A Novel Hydroxylation Step in the Taxane Biosynthetic Pathway: A New Approach to Paclitaxel Production by Synthetic Biology
Engineered plant cell lines have the potential to achieve enhanced metabolite production rates, providing a high-yielding source of compounds of interest. Improving the production of taxanes, pharmacologically valuable ...
Membrane interaction of a new synthetic antimicrobial lipopetide sp-85 with broad spectrum activity
Antimicrobial peptides offer a new class of therapeutic agents to which bacteria may not be able todevelop genetic resistance, since their main activity is in the lipid component of the bacterial cell mem-brane. We have ...
Mediterranean species of Caulerpa are polyploid with smaller genomes in the invasive ones
Caulerpa species are marine green algae, which often act as invasive species with rapid clonal proliferation when growing outside their native biogeographical borders. Despite many publications on the genetics and ecology ...

Inactivation of UDP-glucose sterol glucosyltransferases enhances Arabidopsis resistance to Botrytis cinerea
Free and glycosylated sterols are both structural components of the plasma membrane that regulate their biophysical properties and consequently different plasma membrane-associated processes such as plant adaptation to ...
First report of Filaria martis Gmelin, 1790 in the European mink, Mustela lutreola (Linnaeus, 1761)
The riparian European mink (Mustela lutreola), currently surviving in only three unconnected sites in Europe, is now listed as a critically endangered species according to the IUCN. Habitat loss and degradation, anthropic ...
Aspectos sobre la capacidad de regeneración de Cystoseira mediterranea Sauvegeau
[spa] Los discos basales de Cystoseira mediterranea, desprovistos del eje y de toda ramificación pueden llegar a regenerar la planta completa. El crecimiento de los rebrotes y su velocidad de regeneración dependen de la ...
Interés florístico y geobotánico de la Sierra de Alcubierre (Monegros, Aragón)
sum tini Molero, Sáez and Villar-, altered by the presence of certain thermophilous coastal species, and finicolous and residual in character, are found in a few exceptional enclaves. Finally, stress is laid on the need ...
First finding of Ityogonimus lorum and I. ocreatus co-infection in the Iberian mole, Talpa occidentalis
The Ityogonimus lorum-I. ocreatus co-infection is reported for the first time in the Iberian mole Talpa occidentalis in Asturias (NW Spain). Both Ityogonimus species are stenoxenous helminths of insectivores of the genus ...
