Tribe Cardueae (thistles) forms one of the largest tribes in family Compositae (2400 species), with representatives almost every continent. The greatest species richness occurs Mediterranean region where it an important element its flora. New fossil evidence and a nearly resolved phylogeny are used here to reconstruct spatiotemporal evolution this group. •We performed maximum parsimony Bayesian phylogenetic inference based on nuclear ribosomal DNA chloroplast markers. Divergence times...
The genus Centaurea has traditionally been considered to be a complicated taxon. No attempt at phylogenetic reconstruction made since recent revisions in circumscription, and previous reconstructions did not include good representation of species. A new molecular survey is thus needed.Phylogenetic analyses were conducted using sequences the internal transcribed spacers (ITS) 1 2 5.8S gene. Parsimony Bayesian approaches used.A close correlation between geography tree based on ITS was found...
The Cardueae pose vexing systematic problems at several taxonomic levels. Tribal delimitation is controversial, with views ranging from a broadly defined comprising subtribes Echinopsidinae, Carlininae, Carduinae, and Centaureinae to more restrictive (comprising only Carduinae Centaureinae) tribal rank also given Echinopsideae (or Echinopeae) Carlineae. Furthermore, the circumscription of groups within broad divergent emphasizing differences in floral or achene morphology; distinction...
The new outline of relationships in basal branches the family Compositae Giseke confirms that sister group to tribe Cardueae Cass. are not Mutisieae Cass., but rather a African genera now classified as Tarchonantheae Kostel. This change implies monophyly must be reassessed on molecular basis. Moreover, collections recent years allow us extend our sampling 70 74 tribe. We performed study using one nuclear region (ITS) and two chloroplastic markers (trnL-trnF matK) addition more appropriate...
Increasing evidence suggests that geological or climatic events in the past triggered radiative diversification of both animals and plants on islands as well continents. The Qinghai–Tibetan Plateau (QTP) has been extensively uplifted since Miocene, but there is little information possible links between these biological this adjacent regions. Partly to explore such links, we have examined Saussurea (Asteraceae: Cardueae), a species-rich genus mostly endemic QTP, also occurs arid highlands...
Abstract We conducted a molecular phylogenetic study of the tribe Stipeae using nine plastid DNA sequences ( trnK‐matK, matK, trnH‐psbA, trnL‐F, rps3, ndhF, rpl32‐trnL, rps16‐trnK, rps16 intron), nuclear ITS regions, and micromorphological characters from lemma surface. Our large original dataset includes 156 accessions representing 139 species all genera currently placed in tribe. The maximum likelihood Bayesian analyses provide strong support for monophyly Stipeae; including, order,...
Abstract Comprising more than 25 000 species, the Sunflower Family (Compositae or Asteraceae) is largest family of flowering plants. Many its lineages have experienced recent and rapid radiations, has a deep widespread history large‐scale gene duplications polyploidy. most important evolutionary questions about family's diversity remain unanswered due to poor resolution lack support for major nodes phylogeny. Our group employed phylogenomics approach using Hyb‐Seq that includes sequencing...
Abstract The classification of the family Compositae (Asteraceae) has been much improved in last decades by application molecular methods culminating recompilation published 2009, Systematics, evolution, and biogeography . Additional evidence relationships come from use high‐throughput sequencing methods. Our late colleague Vicki Ann Funk (1947–2019) was a pioneer this line research. Together with her team, she contributed to achievement mature family, which left outlined. In paper, we...
Centaurea peltieri (C. sect. Melanoloma) is described and illustrated as a new endemic species from the Oriental High Atlas of Morocco. The morphology involucral bracts discriminant feature separating it other closely related section.
Summary Torrell, M., Garcia‐Jacas, N., Susanna, A. & Vallès, J.: Phylogeny in Artemisia (Asteraceae, Anthemideae) inferred from nuclear ribosomal DNA (ITS) sequences. – Taxon 48: 721‐736. 1999. ISSN 0040‐0262. The internal transcribed spacers (ITS‐1 and ITS‐2) of were sequenced for 33 populations 31 species Artemisia. sequence data support the monophyly genus its classical, broad sense, including Seriphidium Oligosporus. Five main clades are defined, corresponding largely to four groups...
Abstract: Sequences of the internal transcribed spacers (ITS1 and ITS2) nuclear ribosomal DNA were analysed for 44 Artemisia species (46 populations) representing all five classical subgenera geographical range genus, 11 from 10 genera closely related to Artemisia, six outgroup other Anthemideae. The results definitely support monophyly genus in its broadest sense (including some taxa segregated as independent genera, like Oligosporus Seriphidium ). Eight main clades are established this...
Abstract The circumscription and infrageneric classification of Campanula is highly controversial. Independent combined data from nuclear chloroplast sequences (trnL-trnF, ITS) were analyzed with Bayesian parsimony methods to elucidate the phylogenetic relationships allied genera, explore biological processes that occurred during evolution this genus. main sections subgenera related genera sampled extensively. Chromosome numbers, corolla types, habit capsule dehiscence mapped on trees search...
Background and Aims Section Acrocentron of the genus Centaurea is one largest sections with approx.100 species.The geographic distribution, centred in Mediterranean, makes it an excellent example for studies biogeographic history this biodiversity-rich region.† Methods Plastid (trnH-psbA) nuclear (ITS ETS) DNA sequence analysis was used phylogenetic reconstruction.Ancestral patterns were inferred by dispersal-vicariance (DIVA). † Key ResultsThe resulting phylogeny has implications sectional...
Abstract The Helichrysum‐Anaphalis‐Pseudognaphalium (HAP) clade is a major component of the tribe Gnaphalieae (Compositae) and includes genera Helichrysum, Anaphalis, Achyrocline Pseudognaphalium . Allopolyploid origins for at least two clades within HAP have previously been suggested, one involving genus Anaphalis Mediterranean‐Asian Helichrysum species, second part In present paper, with use nuclear ribosomal plastid DNA markers an extensive sampling clade, further evidence relevant to...
Abstract Climate changes are top biodiversity shapers, both during the past and future. Mapping most climatic stable unstable zones on Earth could improve our understanding of distribution evolution. Here, we present a set maps based global scale, high resolution (ca. 5 km) new Stability Index (CSI). The CSI considers bioclimatic variables for two different time ranges: (1) from Pliocene (3.3 Ma) to (CSI-past map set), using 12 periods PaleoClim representing warm cold cycles; (2) year 2100...
