Summary: Researchers successfully identified a mutant allele in a fatty acid desaturase gene that is responsible for the high oleic acid content in certain cotton accessions. They also found that the missing amino acid residues in the mutant protein are not essential for enzyme activity but are necessary for proper subcellular targeting. This discovery will facilitate breeding programs to introduce the high oleic acid trait into other cotton varieties.

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: 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 use of exogenous melatonin can improve the growth and quality traits of rice under high temperature, alleviating the adverse effects of high temperature on rice yield and quality. Melatonin enhances photosynthetic and heat-resistance properties, stabilizes the chain length distribution of rice starch, and improves rice quality.

Summary: Temperature and solar radiation are key drivers of grain weight and composition in crops like sunflower. Temperature affects these traits through both indirect effects mediated by solar radiation interception and direct effects. Studies on sunflower hybrids showed that grain weight responds to temperature due to reductions in solar radiation, while oil content is affected by temperature regardless of solar radiation effects.

Summary: Recent research has identified OsSFq3 as a candidate gene contributing to spikelet fertility and grain quality under high temperature conditions in rice. This gene, along with several other candidate genes related to starch components, showed high expression levels under high-temperature treatment. The findings suggest that OsSFq3 and related genes could be utilized in breeding high-quality and -yield rice varieties resilient to high temperatures.

Summary: GH4169 superalloy fibers with ultra-high strength and ultra-fine grain (UFG) were fabricated by cold de-formation and low temperature annealing, providing a simple and effective method for preparation of UFG materials. The grain size of the fibers was reduced to 42 nm after annealing at 450°C for 30 min, leading to an increase in the tensile strength to about 2.05 GPa. By controlling the annealing condition, the superalloy fibers were further refined, resulting in higher strengthening effects.

Summary: In this study, high oleic acid peanut mutant alleles were introgressed into two popular peanut cultivars through markers-assisted selection and backcrossing. The resulting lines showed significantly increased oleic acid content without affecting kernel mineral and vitamin composition. The introgression lines with improved oleic acid content and high pod yield potential could be released for commercial cultivation.

Summary: The physicochemical indexes of starch from six rice varieties showed significant differences under high temperature during grain filling stage, with five indexes being more sensitive to high temperature. These indexes can be considered as key indicators to evaluate the high temperature tolerance of the rice varieties. The experimental results indicated a range of high temperature tolerance among the six varieties, from strong to weak, and the regression equation suggested that the tolerance could be preliminarily evaluated using key physicochemical indexes of starch.

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: Dietary trans fatty acids (TFA) from industrial partial hydrogenation are still a concern, with high oleic (HO) oils seen as an effective strategy to replace partially hydrogenated vegetable oils. Among HO oils, HO sunflower has been identified as the best option in terms of oxidative stability and beneficial effects on consumer health.

Summary: Film mulching ridge-furrow planting (RF) is an important dry farming mode for wheat, but it often causes lodging due to lignin accumulation in the stems. This study investigated the effects of regulating the population distribution on lodging occurrence in wheat and found that adjusting the population distribution can improve lodging resistance by enhancing the mechanical properties of the stems and promoting lignin synthesis and accumulation. The light environment plays a crucial role in lignin biosynthesis and lodging resistance.

Summary: This study conducted a field experiment to test different methods and species of cover crops. The results showed that early establishment of cover crops, specifically direct sowing or sowing 10 days before harvest, had a positive impact on biomass formation and weed suppression. The performance of cover crops varied depending on the species, sowing date, and weather conditions, but a diverse cover crop mixture showed more stable performance under variable weather conditions.

Summary: This study used simulation experiments to evaluate the effects of planting time, nitrogen rate, and crop variety choice on potato productivity in Ethiopia. The results showed that shifting planting time forward and changing the nitrogen application rate had greater productivity benefits than switching varieties. In the mid-century climate period, early planting of medium and long maturity varieties with higher nitrogen rates showed potential adaptation benefits.

Summary: This study aims to establish critical nitrogen dilution curves (CNDC) for maize and diagnose the nitrogen status under different mulching planting patterns. The results showed no significant differences in CNDC and its estimated parameters across years and mulching planting patterns, suggesting the establishment of a universal CNDC model for maize nitrogen diagnosis.

Summary: The intensification of Mediterranean farming systems has had negative impacts on the environment, but agroforestry systems can address these issues. This study developed a practical methodology to assess the sustainability of Mediterranean agroforestry systems and found that they provide agro-environmental benefits and economic profitability, although they also require increased workload.
