The tribe Sophoreae is one of the subdivisions of the plant family Fabaceae. 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. [2] [3] [4] Various morphological [5] [6] [7] [8] and molecular [9] [10] [11] [12] [13] analyses indicated that Sophoreae as traditionally circumscribed was polyphyletic. [14] This led to a re-circumscription of Sophoreae, which resulted in the transfer of many genera to other tribes (Amburaneae, Angylocalyceae, Baphieae, Camoensieae, the Cladrastis clade, Exostyleae, Leptolobieae, Ormosieae, Podalyrieae, and the Vataireoids). [2] This also necessitated the inclusion of two former tribes, Euchresteae and Thermopsideae, in the new definition of Sophoreae. [2] [15] [16] [17] [18] Tribe Sophoreae, as currently circumscribed, consistently forms a monophyletic clade in molecular phylogenetic analyses. [2] [12] [17] [19] [20] [21] [22] The Sophoreae arose 40.8 ± 2.4 million years ago (in the Eocene). [8] [23]

Contents

Description of morphological synapomorphies has yet to be undertaken, but members of this tribe can be distinguished by the relatively simple flowers, unspecialized pinnate leaves, accumulation of quinolizidine alkaloids, [24] and the presence of free stamens. [2] The tribe does have a node-based definition: the crown clade originating from the most recent common ancestor of Bolusanthus speciosus (Bolus) Harms and Sophora davidii (Franch.) Pavol.. [23]

Genera

Sophoreae comprises the following genera: [2]

Notes

  1. Often included in Sophora , rather than treated as a segregate genus.

<i>Camoensia</i> (plant) Genus of legumes

Camoensia is a genus of 2 species of lianas in the family Fabaceae, subfamily Faboideae, native to the Gulf of Guinea, Africa. C. scandens is cultivated as an ornamental plant; it has one of the largest leguminous flowers, up to 20 cm across. The genus has classically been assigned to the tribe Sophoreae, but was recently assigned to its own monophyletic tribe, Camoensieae, on the basis of molecular phylogenetic evidence. Species of Camoensia are known to produce quinolizidine alkaloids, consistent with their placement in the genistoid clade.

The tribe Dalbergieae is an early-branching clade within the flowering plant subfamily Faboideae. Within that subfamily, it belongs to an unranked clade called the dalbergioids. It was recently revised to include many genera formerly placed in tribes Adesmieae and Aeschynomeneae and to be included in a monophyletic group informally known as the dalbergioids sensu lato. The members of this tribe have a distinctive root nodule morphology, often referred to as an "aeschynomenoid" or "dalbergioid" nodule.

<span class="mw-page-title-main">Swartzieae</span> Clade of legumes

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. Under its new circumscription, this clade is consistently resolved in 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 development, relatively numerous stamens, and a single or no petal, with other petals not at all apparent in development." The tribe is predicted to have diverged from the other legume lineages 48.9±2.8 million years ago.

The vataireoids are an early-branching monophyletic clade of the flowering plant subfamily Faboideae that are mostly found in northern South America, primarily Brazil.

<span class="mw-page-title-main">Inverted repeat-lacking clade</span> Group of flowering plants

The inverted repeat-lacking clade(IRLC) is a monophyletic clade of the flowering plant subfamily Faboideae (or Papilionaceae). Faboideae includes the majority of agriculturally-cultivated legumes. 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 characterized by the loss of one of the two 25-kb inverted repeats in the plastid genome that are found in most land plants. It is consistently resolved in molecular phylogenies. The clade is predicted to have diverged from the other legume lineages 39.0±2.4 million years ago (in the Eocene). It includes several large, temperate genera such as AstragalusL., HedysarumL., MedicagoL., OxytropisDC., SwainsonaSalisb., and TrifoliumL..

<span class="mw-page-title-main">Exostyleae</span> Clade of legumes

The tribe Exostyleae is an early-branching monophyletic clade of the flowering plant subfamily Faboideae that are mostly found in Neotropical rainforests.

