ADA Clade
The ADA clade is the earliest-branching monophyletic clade of the flowering plant subfamily Faboideae (or Papilionaceae). Evidence for this clade was sparse until recent molecular phylogenies that included basal faboid genera that previously had been poorly sampled. Description This clade is composed of a morphologically eclectic collection of genera. It is one of only three clades (the other two being Swartzieae and the ''Cladrastis'' clade) in Faboideae that lack the 50-Kb plastid DNA inversion that is characteristic of the Meso-Papilionoideae. The name of this clade is informal and is not assumed to have any particular taxonomic rank like the names authorized by the ICBN or the ICPN. The clade does not currently have a node-based definition and no morphological synapomorphies In phylogenetics, an apomorphy (or derived trait) is a novel character or character state that has evolved from its ancestral form (or plesiomorphy). A synapomorphy is an apomorphy shared by two or m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Castanospermum Australe
''Castanospermum australe'' (Moreton Bay chestnut or blackbean), the only species in the genus ''Castanospermum'', is a flowering plant in the family Fabaceae, native to the east coast of Australia in Queensland and New South Wales, and to the Pacific islands of Vanuatu, New Caledonia, and the island of New Britain (Papua New Guinea). Growth It is a large evergreen tree growing to tall, though commonly much smaller. The leaves are long and broad, pinnate, with 11-15 leaflets. The flowers are bicoloured red and yellow, long, produced in racemes long. The fruit is a cylindrical pod long and diameter, the interior divided by a spongy substance into one to five cells, each of which contains a large chestnut-like seed. Common names The 1889 book 'The Useful Native Plants of Australia' records the common names of ''Castanospermum australe'' as "Moreton Bay Chestnut" and "Bean tree" and notes that it was called "Irtalie" by Aboriginal people of the Richmond and Clarence Rivers ...

Swartzieae
The tribe Swartzieae is an early-branching monophyletic clade of the flowering plant subfamily Faboideae or Papilionaceae. Traditionally this tribe has been used as a wastebasket taxon to accommodate genera of Faboideae which exhibit actinomorphic, rather than zygomorphic floral symmetry and/or incompletely differentiated petals and free stamens. It was recently revised and most of its genera were redistributed to other tribes (Amburaneae, Baphieae, and Exostyleae). Under its new circumscription, this clade is consistently resolved in molecular phylogenies. Members of this tribe possess "non-papilionate swartzioid flowers €¦argely characterized by a tendency to lack petals combined with a profusion and elaboration of free stamens" and a "lack of unidirectional order in the initiation of the stamens". They also have "complete or near complete fusion of sepals resulting from intercalary growth early in development, relatively numerous stamens, and a single or no petal, with other pe ...

PhyloCode
The ''International Code of Phylogenetic Nomenclature'', known as the ''PhyloCode'' for short, is a formal set of rules governing phylogenetic nomenclature. Its current version is specifically designed to regulate the naming of clades, leaving the governance of species names up to the rank-based nomenclature codes ('' ICN'', ''ICNCP'', '' ICNP'', '' ICZN'', '' ICVCN''). The ''PhyloCode'' is associated with the International Society for Phylogenetic Nomenclature (ISPN). The companion volume, ''Phylonyms'', establishes 300 taxon names under ''PhyloCode'', serving as examples for those unfamiliar with the code. RegNum is an associated online database for registered clade names. The ''PhyloCode'' regulates phylogenetic nomenclature by providing rules for deciding which associations of names and definitions are considered established, which of those will be considered homonyms or synonyms, and which one of a set of synonyms or homonyms will be considered accepted (generally the one regi ...

