25 p, 880.9 KB Drought tolerance induced by sound in Arabidopsis plants / López Ribera, Ignacio (Centre de Recerca en Agrigenòmica) ; Vicient Sánchez, Carlos M. (Centre de Recerca en Agrigenòmica)
We examined the responses of sound-treated arabidopsis adult plants to water deprivation and the associated changes on gene expression. The survival of drought-induced plants was significantly higher in the sound treated plants (24,8%) compared with plants kept in silence (13,3%). [...]

41 p, 1.6 MB Sequence of plant responses to droughts of different timescales : lessons from holm oak (Quercus ilex) forests / Barbeta i Margarit, Adrià (Centre de Recerca Ecològica i Aplicacions Forestals) ; Peñuelas, Josep (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
The functional traits of plants in regions of the world with a Mediterranean climate have been shaped to tolerate periods of water deficit. These species are adapted to summer droughts but may not be able to cope with future increases in drought intensity, duration, and/or frequency. [...]

10 p, 481.9 KB Effective use of water and increased dry matter partitioned to grain contribute to yield of common bean improved for drought resistance / Polania, José A. (Universitat Autònoma de Barcelona. Laboratori de Fisiologia Vegetal) ; Poschenrieder, Charlotte (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Beebe, Stephen (Centro Internacional de Agricultura Tropical) ; Rao, Idupulapati M. (Centro Internacional de Agricultura Tropical)
Common bean (Phaseolus vulgaris L. ) is the most important food legume in the diet of poor people in the tropics. Drought causes severe yield loss in this crop. Identification of traits associated with drought resistance contributes to improving the process of generating bean genotypes adapted to these conditions. [...]

60 p, 4.7 MB Coupling a water balance model with forest inventory data to predict drought stress : the role of forest structural changes vs. climate changes / Càceres, Miquel de (Centre de Recerca Ecològica i Aplicacions Forestals) ; Martínez Vilalta, Jordi, 1975- (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Coll, Lluís (Centre Tecnològic Forestal de Catalunya) ; Llorens García, Pilar (Institut de Diagnosi Ambiental i Estudis de l'Aigua) ; Casals, Pere (Centre Tecnològic Forestal de Catalunya) ; Poyatos López, Rafael (Centre de Recerca Ecològica i Aplicacions Forestals) ; Pausas, Juli G. (Centro de Investigaciones sobre Desertificación) ; Brotons Alabau, Lluís (Centre de Recerca Ecològica i Aplicacions Forestals)
Mechanistic water balance models can be used to predict soil moisture dynamics and drought stress in individual forest stands. Predicting current and future levels of plant drought stress is important not only at the local scale, but also at larger, landscape to regional, scales, because these are the management scales at which adaptation and mitigation strategies are implemented.

36 p, 1.2 MB A new look at water transport regulation in plants / Martínez Vilalta, Jordi, 1975- (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Retana Alumbreros, Javier (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Poyatos López, Rafael (Centre de Recerca Ecològica i Aplicacions Forestals) ; Aguadé Vidal, David (Centre de Recerca Ecològica i Aplicacions Forestals) ; Mencuccini, Maurizio (University of Edinburgh. School ofGeoSciences)
Plant function requires effective mechanisms to regulate water transport at a variety of scales. Here, we develop a new theoretical framework describing plant responses to drying soil, based on the relationship between midday and predawn leaf water potentials. [...]

66 p, 2.7 MB Factors influencing the foliar elemental composition and stoichiometry in forest trees in Spain / Sardans i Galobart, Jordi (Centre de Recerca Ecològica i Aplicacions Forestals) ; Alonso, Rocío (Centro de Investigaciones Energéticas, Medioambientales y Tecnológicas (Espanya)) ; Carnicer i Cols, Jofre (Universitat de Barcelona. Departament d'Ecologia) ; Fernández Martínez, Marcos (Centre de Recerca Ecològica i Aplicacions Forestals) ; García Vivanco, Marta (Centro de Investigaciones Energéticas, Medioambientales y Tecnológicas (Espanya)) ; Peñuelas, Josep (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
Concentrations of nutrient elements in organisms and in the abiotic environment are key factors influencing ecosystem structure and function. We studied how concentrations and stoichiometries of nitrogen (N), phosphorus (P) and potassium (K) in leaves of forest trees are related to phylogeny and to environmental factors (mean annual precipitation, mean annual temperature, forest type, and nitrogen deposition).

Water availability is the most limiting factor to global plant productivity, yet photosynthetic responses to seasonal drought cycles are poorly understood, with conflicting reports on which limiting process is the most important during drought. [...]

(Universidad San Pablo CEU. Unidad de Biologia Vegetal) ; Pozuelo González, J. M. (Universidad San Pablo CEU. Unidad de Biologia Vegetal) ; Lucas García, José Antonio (Universidad San Pablo CEU. Unidad de Biologia Vegetal) ; Probanza Lobo, Agustín (Universidad San Pablo CEU. Unidad de Biologia Vegetal)
European alder (Alnus glutinosa [L. ] Gaertn) nodules were maintained under conditions that allow their exudation (water stress). The effect of this nodular extracts colected on free nitrogen fixation (acetylene reduction assay [ARA]) and denitrification, was evaluated in three soils of significativelydifferent physico-chemicalcharacteristics. [...]

29 p, 95.2 KB Arquitectura hidràulica, vulnerabilitat a l'embolisme i resistència a la sequera en plantes llenyoses / Martínez Vilalta, Jordi, 1975- (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Piñol i Pascual, Josep (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
Els darrers anys han canviat algunes de les idees referents a les relacions hídriques de les plantes. D'una banda, s'ha posat més èmfasi en l'estudi del transport d'aigua a l'interior del xilema i, de l'altra, s'ha reconegut l'existència de limitacions biofísiques relacionades amb l'arquitectura d'aquesta via. [...]
Last years, some ideas concerning plant water relations have changed. On one hand, more emphasis has been put in the study of water transport inside the xylem and, on the other, biophysical limitations related to the architecture of this pathway have been recognized. [...]
