Exiguobacterium pavilionensis str. N139, a halotolerant, UV-B and metal resistant bacteria from a high-altitude Andean lake

2016

We report the genome sequence of Exiguobacterium pavilionensis str. N139, isolated from a high-altitude Andean lake. The 2,952,588-bp genome contains one chromosome and three megaplasmids. The genome analysis suggests the presence of enzymes that confer E. pavilionensis str. N139 the ability to grow under multiple environmental extreme conditions, including high concentrations of different metals and high ultraviolet B radiation. Moreover, the regulation of its tryptophan biosynthesis suggests that novel pathways remain to be discovered, and that these pathways might be fundamental in the amino acid metabolism of the microbial community from Laguna Negra, Argentina .

Growth and defense in deciduous trees and shrubs under UV-B

2005

Abstract Reflection by waxy or resinous surface structures and hairs, repair reactions of biomolecules and induction of different sheltering components provide the means of plant protection from harmful solar UV-B radiation. Secondary products, especially flavonoids and phenolic acids as defense components are also important in plant tolerance to UV-B, fulfilling the dual role as screens that reduce UV-B penetration in plant tissues, and as antioxidants protecting from damage by reactive oxidant species. Plants are sensitive to UV-B radiation, and this sensitivity can be even more clone-specific than species-specific. The results available in the literature for deciduous trees and shrubs in…

Analysis of involvement of the 3?-untranslated regions in regulating mRNA stability for vitellogenin, cyanoprotein ?, and cyanoprotein ? from the bea…

2002

The degradation of the 3'-untranslated regions (UTRs) of vitellogenin, cyanoprotein alpha, and cyanoprotein beta from the bean bug, Riptortus clavatus, was analyzed in vitro. The degradation pattern was similar for all three RNAs, with a high degradation rate in non-diapausing adult insects and no degradation in the fifth instar nymphs and in diapausing adults, and was not correlated with the expression levels of these three proteins. Proteins binding to the 3'-UTRs were detected in polysomal and cytosolic extracts. These factors, however, were present in all developmental stages. The abundance of the polysomal factor showed little variation, but the cytosolic factor was enriched in adult i…

From a Barrio Chino Urban Stigma to the Raval Cultural Brand: Urban Memory and Cultural Policies in the Renewal of Central Barcelona

2020

Barcelona, and especially, its historic center, has undergone a profound transformation from an industrial city to a global tourism and services center. Some authors insist on the destructive nature of the urban regeneration of the historic Barcelona district of Raval as a process of de-identification of the city center or as an intentional falsification of its identity to turn it into a tourist space. However, as we discuss in this article, urban branding and urban change projects should address not only the infrastructural issues of transformation, but also the development of new urban branding based on recreating a memory of the place. Thus, in the case of Raval, the urban and cultural …

Proyecto Quick Natura. Tecnologías móviles aplicadas a rutas botánicas urbanas

2017

[EN] The Quick Natura project aims to approach people of the city of Valencia to the green areas around them,in a fast and pleasant way. The initiative is based on the use of new technologies to connect the physicalwith the virtual world by placing QR codes (Quick Response code) on di erent plant species, located mainlyin gardens and parks to display information about each labelled species. Any user can scan the QR codelocated in labelled plants by using a smartphone or other mobile devices, enabling almost immediate accessto an information layer displayed in an enjoyable way, without using very technical language, facilitatinga quick understanding and assimilation by users. The method allo…
