extinct due to deforestation Deforestation or forest clearance is the removal of a forest or stand of trees from land that is then converted to non-forest use. Deforestation can involve conversion of forest land to farms, ranches, or urban use. The most concentrated d .... Publications * * * ...

Research
Research is "creativity, creative and systematic work undertaken to increase the stock of knowledge". It involves the collection, organization and analysis of evidence to increase understanding of a topic, characterized by a particular attentiveness to controlling sources of bias and error. These activities are characterized by accounting and controlling for biases. A research project may be an expansion on past work in the field. To test the validity of instruments, procedures, or experiments, research may replicate elements of prior projects or the project as a whole. The primary purposes of basic research (as opposed to applied research) are documentation, Discovery (observation), discovery, interpretation (philosophy), interpretation, and the research and development (R&D) of methods and systems for the advancement of human knowledge. Approaches to research depend on epistemology, epistemologies, which vary considerably both within and between humanities and sciences. ...

DNA Sequence
DNA sequencing is the process of determining the nucleic acid sequence – the order of nucleotides in DNA. It includes any method or technology that is used to determine the order of the four bases: adenine, guanine, cytosine, and thymine. The advent of rapid DNA sequencing methods has greatly accelerated biological and medical research and discovery. Knowledge of DNA sequences has become indispensable for basic biological research, DNA Genographic Projects and in numerous applied fields such as medical diagnosis, biotechnology, forensic biology, virology and biological systematics. Comparing healthy and mutated DNA sequences can diagnose different diseases including various cancers, characterize antibody repertoire, and can be used to guide patient treatment. Having a quick way to sequence DNA allows for faster and more individualized medical care to be administered, and for more organisms to be identified and cataloged. The rapid speed of sequencing attained with modern D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sister Taxon
In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree. Definition The expression is most easily illustrated by a cladogram: Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC. The whole clade ABC is itself a subtree of a larger tree which offers yet more sister group relationships, both among the leaves and among larger, more deeply rooted clades. The tree structure shown connects through its root to the rest of the universal tree of life. In cladistic standards, taxa A, B, and C may represent specimens, species, genera, or any other taxonomic units. If A and B are at the same taxonomi ...

Clade
A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. Rather than the English term, the equivalent Latin term ''cladus'' (plural ''cladi'') is often used in taxonomical literature. The common ancestor may be an individual, a population, or a species (extinct or extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed monophyletic (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming taxa that are not clades; that is, taxa that are not monophyletic. Some of the relationships between organisms ...

Pseudophyllanthus
''Pseudophyllanthus'' is a monotypic genus of flowering plants in the family Phyllanthaceae. It is one of the eight genera in the tribe Poranthereae. Its closest relative is ''Poranthera''. Its sole species is ''Pseudophyllanthus ovalis''. It is a dioecious, or rarely monoecious, shrub or small tree, native to southern Africa. It had been included in the genus ''Andrachne'', but in 2007 a molecular phylogenetic study of DNA sequence DNA sequencing is the process of determining the nucleic acid sequence – the order of nucleotides in DNA. It includes any method or technology that is used to determine the order of the four bases: adenine, guanine, cytosine, and thymine. T ...s showed that it did not belong there.Maria S.

Joseph Decaisne
Joseph Decaisne (7 March 1807 – 8 January 1882) was a French botanist and agronomist. He became an ''aide-naturaliste'' to Adrien-Henri de Jussieu (1797-1853), who served as the chair of rural botany. It was during this time that he began to study plants brought back by various travelers like those of Victor Jacquemont (1801-1832) from Asia. Decaisne used applied research, most notably on the agronomy of the Rubia tinctorum, madder, the Yam (vegetable), yam and the ramie. He was also interested in algae. Biography Although born in Brussels, Belgium, he exercised his activity exclusively in Paris. He entered in 1824 as a gardener at the ''Muséum national d'histoire naturelle'' (French museum of natural history) and became, in 1832, head of the ''carré des semis'' section. He also worked at the ''Jardin des Plantes'' and collaborated with Asa Gray. In 1847 he chaired Statistical Agriculture department in the College de France. In 1850, Decaisne followed Charles-François Brisse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
