The pantropical flowering plant family Annonaceae is the most species-rich of Magnoliales. Despite long-standing interest in systematics Annonaceae, no authoritative classification has yet been published light recent molecular phylogenetic analyses. Here, using largest, representative, dataset compiled on to date, we present, for first time, a robust family-wide tree and subsequent classification. We used supermatrix up eight plastid markers sequenced from 193 ingroup seven outgroup species....

Aim Rain forest-restricted plant families show disjunct distributions between the three major tropical regions: South America, Africa and Asia. Explaining these disjunctions has become an important challenge in biogeography. The pantropical family Annonaceae is used to test hypotheses that might explain diversification distribution patterns biota: museum hypothesis (low extinction leading steady accumulation of species); dispersal Asia via Indian rafting versus boreotropical geodispersal....

Abstract Aim African–Asian disjunctions are common in palaeotropical taxa, and typically explained by reference to three competing hypotheses: (1) ‘rafting’ on the Indian tectonic plate, enabling Africa‐to‐Asia dispersal; (2) migration via Eocene boreotropical forests; (3) transoceanic long‐distance dispersal. These hypotheses tested using Uvaria (Annonaceae), which is distributed tropical regions of Africa, Asia Australasia. Recent phylogenetic reconstructions genus show a clear correlation...

Abstract The Annonaceae, the largest family in early-divergent order Magnoliales, comprises 107 genera and c. 2,400 species. Previous molecular phylogenetic studies targeting different taxa have generated large quantities of partially overlapping DNA sequence data for many species, although a large-scale phylogeny based on maximum number representatives has never been reconstructed. We use supermatrix eight chloroplast markers ( rbcL , matK ndhF psbA-trnH trnL-F atpB-rbcL trnS-G ycf1 ) to...

Phylogenetic analyses of the Annonaceae consistently identify four clades: a basal clade consisting Anaxagorea, and small 'ambavioid' that is sister to two main clades, 'long branch clade' (LBC) 'short (SBC). Divergence times in family have previously been estimated using non-parametric rate smoothing (NPRS) penalized likelihood (PL). Here we use an uncorrelated lognormal (UCLD) relaxed molecular clock BEAST estimate diversification clades within with focus on Asian genus Pseuduvaria SBC....

• Acyl-CoA-binding proteins (ACBPs) show conservation in an acyl-CoA-binding domain (ACB domain) which binds acyl-CoA esters. Previous studies on plant ACBPs focused eudicots, Arabidopsis and Brassica. Here, we report the phylogeny characterization of ACBP family from monocot Oryza sativa (rice). Phylogenetic analyses were conducted using 16 genomes. Expression profiles rice under normal growth, as well biotic abiotic stress conditions, examined by quantitative real-time...

The pollination biology of Annonaceae has received considerable attention, with data now available for > 45% the genera (or genus-equivalent clades) included in recent molecular phylogenetic analyses. This provides a basis understanding evolutionary shifts system within family. present study focuses on subfamilies Anaxagoreoideae, Ambavioideae and Annonoideae, which robust, well-resolved trees are available. Information is summarized individual clades adaptations favouring different...

The majority of tribe Phyllantheae (Phyllanthaceae) is currently placed in the paraphyletic genus Phyllanthus and discussions have persisted on how to resolve this issue. Here, we split into ten monophyletic genera, which are all reinstatements former but with changes made circumscription constituent species each group. genera Breynia, Glochidion Synostemon were recently found be nested within ensued whether or not subsume everything s.l. Instead combining these here implement solution...

Abstract The highly polyphyletic status of the species­rich genus Polyalthia (Annonaceae) remains one most significant impediments to revisionary and floristic taxonomic research in family. Although has recently been reduced scope, remaining species still form a phylogenetically disparate morphologically heterogeneous assemblage. We use maximum parsimony, likelihood Bayesian phylogenetic reconstructions based on chloroplast DNA sequence data (matK, rbcL, trnL­F) show that segregate into...

Abstract Meiogyne (Annonaceae) comprises 15 species of trees and shrubs distributed in India, Indomalaya Australasia–Pacific. Previous molecular phylogenetic analyses, based on limited taxon sampling, have indicated that the small genus Fitzalania (2 spp.) is nested within . The centre diversity Meiogyne–Fitzalania group lies Australia (6 New Caledonia (4 spp.); this unique Annonaceae, some whose Australian Caledonian lineages been hypothesised to originated situ from Gondwanan ancestors....

A major goal of phylogenetic systematics is to understand both the patterns diversification and processes by which these are formed. Few studies have focused on ancient, species-rich Magnoliales clade its pattern. Within Magnoliales, pantropically distributed Annonaceae far most genus-rich family-level clade, with c. 110 genera 2,400 species. We investigated across identified traits that show varied associations rates using a time-calibrated phylogeny 835 species (34.6% sampling) 11,211...

Abstract The species-rich genus Polyalthia has previously been shown to be highly polyphyletic, with species represented in at least five different clades. that are associated Marsypopetalum and Trivalvaria (as revealed either by previous phylogenetic studies or inferred on the basis of comparative morphology) were included a molecular study based three chloroplast DNA regions (matK, rbcL trnL-F). Maximum parsimony, maximum likelihood Bayesian analyses consistently several form...

Abstract Uvaria (Annonaceae), a large palaeotropical genus of woody climbers, closely resembles several other smaller genera, including Anomianthus, Cyathostemma, Ellipeia, Ellipeiopsis and Rauwenhoffia. A molecular phylogenetic analysis this group was undertaken using maximum parsimony, likelihood Bayesian methods based on four chloroplast DNA regions (matK, psbA‐trnH spacer, rbcL trnL‐F). The resultant trees were moderately well resolved with significant statistical support for most nodes....

Recently published molecular phylogenies of the Annonaceae have confirmed long-held hypothesis that large paleotropical genus Polyalthia is polyphyletic. Species previously assigned to are now known belong up six distinct, generally well-supported clades. Three members a group species referred as hypoleuca complex form monophyletic (with 99% bootstrap support) only distantly related other sampled. Putative morphological synapomorphies assessed, and justification provided for validating new...
