We investigated the discriminatory power of a subset of highly variable proposed plant barcoding loci (matK, trnH-psbA, ITS2) in Quercus, a taxonomically complex tree genus of global importance. The research included all currently recognized species and some major variants of the Mediterranean region and Europe (32 taxa) and 17 East Asian and North American species used for comparison. Based on sequence character state, we assigned unique plastid haplotypes to 40.8% of the investigated species; ITS2 increased the resolution up to 87.8% of total taxa. Nevertheless, unsuccessful genetic distance-based discrimination questioned the potential efficiency of correct species identification for future studies. Most species appeared to be nonmonophyletic in parallel phylogenetic tests. Three subgeneric groups were outlined, with different rates of within-group variability and geographical differentiation. Members of one of these groups (corresponding to the Eurasian Group Ilex) were paraphyletic to Group Quercus from the New and Old World and the Eurasian Group Cerris. The data gathered indicate that barcoding markers may help to identify closely related species clusters and contribute to the inference of major diversification and evolutionary patterns in oaks, but the methodology per se appears to be of limited efficacy in defining species limits, unless we make a profound revision of traditional Quercus taxonomic categories. © 2013 The Linnean Society of London, Botanical Journal of the Linnean Society, 2013, 00, 000–000.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Yilmaz, Aykut</style></author><author><style face="normal" font="default" size="100%">Uslu, Emel</style></author><author><style face="normal" font="default" size="100%">Babac, M Tekin</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Cytogenetic studies on Quercus L.

Chemical characteristics are studied, in comparison with otherr wood species: Pine (Pinus pinaster) and Eucalyptus (Eucalyptus globulus), in order to obtain wood cellulosic pulp for paper. The average firewood production of the ilex pruning corresponding to 1975-78 in Andalusia was of 78.000 T/year, with a practically uniform trend. A statistical analysis with ARMA pattern let us estimate a yearly averge production of ilex pruning firewood around 72.500 T/year for the 1999-2006 period, which could have an upward correction if the exploitation in all hoamoak woods was total. For the manufacture of cellulosic pulp from ilex pruning wood, it would be necessary to separte the cortex due to a lower content of holocellulose and alpha-cellulose and a higher content of soluble substances and lignin. The content of lignin of ilex pruning wood is lower than the one of other wood species like Pinus Pinaster (76,7%), Eucalyptus globulus (56,4%) and olive grove pruning (8%).</style></abstract></record></records></xml>
