Fleshy structures associated with the ovule/seed arose independently several times during gymnosperm evolution. are linked to protection and dispersal, present in all four lineages of extant gymnosperms. The ontogenetic origin fleshy could be different, spans from ovule funiculus Taxus baccata aril, integument Ginkgo biloba, modified bracts as case Ephedra species. This variability ontogeny is ...

Taxotere (RP 56976; NSC 628503; N-debenzoyl-N-tert-butoxycarbonyl-10-deacetyl taxol) is a new microtubule stabilizing agent. It is obtained by semisynthesis from a noncytotoxic precursor extracted from the needles of the tree, Taxus baccata L. Taxotere was evaluated for antitumor activity against a variety of transplantable tumors of mice. Taxotere had no marked schedule dependency and was foun...

In the gorge of Ročica creek in southwestern Julian Alps we documented (with phytosociological relevés and tables) six plant communities moist rock crevices nine forest shrub that belong four Natura 2000 habitat types. The studied is unique for stands syntaxa Astrantio carniolicae-Pinguiculetum alpinae var. Valeriana saxatilis, Palustriello commutati-Veronicetum urticifolia, Veronico urticifoli...

Paclitaxel is a highly functionalized diterpenoid that broadly used for the treatment of several cancer types. This valuable specialized metabolite naturally exists in inner bark Taxus species low amounts. The limited-scale production paclitaxel cell cultures has necessitated use elicitors. Recently, methyl-?-cyclodextrin (CD) and coronatine (COR) have been considered to be effective elicitors ...
