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 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: This study identified a new R2R3-MYB gene, ThRAX2, which plays an important role in plant development and response to environmental stresses. ThRAX2 enhances Cd tolerance by specifically binding to the MYB-T motif and regulates the expression of downstream genes involved in ion homeostasis, transport, and protein activity. This finding provides a genetic and theoretical basis for the use of transgenic plants in the future bioremediation of Cd-contaminated land.

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: 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: 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.

Summary: Ethylene response factors (ERFs) are plant-specific transcription factors that positively regulate stress responses. In tomato, SlERF1, SlERF3b, and SlERF5 are differentially upregulated under various stress conditions, suggesting their role in modulating defense responses. Overexpression of SlERF3b and SlERF5 in transgenic tomato plants enhances stress tolerance by upregulating stress-related genes and promoting early flowering. Additionally, SlERF3b and SlERF5 positively regulate immune responses against Botrytis cinerea by modulating JA/ET signaling pathways.

Summary: Cadmium (Cd), a nonessential and toxic metal, accumulates in plant tissues and limits crop growth. The role of R2R3-type MYB transcription factor ThDIV2 in regulating Cd tolerance in T. hispida was investigated. ThDIV2 was found to be suppressed under Cd stress and overexpression of ThDIV2 resulted in increased ROS and H2O2 content, decreased antioxidative enzyme activity, and repression of the expression of ThAO1, ThAO2, ThAO3, ThSOD1, ThSOD2, and ThSOD3. ThDIV2 directly bound to the promoters of ThAO1 and ThAO2. These findings suggest that ThDIV2 regulates Cd tolerance in T. hispida by modulating ROS and antioxidative capacity.

Summary: This study conducted a genome-wide identification of Q-type C2H2 zinc finger protein (ZFP) genes in grapevine genomes and explored their characteristics and functions. The results showed that the physical and chemical properties of these ZFPs exhibited differences, but they were all hydrophobic and stable proteins. The phylogenetic analysis revealed the evolutionary relationships among these genes and their distribution on different chromosomes. The study also demonstrated the involvement of these genes in response to hormones and low-temperature stress using gene expression and localization experiments. Overall, this research provides valuable insights into the response mechanisms of grapes to exogenous hormones and low temperatures and lays a foundation for future molecular breeding.
