A previous molecular approach identiﬁed a list of genes potentially important for cork formation and differentiation, providing a new basis for further molecular studies. This report is the ﬁrst molecular characterization of one of these candidate genes, QsMYB1, coding for an R2R3-MYB transcription factor. The R2R3-MYB gene sub-family has been described as being involved in the phenylpropanoid and lignin pathways, both involved in cork biosynthesis. The results showed that the expression of QsMYB1 is putatively mediated by an alternative splicing (AS) mechanism that originates two different transcripts (QsMYB1.1 and QsMYB1.2), differing only in the 5 -untranslated region, due to retention of the ﬁrst intron in one of the variants. Moreover, within the retained intron, a simple sequence repeat (SSR) was identiﬁed. The upstream regulatory region of QsMYB1 was extended by a genome walking approach, which allowed the identiﬁcation of the putative gene promoter region. The relative expression pattern of QsMYB1 transcripts determined by reverse transcription quantitative polymerase chain reaction (RTqPCR) revealed that both transcripts were up-regulated in cork tissues; the detected expression was several times higher in newly formed cork harvested from trees producing virgin, second or reproduction cork when compared with wood. Moreover, the expression analysis of QsMYB1 in several Q. suber organs showed very low expression in young branches and roots, whereas in leaves, immature acorns or male ﬂowers, no expression was detected. These preliminary results suggest that QsMYB1 may be related to secondary growth and, in particular, with the cork biosynthesis process with a possible alternative splicing mechanism associated with its regulatory function.</style></abstract><issue><style face="normal" font="default" size="100%">2</style></issue><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;accession-num: 23218545</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%">Olivella, Maria À</style></author><author><style face="normal" font="default" size="100%">Jové, Patrícia</style></author><author><style face="normal" font="default" size="100%">Oliveras, Anna</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">The use of cork waste as a biosorbent for persistent organic pollutants–Study of adsorption/desorption of polycyclic aromatic hydrocarbons</style></title><secondary-title><style face="normal" font="default" size="100%">Journal of Environmental Science and Health, Part A</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Adsorption</style></keyword><keyword><style  face="normal" font="default" size="100%">Aromatic</style></keyword><keyword><style  face="normal" font="default" size="100%">Aromatic: chemistry</style></keyword><keyword><style  face="normal" font="default" size="100%">biosorbent</style></keyword><keyword><style  face="normal" font="default" size="100%">Chemical</style></keyword><keyword><style  face="normal" font="default" size="100%">Chemical: chemistry</style></keyword><keyword><style  face="normal" font="default" size="100%">Cork waste</style></keyword><keyword><style  face="normal" font="default" size="100%">Environmental Remediation</style></keyword><keyword><style  face="normal" font="default" size="100%">Environmental Remediation: methods</style></keyword><keyword><style  face="normal" font="default" size="100%">Gas Chromatography-Mass Spectrometry</style></keyword><keyword><style  face="normal" font="default" size="100%">Lignin</style></keyword><keyword><style  face="normal" font="default" size="100%">Lignin: chemistry</style></keyword><keyword><style  face="normal" font="default" size="100%">Lipids</style></keyword><keyword><style  face="normal" font="default" size="100%">Lipids: chemistry</style></keyword><keyword><style  face="normal" font="default" size="100%">organic pollutants</style></keyword><keyword><style  face="normal" font="default" size="100%">PAHs</style></keyword><keyword><style  face="normal" font="default" size="100%">Polycyclic Hydrocarbons</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus: chemistry</style></keyword><keyword><style  face="normal" font="default" size="100%">Solid Phase Microextraction</style></keyword><keyword><style  face="normal" font="default" size="100%">sorption-desorption</style></keyword><keyword><style  face="normal" font="default" size="100%">Time Factors</style></keyword><keyword><style  face="normal" font="default" size="100%">Water Pollutants</style></keyword><keyword><style  face="normal" font="default" size="100%">water treatment</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2011</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2011///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://www.tandfonline.com/doi/abs/10.1080/10934529.2011.579845http://www.ncbi.nlm.nih.gov/pubmed/21644164</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">46</style></volume><pages><style face="normal" font="default" size="100%">824 - 832</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The aim of this study is to determine the sorption-desorption behavior of a mixture of thirteen aqueous PAHs on cork waste at a particle of size 0.25?0.42 mm obtained from the remains of cork strips. The final purpose is to use this natural adsorbent as an alternative to activated carbon in an innovative approach for the removal of this class of toxic compounds, and significantly reduce the regeneration costs of the process. The chemical composition of the selected cork revealed that suberin (38.5 %) and lignin (31.6 %) were the main structural components of the cell wall. The high efficiency of cork as a biosorbent of PAHs is shown by the fact that just over 80 % of adsorption occurred during the first two minutes of contact time. Both Freundlich's and Langmuir's isotherms gave good fits to the sorption process. The highest adsorption affinities were exhibited for pyrene, anthracene, and phenanthrene. Desorption studies indicate a high degree of irreversibility for all PAHs, and especially so in the case of high molecular PAHs. The correlation with KF and low molecular weight PAHs was the most significant. The quantity of cork required to reduce water pollution was estimated to be between 3 and 15 times less than the quantities required in the case of other materials (i.e. aspen wood and leonardite). This study demonstrates for the first time that cork is a potential biosorbent for PAHs and may have relevance in the future treatment of PAH-contaminated waters.