Assessing tree drought resistance and climate-growth relationships under different tree age classes in a pinus nigra arn. Ssp. salzmannii forest
The magnitude of drought impact in forest ecosystems depends on which group of trees are more severely affected; greater mortality of smaller trees can modulate the trajectories of succession, while the mortality of larger ... -
Carbohydrate and amino acid dynamics during grain growth in four temperate cereals under well-watered and water-limited regimes
Grain development in cereals depends on synthesis and remobilisation compounds such as water-soluble carbohydrates (WSCs), amino acids (AAs), minerals and environmental conditions during pre-and post-anthesis. This study ... -
Constrained trait variation by water availability modulates radial growth in evergreen and deciduous mediterranean oaks
Spatial and temporal variation in functional traits allows trees to adjust to shifting environmental conditions such as water stress. However, the change of traits, both mean and variances, along water availability gradients ... -
Drought-induced changes in wood density are not prevented by thinning in Scots pine stands
Density is an important wood mechanical property and an indicator of xylem architecture and hydraulic conductivity. It can be influenced by forest management and climate. We studied the impact of thinning and climate ... -
Effect of volatile and non-volatile metabolites from Leptosphaeria maculans on tomato calli under abiotic stresses
Drought and salinity can be serious problems for agricultural productivity in certain planet areas. Leptosphaeria maculans is the causative agent of the blackleg in crucifer plants. In this work, a novel methodology for ... -
Interactions between climate and nutrient cycles on forest response to global change: the role of mixed forests
Forest ecosystems are undergoing unprecedented changes in environmental conditions due to global change impacts. Modification of global biogeochemical cycles of carbon and nitrogen, and the subsequent climate change are ... -
Is N-feedback involved in the inhibition of nitrogen fixation in drought-stressed Medicago truncatula?
Drought stress is a major factor limiting nitrogen fixation (NF) in crop production. However, the regulatory mechanism involved and the origin of the inhibition, whether local or systemic, is still controversial and so far ... -
Local inhibition of nitrogen fixation and nodule metabolism in drought-stressed soybean
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 ... -
Long-term mannitol-induced osmotic stress leads to stomatal closure, carbohydrate accumulation and changes in leaf elasticity in Phaselous vulgaris leaves
The effect of long-term osmotic stress was investigated in leaves of two common bean lines, with contrasting tolerance: Flamingo (tolerant) and coco blanc (sensitive). Water relations, organic solute, ion accumulation ... -
Mechanisms involved in drought stress tolerance triggered by rhizobia strains in wheat
Rhizobium spp. is a well-known microbial plant biostimulant in non-legume crops, but little is known about the mechanisms by which rhizobia enhance crop productivity under drought stress. This work analyzed the mechanisms ... -
Physiological, hormonal and metabolic responses of two alfalfa cultivars with contrasting responses to drought
Alfalfa (Medicago sativa L.) is frequently constrained by environmental conditions such as drought. Within this context, it is crucial to identify the physiological and metabolic traits conferring a better performance under ... -
A proteomic approach reveals new actors of nodule response to drought in split-root grown pea plants
Drought is considered the more harmful abiotic stress resulting in crops yield loss. Legumes in symbiosis with rhizobia are able to fix atmospheric nitrogen. Biological nitrogen fixation (SNF) is a very sensitive process ... -
A proteomic view on the role of legume symbiotic interactions
Legume plants are key elements in sustainable agriculture and represent a significant source of plant-based protein for humans and animal feed worldwide. One specific feature of the family is the ability to establish ... -
Short-term exposure to high atmospheric vapor pressure deficit (Vpd) severely impacts durum wheat carbon and nitrogen metabolism in the absence of edaphic water stress
Low atmospheric relative humidity (RH) accompanied by elevated air temperature and decreased precipitation are environmental challenges that wheat production will face in future decades. These changes to the atmosphere are ... -
SilvAdapt.Net: a site-based network of adaptive forest management related to climate change in Spain
Adaptive forest management (AFM) is an urgent need because of the uncertainty regarding how changes in the climate will affect the structure, composition and function of forests during the next decades. Current research ... -
Tree-to-tree competition in mixed European beech-Scots pine forests has different impacts on growth and water-use efficiency depending on site condition.
Mixed conifer-hardwood forests can be more productive than pure forests and they are increasingly considered as ecosystems that could provide adaptation strategies in the face of global ...
