Summary: The salt-tolerance of transgenic soybean was improved by over-expressing AhBADH gene from Atriplexhortensis, as demonstrated through molecular analysis and field experiments. The introduction of salt-tolerance genes into transgenic crops is an effective strategy to increase productivity under salt stress conditions. However, there are limited reports on field-tested transgenic cultivars. This study showed that AhBADH from Atriplexhortensis confers salt tolerance when transformed into soybean and the transgenic lines with enhanced salt tolerance are undergoing biosafety assessment.

Summary: In this study, a salt-inducible NAC gene PsnNAC090 was successfully isolated and found to play an important role in plant development and stress response. Transient transformation experiments confirmed the protein localization in the cell membrane, cytoplasm, and nucleus. Further experiments revealed that PsnNAC090 enhances salt and osmotic tolerance by increasing reactive oxygen species scavenging and reducing lipid peroxide content. These findings suggest that PsnNAC090 is a potential candidate gene for stress response.

Summary: Desert moss Syntrichia caninervis is an excellent plant material for mining resistance genes, with the ScALDH21 gene from S. caninervis conferring tolerance to salt and drought in cotton. The overexpression of ScALDH21 in cotton enhances the expression of stress-responsive genes, improves photosynthesis and carbohydrate metabolism, and scavenges reactive oxygen species, thereby increasing cotton's resistance to salt stress.

Summary: This study found that high expression of SmZIP8 in Salix matsudana can enhance the tolerance of tobacco to Cd stress, reducing cell damage, raising mitotic indices, and reducing chromosome aberration rates. Meanwhile, transgenic tobacco also showed increased photosynthetic capacity and activated antioxidant enzymes, indicating enhanced physiological tolerance to Cd.

Summary: In this study, a novel WRKY gene called GsWRKY23 was identified and found to be specifically upregulated in salt-tolerant soybean seedlings. The physiological functions and mechanisms of GsWRKY23 were investigated using transformations of soybean and Arabidopsis plants. The results showed that GsWRKY23 plays a role in regulating ionic homeostasis to improve salt tolerance.

Summary: Salinity is a major abiotic stress that affects crop yield and food supply in saline soil areas. Wheat, being the main crop in these areas, has developed various strategies to enhance salt tolerance through conventional breeding approaches and new techniques such as gene identification, gene stacking, and utilization of wild relatives.

Summary: MsCML46 enhances tolerance to abiotic stresses by regulating stress-related gene expression, optimizing osmolytes levels, and antioxidant enzyme activity. It binds free Ca2+ to promote signal transduction and maintain higher K+/Na+ ratio, protecting intracellular homeostasis under sodium ion toxicity.

Summary: The transient expression of the maize WUS ortholog ZmWus2 caused severe leaf necrosis in tobacco leaves. Transcriptomic and metabolomic analyses revealed the active metabolism of inositol trisphosphate and glycerol-3-phosphate, upregulation of plant hormone signaling, and downregulation of photosystem and protein folding pathways. Additionally, the study identified the regulation of transcription factors such as ethylene-responsive factors, basic helix-loop-helix factors, and MYBs by ZmWus2. These findings contribute to the understanding of the mechanisms underlying WUS ectopic expression and can inform future genetic transformation strategies.

Summary: The study identified multiple salt tolerance genes in Tamarix hispida through yeast expression system and high-throughput sequencing, demonstrating their reliability in enhancing plant salt tolerance. The research also observed higher expression levels of identified genes in roots under salt stress, with a significant proportion belonging to 'response to stimulus' category. The findings suggest that processes such as protein translation, osmotic adjustment, antioxidant defense, and maintenance of cellular functions play crucial roles in salt tolerance mechanisms.

Summary: The genes encoding bacterial cold shock proteins A (CspA) and B (CspB) isolated from Escherichia coli show 100% homology with gene sequences from other bacterial species. In silico analysis reveals eukaryotic conserved cold shock domain (CSD) and ribonuclease-binding domain (RBD) indicating a role in RNA binding and temperature stress tolerance. Overexpression of these genes in rice enhances growth under high salt and drought stress conditions.

Summary: CaNAC46 is an important transcription factor that regulates plant resistance to abiotic stresses such as drought and salinity by activating ROS-scavenging enzymes and enhancing root formation. The regulatory mechanisms controlling this NAC transcription factor appear to be conserved between Arabidopsis thaliana and pepper.
