The oldest fossil evidence of Annonaceae is described as the genus Futabanthus, from the Late Cretaceous (Coniacian) of Japan, which represents a minimum age of c. 89 million years ago for the most recent common ancestor (crown group) of the family. (wikipedia.org)
We recover all the genera as monophyletic, except the genus Uvariopsis for which the species Uvariopsistripetala falls outside this clade. (bvsalud.org)
Below the genus level, the genera Isolona, Monodora, Uvariastrum, Uvariodendron and Uvariopsis show weakly supported nodes and phylogenetic conflicts, suggesting that population level processes of evolution might occur in these clades. (bvsalud.org)
The C4 Cyperus clade of the genus Cyperus has been particularly difficult to resolve. (frontiersin.org)
Targeted sequencing provides new insights into the evolution of morphology in the C4 Cyperus clade, demonstrating for example that the former segregate genus Alinula is polyphyletic despite its seeming morphological integrity. (frontiersin.org)
The subfamilial and tribal classification is followed in World Annonaceae which presents an overview of all Annonaceae genera and taxonomic, distribution and photographic information for a large number of species. (wikipedia.org)
Phylogenetic tree3
A dated and well-resolved phylogenetic tree of Annonaceae was used to study diversification patterns in the family in order to identify factors that drive speciation and the evolution of morphological (key) characters. (myspecies.info)
Most of the speciation in Annonaceae is not distinguishable from a random branching process (i.e. chance), and no special explanations are therefore necessary for the distribution of species richness across the major part of the phylogenetic tree for Annonaceae. (myspecies.info)
Here, we used a robust phylogenomic approach, including all the 90 currently accepted species, with several specimens per species, and based on more than 300 Annonaceae-specific nuclear genes, to infer the phylogenetic tree of the Monodoreae and test the limits between the genera and species. (bvsalud.org)
Taxa2
Keys for the identification of Annonaceae genera (separately for Neotropical, African/Madagascan, and Asian/Australian taxa) are presented in: For a concise bibliographic overview of the taxonomic literature (1900 to 2012) see: Both plastid DNA markers and morphological characters provide evidence that Anaxagorea is the sister clade to the rest of the family. (wikipedia.org)
Previous studies based on a limited set of markers resolved relationships among Cyperus species using the C3 photosynthetic pathway, but not among C4 Cyperus clade taxa. (frontiersin.org)
Genera1
Monodoreae (Annonaceae) is a tribe composed of 11 genera and 90 species restricted to the tropical African rain forests. (bvsalud.org)
Eupomatiaceae1
The APG II system places Annonaceae as most closely related to the small Magnoliid family Eupomatiaceae. (wikipedia.org)
Angiosperms1
We test the ability of two targeted sequencing kits to resolve relationships in the C4 Cyperus clade, the universal Angiosperms-353 kit and a Cyperaceae-specific kit. (frontiersin.org)
Diversification2
Furthermore, the difference in species numbers between subfamilies Annonoideae (former long branch clade) and Malmeoideae (former short branch clade) cannot be attributed to significant differences in the diversification rate. (myspecies.info)
Only for a small number of clades can key innovations be invoked to explain the elevated rate of diversification. (myspecies.info)
Species1
Phylogenetic analysis placed the new species in the Pristimantis conspicillatus species group and the sister lineage of the Atlantic Forest clade comprising P. ramagii, P. paulodutrai and the P. vinhai species complex. (blogspot.com)
Lineage1
Many of the bolded characters in the characterization above are apomorphies of more or less inclusive clades of streptophytes along the lineage leading to the embryophytes, not apomorphies of crown-group embryophytes per se . (mobot.org)
Family4
The Annonaceae are a family of flowering plants consisting of trees, shrubs, or rarely lianas commonly known as the custard apple family or soursop family. (wikipedia.org)
The ages of Annonaceae clades inferred using fossil evidence and molecular clock-based dating techniques suggests that the pantropical distribution of the family originated subsequent to the break-up of the Gondwanan supercontinent, as the result of a combination of geodispersal tracking the expansion of the boreotropical flora during the Eocene and more recent long-distance dispersal events. (wikipedia.org)
[6] Molecular phylogenetic studies of DNA sequences have shown it to be the second diverging clade in Alismatales, after the most basal clade, the family Araceae . (wikimili.com)
The most authoritative modern treatment, however, the APG III system of 2009, places the family in the order Liliales, in the clade monocots. (wikimili.com)
Molecular2
Monophyly and inter-familial systematics have been well supported for Annonaceae by a combination of morphological and molecular evidence. (wikipedia.org)
Molecular phylogenetic studies also have shown that Sri Lankan caecilian fauna is of monophyletic origin, those of the south western lowlands comprising a clade, possibly representing a relatively recent divergence from those of the central highlands. (chm-cbd.net)
Sister1
An unexpected result is that the Cyperus margaritaceus - Cyperus niveus complex comprises a clade separate from and sister to the core C4 Cyperus clade. (frontiersin.org)
Group1
Characters mentioned are those of the immediate common ancestor of the group, [] contains explanatory material, () features common in clade, exact status unclear. (mobot.org)
Eudicots1
To remedy this situation, we have used a morphological data set for living basal angiosperms (including basal eudicots and monocots) to assess the most parsimonious positions of early angiosperm fossils on cladograms of Recent plants, using constraint trees that represent the current range of hypotheses on higher-level relationships, and concentrating on Magnoliidae (the clade including Magnoliales, Laurales, Canellales, and Piperales) and eudicots. (jse.ac.cn)
Magnoliales1
to Magnoliaceae, Endressinia (late Aptian) to Magnoliales (the clade comprising Degeneria , Galbulimima , Eupomatia , and Annonaceae), and Walkeripollis pollen tetrads (late Barremian? (jse.ac.cn)
Subfamily1
This Special Issue - Advances in Legume Systematics 14 Part 1 - presents 16 papers focused on generic delimitation across subfamily Caesalpinioideae (Leguminosae) which includes the mimosoid clade (former subfamily Mimosoideae). (pensoft.net)
Annonoideae2
Gêneros androdioicos surgiram várias vezes em diferentes linhagens de Annonaceae, tanto na subfamília Annonoideae, quanto na subfamília Malmeoideae. (usp.br)
Furthermore, the difference in species numbers between subfamilies Annonoideae (former long branch clade) and Malmeoideae (former short branch clade) cannot be attributed to significant differences in the diversification rate. (myspecies.info)
