Summary: The study evaluated the potential of biogenic silver nanoparticles (B-AgNPs) as an effective ozone protectant for wheat, showing promising results in enhancing ozone tolerance and improving yield attributes in wheat cultivars. Particularly, the 25 mg/L concentration of B-AgNPs demonstrated a more pronounced effect on yield attributes and lower accumulation in grains for both cultivars.

Summary: Ground-level ozone concentration is increasing in Asia, which poses a major threat to global wheat supply as wheat is highly sensitive to ozone. Comparing China, India, Europe, and North America, China has the highest estimated yield loss followed by India, Europe, and North America. The reduction in single grain weight contributes to yield loss in China, Europe, and North America, while the reduction in the number of grains contributes more in India. The difference in cultivars used among regions may explain the differential yield response. It is important to quantify ozone-induced yield loss for each region, taking into account the effects of seasonal ozone concentration changes, cultivars, and climate.

Summary: Ground-level ozone has a significant impact on plant growth, metabolism, and yield, with different cultivars of groundnut showing varying levels of sensitivity. This study found that enhanced ozone exposure led to reduced yield in all cultivars, with Dh-86 being the most sensitive and TAG-24 being the least sensitive to ozone.

Summary: The study showed that ambient ozone poses a threat to the yield and nutritional quality of chilli plants, with EDU treatment resulting in better growth and yield parameters. However, there was no significant difference in mineral contents between the plants treated with EDU and the control group.

Summary: The study evaluated the response of thermotolerant wheat cultivar to ambient ground level ozone and particulate matter air pollutants, with ethylene diurea as a stress mitigator. Plants exposed to ozone and particulate matter exhibited foliar injury and reduced economic yield, while the EDU-treated plants without particulate matter showed improved morphology and yield. The findings underscore the need for further research on the impact of air pollutants on thermotolerant cultivars of key crops.

Summary: The study found that ethylenediurea (EDU) can effectively increase rice yield by increasing leaf nitrogen allocation to photosynthesis and grain nitrogen accumulation. Additionally, EDU mainly increases rice yield by increasing individual grain weight rather than the number of panicles and grains, but its protective effect is limited under high O3 pollution.

Summary: Recent research on ground-level ozone effects on plants has shifted from concentration-based exposure to a more physiologically realistic approach based on ozone uptake. Testing the evidence for the benefits of the latter approach is crucial for ozone risk assessment. Variability in ozone sensitivity in wheat response functions, particularly between AOT40 and POD methods, highlights the importance of considering environmental variables in assessing ozone impact on crops.

Summary: This study investigated the proteomic response in apoplast and chloroplast pathways of wheat varieties under ethylenediurea (EDU) treatment to tropospheric ozone (O-3). The results show that EDU activates antioxidant defense mechanisms and regulates protein abundance to minimize ozone stress. Plants can develop O-3 tolerance by optimizing the apoplast ROS pool under EDU treatment.

Summary: By reviewing the interacting processes determining sink strength and yield potential in wheat, and visualizing them in a set of 'wiring diagrams', the main traits determining sink strength were identified and research gaps were highlighted for achieving gains in sink strength. In the pre-anthesis phase, grain number could be increased through enhanced spike growth and improved fruiting efficiency. In the post-anthesis phase, grain sink strength could be augmented through manipulation of grain size potential and improving spike vascular architecture. The wiring diagrams provide a potential workspace for yield improvement in wheat and other field crops.

Summary: The study investigated the diversity of the TaGRF3-2A gene in Russian bread wheat germplasm, identifying a specific allele (TaGRF3-2Ab) associated with earlier heading and better grain filling under certain conditions. This allele was found to be more frequent in Russian winter wheat cultivars, suggesting adaptation to the Chernozem region. The results will aid in utilizing TaGRF3-2A mutations for future agronomic studies and wheat improvement.

Summary: In this study, the interactive effects of ozone, temperature, and water supply on wheat yield and grain quality were assessed. It was found that ozone, warming, and drought all decreased grain yield and average grain mass but increased grain concentration of nutrients. The results highlight the importance of considering water availability when assessing the impact of ozone on global food production.
