Summary: The COL-like transcription factor ThCOL2 in the woody halophyte Tamarix hispida plays a significant role in the response to salt stress, particularly in regulating the expression levels under salt stress and ABA treatment. ThCOL2 overexpression enhances salt tolerance by regulating ROS removal and enzyme activity, indicating its potential as a candidate gene for improving salt tolerance. Further analysis of downstream genes regulated by ThCOL2 will provide insights into the salt tolerance regulatory network.

Summary: The study revealed that ThEIL1, as a transcription factor, plays a key role in salt tolerance in Tamarix hispida. It elevates osmotic potential by regulating the biosynthesis of trehalose and proline, and enhances reactive oxygen species scavenging capability by controlling the expression of genes related to SOD and POD.

Summary: Trehalose is a non-reducing disaccharide that enhances the resistance of organisms to various abiotic stresses. This study found that the ThTPS gene can respond to abiotic stress in T. hispida, such as salt and drought, and overexpression of this gene significantly improves salt and osmotic tolerance.

Summary: The study revealed that overexpression of ThSOS3 enhances antioxidant enzyme activity, improves ROS scavenging capability, and reduces lipid peroxidation in cell membranes, resulting in better growth and response of plants under salt stress. This provides a foundation for further understanding the role of ThSOS in salt tolerance mechanisms in Tamarix hispida.

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: This study isolated and characterized 11 Stress associated proteins (SAPs) from T. hispida, and found that most ThSAPs exhibited transcriptional responses to abiotic stresses and phytohormones, with ThSAP6 being significantly induced by salt stress. Function analysis revealed ThSAP6 as a positive regulator of salt stress response, showing potential for biotechnological approaches to improve salt tolerance in plants.

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: Salinity and heavy metal pollution have a severe impact on plant growth. Tamarix hispida (T. hispida) has the potential to remediate soil polluted by salt and heavy metals. This study explored the response mechanisms of T. hispida to stresses caused by NaCl, CdCl2 (Cd), and combined CdCl2 and NaCl (Cd-NaCl). The antioxidant system showed changes under all three stresses. NaCl inhibited the absorption of Cd2+. Significant differences were observed in transcripts and metabolites among the three stress responses. Notably, linoleic acid metabolism pathway was enriched in both differentially expressed genes (DEGs) and differentially expressed metabolites (DEMs) under Cd stress.

Summary: The CLE family of small secreted proteins plays important roles in plant development and stress responses. In this study, 84 members of the CLE family were identified in tobacco and related species. These CLE members formed 9 subgroups and several of them showed induced expression upon abiotic stress treatments. Synthetic peptides of some CLEs were also found to enhance tobacco's tolerance to osmotic and salinity stresses.

Summary: Tamarix hispida, a halophytic plant, shows great potential in tolerating cadmium pollution in soil, yet the molecular mechanisms involved are still poorly understood. In this study, RNA-seq technique was used to analyze the transcriptomic changes of T. hispida under cadmium stress, revealing the potential genes and pathways associated with cadmium tolerance. These findings could contribute to the understanding of molecular mechanisms governing cadmium resistance.
