In this work we studied the genome organization and evolution within the family, by karyotyping and physically mapping rDNA in ten European and Asian species of the genera Fagus, Quercus, and Castanea. All of the species studied had a chromosome number of 2n=2x=24, except for the first report of a single individual of Quercus suber which proved to be triploid (2n=3x=36). The rDNA physical mapping revealed several patterns: the dominant one is present in European and Asian Quercus subgenus Quercus, and in Castanea sativa and Castanea crenata, consisting of two 18S–25S rDNA loci (one subterminal major and one pericentromeric minor) and one 5S rDNA pericentromeric locus. In Fagus sylvatica and in Quercus sessilifolia, different patterns were observed: four terminal 18S–25S rDNA loci and two 5S rDNA pericentromeric loci in the former, and five 18S–25S rDNA loci (three terminal and two intercalary) and one 5S rDNA pericentromeric locus in the latter. In Castanea mollissima a distinct rDNA distribution pattern with two intercalary 18S–25S rDNA loci and two 5S rDNA was found. These findings suggest rDNA loci restructuring during Castanea evolution, and variability of 18S–25S loci between Quercus and Cyclobalanopsis subgenera.</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%">Arenal, Francisco</style></author><author><style face="normal" font="default" size="100%">Platas, Gonzalo</style></author><author><style face="normal" font="default" size="100%">Pelaez, Fernando</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">A new endophytic species of Preussia (Sporormiaceae) inferred from morphological observations and molecular phylogenetic analysis</style></title><secondary-title><style face="normal" font="default" size="100%">FUNGAL DIVERSITY</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Ascomycota</style></keyword><keyword><style  face="normal" font="default" size="100%">Bayesian analysis</style></keyword><keyword><style  face="normal" font="default" size="100%">elongation factor</style></keyword><keyword><style  face="normal" font="default" size="100%">ITS</style></keyword><keyword><style  face="normal" font="default" size="100%">LSU</style></keyword><keyword><style  face="normal" font="default" size="100%">maximum likelihood</style></keyword><keyword><style  face="normal" font="default" size="100%">phylogeny</style></keyword><keyword><style  face="normal" font="default" size="100%">rDNA</style></keyword><keyword><style  face="normal" font="default" size="100%">Spain</style></keyword><keyword><style  face="normal" font="default" size="100%">Sporormiaceae</style></keyword><keyword><style  face="normal" font="default" size="100%">taxonomy</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2007</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2007///</style></date></pub-dates></dates><volume><style face="normal" font="default" size="100%">25</style></volume><pages><style face="normal" font="default" size="100%">1 - 17</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">A new species of Preussia as an endophyte of different typical Mediterranean plant species is newly described and illustrated based on molecular and morphological features. Preussia mediterranea resembles P. australis, P. africana and P. similis from a morphological point of view, but appeared closer to P. minima and P. isabellae by molecular analysis. Phylogenetic analysis of the entire ITS region combined with the D1-D2 domains of the 28S rRNA gene, and a fragment of the elongation factor EF-1 alpha gene, using Maximum Likelihood and a Bayesian Markov Chain Monte Carlo approach, generally resulted in statistically well-supported clades for all the species studied. Morphological data and molecular phylogenetic analysis supported the recognition of the new taxon.</style></abstract><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;pub-location: NORTHEAST FORESTRY UNIV, HARBIN, 00000, PEOPLES R CHINA&lt;br/&gt;publisher: FUNGAL DIVERSITY PRESS</style></notes></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%">Alves, Artur</style></author><author><style face="normal" font="default" size="100%">Phillips, Alan J L</style></author><author><style face="normal" font="default" size="100%">Henriques, Isabel</style></author><author><style face="normal" font="default" size="100%">Correia, António</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Evaluation of amplified ribosomal DNA restriction analysis as a method for the identification of Botryosphaeria species.</style></title><secondary-title><style face="normal" font="default" size="100%">FEMS microbiology letters</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">ARDRA</style></keyword><keyword><style  face="normal" font="default" size="100%">Botryosphaeria</style></keyword><keyword><style  face="normal" font="default" size="100%">D1/D2 domains</style></keyword><keyword><style  face="normal" font="default" size="100%">ITS</style></keyword><keyword><style  face="normal" font="default" size="100%">rDNA</style></keyword><keyword><style  face="normal" font="default" size="100%">Species identification</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2005</style></year></dates><volume><style face="normal" font="default" size="100%">245</style></volume><pages><style face="normal" font="default" size="100%">221-229</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The polymerase chain reaction was used to amplify a rDNA fragment containing the internal transcribed spacers (ITS1-5.8S-ITS2) and the D1/D2 variable domains of the 28S rDNA from 10 species of the genus Botryosphaeria (Fungi, Ascomycota). Restriction analysis of the amplicons with frequent-cutting endonucleases (amplified ribosomal DNA restriction analysis) allowed the definition of 12 rDNA haplotypes. Each of the rDNA haplotypes could be unambiguously assigned to a single Botryosphaeria species, thus allowing clear identification of all the species tested. Intraspecific polymorphism was very low and detected only in Botryosphaeria parva and Botryosphaeria dothidea. Cluster analysis of banding patterns of the isolates corresponded well with known species delineations.
