Summary: This study investigated the differential responses of super rice grain filling to low filling stage temperature (LT) and the regulative effect of nitrogen panicle fertilizer (NPF). It found that under LT or NPF treatments, the reduction of grain weight, seed setting rate, and filling rate were closely associated with suppressed starch biosynthesis rate in inferior seeds. Nanjing 9108 showed higher grain filling rates and lower variance compared to Nanjing 7, suggesting superior adaptability to LT and NPF due to its higher sink activities.

Summary: High temperatures during grain filling can decrease grain weight and amylose content but increase chalky area, protein content, and mineral concentrations in rice grains. Negative correlations were found between mineral contents and both grain weights and amylose contents of milled rice. Increases in grain chalky areas due to high temperatures can also lead to higher grain mineral contents.

Summary: Rice plants are highly sensitive to high-temperature stress, which greatly affects the yield and quality of high-quality hybrid rice. The impact of high temperatures during the booting and grain-filling stages on grain quality differs, with high temperatures during the grain-filling stage having a greater effect on grain chalkiness and viscosity parameters. Breeding and cultivation of high-quality hybrid rice should take into account the effects of high temperatures at different stages on both yield and quality.

Summary: The study revealed a negative interaction between elevated CO2 levels and short-term high temperatures on crop yield and quality. Elevated CO2 initially had positive effects on crop photosynthesis, but these benefits were reduced by high temperatures, leading to decreased grain setting and poor grain appearance quality. Adaptation measures against heat stress during reproductive and grain-filling periods are essential to mitigate the negative impacts of climate change on crop production.

Summary: This study found that rice glutelin is sensitive to temperature and nitrogen, and their interactions can affect glutelin accumulation during grain filling. Elevated temperature promotes the levels of pro-glutelin and application of nitrogen under warming increases the amount of α-glutelin. However, the increase in glutelin content worsens grain quality, particularly chalkiness and eating quality.

Summary: Heat stress during grain-filling stage has a negative impact on rice grain quality. This study investigated the effects of high nighttime temperature (HNT) on grain chalkiness formation in rice at the early grain-filling stage. It was found that HNT treatment increased grain chalkiness, with a greater effect observed in one rice variety compared to another. The study also revealed that HNT treatment affected photosynthetic rate, antioxidant enzyme activity, hormonal levels, enzymatic activities related to starch biosynthesis, and filling rate in grains, leading to changes in the structure and arrangement of starch granules and ultimately causing grain chalkiness occurrence.

Summary: In this study, the effects of OsCIPK17 gene on agronomic traits, photosynthetic parameters, transcriptome, and gene expression were analyzed using mutant cipk17 and Nipponbare in field experiments. The results showed that OsCIPK17 was expressed in multiple organs and involved in root, stem, and leaf growth. Knockout of OsCIPK17 resulted in a decrease in grain filling rate and final grain weight, as well as reduced efficiency of Photosystem II. Enrichment analysis and fluorescence analysis further confirmed the functions of OsCIPK17 in photosynthesis and metabolism-related gene expression.

Summary: There is an unprecedented increase in low-temperature stress (LTS) during the post-heading stages in rice due to recent climate changes. Quantifying the impact of LTS on yields is vital for understanding the effects of climate change on crop production and developing mitigation strategies. This study found that LTS for 3 days had minimal effect on grain yield, but LTS lasting between 6 and 9 days significantly reduced yields of two rice cultivars, with one being more cold tolerant than the other. Additionally, LTS decreased grain filling rates and prolonged the grain filling duration of both cultivars, with a strong correlation between yield loss and various grain filling parameters under LTS.

Summary: This study investigated the regional impacts of temperature increase and heat stress on wheat in China using a crop model and found that heat stress was more severe in cooler northern sub-regions compared to warmer southern sub-regions. Climate warming is projected to increase heat stress events in frequency and extent, especially in northern sub-regions, but surprisingly higher warming did not result in more yield-impacting heat stress.

Summary: In recent decades, the increase of N fertilizer inputs has contributed to the wheat production increase in the largest wheat producing region of China. However, the efficiency of N fertilizer has decreased and led to environmental problems. This study conducted wheat experiments and found that soil native N and fertilizer N were important sources for wheat N accumulation. Irrigation at jointing and anthesis promoted wheat N accumulation. The contribution of pre-anthesis N translocation to grain N increased with total N rate but decreased with irrigation.

Summary: Current wheat crop management practices in the Nile Delta are unsustainable due to overuse of limited water resources. This study investigated opportunities to maximize wheat yield and resource efficiency, including water use efficiency, nitrogen use efficiency, and solar radiation use efficiency. Three wheat simulation models were calibrated and evaluated for modern spring wheat cultivars across field experiments, and then used to simulate yield, efficiency, and resource use under different conditions. The study found that increasing nitrogen fertilizer improved yield, water use efficiency, and radiation use efficiency, but with diminishing returns. Irrigation at 80% depletion of plant available water was found to be the optimal treatment, minimizing water use with a slight decline in yield and efficiency. The study suggests that, for sustainable wheat production in the Nile Delta and other irrigated arid regions, high water use and nitrogen use efficiency may be more critical than maximizing yield.

Summary: With increasing global warming, extreme heat stress frequently occurs and significantly reduces crop yield. Previous studies have focused on the formation of grain yield under heat stress, but little attention has been paid to the redistribution of carbohydrates and nitrogen caused by imbalanced sink-source relationships. Experimental data from multiple years, with different heat stress intensities, durations, and rice varieties, showed that rice stems can act as storage organs and accumulate large amounts of carbohydrates and nitrogen during the grain filling stage after short-term extreme heat stress at flowering. This indicates that stems may become alternative harvest organs under climate change, but accurate assessments for adaptation strategies are needed. We improved the simulation of biomass and nitrogen accumulation in different rice organs under heat stress by re-evaluating the sink-source relationship and using the RiceGrow model. We quantified the nitrogen filling process in stems after grain filling termination, and simulated the delay of leaf senescence by considering the leaf nitrogen distribution within the canopy under heat stress. The improved model explains the cause and effect of unusual carbohydrate and nitrogen accumulation in rice under heat stress, and can be a useful tool for adaptation strategies under climate change.

Summary: Extreme temperature events caused by global climate change have a significant negative impact on rice yield. Heat stress at different growth stages affects rice yield and yield components differently. Heat stress at the booting and flowering stages has a better compensatory effect on yield loss compared to heat stress at the flowering stage. The variation in yield components is also influenced by different stages of heat stress.
