Ruscus aculeatus L. species is protected both at national and European level (trough Habitats Directive of EU and Bern Convention). The aspects of in vitro morphogenesis through all the stages from inoculation, multiplication to rooting and acclimatization have been studied. In order to long term conservation and multiplication or to exploit somaclonal variation induced by in vitro technique is required the identification of some biochemical or molecular markers for fast evaluation of regenerants. In this respect, genetic stability or variability of Ruscus aculeatus plants collected from three populations and regenerants obtained in vitro culture was estimated by electrophoretical methods. Therefore, zymograms of different enzymes as esterase, acid and alkaline phosphatase, glutamate-oxaloacetate transferase, malate dehydrogenase and peroxidase were analyzed. The expression of esterases, phosphatases, malate dehydrogenases displayed changes in correlation with growth condition, while the peroxidases pattern was more stabile in natural population as well as in vitro regenerated plantlet."

Influence of microstructured carbon materials on Sequoia sempervirens (D. Don.) Endl. in vitro culture / Raluca Stoiculescu in Annals of forest research, vol 52 n° 1 (January 2009)

Langues : Anglais (eng) Descripteur : [Termes IGN] carbone [Termes IGN] microbouturage [Termes IGN] Sequoia sempervirens Résumé : (Auteur) "The present experimental research has been mainly focused on Sequoia sempervirens (D. Don.) Endl. as woody plant model system, for testing the influence of some microstructured carbon materials (CCM) comparing with the activated charcoal action, on the in vitro growth. The work hypothesis was that CCM can induce effects on the plant culture, similar to those induced by activated charcoal, due to their high absorption capacity. The influence of two types CCM and activated charcoal introduced in the medium culture was evaluated on the fresh weight and on the length of the in vitro regenerants, after 30 and 60 days of cultivation. Our data revealed that the CCM is not toxic and does not inhibit plant growth. We also remarked that S. sempervirens (D. Don.) Endl. was more reactive to the activated charcoal into the nutritive medium than the CCM compounds. The use of these new microstructured compounds is an important step both in the study of materials science and in the field of plant biotechnologies."
