Summary: Optimum growing temperature is crucial for maximum crop yield. This study evaluated the effect of heat stress on agronomic and physiological attributes of Green Super Rice (GSR) at the flowering stage. Genotypes showed significant variations in all studied parameters except normalized difference vegetative index (NDVI). Heat stress significantly affected grain yield, plant height, straw yield, harvest index, and cell membrane stability in most genotypes. Outperforming NGSR-16 and NGSR-18 under heat stress suggests their potential as parent lines for developing heat-tolerant rice.

Summary: This study investigated genotypic variations in stem reserve mobilization (SRM) in wheat and their influence on yield sustainability under drought and heat stress environments. Results showed that water-deficit stress significantly increased SRM, while heat stress conditions reduced SRM. SRM exhibited a positive correlation with grain weight under all stress treatments, but the yield protection mediated by SRM was uncertain under heat stress and combined water-deficit and heat stress treatments. The wider genetic variability for the SRM trait could be used to improve wheat yield under drought stress conditions.

Summary: Delayed sowing of maize hybrids can lead to decreased yield potential due to various factors such as poor crop stand, root proliferation, nutrient uptake, and dry matter accumulation. This study evaluated the performance of five recent maize hybrids under timely and late sown conditions and found that timely sowing resulted in higher grain and stover yields. The hybrids AH-4271 and AH-4158 exhibited superior performance in terms of grain yield, dry matter accumulation, and nutrient acquisition. Root morphological traits were also improved in these hybrids. Overall, timely sowing and the selection of appropriate hybrids based on stress tolerance indices can lead to increased yields and better resource utilization.

Summary: This study aimed to assess the feasibility of water-saving irrigation measures for winter wheat cultivation in Gaocheng and Qingyuan, China. The effects of different irrigation and nitrogen application treatments on yield increase were investigated through long-term positioning experiments. The results showed that soil water storage before sowing and precipitation during the growth period significantly influenced the effect of supplementary irrigation at the anthesis stage on winter wheat yield. A reference value of 31.9 mm precipitation from the jointing stage to the anthesis stage was found to be suitable for irrigation at the anthesis stage when there is sufficient soil water storage before sowing.

Summary: A two-year field experiment in Iran explored the use of wheat cultivar mixtures with different ripening patterns to mitigate post-anthesis water stress. Results showed that under stressful conditions, heterogeneity in ripening pattern of mixtures diminished, leading to reduced differences in grain yields and agronomic characteristics. While some casual beneficial effects were observed, they were not consistent across all conditions.

Summary: This study found that the OsSAPK3 gene in rice is upregulated under drought, salt, PEG, and ABA stress. This gene plays a crucial role in drought stress by affecting osmotic adjustment, ROS detoxification, and expression of ABA-dependent and ABA-independent dehydration-responsive genes. Moreover, OsSAPK3 improves rice yield by indirectly regulating tiller number and grain size.

Summary: Changing climate conditions are affecting the quality and yield of the United States rice export industry, particularly for uncharacterized hybrid varieties under high heat episodes and increasing atmospheric CO2 levels. The study found that high temperatures significantly reduced rice yield, with a larger decrease at the 8C temperature increase. Elevated CO2 levels had a slight positive effect on yield and harvest index, primarily due to an increase in single grain weight. However, the proportion of biomass allocated to panicles decreased at the higher temperature. Breeding efforts for climate resiliency should focus on traits related to hybrid vigor and resistance to high temperatures.

Summary: Iron and zinc are recognized as clinically significant micronutrients globally, but major staple crops lack sufficient levels of these elements. Scientists are working on enhancing iron and zinc accumulation in grains through conventional and next-generation techniques. While conventional breeding has had success in increasing zinc concentration, it has been less successful with iron concentration. Precise editing using CRISPR-Cas9 shows promise in improving iron and zinc content in cereal grains without adverse effects.

Summary: This study identified and analyzed 33 putative CPA genes in tomato and found that they play a crucial role in maintaining ionic balance and pH homeostasis, promoting plant development, and responding to salt stress. Further analysis revealed the characteristics of CPA genes in terms of gene structure, distribution pattern, and co-localization. The diverse functions of these CPA genes provide comprehensive information for exploring new candidate genes for salt tolerance in tomato.

Summary: This study identifies the role of the wheat PSTOL1 genes in P uptake, root architecture, and efficient plant growth. The researchers discovered 22 PSTOL1 orthologs in the wheat genome and observed differential expression patterns in different tissues under different phosphorus regimes. Some of these genes were found to be co-localized with phosphorus starvation-related QTLs, suggesting their potential role in phosphorus use efficiency. This comprehensive study has important implications for devising sustainable strategies for wheat crop production and adaptation to phosphorus insufficiency.

Summary: Development of nutrient efficient cultivars relies on effective identification and utilization of genetic variation. In this study, we characterized a set of pre-breeding lines (PBLs) and found significant variation in various traits among PBLs at different nitrogen doses. Plant height, tiller number, and biological yield showed positive correlation with nitrogen application. Genetic association analysis identified several marker-trait associations, with some markers explaining a large proportion of phenotypic variance. Additionally, a number of PBLs exhibited higher grain yield compared to checks, indicating their potential as donors for improving plant nitrogen use efficiency.

Summary: Among toxic heavy metal(loid)s, cadmium and arsenic have devastating effects on crop productivity and human health. Detoxification mechanisms for Cd and As in plants proceed via a common pathway involving glutathione, although their modes of toxicity differ. Exposure of Brassica juncea seedlings to Cd and As stress resulted in mostly distinct, but partly overlapping responses, affecting growth and biochemical responses. This study provides valuable insights for sustainable plant growth strategies on As and Cd polluted soils.
