Summary: The study identified a novel heat shock transcription factor gene, ZmHsf08, in maize, which negatively regulates responses to salt and drought stresses in the plant. Overexpression of ZmHsf08 resulted in increased sensitivity to salt and drought stresses, with higher ROS levels and MDA contents compared to wild-type plants. Analysis also showed that ZmHsf08 negatively regulates stress/ABA-responsive genes under salt and drought stress conditions.

Summary: The study demonstrates that the McHB7 transcription factor plays a positive role in improving plant salt tolerance in Mesembryanthemum crystallinum (common ice plant). Overexpression of McHB7 in ice plant leads to increased activities of superoxide dismutase and peroxidase, as well as higher water content under high salinity stress. Proteomics analysis reveals that the proteins upregulated in McHB7-overexpressing ice plants under salt stress are involved in transport regulation, catalytic activities, biosynthesis of secondary metabolites, and response to stimulus.

Summary: Salt stress inhibits plant growth and decreases crop yield. This study identified enriched pathways and genes affected during salt treatment using mRNA sequencing. The AP2/ERF transcription factor SmERF1 was found to be significantly upregulated by salt stress and played a crucial role in the response to salt stress in eggplant. Silencing SmERF1 increased plant susceptibility to salt stress and reduced the expression of defense-related genes.

Summary: In this study, the FAR-RED ELONGATED HYPOCOTYLS3 (FHY3) and FAR-RED IMPAIRED RESPONSE1 (FAR1) genes were identified and characterized in Eucalyptus grandis. The study analyzed the gene structures, protein characteristics, 3D models, phylogenetic relationships, and promoter cis-elements of the FAR1/FHY3 gene family. The results showed differential gene expression and response to salt and temperature stresses. These findings contribute to the understanding of the evolution and function of the FAR1/FHY3 genes in E. grandis.

Summary: Soil salinity is a global problem that severely limits crop growth and yield, and poses a major challenge to plant breeding. The bZIP transcription factors are widely distributed and conserved regulators of plant responses to various stimuli. They play important roles in biological processes and abiotic and biotic stress responses.

Summary: Drought and salinity have negative effects on plant growth and productivity, but the anthocyanin biosynthesis system can activate plant stress-tolerance mechanisms and enhance drought and salt tolerance. This review focuses on the molecular and biochemical mechanisms of anthocyanins in acquired tolerance to drought and salt stresses, as well as the role of abscisic acid and abscisic-acid-miRNA156 in regulating drought-induced anthocyanin production. Additionally, it summarizes the research progress on transcription factors involved in anthocyanin biosynthesis and the development of salt and drought tolerance. Finally, the recent progress in using modern gene manipulation technologies to develop anthocyanin-enriched plants with enhanced tolerance to drought and salt stresses is discussed.

Summary: The current challenges of rising food demand, climate change, and farmland degradation exert enormous pressure on agricultural production. Worldwide soil salinization necessitates the development of salt-tolerant crops, making it important to examine the genetic resources of soybean for crop improvement based on functional genomics. This review discusses the different salt tolerance mechanisms employed by soybean and the strategy for selecting salt tolerance genes for crop improvement.

Summary: The epithelial/mesenchymal transition (EMT) is associated with tumor metastasis. Cancer cells have high levels of antioxidants, such as the Trx/TrxR and GSH/Grx systems, to counteract oxidative and nitrosative stress. These systems play a significant role in EMT signaling and cancer cell progression.

Summary: This study reveals that the tomato WRKY transcription factor WRKY57 negatively regulates salt stress response by attenuating the transcription of salt-responsive genes and an ion homeostasis gene. The VQ-motif containing proteins, SlVQ16 and SlVQ21, interact with WRKY57 and modulate tomato's resistance to salt stress, with SlVQ16 acting positively and SlVQ21 acting negatively. The SlWRKY57-SlVQ21/SlVQ16 module is also involved in the jasmonate pathway.
