Summary: This study reveals that the ATS1 gene negatively regulates salt resistance in Arabidopsis. Overexpression of ATS1 leads to decreased salt tolerance in terms of seed germination, biomass, chlorophyll content, pod development, and increased root/shoot ratio and anthocyanidin content. Mutations in the ATS1 gene result in higher levels of unsaturated fatty acids, which stabilize the plasma membrane under salt stress. The ats1 mutants also regulate ion homeostasis by upregulating K+ uptake and downregulating Na+ uptake genes.

Summary: The gene ATL12 plays an important role in the response to salt stress and abscisic acid (ABA) in Arabidopsis thaliana. Overexpression of ATL12 increases the expression of salt stress-associated genes and ABA-responsive genes, and leads to higher levels of reactive oxygen species. Mutants of atl12 are sensitive to salt stress and ABA, and have shorter root length. The findings suggest that ATL12 modulates the response to salt stress and is involved in the ABA signaling pathway.

Summary: This study investigated the transcriptomic responses to drought and high salinity in alfalfa using different germplasms with varying tolerances, revealing differential expression and post-transcriptional modifications. Additionally, the diversity of circRNA and lncRNA in response to these stresses were identified for the first time in alfalfa. The analysis also identified master genes and isoforms that may play crucial roles in drought and salt stress tolerance in alfalfa.

Summary: This study reveals the regulatory role of Small Paraquat resistance protein (SPQ) in the adaptation of higher plants to extreme environmental conditions. Overexpression of SPQ enhances resistance to paraquat and sensitivity to abscisic acid (ABA). Knockout mutant of SPQ1 shows slightly different responses to these substances. Moreover, overexpression of SPQ improves drought tolerance in plants.

Summary: Deinococcus radiodurans is an extremophile with remarkable stress tolerance against DNA-damaging agents like gamma rays, ultraviolet radiation, oxidation, and desiccation. Global regulators of this bacterium play a crucial role in responding to oxidative and desiccation stresses. The Late Embryogenesis Abundant proteins (LEAs) in D. radiodurans are essential for stabilizing metabolic enzymes and maintaining metal ion homeostasis under oxidative and desiccation conditions, showing potential for biotechnological and therapeutic applications.

Summary: AtPHB2 gene was cloned from Arabidopsis thaliana and localized in mitochondria, which was found to promote seed germination and plant growth under different stresses, and enhance resistance to saline-alkali and oxidative stresses. Transgenic plants overexpressing AtPHB2 showed higher K+/Na+ ratio and lower H2O2 content after 24 h of salt treatment, indicating its involvement in reducing reactive oxygen species (ROS) levels and improving plant tolerance to salt stresses.

Summary: This study investigates the molecular mechanisms of plant responses to salt stress in salt cress. Phenotypic analysis, transcriptomic and proteomic profiling, and other assays were conducted to validate the role of BRs in regulating plant responses to salt stress. The results indicate that BES1 plays a positive role in plant salt tolerance.

Summary: In apple, a key component of BR signaling, MdBIM1, increases cold tolerance by activating the expression of CBF genes and forming complexes with MdCBF2. The repressors of JA signaling, MdJAZ1 and MdJAZ2, interact with MdBIM1 to integrate BR and JA signaling under cold stress. The E3 ubiquitin ligase MdATL73 targets MdBIM1 for degradation, reducing cold tolerance. This study reveals the crosstalk between BR and JA signaling and provides insights into the posttranslational regulation of BR signaling.

Summary: This study revealed that arginine decarboxylase (ADC) functions as a positive regulator of melon seedling cold tolerance, with the transcription factors CmABF1 and CmCBF4 directly targeting ADC to trigger its expression. Additionally, other CBF and ABF members were also found to have functional redundancy and complementarity with CmABF1 and CmCBF4.

Summary: In this study, a heat shock transcription factor gene, HaHSFA1, was cloned from Haloxylon ammodendron and overexpressed in Arabidopsis thaliana to investigate its effects on salt tolerance. The results showed that overexpression of HaHSFA1 increased chlorophyll content, promoted plant growth, increased soluble sugar and proline contents, enhanced antioxidant activity, improved root activity, and increased selective absorption and transport capacity for K+ over Na+. These findings suggest that HaHSFA1 has potential application in improving crop abiotic stress tolerance through genetic engineering.

Summary: The plant-specific SCL30a SR protein negatively regulates ABA signaling to control seed traits and stress responses during germination in Arabidopsis. Loss of SCL30a function induces ABA-responsive gene expression and genes repressed during germination, resulting in delayed germination and hypersensitivity to ABA and high salinity in scl30a mutant seeds. Transgenic plants overexpressing SCL30a exhibit reduced ABA and salt stress sensitivity.

Summary: Salt stress is a major abiotic stress that limits plant survival and crop productivity. The Salt Tolerance-Related Protein (STRP) has been characterized as a protein involved in plant responses to cold stress and proposed as a mediator of salt stress response in Arabidopsis thaliana. This study investigated the role of STRP in salt stress responses and found that STRP plays a protective role by reducing oxidative stress and is involved in osmotic adjustment mechanisms in A. thaliana.

Summary: The study found that the geomagnetic field regulates the activity of the plasma membrane proton pump H+-ATPase, and reduced geomagnetic field values weaken the binding of 14-3-3 proteins to the pump, leading to decreased activity. This effect is associated with downregulation of genes related to ROS production, calcium homeostasis, and plant hormone synthesis, which ultimately result in inhibited root growth.
