Phylogeographical variation of chloroplast DNA in cork oak (Quercus suber).
BACKGROUND AND AIMS In the last decades, the geographical location of the centre of origin of Quercus suber (cork oak), a strictly western Mediterranean oak species, has been the subject of controversy. METHODS RFLP variation over the whole chloroplast DNA molecule and PCR-RFLPs over seven specific cpDNA fragments were analysed phylogeographically to reconstruct the evolutionary history of co...
متن کاملDeciphering cork formation in Quercus suber
The family of Fagaceae, comprises about 900 species, among them the best-known group of this family is the oaks, genus Quercus, that are commonly used as timber or for cork production. Cork is produced by Q. suber, an evergreen oak with major economic and environmental importance for Mediterranean region, in particular for Portugal that is the leading producer of this material. Besides, the eco...
متن کاملDiurnal changes in photoprotective mechanisms in leaves of cork oak (Quercus suber) during summer.
Daily variations in photoprotective mechanisms were studied in sun and shade leaves of 40-year-old cork oak (Quercus suber L.) trees during early summer in Portugal. Although trees were not severely water stressed because predawn leaf water potentials remained high, photosynthesis and stomatal conductance decreased at midday. The midday depression in gas exchange was not reversed by short-term ...
متن کاملCharacterization of the responses of cork oak (Quercus suber) to iron deficiency.
We studied responses of cork oak (Quercus suber L.) to iron (Fe) deficiency by comparing seedlings grown hydroponically in nutrient solution with and without Fe. Seedlings grown without Fe developed some responses typical of the Strategy I group of Fe-efficient plants, including two- and fourfold increases in plasma membrane ferric chelate reductase activity of root tips after 2 and 4 weeks of ...
متن کاملEffects of cadmium on cork oak (Quercus suber L.) plants grown in hydroponics.
Cork oak (Quercus suber L.) is an autochthonous tree species that is being used for reforestation in heavy-metal-contaminated areas in Spain. A hydroponics experiment was carried out to characterize the effects of Cd on several morphological and physiological parameters in this species, including shoot length, nutrient concentrations and allocation in different organs, leaf pigment concentratio...
