Molecular genetics of cork formation

La peridermis és una estructura complexa que protegeix els òrgans vegetals madurs (secundaris) i les zones que han sofert ferides de la pèrdua d'aigua i dels patògens. Aquesta funció barrera és deguda al fel·lema o súber, un teixit format per cèl·lules suberificades. Tant el fel·lema com la suberina són crucials per la vida de les plantes terrestres, però pràcticament no es coneix res dels processos moleculars que regulen la seva formació, probablement degut a la manca de models adequats. En aquesta tesi s'han identificat i caracteritzat gens induïts al fel·lema mitjançant la combinació de dues plantes models. L'escorça d'alzina surera (Quercus suber) s'ha utilitzat per aïllar gens candidats de la formació del fel·lema i per investigar el comportament d'alguns d'aquests gens durant l'estació de creixement, mentre que la pela de la patata (Solanum tuberosum) s'ha utilitzat en estudis de genètica reversa per demostrar la funció d'alguns gens reguladors al fel·lema.

Modelling spectral reflectance of open cork oak woodland: a simulation analysis of the effects of vegetation structure and background

This study analyses the influence of vegetation structure (i.e. leaf area index and canopy cover) and seasonal background changes on moderate-resolution imaging spectrometer (MODIS)-simulated reflectance data in open woodland. Approximately monthly spectral reflectance and transmittance field measurements (May 2011 to October 2013) of cork oak tree leaves (Quercus suber) and of the herbaceous understorey were recorded in the region of Ribatejo, Portugal. The geometric-optical and radiative transfer (GORT) model was used to simulate MODIS response (red, near-infrared) and to calculate vegetation indices, investigating their response to changes in the structure of the overstorey vegetation and to seasonal changes in the understorey using scenarios corresponding to contrasting phenological status (dry season vs. wet season). The performance of normalized difference vegetation index (NDVI), soil-adjusted vegetation index (SAVI), and enhanced vegetation index (EVI) is discussed. Results showed that SAVI and EVI were very sensitive to the emergence of background vegetation in the wet season compared to NDVI and that shading effects lead to an opposing trend in the vegetation indices. The information provided by this research can be useful to improve our understanding of the temporal dynamic of vegetation, monitored by vegetation indices.

Kvinnors upplevelse av planerad hemförlossning i Skandinavien : Women´s experience of planned home birth in the Scandinavian countries

Background: In Sweden and Norway planned home birth is not included in the health care system. In Denmark women with expected low risk birth have the right to choose home birth. Registrations of home births in the Nordic countries are not completed and women’s experiences of planned home birth in Scandinavian context are not earlier described.Objective: The aim of this study was to describe women’s experiences of planned home birth in the Scandinavian countries.Design: Inductive content analysis. Fifty-three Scandinavian women who have experienced planned home birth have replied an open question in a questionnaire. Findings: In the analysis five categories and twelve subcategories emerged. The categories were, to feel secure, experiences of support, being in control, harmony and insecurity. The women felt secure and calm in their own homes. They felt being in control, secure, support and trust in the midwife, relatives and the own body. What worried the women most in presence of the delivery was that the midwife should not be present. Keywords: Home birth, experiences, women.
