Summary: This study investigated the photosynthetic and physiological characteristics, chemical composition of wax and cutin monomers, and expression of cuticle-associated genes in the leaves of Thellungiella salsuginea under NaCl stress. The findings suggest that T. salsuginea has an adaptive response to salt stress, manifested by decreased photosynthetic rate and stomatal conductance, increased water use efficiency, and an increase in total wax content.

Summary: By resequencing the whole genomes of natural populations of Eutrema salsugineum across its Asian and North American distributions, selection signals for genes involved in salt and other abiotic tolerance were detected at the species level. Additionally, local adaptation in North America-NE Russia and northern China led to selection signals in cold-induced and defense genes. These variations provide valuable insights for understanding the genetic mechanisms underlying stress tolerance and local adaptations in this model species.

Summary: The understanding of the molecular basis of abiotic stresses, such as salt, cold, and drought, is crucial for developing breeding and genetic engineering strategies in sugarcane. This study investigated the plant's responses to these stresses, including chlorosis, wilting, leaf rolling, and changes in water content. The results also showed an accumulation of LPO and an increase in proline content, indicating the plant's stress responses. Additionally, differential gene expression analysis revealed the involvement of various stress-responsive genes in sugarcane seedlings, providing insights into the molecular basis of stress response in this important crop.

Summary: The AP2/ERF gene family is a conserved and important transcription factor family mainly found in plants, with various functions in regulating plant biological and physiological processes. This study focused on the AP2/ERF gene family in Rhododendron simsii, an important ornamental plant, using the existing whole-genome sequence of Rhododendron to investigate the genes on a genome-wide scale. A total of 120 Rhododendron AP2/ERF genes were identified and classified into five main subfamilies. The study also analyzed the expression patterns of these genes and found that they responded to abiotic stresses. This research provides comprehensive information on the AP2/ERF gene family in Rhododendron and lays the foundation for future genetic improvement.

Summary: Salt cress display relatively high phosphate use efficiency in its natural habitat, with Phosphate Transporters playing critical roles in phosphate acquisition and homeostasis. Comparative study of PHT families between salt cress and Arabidopsis revealed more gene copies and divergent transcriptional regulation in salt cress, contributing to its adaptation to salinity and phosphate limitation.

Summary: The study identified and characterized the GST gene family in the halotolerant cyanobacterium Halothece sp. PCC7418. One of the GSTs, H3557, showed significant upregulation under salt stress and exhibited GST activity towards CDNB and GSH with a broad range of enzymatic activity. This salt-adaptive enzyme remained catalytically active in the presence of NaCl and conferred tolerance to H2O2-induced oxidative stress and salt stress in heterologous expression systems.

Summary: This research aims to explore salt resistance genes and their physiological modifications in tall wheatgrass ecotypes. The results show that resistant ecotypes exhibit higher gene expression levels and antioxidant activity, leading to better growth under salinity condition. NHX1, NHX2, and HKT1;4 genes play important roles in salt resistance.

Summary: bZIP transcription factors play important regulatory roles in plant growth and stress responses. The study classified 132 bZIP genes in the tobacco genome into 11 groups and identified segmental duplications as crucial for gene family expansion. Expression analysis showed differential expression of NtbZIP genes in various tissues and stresses, with NtbZIP62 responding strongly to salinity stress and enhancing salt tolerance when overexpressed. This research provides valuable insights for future functional analyses of bZIP genes in tobacco.

Summary: This study characterized 37 VrDIR genes in mungbean and found that they have different gene structures and expression patterns, responding differently to salt and drought stresses. The VrDIR genes showed distinct distribution on the 11 mungbean chromosomes and were classified into five groups based on phylogenetic relationships, with 13 duplicated gene pairs identified. Additionally, a total of 92 cis-acting elements were detected in all 37 VrDIR promoter regions, indicating potential regulatory roles of these genes in response to environmental stresses.

Summary: This study identified and classified 14 PYR/PYL genes, 9 PP2C (A) genes, and 10 SnRK2 genes from the halophytic plant Eutrema. The phylogenetic analysis and gene structure analysis supported the existence of 4 EsPYR/PYL, 4 EsPP2C (A), and 3 EsSnRK2 subfamilies. Furthermore, it was demonstrated that a large-scale segmental duplication event played a major role in the expansion of these gene families. Comparative synteny analysis revealed more orthologous gene pairs between Eutrema and Brassica than between Eutrema and Arabidopsis. RNA-seq and qRT-PCR experiments confirmed the up-regulated expression of several genes in response to ABA, NaCl, or cold stress. Additionally, WGCNA analysis uncovered several co-expression modules containing the PYL-PP2C (A)-SnRK2 genes, providing new insights into their potential molecular functions.

Summary: This study highlights the role of salt priming in mitigating salt stress on faba bean. It was found that salt shock resulted in negative effects on growth, photosynthetic pigments, and yield, accompanied by increased generation of H2O2 and lipid peroxidation. However, priming with increasing concentrations of NaCl improved plant defense mechanisms, including enhanced expression of GSH-related genes, proline accumulation, and antioxidant enzymes, thereby reducing the detrimental effects of salt shock on growth and yield.
