Cooperativity in proton sensing by PIP aquaporins
(Wiley, 2019-03)One of the most intriguing properties of plasma membrane intrinsic protein (PIP) aquaporins (AQPs) is their ability to modulate water transport by sensing different levels of intracellular pH through the assembly of homo‐ ... -
Eco-physiological processes underlying maize water use efficiency response to plant density under contrasting water regimes
(Elsevier, 2020-09)This study quantified maize (Zea mays L.) water use efficiency for grain yield (WUEg) in response to plant density under contrasting water regimes; and focused on relevant eco-physiologial processes underlying the responses ... -
Effects of the source:sink ratio on the phenotypic plasticity of stem water potential in olive (Olea europaea L.)
(Society for Experimental Biology, 2011-06)The aims of this work were to quantify (i) the effect of the source:sink ratio on stem water potential (SWP) and (ii) the phenotypic plasticity of SWP and its relationship to oil yield components in olive. Trees with a ... -
Ensayo de fertilización líquida incorporada en trigo
(EEA Marcos Juárez, INTA, 2023-04-12)A inicios de la campaña de trigo 2022 se planificó un ensayo de evaluación de tratamientos de fertilización líquida con los productos Sol Mix ® (Bunge Argentina) y fertilizante biológico Nurture Soil ® (Biosoluciones SAS), ... -
Evaluación de cultivos de cobertura en la Unidad Demostrativa Agrícola de Bernardo de Irigoyen, Campaña 2016, departamento San Jerónimo (Santa Fe)
(EEA Oliveros, 2017)El objetivo de este trabajo fue evaluar la producción de biomasa y el consumo de agua de diferentes especies de cultivos de cobertura de crecimiento otoño-invernal, susceptibles de ser incluidas en las rotaciones agrícolas ... -
Genetic variability for leaf growth rate and duration under water deficit in sunflower: analysis of responses at cell, organ, and plant level
(Oxford Academic Press, 2008-05)Plants under water deficit reduce leaf growth, thereby reducing transpiration rate at the expense of reduced photosynthesis. The objective of this work was to analyse the response of leaf growth to water deficit in several ... -
Globe - LFMC a global plant water status database for vegetation ecophysiology and wildfire applications
(2019-08-21)Globe-LFMC is an extensive global database of live fuel moisture content (LFMC) measured from 1,383 sampling sites in 11 countries: Argentina, Australia, China, France, Italy, Senegal, Spain, South Africa, Tunisia, United ... -
High temperature during the budswell phase of grapevines increases shoot water transport capacity
(Elsevier, 2020-09)Knowledge about heat acclimation in perennial plants is limited. Our hypotheses were (i) that high temperature during budswell before budbreak elicits acclimation in grapevines that is mediated by greater water transport ... -
Influence of deficit irrigation and warming on plant water status during the late winter and spring in young olive trees
(Elsevier, 2023-01)Changes in rainfall patterns and increases in ambient air temperature (i.e., warming) are expected with climate change. Yet, little information is available on how plant water status will respond to the combination of water ... -
Phenotypic plasticity in leaf traits in response to experimental precipitation increase: wettability, foliar water uptake and gas exchange
(Wiley, 2023-07-12)Water availability is one of the factors affecting plant growth and development, especially in arid and semiarid environments. Changes in precipitation due climate change alter water availability to plants impacting on ... -
PIP aquaporin pH sensing is regulated by the length and charge of the C-terminal region
(Wiley, 2021-07)Plant PIP aquaporins play a central role in controlling plant water status. The current structural model for PIP pH-gating states that the main pH sensor is located in loopD and that all the mobile cytosolic elements ... -
A process-based numerical approach to estimate forest groundwater consumption in flatland petrocalcic soils
(International Water Association Publishing, 2019-11-01)Grasslands are extensively distributed in flatland areas around the world such as the Pampas in South-America. It is one of the most economically productive landscapes and, as in other regions, they are being replaced by ... -
