Foliar water uptake in arid ecosystems: seasonal variability and ecophysiological consequences
Rooting depth Cell wall elasticity Leaf water potential Transpiration Rain pulse Dew formation
2024/1/12
Foliar water uptake (FWU) has been reported for different species across several ecosystems types. However, little attention has been given to arid ecosystems, where FWU during dew formation or small ...
Root architecture and hydraulics converge for acclimation to changing water availability
hydraulics roots achieve water availability root hydraulic architecture
2024/1/12
Because of intense transpiration and growth, the needs of plants for water can be immense. Yet water in the soil is most often heterogeneous if not scarce due to more and more frequent and intense dro...
Developmental plasticity in Arabidopsis thaliana under combined cold and water deficit stresses during flowering stage
Acclimation Bolting Cold Flower size Terminal combined stress Water deficit
2023/12/11
In nature, plants are exposed to multiple and simultaneous abiotic stresses that influence their growth, development, and reproduction. In the last years, the study of combined stresses has aroused th...
Ethylene enhances root water transport and aquaporin expression in trembling aspen (Populus tremuloides) exposed to root hypoxia
chromosome engineering aquaporin ethylene flooding oxygen hydraulic conductance
2023/12/7
In this study, we examined the effects of root hypoxia and exogenous ethylene treatments on leaf gas exchange, root hydraulic conductance, and the expression levels of several aquaporins of the plasma...
Higher leaf nitrogen content is linked to tighter stomatal regulation of transpiration and more efficient water use across dryland trees
arid ecosystems ci/ca ratio leafδ13C leaf δ18O plant isotopic composition
2023/11/28
The least-cost economic theory of photosynthesis shows that water and nitrogen are mutually substitutable resources to achieve a given carbon gain. However, vegetation in the Sahel has to cope with th...
Amplifying effects of recurrent drought on the dynamics of tree growth and water use in a subalpine forest
dehydration dynamics drought legacy effects stem capacitance
2023/11/28
Despite recent advances in our understanding of drought impacts on tree functioning, we lack knowledge about the dynamic responses of mature trees to recurrent drought stress. At a subalpine forest si...
Leaf water potential measurements using the pressure chamber: synthetic testing of assumptions towards best practices for precision and accuracy
leaf water potential plant water relations plant water status pressure bomb pressure chamber water stress
2023/11/28
Leaf water potential (ψ leaf), typically measured using the pressure chamber, is the most important metric of plant water status, providing high theoretical value and information content for multiple ...
Convergence in water use efficiency within plant functional types across contrasting climates
water use efficiency plant functional types climates grassland permanent wetland savannah deciduous broadleaf and deciduous needleleaf forest
2023/11/28
Water use efficiency (WUE) provides a direct measure of the inextricable link between plant carbon uptake and water loss, and it can be used to study how ecosystem function varies with climate. We ana...
Arbuscular mycorrhizal fungi induce flavonoid synthesis for mitigating oxidative damage of trifoliate orange under water stress
antioxidants flavonoids mycorrhiza reactive oxygen species water stres
2023/11/16
Arbuscular mycorrhizal (AM) fungi can increase the tolerance of host plants to drought, whereas the intrinsic mechanisms are not still fully elucidated. Flavonoids are a kind of antioxidants to scaven...
The effect of biochar amendment on the growth, morphology and physiology of Quercus castaneifolia seedlings under water-deficit stress
Biomass Chestnut-leaved oak Water deficit Photosynthesis Xylem water potential
2024/2/28
Water stress is one of the most important environmental stresses which can adversely affect soil fertility and plant growth in arid and semiarid regions. In this study, biochar was used as a type of s...
