Las algas del canal olimpico de piraguismo de aguas tranquilas (Barcelona)
Se ha estudiado la flora algal del Canal de Piragüismo de Aguas Tranquilas durante un año. Se han identificado 90 taxa (20 Cyanophyta, 25 Chlorophyta , 1 Charophyta, 9 Euglenophyta, 31Chrysophyta, 2 Cryptophyta y 2 ...
The reference strain Aeromonas hydrophicla CIP 57.50 should be reclassified as Aeromonas salmonicida CIP 57.50
The use of reference strains is a critical element for the quality control of different assays, from the development of molecular methods to the evaluation of antimicrobial activities. Most of the strains used in these ...
Identification of defensin-encoding genes of Picea glauca: characterization of PgD5, a conserved spruce defensin with strong antifungal activity
Background: Plant defensins represent a major innate immune protein superfamily that displays strong inhibitory effects on filamentous fungi. The total number of plant defensins in a conifer species is unknown since there ...
Biotic Elicitors in Adventitious and Hairy Root Cultures: A Review from 2010 to 2022
One of the aims of plant in vitro culture is to produce secondary plant metabolites using plant cells and organ cultures, such as cell suspensions, adventitious, and hairy roots (among others). In cases where the biosynthesis ...
Phytosterol metabolism in plant positive-strand RNA virus replication
The genome of most plant viruses consists of a single positive-strand of RNA (+ ssRNA). Successful replication of these viruses is fully dependent on the endomembrane system of the infected cells, which experiences a massive ...
Marinobacter maroccanus sp. nov., a moderately halophilic bacterium isolated from a saline soil.
During the taxonomic investigation of exopolymer producing halophilic bacteria, a rod shaped, motile, Gram-stain-negative, aerobic, halophilic bacterium, designated strain N4<sup>T</sup>, was isolated from a natural saline ...
Sobre la necesidad de un libro rojo «moderno» para China
Los llamados «libros rojos» se cuentan hoy en día entre las mejores y más ampliamente utilizadas herramientas para la identificación de plantas vasculares sometidas a una situación de riesgo, así como para la priorización ...

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 ...
Optimization of a liquid chromatography-tandem mass spectrometry method for the quantification of traces of taxanes in a Corylus avellana cell suspension medium
Since the recent discovery of taxol and other taxanes in Corylus avellana, this plant species has attracted interest as a potential new source of these compounds. However, its low taxane content in comparison with Taxus ...
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 ...

During the taxonomic investigation of cold-adapted bacteria from samples collected in theAntarctic area of the South Shetland Islands, one Gram-reaction-negative, psychrotolerant,aerobic bacterium, designated strain M1T, ...
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 ...
