Recent cladistic analyses are revealing the phylogeny of flowering plants in increasing detail, and there is support for monophyly many major groups above family level.With elements branching sequence established, a revised suprafamilial classification becomes both feasible desirable.Here we present 462 plant families 40 putatively monophyletic orders small number monophyletic, informal higher groups.The latter monocots, commelinoids, eudicots, core rosids including eurosids I II, asterids...
Phylogenetic interrelationships in the enlarged order Ericales were investigated by jackknife analysis of a combination DNA sequences from plastid genes rbcL , ndhF atpB and mitochondrial atp1 matR . Several well‐supported groups identified, but neither all gene nor any one alone fully resolved relationships between major clades Ericales. All families except Theaceae found to be monophyletic. Four families, Marcgraviaceae, Balsaminaceae, Pellicieraceae, Tetrameristaceae form monophyletic...
Abstract Phylogenetic relationships of the two Malagasy Sapotaceae endemic genera Capurodendron and Tsebona have been unclear until now. Recent collections from Madagascar, as well a better representation tribe Isonandreae, altogether 95 terminals, were used to estimate phylogeny subfamily Sapotoideae. We analysed sequences nrDNA (ITS) cpDNA ( trnH‐psbA ) with Bayesian inference parsimony jackknifing. As in previous analyses, Sapoteae Sideroxyleae are recovered monophyletic. In addition,...
We present the first cladistic study of largely tropical family Sapotaceae based on both morphological and molecular data. The data were analyzed with standard parsimony jackknife algorithms using equally successive weighted characters. are confirmed to constitute two main evolutionary lineages corresponding tribes Isonandreae-Mimusopeae-Sideroxyleae Chrysophylleae-Omphalocarpeae. Sideroxyleae monophyletic, Isonandreae polyphyletic as presently circumscribed, suggested by analyses, subtribe...
The phylogenetic interrelationships in Primulaceae, Myrsinaceae, and Theophrastaceae were investigated using DNA sequence data from the chloroplast genes atpB, ndhF , rbcL. three analyzed separately, together, combination with morphology, parsimony jackknifing. are further explored by analyses of first second codon position only, third positions transversions only. results show that all contribute group support to tree, whereas provide most structure atpB rbcL trees. Analyzed have little...
The diverse and species‐rich order Ericales has found considerable interest among systematists in recent years. Molecular phylogenetic studies not only have convincingly demonstrated the monophyly of order, comprising 23 families formerly placed three different subclasses (Asteridae, Dilleniidae, Rosidae), but also resolved as sister to euasterids. Most ericalean are well circumscribed been or currently subject intrafamilial studies. In spite all attention that received recently, there...
The tribe Inuleae Cass. has been subject to a critical investigation. many technical characters that are traditionally used in classification of the scrutinized, discussed, and analysed by means computerized parsimony program (PAUP). With one representative from each tribes Vernonieae, Liabeae, Lactuceae as outgroups, three different analyses have performed. Strict consensus trees for separate presented discussed. A tree based on cladogram topologies obtained all is also presented. taxonomic...
The phylogeny of a representative group genera and species from the Sapotaceae tribe Chrysophylleae, mainly Australia New Caledonia, was studied by jackknife analyses sequences nuclear ribosomal DNA. conflicts with current opinions on generic delimitation in Sapotaceae. Pouteria Niemeyera, as presently circumscribed, are both shown to be nonmonophyletic. In contrast, all currently assigned these other segregate confined Australia, or neighboring islands, form supported clade. Earlier...
The Lecythidaceae comprise a pantropical family best known for the edible seeds of Brazil nut ( Bertholletia excelsa ) and cannon‐ball tree Couroupita guianensis ), which is planted as botanical curiosity in subtropical tropical gardens. In addition, species are often among most common neotropical forests, especially Amazon Basin. diverse abundant considered to be an indicator undisturbed or scarcely disturbed lowland forests; thus, what learned about its evolution, ecology, biogeography may...
Cladistic parsimony analyses, based on morphological data, have been undertaken with the purpose of identifying major monophyletic groups and phylogenetic interrelationships within Primulales. Actinidia (Actinidiaceae, Ericales) three genera from two families Ebenales (Diospyros Ebenaceae Manilkara Monotheca Sapotaceae) were used as outgroups in analyses. The results indicate that Primulaceae, Theophrastaceae, Myrsinaceae (excluding Maesa) represent groups. found to be paraphyletic, majority...
Species diversity is unequally distributed across the globe, with greatest concentration occurring in tropics. Even within tropics, there are significant differences numbers of taxa found each continental region. Manilkara a pantropical genus trees Sapotaceae comprising c. 78 species. Its distribution allows for biogeographic investigation and testing whether rates diversification differ amongst tropical regions. The age geographical origin inferred to determine Gondwanan break-up,...
Reconstructing the biogeographic history of groups present in continuous arid landscapes is challenging due to difficulties defining discrete areas for analyses, and even more so when species largely overlap both terms geography habitat preference. In this study, we use a novel approach estimate ancestral small plant genus Centipeda. We apply diffusion by relaxed random walk where each sampled from its extant distribution on an empirical time-calibrated species-trees. Using previously...
The phylogeny of the Sapotaceae was investigated by DNA sequence analysis chloroplast gene ndhF. Three or possibly four main evolutionary lineages were identified. Sarcosperma is sister group all other Sapotaceae, which together form two strongly supported monophyletic groups. One large clade with strong support comprised tribes Isonandreae, Mimusopeae, and Sideroxyleae, also includes genus Capurodendron tribe Chrysophylleae. second formed Chrysophylleae Omphalocarpeae, as well Diploon...

To determine whether the fragmented pantropical distribution of present day Sideroxyleae primarily is result long-distance dispersals or represents remnants a once continuous in northern hemisphere, boreotropical flora, we used phylogenetic analyses chloroplast and nuclear ribosomal DNA data, Bayesian molecular dating, estimation ancestral areas. Incongruence between two data sets was examined with low copy gene phylogeny to discover any occurrences reticulate evolution. The Pacific clade...
Internal transcribed spacer (ITS) ribosomal DNA sequence data were generated for 80 of the c. 200 species Isonandreae and added to from African Neotropical representatives in subfamily Sapotoideae outgroups Sapotaceae. Bayesian dating ancestral area reconstruction indicated that are derived within an grade. Multiple Australasian or lineages Sundanian South-East Asia with stem ages originating late Oligocene.

Summary What causes the disparity in biodiversity among regions is a fundamental question biogeography, ecology, and evolutionary biology. Evolutionary biogeographic processes (speciation, extinction, dispersal) directly determine species richness patterns, can be studied using integrative phylogenetic approaches. However, strikingly high of East Asia relative to other Northern Hemisphere remains poorly understood from this perspective. Here, for first time, we test two general hypotheses...
Abstract The Inula complex (Asteraceae: Inulinae) is a monophyletic group which comprises eight genera distributed in Eurasia and Africa: Amblyocarpum, Carpesium, Chrysophthalmum, Inula, Pentanema, Rhanteriopsis, Telekia , Varthemia. With the aim to shed light on circumscription of these genera, phylogenetic analyses were performed with 293 new DNA sequences (ITS region from nrDNA three plastid spacers cpDNA: rps16–trnQ, rpl32–trnL, ndhF–rpl32). It concluded that both Pentanema are...