ICBN
The ''International Code of Nomenclature for algae, fungi, and plants'' (ICN) is the set of rules and recommendations dealing with the formal botanical names that are given to plants, fungi and a few other groups of organisms, all those "traditionally treated as algae, fungi, or plants".. It was formerly called the ''International Code of Botanical Nomenclature'' (ICBN); the name was changed at the International Botanical Congress in Melbourne in July 2011 as part of the ''Melbourne Code''. which replaced the ''Vienna Code'' of 2005. The current version of the code is the ''Shenzhen Code'' adopted by the International Botanical Congress held in Shenzhen, China, in July 2017. As with previous codes, it took effect as soon as it was ratified by the congress (on 29 July 2017), but the documentation of the code in its final form was not published until 26 June 2018. The name of the ''Code'' is partly capitalized and partly not. The lower-case for "algae, fungi, and plants" indica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxonomic Rank
In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in an ancestral or hereditary hierarchy. A common system consists of species, genus, family (biology), family, order (biology), order, class (biology), class, phylum (biology), phylum, kingdom (biology), kingdom, domain (biology), domain. While older approaches to taxonomic classification were phenomenological, forming groups on the basis of similarities in appearance, organic structure and behaviour, methods based on genetic analysis have opened the road to cladistics. A given rank subsumes under it less general categories, that is, more specific descriptions of life forms. Above it, each rank is classified within more general categories of organisms and groups of organisms related to each other through inheritance of phenotypic trait, traits or features from common ancestors. The rank of any ''species'' and the description of its ''genus'' is ''basic''; which means that to iden ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meso-Papilionoideae
Meso-Papilionoideae is a monophyletic clade of the flowering plant subfamily Faboideae (or Papilionoideae) that includes the majority of papilionoid legumes. This clade is consistently resolved in molecular phylogenies. It contains many agronomically important genera, including ''Arachis'' (peanut), ''Cicer'' (chickpea), ''Glycine'' (soybean), ''Medicago'' (alfalfa), ''Phaseolus'' (common bean), ''Trifolium'' (clover), ''Vicia'' (vetch), and ''Vigna'' (mung bean). Description This clade circumscribes six subordinate clades: one traditional tribe (Exostyleae) and five informal clades (the genistoids, the vataireoids, the dalbergioids, the ''Andira'' clade, and the Old World Clade), as well as the genus ''Amphimas''. The clade has the following ICPN-compliant, node-based definition: The most inclusive crown clade exhibiting the structural rearrangement in the plastid genome (inversion of a ~50 Kb segment in the large-single copy region with endpoints between the ''accD'' and ''t ...

Plastid
The plastid (Greek: πλαστός; plastós: formed, molded – plural plastids) is a membrane-bound organelle found in the Cell (biology), cells of plants, algae, and some other eukaryotic organisms. They are considered to be intracellular endosymbiotic cyanobacteria. Examples include chloroplasts (used for photosynthesis), chromoplasts (used for pigment synthesis and storage), and leucoplasts (non-pigmented plastids that can sometimes differentiate). The event which led to permanent endosymbiosis in the Archaeplastida clade (of Embryophyte, land plants, red algae, and green algae) probably occurred with a cyanobiont (a symbiotic cyanobacteria) related to the genus ''Gloeomargarita lithophora, Gloeomargarita'', around 1.5 billion years ago. A later primary endosymbiosis event occurred in photosynthetic ''Paulinella'' amoeboids about 90–140 million years ago. This plastid belongs to the "PS-clade" (of the cyanobacteria genera ''Prochlorococcus'' and ''Synechococcus''). Chloroplas ...

Cladrastis Clade
The ''Cladrastis'' clade is a monophyletic clade of the flowering plant subfamily Faboideae (or Papilionaceae) that is found in eastern Asia and southern North America. It is consistently resolved in molecular phylogenies and is sister to the Meso-Papilionoideae. Evidence for the existence of this clade was first proposed based on morphological (floral), cytological, and biochemical evidence. It is predicted to have diverged from the other legume lineages 47.4±2.6 million years ago (in the Eocene). Description This clade is composed of three genera: ''Cladrastis'', the monotypic ''Pickeringia'', and ''Styphnolobium''. Fossils of species of ''Cladrastis'' and ''Styphnolobium'' have been discovered. The name of this clade is informal and is not assumed to have any particular taxonomic rank like the names authorized by the ICBN or the ICPN. The clade is defined as:"The most inclusive crown clade containing ''Cladrastis kentukea'' (Dum. Cours.) Rudd 1971 but not ''Dermatophyllum s ...

Molecular Phylogenetics
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.

Faboideae
The Faboideae are a subfamily of the flowering plant family Fabaceae or Leguminosae. An acceptable alternative name for the subfamily is Papilionoideae, or Papilionaceae when this group of plants is treated as a family. This subfamily is widely distributed, and members are adapted to a wide variety of environments. Faboideae may be trees, shrubs, or herbaceous plants. Members include the pea, the sweet pea, the laburnum, and other legumes. The pea-shaped flowers are characteristic of the Faboideae subfamily and root nodulation is very common. Genera The type genus, ''Faba'', is a synonym of ''Vicia'', and is listed here as ''Vicia''. *''Abrus'' *''Acmispon'' *''Acosmium'' *'' Adenocarpus'' *'' Adenodolichos'' *'' Adesmia'' *'' Aenictophyton'' *''Aeschynomene'' *'' Afgekia'' *''Aganope'' *'' Airyantha'' *''Aldina'' *''Alexa'' *''Alhagi'' *'' Alistilus'' *'' Almaleea'' *'' Alysicarpus'' *'' Amburana'' *''Amicia'' *'' Ammodendron'' *'' Ammopiptanthus'' *'' Ammothamnus'' *'' ...

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] |
