Cork Oak Trees (Quercus suber L.)

2006
A 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.

Shoot development in Quercus suber L. somatic embryos

In Vitro Cellular & Developmental Biology - Plant, 2002
N6-Benzyladenine (BA; 0.04–4μM) application to germinated Quercus suber somatic embryos considerably increased caulinar apex elongation frequency and maintained active growth in the plantlets, although it did not have a significant effect on the percentage of shoots with normal morphology.

Micropropagation of juvenile and adult Quercus suber L.

Plant Cell, Tissue and Organ Culture, 1990
This 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.

Shrubland management to promote Quercus suber L. establishment

Forest Ecology and Management, 2008
Shrubs often dominate early successional stages in areas that are suitable for the establishment of forests. Under a dense shrub canopy, the density of seedlings of late successional tree species can be low, suggesting that colonisation by forest species may be hampered.

Improved Genetic Transformation of Cork Oak (Quercus suber L.)

2012
An Agrobacterium-mediated transformation system for selected mature Quercus suber L. trees has been established. Leaf-derived somatic embryos in an early stage of development are inoculated with an AGL1 strain harboring a kanamycin-selectable plasmid carrying the gene of interest.

Somatic and Gamatic Embryogenesis in Quercus Suber L.

2000
Cork-oak (Quercus suber L., order Fagales, family Fagaceae) belongs to a group of forest species of outstanding importance in the Boreal hemisphere. Oaks are the dominant species in many ecosystems of the Holartic region.

Cork Oak Quercus suber L. Embryogenic Liquid Cultures

2018
The cork oak is an evergreen tree species typical of Mediterranean forests. It grows in dense stands but also in low density, in the savanna-like system called “dehesa” in Spain and “montado” in Portugal. The most characteristic production of Quercus suber is cork, although acorn crops are also important for feeding pigs of the Iberian race.

The Cellular Structure of Cork from Quercus Suber L.

IAWA Journal, 1987
The main characteristics of the cellular structure of cork from Quercus suber L. are reviewed and complt;mented with new observations of virgin and reproduction cork by scanning electron microscopy. Particular emphasis is given to cell geometry and topology and to the corrugations that are observed in the cell walls.

Trabeculae in the Cork Cells of Quercus Suber L.

IAWA Journal, 1989
Trabeculae were observed in the cork tissue of Quercus suber L. They extended radially between tangential walls across a few cells, with a rod-like fonn, and were found to follow the undulation of the radial walls of the cork cells.

Quercus suber L. - hrast plutnjak

2016
Quercus suber L. (porodica Fagaceae, sekcija Cerris), hrast plutnjak, jedna je od najvažnijih drvenastih biljaka na području zapadnoga Mediterana. Plutnjak je dugovječno, vazdazeleno drveće, visoko do 20 m. Najznačajnija i najprepoznatljivija karakteristika ove vrste je debela, plutasta kora, po kojoj je i dobila ime.
