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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Castanospermum Australe
''Castanospermum'' is a monotypic genus (i.e. a genus that contains only one species) in the legume family Fabaceae. The sole species is ''Castanospermum australe'', commonly known as Moreton Bay chestnut or black bean. It is native to rainforests on the east coast of Australia (Queensland and northeastern New South Wales), and to nearby islands of the southwest Pacific Ocean. It was first described in 1829, and has been cultivated around the world. Description The black bean is a large evergreen tree growing up 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. Taxonomy This species was first described in 1829 by English botanist Allan Cunningham, in a publication by Scottish n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swartzieae
The tribe (biology), tribe Swartzieae is an early-branching monophyly, 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 circumscription (taxonomy), 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 phylogeny, molecular phylogenies. Members of this tribe possess "non-papilionate swartzioid flowers[…]largely 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 de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

ICBN
The ''International Code of Nomenclature for algae, fungi, and plants'' (ICN or ICNafp) 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. For fungi the ''Code'' was revised by the ''San Juan Chapter F'' in 2018. The 2025 edition of ICBN, the ''Ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxonomic Rank
In biology, taxonomic rank (which some authors prefer to call nomenclatural rank because ranking is part of nomenclature rather than taxonomy proper, according to some definitions of these terms) is the relative or absolute level of a group of organisms (a ''taxon'') in a hierarchy that reflects evolutionary relationships. Thus, the most inclusive clades (such as Eukarya and Animalia) have the highest ranks, whereas the least inclusive ones (such as ''Homo sapiens'' or ''Bufo bufo'') have the lowest ranks. Ranks can be either relative and be denoted by an indented taxonomy in which the level of indentation reflects the rank, or absolute, in which various terms, such as species, genus, Family (biology), family, Order (biology), order, Class (biology), class, Phylum (biology), phylum, Kingdom (biology), kingdom, and Domain (biology), domain designate rank. This page emphasizes absolute ranks and the rank-based codes (the International Code of Zoological Nomenclature, Zoological Code, ...

Meso-Papilionoideae
Meso-Papilionoideae or 50-kb Inversion clade is a monophyletic clade of the flowering plant subfamily Faboideae (or Papilionoideae) that includes the majority of papilionoid legumes. 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). This clade is circumscribed by the presence of a 50 kb inverted DNA sequence in the plastome of member species and is consistently resolved in molecular phylogenies. The name Meso-Papilionoideae was proposed for this clade by Wojciechowski (2013). Its original name, 50-kb Inversion clade is still in use and the clade is still frequently referred to by this name in publications, as well as the Angiosperm Phylogeny Website and NCBI taxonomy browser. Description This clade circumscribes six subordinate clades: one traditional tribe (Exostyleae) and five i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plastid
A plastid is a membrane-bound organelle found in the Cell (biology), cells of plants, algae, and some other eukaryotic organisms. Plastids are considered to be intracellular endosymbiotic cyanobacteria. Examples of plastids include chloroplasts (used for photosynthesis); chromoplasts (used for synthesis and storage of pigments); leucoplasts (non-pigmented plastids, some of which can cellular differentiation, differentiate); and apicoplasts (non-photosynthetic plastids of apicomplexa derived from secondary endosymbiosis). A permanent primary endosymbiosis event occurred about 1.5 billion years ago in the Archaeplastida cladeEmbryophyte, land plants, red algae, green algae and glaucophytesprobably with a cyanobiont, a symbiotic cyanobacteria related to the genus ''Gloeomargarita lithophora, Gloeomargarita''. Another primary endosymbiosis event occurred later, between 140 and 90 million years ago, in the photosynthetic plastids ''Paulinella'' amoeboids of the cyanobacteria genera '' ...

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 The ''International Code of Nomenclature for algae, fungi, and plants'' (ICN or ICNafp) is the set of rules and recommendations dealing with the fo ...

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 phylogenetics, 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 (biology), 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 tre ...

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'' *'' Ammot ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (). The term angiosperm is derived from the Ancient Greek, Greek words (; 'container, vessel') and (; 'seed'), meaning that the seeds are enclosed within a fruit. The group was formerly called Magnoliophyta. Angiosperms are by far the most diverse group of Embryophyte, land plants with 64 Order (biology), orders, 416 Family (biology), families, approximately 13,000 known Genus, genera and 300,000 known species. They include all forbs (flowering plants without a woody Plant stem, stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. Angiosperms are distinguished from the other major seed plant clade, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the commo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
