A customizable method to characterize Arabidopsis thaliana transpiration under drought conditions
BMC (2019)Background: Characterization of the dynamic response of plant transpiration to decreasing soil water content in a reproducible way is required for the correct phenotyping of traits related to water saving strategies. ... -
El ácido jasmónico señaliza la respuesta de los cítricos a la sequía
Ediciones y Promociones LAV (2012)El estrés hídrico afecta a diferentes parámetros fisiológicos en cítricos además de reducir la producción y la calidad de los frutos. Las plantas responden a la sequía regulando el estado hídrico y aumentando la abscisión ... -
Depletion of abscisic acid levels in roots of flooded Carrizo citrange (Poncirus trifoliata L. Raf. x Citrus sinensis L. Osb.) plants is a stress-specific response associated to the differential expression of PYL/PYR/RCAR receptors
Springer Verlag (2017)Soil flooding reduces root abscisic acid (ABA) levels in citrus, conversely to what happens under drought. Despite this reduction, microarray analyses suggested the existence of a residual ABA signaling in roots of flooded ... -
Drought resistance in oat involves ABA-mediated modulation of transpiration and root hydraulic conductivity
Elsevier (2020-11-30)Drought is one of the most important constraints to crop productivity worldwide. Control of plant responses to drought is very complex. The mechanisms and their intensity may differ between species and/or genotypes ultimately ... -
Engineered drought-induced biosynthesis of α-tocopherol alleviates stress-induced leaf damage in tobacco
Elsevier (2013)Tocopherols are members of the vitamin E complex and essential antioxidant compounds synthesized in chloroplasts that protect photosynthetic membranes against oxidative damage triggered by most environmental stresses. ... -
Fatty Acid Profile Changes During Gradual Soil Water Depletion in Oats Suggests a Role for Jasmonates in Coping With Drought
Frontiers Media (2018-07-31)Although often investigated within the context of plant growth and development and/or seed composition, plant lipids have roles in responses to environment. To dissect changes in lipid and fatty acid ... -
Influence of Exogenous Glycine Betaine and Abscisic Acid on Papaya in Responses to Water-deficit Stress
Springer-Verlag (2012)The effects of exogenous foliar glycine betaine (GB) and abscisic acid (ABA) on papaya responses to water stress were investigated under distinct water regimes. Papaya seedlings (Carica papaya L. cultivar “BH-65”) were ... -
Involvement of the def-1 Mutation in the Response of Tomato Plants to Arbuscular Mycorrhizal Symbiosis Under Well-Watered and Drought Conditions
Oxford University Press (2018)Jasmonic acid (JA) and arbuscular mycorrhizal (AM) symbioses are known to protect plants against abiotic and biotic stresses, but are also involved in the regulation of root hydraulic conductance (L). The objective of ... -
Leaf dehydration is needed to induce abscisic acid accumulation in roots of citrus plants
Elsevier (2017-05-09)The root system is the main organ involved in the water uptake and it is assumed that it perceives soil dehydration, triggering water stress responses at the entire plant level, including abscisic acid (ABA) accumulation. ... -
Modulation of Antioxidant Defense System Is Associated with Combined Drought and Heat Stress Tolerance in Citrus
Frontiers Media (2017-06)Drought and high temperatures are two major abiotic stress factors that often occur simultaneously in nature, affecting negatively crop performance and yield. Moreover, these environmental challenges induce oxidative ... -
River basins and water management in Spain. Tagus and Ebro river basin districts : an account of their current situation and main problems - Study
Publications Office of the European Union (2017-01-11)This Study was commissioned and overseen by the European Parliament’s Policy Department for Citizens’ Rights and Constitutional Affairs at the request of the PETI committee. It aims to analyse issues related to the petitions ... -
Root ABA Accumulation in Long-Term Water-Stressed Plants is Sustained by Hormone Transport from Aerial Organs
Oxford University Press (2015)The reduced pool of the ABA precursors, b,b-carotenoids, in roots does not account for the substantial increase in ABA content in response to water stress (WS) conditions, suggesting that ABA could be transported from ... -
Water Stress Responses of Tomato Mutants Impaired in Hormone Biosynthesis Reveal Abscisic Acid, Jasmonic Acid and Salicylic Acid Interactions
Frontiers Media (2015)To investigate the putative crosstalk between JA and ABA in Solanum lycopersicum plants in response to drought, suppressor of prosystemin-mediated responses2 (spr2, JA-deficient) and flacca (flc, ABA-deficient) mutants ...
