Summary: Global warming and climate change are causing more frequent and intense extreme climate events, leading to significant damage to agricultural production. Recent studies have shown that the transcriptional responses of different crops to water deficit or heat stress are different from their responses to a combination of water deficit and heat stress. Furthermore, the reproductive growth phase of crops is more vulnerable to these stresses compared to the vegetative growth phase. Therefore, we conducted a transcriptomic analysis of soybean tissues under water deficit, heat stress, and a combination of both.

Summary: This study analyzed the physiological responses and transcriptome changes of two soybean varieties under drought stress. The results showed that the drought-tolerant variety had smaller stomata, higher ABA content, and better water use efficiency. Additionally, it had fewer differentially expressed genes and specific pathways related to drought tolerance. This study deepened our understanding of the drought resistance mechanisms in soybeans and provided valuable references for breeding drought-resistant soybeans.

Summary: This study found that exogenous sodium nitroprusside (SNP) improved the drought resistance of soybean leaves by increasing the NO content. It also affected the activity of nitrite reductase and nitrate reductase, as well as the activity of antioxidant enzymes and the content of osmomodulatory substances. This research provides a theoretical basis for improving drought-resistant cultivation of soybean.

Summary: This study utilizes transcriptomic and metabolomic data to uncover the metabolic regulation mechanisms of soybean seedlings under drought stress. Candidate genes that may contribute to differences in drought resistance are identified, and a large number of flavonoids involved in drought response are discovered. The study deepens the understanding of soybean drought resistance mechanisms and provides references for soybean drought resistance breeding.

Summary: In humid climates, waterlogging during the reproductive stage can significantly affect soybean growth, physiology, and yields. This study investigated the effects of waterlogging and subsequent reoxygenation on the soybean cultivar 'Asgrow AG5332'. Results showed that prolonged waterlogging negatively affected chlorophyll index, water potential, stomatal conductance, and photosynthetic rate. Decreased photosynthesis, leaf area, and nutrient availability led to lower biomass and seed yield. Waterlogged plants also exhibited altered reflectance characteristics, indicating changes in chemistry and pigment content. Understanding and integrating the findings from this study can help develop improved cultivars for waterlogging-prone areas.

Summary: In this study, key genes controlling heading date in winter wheat were identified through transcriptome analysis and genetic mapping. These genes showed differential expression in specific tissues and stages of transition and were associated with gibberellin synthesis reaction. These findings provide important clues for further understanding the regulatory mechanism of flowering time in winter wheat.

Summary: Studying the drought stress mechanism in soybean roots at the cotyledon stage using uniconazole led to insights into soybean stress physiology. Uniconazole effectively alleviated inhibition on root growth, reduced lignification of vessels, and strengthened osmotic adjustment and antioxidant systems, while also impacting gene expression related to drought tolerance. This research provides valuable information on drought resistance mechanisms in legumes and the mitigative effects of uniconazole on drought stress.

Summary: In this study, comprehensive comparative transcriptome analyses were conducted to explore the molecular mechanisms of soybean drought tolerance. The results revealed that drought-tolerant genotype Jindou 21 (JD) exhibited better adaptation and drought resistance compared to drought-sensitive genotype Tianlong No.1 (N1) through multiple signal transduction pathways, transcription factors, and stress-related proteins.

Summary: Drought stress has a significant impact on plant growth and productivity. Through transcriptome analysis, it was found that plants have a rapid and sustained response in root tissues to drought stress. The phosphatidylinositol signaling system is an important pathway in the early response to drought stress and may interact with auxin signaling.