</style></abstract><issue><style face="normal" font="default" size="100%">8</style></issue><notes><style face="normal" font="default" size="100%">From Duplicate 1 (The use of cork waste as a biosorbent for persistent organic pollutants–Study of adsorption/desorption of polycyclic aromatic hydrocarbons - Olivella, Maria À; Jové, Patrícia; Oliveras, Anna)From Duplicate 1 (The use of cork waste as a biosorbent for persistent organic pollutants–Study of adsorption/desorption of polycyclic aromatic hydrocarbons - Olivella, Maria À; Jové, Patrícia; Oliveras, Anna)The following values have no corresponding Zotero field:&lt;br/&gt;publisher: Taylor &amp; Francis&lt;br/&gt;accession-num: 21644164</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%">Sanz-Pérez, V</style></author><author><style face="normal" font="default" size="100%">Castro-Diez, P</style></author><author><style face="normal" font="default" size="100%">Valladares, F</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Differential and interactive effects of temperature and photoperiod on budburst and carbon reserves in two co-occurring Mediterranean oaks</style></title><secondary-title><style face="normal" font="default" size="100%">Plant Biology</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Global warming</style></keyword><keyword><style  face="normal" font="default" size="100%">Lipids</style></keyword><keyword><style  face="normal" font="default" size="100%">Phenology</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus faginea</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus ilex</style></keyword><keyword><style  face="normal" font="default" size="100%">soluble sugars</style></keyword><keyword><style  face="normal" font="default" size="100%">starch</style></keyword><keyword><style  face="normal" font="default" size="100%">wood anatomy</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2009</style></year></dates><publisher><style face="normal" font="default" size="100%">Blackwell Publishing Ltd</style></publisher><volume><style face="normal" font="default" size="100%">11</style></volume><pages><style face="normal" font="default" size="100%">142-151</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Effects of temperature and photoperiod and their interactions on budburst and on the use of carbon reserves were examined in two Mediterranean oaks differing in wood anatomy and leaf habit.

ESI-MS analysis of the methanolysate showed, besides the aliphatic monomers, suberin oligomers, including linear dimeric esters of α,?-diacids and ?-hydroxyacids. Two types of dimeric esters were identified:? a α,?-diacid linked to a ?-hydroxyacid and two inter-linked ?-hydroxyacids. The α,?-diacids and ?-hydroxyacids found as monomer residues in the dimeric esters were mainly the C18 monomers with midchain substituents. The identification of these dimeric esters was based in their CID-MS/MS spectra and confirmed after synthesis of model compounds.

The observed variation of the fatty acid content of abdominal fat of acorn-fed chickens requires further research on the precise nutrient digestibility of oak acorns before considering them as a potential feed.</style></abstract><issue><style face="normal" font="default" size="100%">4</style></issue></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%">Krizková, L</style></author><author><style face="normal" font="default" size="100%">Lopes, M H</style></author><author><style face="normal" font="default" size="100%">Polónyi, J</style></author><author><style face="normal" font="default" size="100%">Belicová, a</style></author><author><style face="normal" font="default" size="100%">Dobias, J</style></author><author><style face="normal" font="default" size="100%">Ebringer, L</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Antimutagenicity of a suberin extract from Quercus suber cork.</style></title><secondary-title><style face="normal" font="default" size="100%">Mutation research</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Acridine Orange</style></keyword><keyword><style  face="normal" font="default" size="100%">Acridine Orange: toxicity</style></keyword><keyword><style  face="normal" font="default" size="100%">Animals</style></keyword><keyword><style  face="normal" font="default" size="100%">Antimutagenic Agents</style></keyword><keyword><style  face="normal" font="default" size="100%">Antimutagenic Agents: pharmacology</style></keyword><keyword><style  face="normal" font="default" size="100%">Euglena gracilis</style></keyword><keyword><style  face="normal" font="default" size="100%">Euglena gracilis: drug effects</style></keyword><keyword><style  face="normal" font="default" size="100%">Euglena gracilis: genetics</style></keyword><keyword><style  face="normal" font="default" size="100%">Euglena gracilis: radiation effects</style></keyword><keyword><style  face="normal" font="default" size="100%">Lipids</style></keyword><keyword><style  face="normal" font="default" size="100%">Membrane Lipids</style></keyword><keyword><style  face="normal" font="default" size="100%">Membrane Lipids: pharmacology</style></keyword><keyword><style  face="normal" font="default" size="100%">Mutagenicity Tests</style></keyword><keyword><style  face="normal" font="default" size="100%">Mutagenicity Tests: methods</style></keyword><keyword><style  face="normal" font="default" size="100%">Mutagens</style></keyword><keyword><style  face="normal" font="default" size="100%">Mutagens: toxicity</style></keyword><keyword><style  face="normal" font="default" size="100%">Ofloxacin</style></keyword><keyword><style  face="normal" font="default" size="100%">Ofloxacin: toxicity</style></keyword><keyword><style  face="normal" font="default" size="100%">Plant Extracts</style></keyword><keyword><style  face="normal" font="default" size="100%">Plant Extracts: pharmacology</style></keyword><keyword><style  