Abstract Random Amplified Polymorphic DNA (RAPD) and Inter-Simple Sequence Repeats (ISSR) markers were employed to examine samples from Quercus cerris, Q. suber and Q. crenata in order to test the hypothesis of the hybrid origin of Q. crenata from Q. cerris and Q. suber in a part of its distribution area where the two putative parents do not overlap at present. Leaves from 21 Q. crenata and 37 Q. cerris individual trees were collected at natural sites in northern Italy, where Q. suber is… 
Morphometric analyses of the leaf variation within Quercus L. sect. Cerris Loudon in Turkey.
TLDR
This study is the first to show the discrimination of species in Cerris section based on leaf characters from Turkey, and it showed that the leaf characters presented a good discrimination of five Cerris taxa in PCA at the population level.
Quercus crenata – the correct if long-forgotten name of the hybrid Quercus cerris × Quercus suber
TLDR
A thorough examination of the types and protologues of all relevant names leads to the conclusion that Q. × crenata Lam.
Morphological and molecular analysis of natural hybrids between the diploid Centaurea aspera L. and the tetraploid C. seridis L. (Compositae)
TLDR
The genetic analyses confirm that C. × subdecurrens is a result of the hybridisation between Centaurea aspera ssp.
Genetic differentiation of Allium sibiricum L. populations in Poland based on their morphological and molecular markers
TLDR
Inter simple sequence repeat DNA (ISSR) and morphological analyses were conducted to study the biogeographical relationships between geographically disjunctive populations of A. sibiricum in the Carpathians and Sudetes and showed a relatively high level of genetic similarity in specimens within certain groups of the Sudete and Carpathian populations.
Comparative systematics and phylogeography of Quercus Section Cerris in western Eurasia: inferences from plastid and nuclear DNA variation
TLDR
A first comprehensive taxonomic and phylogeographic scheme of western Eurasian members of sect.
Preliminary genetic approach based on both cytogenetic and molecular characterisations of nine oak species
TLDR
Nine Quercus species are characterised at cytogenetic and molecular levels to evaluate the ribosomal RNA genes expression, and to determine the physical mapping of the rDNA loci using both salt‐nylon silver staining and double‐target fluorescent in situ hybridisation techniques.
Influence of Relictual Species on the Morphology of a Hybridizing Oak Complex: An Analysis of the Quercus X Undulata Complex in the Four Corners Region
TLDR
It was found that, though common, hybridization seems to act at very restricted spatial scales and not in the production of a region-wide hybrid swarm, and most hybridization occurs between the predominant Q. gambelii and Q. turbinella.
Oak ribosomal DNA: characterization by FISH and polymorphism assessed by IGS PCR–RFLP
TLDR
Globally, IGS PCR–RFLP proved their usefulness for DNA fingerprinting, evaluation of phylogenies and genetic structure, proving to be an adequate complementary tool for rDNA based studies in genus Quercus.
Similarity analysis between species of the genus Quercus L. (Fagaceae) in southern Italy based on the fractal dimension
TLDR
The fractal dimension is calculated for seven species of the genus Quercus L. in Calabria region (southern Italy), five of which have a marcescent-deciduous and two a sclerophyllous character and is considered a useful tool for studying similarities amongst species.
Genetic diversity of Salixlapponum populations in Central Europe
Abstract Salixlapponum is a cold-tolerant relict species in Europe that occurs in several sites, probably reflecting previous migration routes of S.lapponum during the Pleistocene. However, only a

Endemic North African Quercus afares Pomel originates from hybridisation between two genetically very distant oak species (Q. suber L. and Q. canariensis Willd.): evidence from nuclear and cytoplasmic markers
TLDR
It is shown that Quercus afares is genetically, morphologically and ecologically differentiated from its parental species, and can therefore be considered as a stabilised hybrid species.
Morphological and Molecular Differentiation between Quercus petraea(Matt.) Liebl. and Quercus pubescens Willd. (Fagaceae) in Northern and Central Italy
TLDR
In the present study morphoanatomical and molecular traits were investigated in an attempt to characterize and to discriminate between these two oak species.
Differentiation and hybridization between Quercus crispula and Q. dentata (Fagaceae): insights from morphological traits, amplified fragment length polymorphism markers, and leafminer composition.
TLDR
Morphological traits and Phyllonorycter composition differ enough in these two oak species to be useful for identification of species and hybrids, but AFLP data are less informative because the degree of molecular differentiation between the two species is low.
Genetic Differentiation of Pedunculate Oak Quercus robur L. in the European Part of Russia Based on RAPD Markers
TLDR
Using randomly amplified polymorphic DNA markers (RAPD), genetic variation and differentiation in four populations of pedunculate oak Quercus robur L. were examined and failed to reveal population-specific DNA fragments for any primer although the frequencies of 14 fragments were significantly different among populations.
Morphological and RAPD analysis of hybridization between Quercus affinis and Q. laurina (fagaceae), two Mexican red oaks.
TLDR
Foliar variation followed a partially congruent pattern, but Q. laurina-like morphology predominated in some of the genetically intermediate populations, consistent with a hypothesis of secondary contact between the two oak species that has resulted in some differential introgression among markers.
Genetic variation and differentiation of populations within the Quercus affinis Quercus laurina (Fagaceae) complex analyzed with RAPD markers
TLDR
The population genetics of two hybridizing Mexican red oaks was investigated with 54 randomly amplified polymorphic DNA (RAPD) markers scored in 415 individuals representing the distribution area of the two species and a probable secondary hybrid zone, confirming a significant association between geographic and genetic distances among populations.
AFLP markers demonstrate local genetic differentiation between two indigenous oak species [Quercus robur L. and Quercus petraea (Matt.) Liebl.] in Flemish populations
TLDR
Analysis of the genetic structure showed that the divergence between species, as observed by ordination, was significant and a smaller though significant differentiation was also revealed for both species among populations within species.
Frequent cytoplasmic exchanges between oak species that are not closely related: Quercus suber and Q. ilex in Morocco
TLDR
In mixed‐species populations, cytoplasmic genomes were frequently shared across species, as indicated by an introgression ratio of 0.63, a new measure of the propensity of species to share locally genetic markers, varying from zero (complete differentiation) to one (no differentiation).
Asymmetrical introgression between two Morus species (M. alba, M. rubra) that differ in abundance
TLDR
The results suggest that introgression is bidirectional but asymmetrical and is related, in part, to the relative frequency of parental taxa.
Genetic structure of hybrid zones between Pinus pumila and P. parviflora var. pentaphylla (Pinaceae) revealed by molecular hybrid index analysis.
TLDR
Codominant nuclear DNA markers diagnostic or mostly diagnostic for each parental species by single-strand conformation polymorphism of polymerase chain reaction (PCR) products, using expressed sequence tag (EST) primers of Pinus taeda are developed.
