Summary: The impacts of plastic particles, especially in agro-ecosystem, are being extensively studied. In a simulation experiment, elevated atmospheric CO2 concentration increased nanoplastics concentration in NPs-treated roots. Furthermore, elevated CO2 concentration decreased H2O2 concentrations in NPs-treated leaves and roots by intervening antioxidant enzymes. In NPs-treated plants, elevated CO2 concentration increased P-n, C-i, and carotenoid concentration, while decreased g(s) and T-r. These findings provide insights into the eco-physiological response of barley plants to NPs under future agricultural sustainability.

Summary: This study found a significant positive effect of eCO2 on the growth, yield, and water-use efficiency of Ethiopian barley cultivars, particularly on grain number and grain yield. While some landraces showed better actual values, released cultivars benefited more from higher levels of CO2 in relative terms. The superior cultivars identified in this study could be valuable genetic resources for future barley breeding under future climate conditions.

Summary: This study evaluated the grain yield of different sets of spring barley genotypes under two treatments (no treatment and fungicide treatment) using AMMI, GGE biplot, and stability analysis. The results showed that the environment was the main factor contributing to grain yield variation, followed by genotype X environment interaction and genotypic effects. Utilizing the stable yielding genotypes and representative environments identified in this study could assist in breeding for improved grain yield in spring barley genotypes.

Summary: Plants respond to drought by reprogramming gene expression with the help of the phytohormone abscisic acid (ABA). This study investigated the response of barley plants to drought at both the epigenome and transcriptome levels. It was found that specific genes involved in ABA signaling and related pathways were induced in response to drought, including two members of the PP2C family. Histone modifications, such as H3K9 acetylation, were also found to be more sensitive to drought compared to H3K4 trimethylation.

Summary: This study aimed to screen drought stress tolerance in Moroccan barley cultivars. Physiological and biochemical parameters were measured to evaluate the drought tolerance. The results showed that drought stress reduced relative water content, shoot dry weight, and chlorophyll content, but increased electrolyte leakage, hydrogen peroxide, malondialdehyde, water-soluble carbohydrates, soluble protein contents, as well as catalase and ascorbate peroxidase activities. 'Firdaws','Laanaceur', 'Massine', 'Taffa', and 'Oussama' exhibited higher levels of shoot dry weight, relative water content, catalase, and ascorbate peroxidase activities, indicating strong drought tolerance. On the other hand, 'Adrar', 'Amalou', 'Amira', and 'Tamellalt' showed higher values of malondialdehyde and hydrogen peroxide content, suggesting drought sensitivity.

Summary: Ocean warming and marine heatwaves caused by climate change are affecting coral reefs globally, leading to coral bleaching and death. However, the resistance and resilience of corals to warming vary across reef sites and species. To understand coral health changes and mechanisms of thermal tolerance, it is important to have baseline data on coral performance under non-stressed conditions.

Summary: Research has found that climate change since the late 19th Century is not only characterized by a long-term increasing trend in annual mean temperature, but also by changes in within-year weather patterns relevant to crop production. The climate patterns in the late 20th and early 21st Century are distinct from those in the early 20th Century, providing clear evidence of changes in the entire weather profile, rather than just warming. This study also shows that crop yield and biomass production are impacted differently by the changing climate, with herbage production being more resilient than cereal crops.

Summary: We discuss the recent horticultural, biochemical, and molecular strategies adopted to improve the response of temperate fruit crops to water stress, as well as the feasibility of cultivating fruit trees in dry areas and protection methods. We provide a detailed analysis of the main factors involved in planting fruit trees in dry areas, such as plant material selection, regulated deficit irrigation strategies, rainwater harvesting, and anti-water stress materials. Additionally, we review the molecular mechanisms associated with the contribution of the microbiome to improving plant responses to drought.

Summary: The plant-specific ssDNA-binding protein WHIRLY1 is located in both chloroplasts and the nucleus, serving as a retrograde signal transmitting stress signals from chloroplasts to the nucleus and triggering stress-related gene expression there. In this study, the overexpression of WHIRLY1 in barley delayed the onset of senescence in response to drought stress. WHIRLY1 also affected ABA-related gene expression and histone modifications, functioning as a hub in balancing stress-related and developmental pathways.

Summary: Understanding the response of sorghum to drought under high CO2 levels is important for future crop production. This study found that sorghum, a C-4 plant, showed increased rates of stomatal conductance under normal CO2 levels and well-watered conditions. However, when exposed to drought, its physiological parameters and photosynthetic efficiency decreased significantly. After re-watering, sorghum plants exhibited different recovery patterns under different CO2 levels, with those grown under elevated CO2 requiring less recovery time. Overall, this research highlights the resilience of sorghum and its potential as a suitable crop for future drought situations.

Summary: The growth of quinoa under saline conditions is not strictly linked to photosynthesis performance. Other specific traits, rather than photosynthesis, explain the growth performance better. Phenotyping for salinity stress tolerance in quinoa is important for selecting traits that contribute to overall salinity tolerance and understanding the response mechanisms at a whole plant level.

Summary: Drought is a major challenge in agriculture due to its negative impact on crop growth and yield, but inoculating pulses with rhizobium strains can improve drought tolerance. This study evaluated the ability of indigenous rhizobia strains from nearby crop fields to enhance drought tolerance in common bean plants. Three strains were found to be highly efficient under drought conditions, showing better infectiveness and effectiveness compared to reference strains and chemically fertilized plants. These results provide a basis for developing efficient common bean inoculants to increase crop yield under drought conditions in Northern Spain.
