2-DE proteomics analysis of drought treated seedlings of Quercus ilex supports a root active strategy for metabolic adaptation in response to water shortage
(Frontiers Media, 2015)Holm oak is a dominant tree in the western Mediterranean region. Despite being well adapted to dry hot climate, drought is the main cause of mortality post-transplanting in reforestation programs. An active response to ... -
Competition modulates the response of growth to climate in pure and mixed Abies pinsapo subsp. maroccana forests in northern Morocco
(Elsevier, 2020)The effects of changes in structure and composition on the dynamics and responses of secondary forests to climate change are understudied. Secondary forests of Abies pinsapo var. maroccana are often a mosaic of patches of ... -
Contrasting Response to Drought and Climate of Planted and Natural Pinus pinaster Aiton Forests in Southern Spain
(MDPI, 2019)Extreme drought events and increasing aridity are leading to forest decline and tree mortality, particularly in populations near the limits of the species distribution. Therefore, a better understanding of the growth ... -
Differences in the Response to Acute Drought and Phytophthora cinnamomi Rands Infection in Quercus ilex L. Seedlings
(MDPI, 2018)The sustainability of “dehesas” is threatened by the Holm oak decline. It is thought that the effects of root rot on plant physiology vary depending on external stress factors. Plant growth and biomass allocation are ... -
Droughts as a catalyst for water policy change. Analysis of Spain, Australia (MDB), and California
(Elsevier, 2019)Droughts are natural hazards characterized by a prolonged period of below-average precipitation. Water scarcity is defined as insufficient water resources to meet demands in a region. This paper examines three regions ... -
Integrating agronomic and genomic approaches for wheat adaptation to to Southern Spain Mediterranean agro-environments
(Universidad de Córdoba, UCOPress, 2019)Wheat (Triticum spp.) is one of the oldest domesticated crops and is of great importance as a staple food in the human diet. It shows an interesting phenotypic plasticity conferred by a large, polyploid and complex genome. ... -
Linkages between Climate, Radial Growth and Defoliation in Abies pinsapo Forests from Southern Spain
(MDPI, 2020)Systematic forest networks of health monitoring have been established to follow changes in tree vigor and mortality. These networks often lack long-term growth data, but they could be complemented with tree ring data, since ... -
Local inhibition of nitrogen fixation and nodule metabolism in drought-stressed soybean
(Oxford University Press, 2013)Drought stress is a major factor limiting symbiotic nitrogen fixation (NF) in soybean crop production. However, the regulatory mechanisms involved in this inhibition are still controversial. Soybean plants were symbiotically ... -
Mapping projected variations of temperature and precipitation due to climate change in Venezuela
(MDPI, 2023)The impacts of climate change will not be homogeneous in all countries or between regions within each country. Mapping projected changes in temperature and precipitation is crucial for formulating region-specific agricultural ... -
Promotion of pregnant merino Ewes’ Welfare with the introduction of a drought- and high-temperature-resistant cereal into their diet: analysis of tritordeum meadow
(MDPI, 2023)Tritordeum is a new cereal resistant to drought and high temperatures, and it is a very healthy crop. The aim of this study was to compare two different diets (tritordeum meadow vs. oat meadow) for grazing pregnant ewes ... -
Responses and Differences in Tolerance to Water Shortage under Climatic Dryness Conditions in Seedlings from Quercus spp. and Andalusian Q. ilex Populations
(MDPI, 2020)Analyzing differences in tolerance to drought in Quercus spp., and the characterization of these responses at the species and individual population level, are imperative for the selection of resilient elite genotypes in ... -
Studies of variability in the response of holm oak (Quercus ilex L.) to stresses associated with the decline syndrome: Drought and Phytophthora cinnamomi
(Universidad de Córdoba, UCOPress, 2021)Resilience to adverse environmental conditions (biotic and abiotic stresses) is one of the main objectives in forest tree breeding programs, and it should be a priority for Holm oak (Quercus ilex), considered the increasing ... -
Transcriptomic Response to Water Deficit Reveals a Crucial Role of Phosphate Acquisition in a Drought-Tolerant Common Bean Landrace
(MDPI, 2020)Drought is one of the most critical factors limiting legume crop productivity. Understanding the molecular mechanisms of drought tolerance in the common bean is required to improve the yields of this important crop under ... -
Untargeted MS-Based Metabolomics Analysis of the Responses to Drought Stress in Quercus ilex L. Leaf Seedlings and the Identification of Putative Compounds Related to Tolerance
(MDPI, 2022)The effect and responses to drought stress were analyzed in Quercus ilex L. seedlings using a nontargeted metabolomic approach, implementing the approaches of previous studies in which other -omics platforms, transcriptomics, ... -
Water Productivity under Drought Conditions Estimated Using SEEA-Water
(MDPI, 2016)This paper analyzes the impact of droughts on agricultural water productivity in the period 2004–2012 in the Guadalquivir River Basin using the System of Environmental-Economic Accounting for Water (SEEA-Water). Relevant ...
