Summary: Monitoring plant transpiration is crucial for optimizing irrigation and soil moisture conditions. A new method using continuous measurement of stem water potential dynamics was proposed to monitor plant water use. The study found that daytime root to stem hydraulic conductance remained stable and the effects of plant capacitance were negligible, indicating that plant transpiration dynamics can be inferred from stem water potential. Optical dendrometers showed potential in continuously monitoring transpiration and plant hydration status with high accuracy and temporal resolution under varying atmospheric conditions and optimum water supply. This method could be beneficial for improving crop productivity by maintaining optimal plant hydration levels.

Summary: Plant canopies being wet for extended periods affects physiological performance and ecosystem energy, carbon, and water fluxes. Leaf wetness sensors can quantify wetness duration and map it spatially to canopy structure. Manual analysis of data from plot-level experiments may be time-consuming and subjective, leading to inconsistencies.

Summary: Plant responses to water stress affect water and carbon cycles and may have climate feedbacks, but characterizing these responses at the ecosystem level is uncertain. Quantifying ecosystem-level water use strategies is challenging due to difficulties in upscaling plant traits and disentangling environmental factors, limiting our understanding of global change in ecosystem dynamics and ecohydrological fluxes.

Summary: Maintenance of optimal leaf tissue humidity is vital for plant productivity and food security. The regulation of water and solute flux across plant cell membranes, influenced by aquaporin proteins, is crucial for achieving this optimal humidity. However, understanding the dynamics of aquaporin regulation and their influence on leaf cell solute flux and humidity remains challenging.

Summary: Plants are capable of absorbing water through their leaf surfaces, with stomata playing a crucial role in foliar water uptake. Stomata closure significantly affects the rehydration rate of leaves, emphasizing the importance of stomatal pathways for efficient water absorption in plants. Further research is needed to understand the underlying mechanisms and implications of foliar water uptake for plant productivity and survival.

Summary: This study investigated 19 hydraulic traits in 40 woody species in a tropical savanna, finding significant variation in plant hydraulic traits based on leaf habit. Semi-deciduous species and shrubs showed the highest branch dieback and top-kill during drought, suggesting an important correlation between hydraulic traits and plant response to extreme dry conditions. Combining hydraulic traits with leaf habit and growth form led to better predictions of dieback and top-kill, indicating the potential for integrating life history traits with hydraulic traits for improved understanding and prediction of plant responses to drought.

Summary: Soil water deficit and saline-alkaline stress pose challenges to agriculture, and the effects of plant salt tolerance on soil water budget and root zone salinization and alkalization trends have not been fully understood. This study introduces a species-dependent soil water and salinity model that simulates the feedback between evapotranspiration and salinity in irrigated agroecosystems. Results show that plant salt tolerance plays a dominant role in regulating vegetation feedback and root zone salinity levels. It is important to consider plant salt tolerance for agricultural sustainability and environmental protection measures.

Summary: The study found that certain hydraulic fracturing additives from FPW can be absorbed by wheat, affecting plant growth and yield. However, in real-world scenarios, uptake may be reduced due to natural degradation, treatment, and dilution of water. Despite this, due to existing data gaps, chemical-specific treatments and regulatory safeguards are still recommended.

Summary: This study investigated the drought response of two sugarcane cultivars and found that 'IACSP94-2094' exhibited better water use efficiency and carboxylation efficiency compared to 'IACSP97-7065'. RNA-seq analysis revealed differentially expressed genes related to photosynthesis, transcription factors, signal transduction, solute transport, and redox homeostasis. The drought-tolerant genotype also showed a robust antioxidant system. These findings provide valuable insights for sugarcane breeding programs and understanding the genetic basis of drought tolerance and water use efficiency improvement.

Summary: Drip irrigation has been widely implemented in arid agricultural regions to mitigate water shortage and improve water productivity. It was found that drip irrigation increased yield and water productivity, while decreasing leaf area index. The promotion of root development and increase in soil temperature were key factors contributing to the improved crop activity.

Summary: This study investigates the water relations of epiphytic plants under drought and dry atmospheric conditions, and evaluates the plasticity of functional leaf traits under drought conditions. The results show that epiphytes exposed to drought and dry atmospheric conditions have significantly reduced stomatal conductance and leaf water potential, and an increase in leaf dry matter. Projected increases in cloud base height will reduce the growth and performance of epiphytic communities, and nonsucculent epiphytes may be particularly vulnerable.

Summary: This study investigated epiphyte communities in a tropical montane cloud forest region in Costa Rica and found differences in functional traits among different sites. However, there was still overlap in functional trait space across multiple sites. Significant correlations were found among functional traits in the epiphyte community, with leaf succulence emerging as an important trait.

Summary: Evolutionary relationships play a significant role in shaping plant physiological and structural traits. The study reviews research on phylogenetic signal and correlated evolution in plant-water relation traits. It found stronger phylogenetic signal in structural traits and correlated evolution among traits related to water movement efficiency and hydraulic safety. Considering evolutionary relationships could enhance our understanding of traits comparison, coordination, and variation with the environment.

Summary: The timing and magnitude of grassland responses to drought within a growing season remain unresolved. This study used remote sensing data and weather data to investigate the impacts of drought on grasslands in the western US Great Plains biome. The results showed that grassland carbon uptake was reduced during drought, with larger reductions in the warmer and more southern regions. Increased summer vapor pressure deficit was strongly linked to reductions in vegetation greenness during drought.
