Sequences of nuclear ribosomal DNA ITS region were used to estimate phylogenetic relationships of Alnus. We recognize three major clades in Alnus, including subgenera Alnobetula, Clethropsis, and Alnus; subgenus Alnobetula is sister to subgenera Clethropsis and Alnus. The eastern Asian subgenus or section Cremastogyne is embedded in the subgenus Alnus clade. Alnus nepalensis is part of subgenus Alnus, not subgenus Clethropsis. Alnus maritima is part of subgenus Clethropsis (excl. A. nepalensis… 

Genome skimming and plastid microsatellite profiling of alder trees (Alnus spp., Betulaceae): phylogenetic and phylogeographical prospects

Strong phylogeographic signals and recurrent cytoplasmic captures between co-occurring species are revealed, demonstrating that the plastid microsatellite profiling method is suitable for tracing the post-glacial spread of maternal lineages among alder species.

Phylogenetics of Betula (Betulaceae) inferred from sequences of nuclear ribosomal DNA

Sequences of the internal transcribed spacer region of nuclear ribosomal DNA were used to estimate relationships within Betula and support the closer affinity of B. uber, which is an endangered species in eastern North America, to B. lenta than toB.

Phylogenetic and Biogeographic Diversification of Berberidaceae in the Northern Hemisphere

Abstract Sequences of the chloroplast genes matK and rbcL and nuclear ribosomal ITS2 were used for phylogenetic analyses of Berberidaceae. Three major clades were recognized, corresponding to the

Phylogeography and genetic structure of a subarctic-alpine shrub species, Alnus alnobetula (Ehrh.) K. Koch s. l., inferred from chloroplast DNA markers

The green alder populations from central Sakhalin have a haplotype-rich composition including different genetic lineages that confirm the existence of a hotspot of genetic diversity in this part of the island.

Polymorphism of Chloroplast DNA and Phylogeography of Green Alder (Alnus alnobetula (Ehrh.) K. Koch s. l.) in Asiatic Russia

This paper studies the phylogeography of Alnus alnobetula s. l. in the Asian part of the Russian range with the use of chloroplast DNA (cpDNA) sequences (intergenic spacers trnH-psbA, trnS-trnG, and

Karyotype Analysis of Alnus Mill. (Betulaceae) Species Originating From Northeastern Asia

It is concluded that the center origin of Alnus spp.

Alnus subgenus Alnus in the Eocene of western North America based on leaves, associated catkins, pollen, and fruits.

The Clarno fossils are most similar to the extant North American species of subgenus Alnus rather than to those from Asia and Europe, indicating that this modern subgenu was already distinct by the middle Eocene and that the intercontinental migration likely occurred earlier.

Phylogeny and Historical Biogeography of the Genus Platanus as Inferred From Nuclear and Chloroplast DNA

Phylogenetic analyses of DNA sequences of six species of Platanus were conducted to estimate species relationships and analyze biogeographic history, and the root node for the genus was confirmed to fall between subg.

Species identification of Alnus (Betulaceae) using nrDNA and cpDNA genetic markers

The combination of two regions, ITS and trnH‐psbA, is the best choice for DNA identification of Alnus species, as an improvement and supplement for morphologically based taxonomy and suggests a relatively reliable and open taxonomic system based on the linked DNA and morphological data.

The phylogenetic results indicate a generalized biogeographic track between southeastern Europe and eastern Asia and one clade of Ostrya in the ITS tree, although discordance is found in the morphological data concerning this biogeographical relationship.

Phylogeny and evolution of the Betulaceae as inferred from DNA sequences, morphology, and paleobotany.

Phylogenetic relationships among the extant genera deduced by these analyses are compatible with inferences from ecological evolution and the extensive fossil record.

Complete congruence between morphological and rbcL-based molecular phylogenies in birches and related species (Betulaceae).

The topologies obtained by the different methods were completely congruent, and bootstrapping strongly supported the division of the family Betulaceae into two major clades, Betuleae (Alnus and Betula) and Coryleae (other members).

Phylogenetic Relationships of Corylus Species (Betulaceae) Based on Nuclear Ribosomal DNA ITS Region and Chloroplast matK Gene Sequences

A classification based on matK sequences was not in agreement with currently accepted taxonomic classification, and the paucity of informative characters precludes more definitive inferences from the matK data.

Timing the eastern Asian-eastern North American floristic disjunction: molecular clock corroborates paleontological estimates.

The results suggest that the isolation of most morphologically similar disjunct species in eastern Asia and eastern North America occurred during the global climatic cooling period that took place throughout the late Tertiary and Quaternary.

Paraphyletic Syringa (Oleaceae): Evidence from Sequences of Nuclear Ribosomal DNA ITS and ETS Regions

Abstract Sequences of nuclear ribosomal DNA ITS and ETS regions were used to examine phylogenetic relationships of Syringa and Ligustrum. Twenty-seven samples were included in parsimony analyses,

For the establishment of floristic sequences, pollen and spore fioras from the Late Cretaceous sediments ranging from Cenomanian to Maestrichtian of northern Japan are studied. Four areas where the

Cytological Studies in the Betulaceae. II. Coryolus and Alnus

Corylus exhibits no polyploidy, all species and hybrids having the haploid number of fourteen chromosomes, while Alnus shows marked hybrid cytological characters and is considered to be heterozygous.

Phylogenetic, molecular, geologic, and fossil data all support the hypothesis that the eastern Asian and eastern North American disjunct distributions are relicts of the maximum development of temperate forests in the northern hemisphere.

Alnus maritima: a rare woody species from the New World

Although first introduced into cultivation in the 1870's and praised for its ornamental character, Alnus maritima (Marsh.) Muhl. ex Nutt. (seaside alder) remains a rare woody species with unrealised
