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 transcription factors CBF/DREB play an important role during low temperature, drought and high-salt stress in higher plants. In this work, we isolated one full-length CBF cDNA clone from the angiosperm Eucalyptus globulus. The derived peptide sequence reveals that it encodes a transcriptional activator that has all the characteristic motifs present in(More)

BACKGROUND During the last decade Revista Médica de Chile increased its visibility, measured on citations and impact factor. AIM To perform a scientometric analysis to assess the performance of Revista Médica de Chile. MATERIAL AND METHODS Thomson's-ISI Web of Science and Journal Citation Reports QCR) were consulted for performance indicators of Revista(More)
One full length (PrCESA10) and seven other cDNA clones (PrCESA2, 3, 5-8, 11) encoding cellulose synthases (CESAs) were isolated from the coniferous gymnosperm Pinus radiata. PrCESA10 encodes a protein predicted to contain the same domains and regions as angiosperm CESA genes: a zinc finger domain, a hypervariable region 1 (HVR1), a plant-conserved region(More)
Developing countries share disbelief about the benefits of the endogenous production of science as a tool for economical growth. Hence, public policies to strengthen science and technology and promote the culture of innovation are, in general, weak and sometimes incoherent. Patenting has become not only an icon to protect discoveries which can yield profits(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)
In January 2007, the Chilean Journal of Agricultural Research was indexed by the Institute of Scientific Information (ISI). This paper reviews the research that has been published since 2007 by using records extracted from the Web of Science database. The papers published were mostly affiliated to researchers from Chile, and six out of the ten(More)
The development of different forms of communication and transportation during the past century triggered a phenomenon known as globalization. One of the most striking and unexpected features of globalization has been the international exchange of students, whom have considered foreign universities as the following step towards their education. Since(More)
Environmental stress factors such as salt, drought and heat are known to affect plant productivity. However, high salinity is spreading throughout the world, currently affecting more than 45 millionha. One of the mechanisms that allow plants to withstand salt stress consists on vacuolar sequestration of Na(+), through a Na(+)/H(+) antiporter. We isolated a(More)
