Molecular mechanisms of ITS2 processing, a eukaryotic insertion between the 5.8S and LSU rRNA, remain largely elusive even in yeast. To delineate ITS2 structural and functional features which could be common to eukaryotes, we first produced phylo-genetically supported folding models in the vertebrate lineage, then tested them in deeper branchings and, more(More)

The seasonal adaptation of the teleost Cyprinus carpio to the cyclical changes of its habitat demands physiological compensatory responses. The process involves profound nucleolar adjustments and remarkable changes in rRNA synthesis, which affects ribosomal biosynthesis. In this context, we have demonstrated that the synthesis of several proteins involved(More)
The purpose of this study was to carry out a bibliometric analysis of the articles published in Chile during 1987-2006 that were categorized into the Plant Science discipline by ISI. The data was extracted from the Web of Science datábase, obtaining a total of 911 articles for analysis. Almost half of the articles were the outcome of an international(More)
Boron is a micronutrient that plays an important role in plant cell wall biosynthesis. Nevertheless, an excess of boron in the soil causes severe damage to the respiratory tissue of the plant. In Arabidopsis thaliana, the Atbor1 gene encodes a boron transporter that distributes this element throughout the plant. A cDNA sequence encoding a bor1 transporter(More)
Desertification is a phenomenon that affects vast territories worldwide usually caused by high soil salt concentrations , being salt and water stress one of the main problems that affect plant growth. Part of the strategy developed by the plant to face these stresses consists on the compartmentalization of cytoplasmic Na + within the vacuole, by a(More)
