Summary: The study demonstrated that spraying arginine improved sugarcane plants' tolerance to water deficit by enhancing leaf gas exchange and root antioxidative protection. While arginine prevented proline accumulation induced by water deficit, its effects on nitric oxide and polyamines levels were slight.

Summary: Understory plants in deciduous forests rely on phenological escape in spring for assimilating carbon, which significantly affects their survival. Fall phenological escape plays a minor role in seedling demographic performance. Foliar desiccation is a key factor driving seedling survival, indicating that water availability shapes recruitment dynamics.

Summary: The main objective of this study was to develop a method to identify and characterize drought-tolerant potato genotypes and the related key traits. Potato genotypes differed in their ability to tolerate drought based on their capacity to maintain percent tuber yield under drought relative to their well-watered controls. The rates of photosynthesis, instantaneous water-use efficiency (WUE), and leaf protein content can be used as the selection criteria for drought-tolerant potato genotypes.

Summary: The encapsulation of NO donors, specifically SNAC, GSNO, and SNP, showed varying effects on sugarcane plants under water deficit conditions. SNAC spraying partially attenuated the negative impact of water deficit, while GSNO and SNAC spraying improved sugarcane photosynthesis during the recovery period. However, SNP spraying was not effective in mitigating water deficit effects on sugarcane plants. Overall, leaf spraying with SNAC or GSNO is an alternative to improve the physiological performance of sugarcane plants after water deficit, leading to a rapid recovery of photosynthesis and potentially increased crop yield.

Summary: Drought has a significant impact on crop growth, and understanding the short-term and long-term responses of crops to drought is crucial. Field data analysis showed that different water supply treatments strongly influenced leaf and canopy gas exchange, as well as cumulative growth in winter wheat and maize. The long-term morphological responses of winter wheat played a larger role in regulating transpiration and assimilation rates, while maize exhibited physiological advantages and morphological adjustments under drought conditions. Improved modeling of gas exchange and crop growth should consider dynamic changes in leaf area and stomatal regulation.

Summary: This study investigated the relative importance of water and carbon factors in fruit growth under drought conditions, finding that photosynthesis played a crucial role during intense cell division, while turgor was more important when cell division slowed down and growth depended on cell expansion. Despite differences in water deficit levels, turgor was identified as the major limitation to fruit growth, supporting the sink limitation hypothesis.

Summary: The aim of this study was to understand the morpho-physiological basis of biomass production by energy cane. Results showed that energy cane with high tillering had higher light interception efficiency, but excessive tiller density may lead to self-shading and reduced photosynthetic activity. However, energy cane was less sensitive to water stress compared to sugarcane in terms of light conversion efficiency and biomass yield.

Summary: This study investigated the molecular mechanism of sugarcane's response to drought stress (DS) and the potential alleviating effects of chitooligosaccharide (COS). Transcriptome and metabolome analyses were performed on sugarcane under three different treatment groups. The results revealed that DS significantly affected the photosynthesis of sugarcane and COS treatment could alleviate these negative effects. Metabolome analysis identified specific metabolites related to DS, and COS treatment reduced their content. Overall, this study provides valuable insights into the physiological and molecular responses of sugarcane to DS and demonstrates the potential of COS as a protective agent.

Summary: The study compared the responses of two potential genotypes and two commercial cultivars to drought and water recovery, and determined the drought tolerance strategies of the new genotypes by measuring root anatomy and photosynthetic parameters. The results showed that the new genotypes enhanced drought tolerance by increasing root hair number and adjusting root structure. Despite the reduction of photosynthetic parameters under drought conditions, the genotypes showed higher photosynthetic efficiency after water recovery.

Summary: Drought is a major abiotic stress that limits crop growth and yield worldwide. Mineral nutrients, such as boron (B), have shown promise in increasing plant tolerance to abiotic stresses. This study aimed to evaluate the benefits of foliar application of B in relieving water stress-induced physiological damages in soybean. Results showed that foliar supplementation with B increased antioxidant enzyme activities and reduced stress marker levels, resulting in improved plant growth and higher yield. Overall, foliar application of B proved to be an alternative management strategy for mitigating drought stress in soybean.

Summary: Water deficit inhibits plant growth and leads to overproduction of reactive oxygen species (ROS), causing oxidative stress. Iodine (I) has been shown to enhance the antioxidant defense system and improve photosynthesis under adverse conditions. In this study, soybean plants exposed to potassium iodide (KI) concentrations of 10 and 20 .mol L-1 showed increased biomass, improved gas exchange, and reduced lipid peroxidation under water deficit. However, higher KI concentrations negatively affected photosynthetic efficiency, biomass accumulation, and partition under well-irrigated conditions.

Summary: This study evaluated the effectiveness of potassium iodide (KI) in mitigating water deficits and improving fruit quality in tomatoes. The results showed that a concentration of 100 μM of KI increased the yield of tomatoes under a water deficit condition, and also improved antioxidant activity and photosynthetic efficiency, while reducing malondialdehyde levels. Additionally, this concentration of KI promoted better fruit quality through increased antioxidant capacity and a decline in the maturation index.

Summary: Salinity is a major abiotic stress that affects the productivity of crops, particularly rice. This study evaluated the sensitivity and tolerance of upland rice lines to salinity. The results showed that salinity levels significantly influenced emergence and survival rates, while grain weight per plant was a reliable indicator of tolerance to salinity. Lines L6, L7, and L8 exhibited outstanding performance with minimal decreases in grain weight under increased NaCl treatments.
