Summary: This study investigated the gene expression of Urochondra setulosa leaves at different salt concentrations using transcriptomics. The findings suggest that the plant regulates ion homeostasis and signaling through transcription at high salt concentrations. Furthermore, genes related to salt stress response were identified, providing insights into the mechanisms of plants in coping with extreme saline conditions.

Summary: This study further analyzed the transcriptional changes in genes related to the ROS scavenging system and important regulatory mechanisms in A. canescens under saline conditions using RNA sequencing data. The results showed that differentially expressed genes were involved in signal transduction, oxidative stress, oxidoreductase activity, protein kinase activity, transcription factor activity, and plant hormone signal transduction. Additionally, genes related to SOD, the AsA-GSH cycle, the GPX pathway, PrxR/Trx, and the flavonoid biosynthesis pathway were found to be upregulated, indicating their roles in scavenging excessive ROS and maintaining cell membrane integrity. Moreover, transcription factor genes and protein kinase genes were also induced, suggesting their involvement in regulating salt-responsive genes and salt signal reception/transduction, respectively. These findings provide valuable genetic resources for enhancing salt tolerance in salt-sensitive plants, especially forages and crops.

Summary: This study evaluated the salt tolerance of four olive cultivars and identified key genes involved in salt stress response. The results showed that Koroneiki was the most salt-tolerant cultivar, while Fadak86 and Picual were the most susceptible ones. The expression analysis of candidate genes suggested the important roles of OeNHX7, OeP5CS, OeRD19A, and OePetD in activating a salt tolerance mechanism.

Summary: A. canescens is a halophytic forage shrub with strong adaptability and high feeding value, which has great potential in disturbed lands in arid and semiarid regions. However, its application values are not widely recognized in some countries, such as China, and a comprehensive understanding and promotion are needed.

Summary: This study compares the resistance of halophytes to cadmium stress and finds that they can restore cellular homeostasis by activating antioxidant defense mechanisms and accumulate high amounts of Cd in leaves. These plants may be good candidates for Cd phytoextraction in the presence of low pollutant concentrations.

Summary: Soil salinity is an important environmental problem that affects plant growth and crop productivity. By studying the halophytic plant Sesuvium portulacastrum, it was found that this plant possesses specific gene expressions, physiological mechanisms, and metabolic pathways that enable it to convert saline soils into arable land under high concentrations of salt. These findings are significant for addressing issues related to saline soils.

Summary: An integrated transcriptome and proteome analysis approach was used to identify the salt tolerance mechanisms of Panicum antidotale. Under low salinity levels, upregulated genes and proteins were involved in salt resistance strategies, while downregulated genes and proteins were related to energy generation. High salinity levels led to inhibiting biomass accumulation by altering expression of genes involved in various metabolic pathways.

Summary: Priming-mediated stress tolerance in plants stimulates defense mechanisms and enables plants to cope with future stresses. Seed priming has been proven effective for tolerance against abiotic stresses; however, underlying genetic mechanisms are still unknown. This study aimed to assess upland cotton genotypes under salt priming and successive induced salt stress. Transcriptomic analysis revealed common differentially expressed genes (DEGs) enriched in pathways related to transferase activity, terpene synthase activity, lipid biosynthesis, and regulation of acquired resistance under salt priming, indicating the beneficial role of salt priming in enhancing salt stress resistance. Coexpression network analysis identified 16 hub genes involved in cell wall biogenesis, glucan metabolic processes, and ribosomal RNA binding. Overall, the findings provide insights into the regulation of candidate genes in response to salt stress and the beneficial effects of salt priming on enhancing defense responses in upland cotton.
