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: This study investigated the response of starch and sugar metabolism to drought stress during wheat grain filling. The grain filling rate of two elite wheat varieties under two water treatments was simulated using logistic regression analysis. The results showed that drought stress mainly affected the early period of grain filling through changes in sucrose and soluble sugar contents, sucrose synthase activity, starch content, and the activity of key starch synthases. Differential expressed proteins related to carbohydrate metabolism, particularly starch and sugar metabolism, were upregulated in response to drought stress. The study provides insights into the mechanisms of drought tolerance in wheat.

Summary: The study compared the genome-wide transcriptome of two wheat cultivars in response to drought and salinity stresses, identifying specific genes associated with tolerance in the drought/salt-tolerant cultivar. Functional enrichment analysis revealed differences in gene expression related to ROS detoxification, defense, phytohormones, and signal transduction pathways between the two cultivars under stress conditions. These findings suggest potential molecular bases for breeding drought and salinity tolerant wheat cultivars.

Summary: In this study, the TaCLC gene family of wheat was screened and analyzed. It was found that the expression levels of these genes were up-regulated under low nitrogen stress and salt stress conditions, except for the TaCLC-c2 cluster genes. Furthermore, some TaCLC genes were found to have anion transport functions in yeast. This study provides a preliminary reference for better understanding nitrate nitrogen transportation in wheat.

Summary: This study analyzed the genomics of adaptive traits in bread wheat landraces through genome-environment associations. The results identified several genes and proteins involved in the response and tolerance to abiotic stress, with some genes mediated by auxins, abscisic acid, ethylene, salicylic acid, and jasmonates. Additionally, proteins associated with heat stress, drought, and cell wall functions were identified.

Summary: Comprehensive analysis of alkalinity stress-responsive long non-coding RNAs (lncRNAs) in wheat revealed the presence of a lncRNA-miRNA-target-mRNA network and an alkali response-related lncRNA-target-mRNA association network. The study demonstrates that lncRNAs may play different roles under alkaline stress conditions.

Summary: In this study, 18 TaCHYR genes were identified and classified in wheat. The results showed that these genes play important roles in the growth, development and stress responses of wheat. The expression of certain TaCHYR genes inhibited the growth of yeast cells under salt and dehydration stress. Furthermore, gene ontology annotation, protein interaction and miRNA regulatory network analysis provided candidate genes for further functional investigations.

Summary: The study identified five resistance loci for Septoria tritici blotch in wheat, with some potentially derived from the Mandub cultivar, and discovered a possibly new resistance locus. It also demonstrated that the Mandub cultivar is a potential good source of STB resistance and could be utilized in breeding programs.

Summary: Thermosensitive cytoplasmic male sterile (TCMS) lines play a crucial role in wheat breeding. MiRNAs can regulate gene expression levels by inhibiting gene translation. YS3038, a wheat TCMS line, was studied for its fertility conversion mechanism through examination of abortion characteristics, miRNA regulation patterns, and target genes.

Summary: This study investigated the drought-tolerant mechanisms of Enterobacter bugandensis WRS7 in wheat plants. The results showed that WRS7 possessed various plant growth-promoting properties and alleviated the negative effects of drought stress in wheat plants by regulating metabolic genes. This research highlights the potential of using PGPR for improving crop resilience to abiotic stressors.

Summary: The highly conserved Sal1 gene has been edited in hexaploid wheat using precise gene editing techniques. The resulting mutant wheat plants with disabled Sal1 genes exhibit slower growth under drought conditions and slower senescence under water limiting conditions. The use of multiplexed gRNAs enabled effective targeted gene editing of the Sal1 gene family.
