Summary: The elevated CO2 concentration (eCO(2)) has the potential to improve plant water relations and carbon uptake, mitigating the effects of drought stress. However, the interactive effects of eCO(2) and drought on plant physiology and growth are not well understood. A meta-analysis was performed to investigate the interactive effects of eCO(2) and drought on plant water relations, photosynthesis, biomass production, and allocation. The results suggest that eCO(2) can improve leaf water status under drought conditions by reducing stomatal conductance and increasing root to shoot ratio. Elevated CO2 also alleviates the stomatal limitations on photosynthesis, leading to a stronger response to eCO(2) under drought conditions. However, eCO(2) and drought do not interact significantly on plant biomass production. The findings highlight the importance of eCO(2) in mitigating the adverse effects of drought on plant water relations and carbon sequestration.

Summary: Elevated CO2 concentration can alleviate the limitation of stomatal morphology traits on stomatal conductance regulation and increase dependency on leaf nitrogen concentration for photosynthetic performance in wheat species under different water regimes. Modern cultivated cultivars exhibit higher photosynthetic performance per unit of leaf nitrogen compared to wild species, indicating potential opportunities for breeding cultivars with better photosynthetic nitrogen use efficiency in future CO2 rising climates.

Summary: Green light partially replacing red light and blue light improves drought tolerance in cucumber seedlings by promoting the synthesis of GABA and upregulating the expression of the CsGAD2 gene. This study highlights the role of green light in plant physiological processes and suggests that analyzing the function of green light in improving drought tolerance could lead to new approaches for enhancing plant stress resilience.

Summary: Contrasting leaf anatomy of walnut species can provide insights into the links between structure and function. The experiment with two walnut species under stressed and drought conditions showed that leaf structure affects gas exchange, light absorption, and photosynthetic capacity, and drought-induced changes in leaf structure impact performance.

Summary: This study investigated the effects of potassium deficiency on water use efficiency, leaf water status, osmotic adjustment, gas exchange traits, and stomatal characteristics of rice under water deficit conditions. The results indicated that potassium deficiency limited the water deficit tolerance of rice by reducing relative water content and water potential of the leaves, leading to decreased water use efficiency and grain yield.

Summary: The study showed that both film antitranspirants and metabolic antitranspirants can increase grain yield under drought conditions, with a more pronounced effect observed in controlled drought scenarios. Leaf ABA concentration was negatively correlated with yield, but multiple applications of exogenous ABA could lead to higher yields.

Summary: Under future climate change with elevated CO2 concentration and more frequent drought events, the positive acclimation responses of Chinese pear plantations to elevated [CO2] in terms of leaf photosynthesis are dampened by modifying stomatal morphology and distribution, leaf anatomy, and Rubisco gene expression. Therefore, incorporating drought limitations into current coupled climate-carbon models is necessary to avoid overestimation of the positive responses of Chinese pear plantations to elevated [CO2] and to accurately predict forest carbon sequestration.

Summary: Rolled leaf (RL) is a morphological strategy to protect plants from dehydration under stressed field conditions. Quantitative trait loci (QTLs) for RL were identified on chromosomes 1A (QRl.hwwg-1AS) and 5A (QRl.hwwg-5AL), explaining up to 56% and 20% of the phenotypic variation, respectively. The analysis of recombinants delimited QRl.hwwg-1AS to a 6.04 Mb physical interval, providing the foundation for finer mapping and map-based cloning of QRl.hwwg-1AS.

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: This study utilized ecological niche models to explore the relationship between potential habitat suitability and productivity of Populus deltoides on a global scale. The results showed a significant positive correlation between habitat suitability and productivity, with key abiotic factors such as annual mean temperature, mean temperature of the coldest quarter, and topsoil gravel content influencing habitat suitability and stand productivity. Additionally, climate change scenarios projected a potential loss in global total productivity of P. deltoides, leading to recommendations for adaptive management strategies based on the predicted changes in productivity.

Summary: Satellite-based land cover products are essential for sustainability, with different types of products exhibiting varying levels of uncertainty in their accuracy. This study in China utilized multiple land cover datasets to analyze spatial and temporal changes in forest and nontree vegetation, finding overall low uncertainty but significant differences in local areas. As spatial resolution decreases, so does uncertainty, with a resolution of 0.1 degrees being a turning point in consistency.

Summary: Soil moisture is crucial for the energy exchange and transformation between the atmosphere, vegetation, and soil. Reliable estimation of root zone soil moisture at the regional scale is important for various applications. Currently, satellite products only provide surface soil moisture, making it challenging to obtain regional-scale root zone soil moisture. The soil moisture analytical relationship (SMAR) model based on a simplified soil water balance equation shows promise in linking surface and root zone soil moisture.
