Promoter DNA Hypermethylation and Gene Repression in Undifferentiated Arabidopsis Cells
Maintaining and acquiring the pluripotent cell state in plants is critical to tissue regeneration and vegetative multiplication. Histone-based epigenetic mechanisms are important for regulating this undifferentiated state. ...
L'herbari de l'Institut Biològic de Sarrià: descripció general i plecs més interessants, amb noves aportacions corològiques
L'Institut Biològic de Sarrià, situat al coŀlegi Sant Ignasi - Jesuïtes de Sarrià de Barcelona, estigué actiu entre 1931 i 1965, i fou conegut arreu de l'estat espanyol i Europa pels seus estudis pioners en embriologia. ...
Emerging Agents for the treatment of Chagas disease: what is in the preclinical and clinical development pipeline?
ntroduction: Chagas disease treatment relies on the lengthy administration of benznidazole and/or nifurtimox, which have frequent toxicity associated. The disease, caused by the parasite Trypanosoma cruzi, is mostly diagnosed ...

Perfluorodecalin-supported system enhances taxane production in hairy root cultures of Taxus x media var. Hicksii carrying a taxadiene synthase transgene
Enhanced taxane production was observed in a hybrid, two liquid phases containing, cultures of Taxus x media var. Hicksii hairy root carrying a taxadiene synthase transgene, supported with liquid perfluorodecalin (PFD) in ...
L'eina "Taller" a Moodle: una experiencia d'autoavaluació i coavaluació en grups grans
El taller és una activitat integral i sistèmica que permet tant l'autoavaluació com l'avaluació per parells amb una flexibilitat molt àmplia per al professorat. Hi ha dues qualificacions per a un alumne: una per a la ...
Polyamines in Plant Biotechnology, Food Nutrition, and Human Health
Polyamines are small polycations derived from arginine and/or ornithine. These compounds are present in all living organisms and play common and organism-specific functions. Polyamines are present in most food products of ...
Alkaloid profile in Pyrolirion albicans Herb. (Amaryllidaceae), a Peruvian endemic species
The Amaryllidaceae family is widely distributed in different regions of the neotropics and temperate areas of the world. Species of the subfamily Amaryllidoideae are unique in producing the alkaloid galanthamine, which ...
Temporal origins and diversification of Artemisia and allies (Anthemideae, Asteraceae)
Temporal origins and diversification of Artemisia and allies (Anthemideae, Asteraceae).- To assess temporal origins and diversification of lineages within subtribe Artemisiinae and Artemisia group a penalized likelihood ...
A tau class glutathione-S-transferase is involved in trans-resveratrol transport out of grapevine cells
Vitis vinifera cell cultures respond to pathogens and elicitors by synthesizing and extracellularly accumulating stilbenoid phytoalexins. Large amounts of trans-resveratrol (t-R) are produced when a cell culture is elicited ...
Seasonal dynamics of canine antibody response to Phlebotomus perniciosus saliva in an endemic area of Leishmania infantum
Background: Canine leishmaniosis (CanL) is an important zoonotic parasitic disease, endemic in the Mediterranean basin. In this region, transmission of Leishmania infantum, the etiological agent of CanL, is through the ...
Ácaros parásitos de micromamíferos en Cataluña. III. Familia Myocoptidae
<p>The analysis of 20 small mammals species has allowed the discovery of 9 mite species belonging to the Myocoptidae family: Criniscansor apodemi, Myocoptes j. japonensis, M. musculinus, M. squamosus, Trichoecius apodemi, ...
Polyamine Oxidase 5 loss-of-function mutations in Arabidopsis thaliana trigger metabolic and transcriptional reprogramming and promote salt stress tolerance.
The family of polyamine oxidases (PAO) in Arabidopsis (AtPAO1-5) mediates polyamine (PA) back-conversion, which reverses the PA biosynthetic pathway from spermine, and its structural isomer thermospermine (tSpm), into ...
Prediction of whole-genome DNA G+C content within the genus Aeromonas based on housekeeping gene sequences
Different methods are available to determine the G+C content (e.g. thermal denaturation temperature or high performance liquid chromatography, HPLC), but obtained values may differ significantly between strains, as well ...
Repeated reunions and splits feature the highly dynamic evolution of 5S and 35S ribosomal RNA genes (rDNA) in the Asteraceae family
Background In flowering plants and animals the most common ribosomal RNA genes (rDNA) organisation is that in which 35S (encoding 18S-5.8S-26S rRNA) and 5S genes are physically separated occupying different chromosomal ...
Metabolic gene expression and centelloside production in elicited Centella asiatica hairy root cultures
The most economically important centellosides, madecassoside and asiaticoside, are produced in very low amounts in Centella asiatica (L.) Urban roots. With the aim of overcoming this limitation, in this work we compared ...
