Summary: In this study, 43 putative drought-induced NAC genes were identified in wheat, with TaNAC48 showing significantly increased expression under drought and promoting drought tolerance through crosstalk with the ABA signaling pathway. These results suggest an essential role of TaNAC48 in mediating drought stress responses in wheat.

Summary: This study comprehensively explored how the environment affects wheat yield and protein content response to drought through meta-analysis. The results showed that drought significantly decreased wheat yield and protein yield, but increased protein content and nitrogen content. The responses of yield and nitrogen content to drought were mainly related to the drought type, while protein yield was mainly related to precipitation. Sandy soils and high nitrogen application level mitigated the negative effects of drought, and winter wheat showed better drought resistance than spring wheat.

Summary: A risk-based approach is more meaningful for quantifying the effects of drought on crop yield, but there is a lack of research on drought and crop yields at a local scale. This study used a probabilistic method to explore the yield loss probability under various drought conditions in New South Wales wheat belt. The findings have important implications for evaluating the agricultural impact of drought in drought prone areas.

Summary: Genetically enhancing drought tolerance and nutrient use efficiency in wheat can lead to sustainable and stable production in drought-prone areas. This study successfully developed wheat plants with improved drought tolerance and nitrogen use efficiency by introducing the GmTDN1 gene, resulting in significantly higher yields under both drought and nitrogen-deficient conditions.

Summary: In this study, the JcTAW1 gene from Jatropha curcas was introduced into tobacco, resulting in increased lateral branches and yield of the transgenic plants. The transgenic plants also showed higher plant height, longer roots, and better drought resistance. Transcriptome analysis revealed that JcTAW1 may promote glucose metabolism while suppressing the DNA repair system.

Summary: Drought is a major limiting factor for wheat productivity, and it is expected to have an increasing negative impact on crop growth in arid areas due to climate deterioration. In this study, the wheat TaXTH gene family was studied, and it was found that TaXTH genes play a role in regulating drought response in wheat. The expression of TaXTH12.5a enhanced drought tolerance in Arabidopsis, further supporting the role of XTH genes in regulating drought stress response in plants.

Summary: The combination of elevated atmospheric carbon dioxide concentration and drought will significantly impact wheat production and quality. The response of wheat genotype phenology to elevated carbon dioxide and drought has not been studied before. This study found that elevated carbon dioxide had a significant effect on plants grown under drought, particularly on the booting stage and carbon assimilation rate. However, there was no effect on transpiration rate and grain protein content. The complex water x carbon dioxide x genotype interaction highlights the need to account for multiple factors when modeling wheat response to future climate change.

Summary: The primary goal of modern wheat breeding is to develop new high-yielding and widely adaptable varieties. A genome-wide association analysis of 502 wheat accessions identified 51 yield-related and nine drought-resistance-related QTL, explaining 2.23 - 7.35% of the phenotypic variation. Eight stable SNPs associated with phenotypic stability were discovered, along with several novel QTL for yield-related traits. Three linked SNPs were transformed into molecular markers, facilitating the discovery of promising SNPs for breeding new wheat varieties with desirable alleles.

Summary: This study used a remote sensing-based agricultural drought-affected area change index (ADAC) to assess the performance of drought mitigation schemes in major wheat-growing regions worldwide. The results showed significant regional differences in the effectiveness of drought mitigation measures, with China and India leading the way. The study also found that irrigation was the main drought mitigation measure in dryland, while conservation tillage played a significant role in both dry and wet areas.

Summary: In this study, it was found that TaSNAC4-3D is induced in wheat leaf tissue under drought stress. Overexpression of TaSNAC4-3D increases oxidative damage and promotes cell death in wheat leaf tissue, resulting in decreased drought tolerance.

Summary: The bHLH transcription factor CgbHLH001 from Chenopodium glaucum was found to confer drought tolerance in maize by accumulating soluble sugar and proline contents, as well as increasing the activities of antioxidant enzymes. These findings suggest that CgbHLH001 has the potential for improving drought resistance in maize breeding.

Summary: This study identified six AhMYB44 genes in cultivated peanut, which showed different functions and expression patterns under drought stress. AhMYB44-11 played a positive role in drought tolerance by increasing stress-related gene expression and osmolyte accumulation, while AhMYB44-16 negatively regulated drought tolerance through ABA-dependent stress response pathways.