<i>Cladrastis</i> clade Clade of legumes

The Cladrastis clade is a monophyletic clade of the flowering plant subfamily Faboideae 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.

The Andira clade is a predominantly Neotropical, monophyletic clade of the flowering plant subfamily Faboideae. The members of this clade were formerly included in tribe Dalbergieae, but this placement was questioned due to differences in wood anatomy and fruit, seed, seedling, floral, and vegetative characters. Recent molecular phylogenetic evidence has shown that they belong to a unique evolutionary lineage. It is predicted to have diverged from the other legume lineages in the late Eocene).

The tribe Ormosieae is one of the subdivisions of the plant family Fabaceae, primarily found in tropical regions of the Americas, but also in southeast Asia and northern Australia. The members of this tribe were formerly included in tribe Sophoreae, but were recently circumscribed into a new tribe. The members of this tribe consistently form a monophyletic clade in molecular phylogenetic analyses. The tribe does not currently have a node-based definition, but morphological synapomorphies have been tentatively identified: "mostly dehiscent pods with woody valves" and "tufts of minute colleter-like glands in the axils of bract and bracteoles". Like other genistoids, members of tribe Ormosieae are known to produce quinolizidine alkaloids.

<span class="mw-page-title-main">Genistoids</span> Clade of legumes

The Genistoids are one of the major radiations in the plant family Fabaceae. Members of this phylogenetic clade are primarily found in the Southern hemisphere. Some genera are pollinated by birds. The genistoid clade is consistently resolved as monophyletic in molecular phylogenetic analyses. It is estimated to have arisen 56.4 ± 0.2 million years ago. A node-based definition for the genistoids is: "the MRCA of Poecilanthe parviflora and Lupinus argenteus." One morphological synapomorphy has been tentatively identified: production of quinolizidine alkaloids. Some genera also accumulate pyrrolizidine. A new genus, to be segregated from Clathrotropis, has also been proposed to occupy an undetermined position within the genistoid clade.

<span class="mw-page-title-main">Dalbergioids</span> Clade of legumes

The dalbergioids are an early-branching monophyletic clade of the flowering plant subfamily Faboideae or Papilionaceae. They are pantropical, particularly being found in the neotropics and sub-Saharan Africa. This clade is consistently resolved as monophyletic in molecular phylogenetic analyses. It is estimated to have arisen 55.3 ± 0.5 million years ago. A node-based definition for the dalbergioids is: "The least inclusive crown clade that contains Amorpha fruticosaL. 1753 and Dalbergia sissooRoxb. ex DC. 1825." Indehiscent pods may be a morphological synapomorphy for the clade.

<span class="mw-page-title-main">Baphieae</span> Tribe of legumes

The tribe Baphieae is one of the subdivisions of the plant family Fabaceae. The Baphieae tribe arose 55.3 ± 0.4 million years ago.

Meso-Papilionoideae is a monophyletic clade of the flowering plant subfamily Faboideae 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, Trifolium (clover), Vicia (vetch), and Vigna.

<span class="mw-page-title-main">Mirbelioids</span> Group of legumes

The Mirbelioids are an informal subdivision of the plant family Fabaceae that includes the former tribes Bossiaeeae and Mirbelieae. They are consistently recovered as a monophyletic clade in molecular phylogenies. The Mirbelioids arose 48.4 ± 1.3 million years ago. Members of this clade are mostly ericoid (sclerophyllous) shrubs with yellow and red flowers found in Australia, Tasmania, and Papua-New Guinea. 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. Members of this clade exhibit unusual embryology compared to other legumes, either enlarged antipodal cells in the embryo sac or the production of multiple embryo sacs. There has been a shift from bee pollination to bird pollination several times in this clade. Mirbelioids produce quinolizidine alkaloids, but unlike most papilionoids, they do not produce isoflavones. Many of the Mirbelioids have pseudoraceme inflorescences.
