THE PERIDERM DEVELOPMENT IN QUERCUS SUBER
IAWA Journal, 2004In the cork oak (Quercus suber L.), the phellogen differentiates during the first year of growth in the cell layer immediately under the epidermis and divides to form 3–6 suberized phellem cells. Division of the phellogen only occurs after suberization of the previous divided cell.

Cork Oak Trees (Quercus suber L.)
2006A transformation system for selected mature Quercus suber L. trees using Agrobacterium tumefaciens has been established. Embryos obtained from recurrent proliferating embryogenic masses are inoculated with AGL1 strain harbouring the plasmid pBINUbiGUSint, which carries the nptII and uidA genes.

Antimutagenicity of a suberin extract from Quercus suber cork
Mutation Research/Genetic Toxicology and Environmental Mutagenesis, 1999The 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.

Temperature stress effects in Quercus suber leaf metabolism
Journal of Plant Physiology, 2011Based on projections that climate changes are will intensify in the near future, it is important to understand how plants respond to climate. Consequently, we have been studying the effect of contrasting temperatures on leaf metabolism of Quercus suber, an important Mediterranean oak.

Ecological behavior of Quercus suber and Quercus ilex inferred by topographic wetness index (TWI)
Trees, 2013The ecological behaviors of a network of pure evergreen oak stands (Quercus suber L. and Quercus ilex L.) in the Central-Western Mediterranean Basin were investigated toward climatic and edaphic factors implemented with the application of topographic wetness index (TWI).

Immunolocalization of AGPs and Pectins in Quercus suber Gametophytic Structures
2017The arabinogalactan proteins (AGPs) are highly glycosylated proteins, ubiquitous in plants that have been linked to numerous aspects of sexual reproduction in several plant species, including the monoecious tree species Quercus suber. AGPs are found in cell membranes and cell walls of all types of tissues, including reproductive cells and organs ...

Micropropagation of juvenile and adult Quercus suber L.
Plant Cell, Tissue and Organ Culture, 1990This paper describes research on the application of tissue culture techniques to the micropropagation of cork oak (Quercus suber L.), a forest species of ecological and industrial importance in the Mediterranean area. Apical buds and nodal stem segments were employed as initial explants.