face="normal" font="default" size="100%">Plant Shoots</style></keyword><keyword><style  face="normal" font="default" size="100%">Plant Shoots: chemistry</style></keyword><keyword><style  face="normal" font="default" size="100%">Spectrophotometry, Ultraviolet</style></keyword><keyword><style  face="normal" font="default" size="100%">Superoxides</style></keyword><keyword><style  face="normal" font="default" size="100%">Superoxides: metabolism</style></keyword><keyword><style  face="normal" font="default" size="100%">Trees</style></keyword><keyword><style  face="normal" font="default" size="100%">Trees: chemistry</style></keyword><keyword><style  face="normal" font="default" size="100%">Ultraviolet Rays</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1999</style></year></dates><volume><style face="normal" font="default" size="100%">446</style></volume><pages><style face="normal" font="default" size="100%">225-30</style></pages><isbn><style face="normal" font="default" size="100%">4217542577</style></isbn><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The possible protective effect of a suberin extract from Quercus suber cork on acridine orange (AO)-, ofloxacin- and UV radiation-induced mutagenicity (bleaching activity) in Euglena gracilis was examined. To our knowledge, the present results are the first attempt to analyse suberin in relation to mutagenicity of some chemicals. Suberin exhibits a significant dose-dependent protective effect against AO-induced mutagenicity and the concentration of 500 micrograms/ml completely eliminates the Euglena-bleaching activity of AO. The mutagenicity of ofloxacin is also significantly reduced in the presence of suberin (125, 250 and 500 micrograms/ml). However, the moderate protective effect of suberin on UV radiation-induced mutagenicity was observed only at concentrations 500 and 1000 micrograms/ml. Our data shows that suberin extract from Q. suber cork possess antimutagenic properties and can be included in the group of natural antimutagens acting in a desmutagenic manner.</style></abstract><accession-num><style face="normal" font="default" size="100%">10635345</style></accession-num></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%">Almendros, G</style></author><author><style face="normal" font="default" size="100%">Sanz, J</style></author><author><style face="normal" font="default" size="100%">VELASCO, F</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Signatures of lipid assemblages in soils under continental Mediterranean forests</style></title><secondary-title><style face="normal" font="default" size="100%">European Journal of Soil Science</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">GC-MS</style></keyword><keyword><style  face="normal" font="default" size="100%">Lipids</style></keyword><keyword><style  face="normal" font="default" size="100%">Lipids assemblage (voyant)</style></keyword><keyword><style  face="normal" font="default" size="100%">mediterranean forest soils</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1996</style></year></dates><publisher><style face="normal" font="default" size="100%">Blackwell Publishing Ltd</style></publisher><volume><style face="normal" font="default" size="100%">47</style></volume><pages><style face="normal" font="default" size="100%">183-196</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The analysis of free lipids in 12 soils from three representative types of Mediterranean forest has been carried out in an attempt to describe diagnostic molecules reflecting differences between the ecosystems and the intensity of the soil organic matter turnover.

Waxes and other soluble components of cork begin to decompose at ca. 150 degrees C. This is accompanied by partial decomposition of suberin, probably initiated at the points of attachment to the cell wall. The carbohydrates begin to decompose at ca. 200 degrees C. The decomposition of lignin begins at 250-300 degrees C, while suberin undergoes further degradation. Significant amounts of coke are formed in the process. At 400 degrees C cork has been transformed into coke with traces of partially decomposed suberin. The thermal decomposition of cork is dependent on the calcination time, particularly in the 200-350 degrees C range.</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;accession-num: 7773647</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%">González-Vila, F L</style></author><author><style face="normal" font="default" size="100%">Almendros, G</style></author><author><style face="normal" font="default" size="100%">Martin, F</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">An evaluation of the differences in the composition of humic acids in soils under oak and pine forest by GC-MS after mild degradation</style></title><secondary-title><style face="normal" font="default" size="100%">Plant and soil</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Forest soils</style></keyword><keyword><style  face="normal" font="default" size="100%">humic acids</style></keyword><keyword><style  face="normal" font="default" size="100%">Lipids</style></keyword><keyword><style  face="normal" font="default" size="100%">mild degradation</style></keyword><keyword><style  face="normal" font="default" size="100%">Pinus</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus</style></keyword><keyword><style  face="normal" font="default" size="100%">resin acids</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1987</style></year></dates><volume><style face="normal" font="default" size="100%">103</style></volume><pages><style face="normal" font="default" size="100%">83-88</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Significant differences were found in the products released after eight samples of humic acids (HA's) isolated from soils under mediterranean pine and oak forests underwent mild degradation.

The aliphatic constituents were more firmly retained in the HA's under oak, which presented mean values for aromatic acids lower than the humic samples from pine forests. Different types of diterpene resin acids were also found amongst the mild degradation products of HA's from the studied areas.</style></abstract></record></records></xml>
