Summary: Climate change poses a threat to food security, particularly for crops like wheat, maize, and rice. The impact of climate change on these crops varies by region, with colder areas potentially experiencing increased yields while equatorial countries may see decreased production. Water scarcity, amplified by climate change, is likely to reduce rice yields globally. Multiple climate models and bias correction techniques should be used for more accurate predictions. Adaptation measures, such as adjusting planting calendars and improving crop varieties, are recommended to mitigate the adverse effects of climate change.

Summary: Increases in cereal grain yields have led to an increase in straw accumulation, often burned in the field causing pollution, greenhouse gas emissions, erosion, loss of organic matter, and wildfires. Alternative solutions, such as feeding straw to ruminants, may offer a more sustainable approach to utilize straw resources.

Summary: Straw input is a beneficial approach that enhances soil fertility, crop yield, and promotes sustainable agriculture. However, excessive straw input leads to significant greenhouse gas emissions, contributing to climate change and global warming. This study highlights the importance of optimizing straw input and management practices to increase soil carbon and nitrogen content, improve crop yield and nitrogen use efficiency, and reduce greenhouse gas emissions.

Summary: Extrusion treatment can improve the pretreatment effect and increase the biogas production of lignocellulosic materials. In this experiment, wheat straw and digested wheat straw were selected to evaluate the effect of extrusion treatment on the biogas production. The results showed that extrusion treatment can significantly increase the biogas and methane yields, especially for digested wheat straw, suggesting that extrusion treatment is a feasible pretreatment method for the reuse of digested wheat straw for biogas production.

Summary: China is a major producer of wheat, maize, and rice, but the production of these crops results in significant greenhouse gas emissions. In this study, we utilized a comprehensive approach to quantify the emissions from land, energy, and water in the cereal production of China. The results showed that the total greenhouse gas emissions from wheat, maize, and rice crops reached 505.5 Tg CO(2)eq, with land and energy being the major contributors. Additionally, there was significant spatial heterogeneity in greenhouse gas emissions at the provincial level, attributed to variations in crop type, natural resources, and management practices. The adoption of green technologies and sustainable food trade practices could effectively reduce greenhouse gas emissions and promote carbon neutrality in agriculture.

Summary: Iron toxicity is a major constraint to rice production, with varying tolerance levels in rice germplasm. Future breeding programs should be based on well-characterized molecular markers for iron toxicity tolerance traits, and tailored screening methods should be developed for individual mechanisms. Understanding and breaking down the complex tolerance response into its components will be crucial for successfully identifying such markers.

Summary: Microalgae from wastewater treatments can serve as a source of nutrients for crops, particularly nitrogen. Wheat plants treated with microalgae biomass showed improved physiological performance, growth, and nutrient uptake compared to the control. However, their yields and nitrogen use efficiency were lower than with mineral fertilizer, and the abundance of rhizosphere microbes and ammonia-oxidizing microorganisms were not significantly affected.

Summary: The rice root system consists of two types of lateral roots, L-type and S-type, which both contribute to nutrient and water uptake. The genotypic variation for lateral root density and length in rice could be used to improve its adaptations to nutrient and water-limited environments. Through screening in different growing media, it was found that nutrient solution screening exposed genotypic variation for S-type and L-type density, while only lateral roots of soil-grown plants varied in length. QTL mapping was used to identify markers linked to genotypic variation for lateral root traits. The QTL for L-type density on chromosome 5 had a major effect, accounting for 46% of the phenotypic variation. The identified markers provide opportunities for incorporating lateral root traits into a breeding program. Rating: 8/10

Summary: Contamination of paddy soils with arsenic can have toxic effects on rice plants and increase arsenic accumulation in grains. The uptake and detoxification of different arsenic species in rice is not fully understood. This study investigated the toxic effects of arsenite and arsenate on rice plants and the role of glutathione S-transferase in detoxifying arsenic. The results showed that arsenite was more detrimental to plant growth and lipid peroxidation than arsenate. Overexpression of glutathione S-transferase led to improved plant growth and lower lipid peroxidation under acute arsenite stress. Overall, arsenite was found to be more toxic to plants than arsenate and glutathione S-transferase has differential effects on plant reactions and tolerance to different arsenic species.

Summary: Tropospheric ozone has significant effects on the remobilization and allocation efficiency of aboveground biomass and nutrients in cereal crops. Long-term ozone exposure increases straw C:N ratio and affects grain C:N ratio. Grain N concentrations increase significantly under ozone stress, but N yield declines due to grain yield losses. Various indicators of N use efficiency are reduced, indicating reduced N absorption from soil and allocation from vegetative to reproductive organs. Straw C:N ratio is not suitable for predicting wheat productivity. Nitrogen harvest index (NHI) is not affected by ozone stress, but the relationship between harvest index (HI) and NHI is changed by elevated ozone concentration.
