Summary: The study shows that GVA diethyl ether can completely suppress the propagation of electrical signals from damaged leaves to neighboring systemic leaves in Arabidopsis thaliana, preventing the accumulation of jasmonates and JA-responsive genes in systemic leaves. However, local damaged leaves still respond to damaging stimuli, indicating that the cellular response is selectively blocked in systemic leaves.

Summary: Phosphatidic acid signaling and alternative splicing play a crucial role in inhibiting the ligand-dependent interaction of Class II acyl-CoA-binding proteins with lipoxygenase, triggering oxylipin signaling in salt-stressed soybean. The discovery highlights a dual mechanism that initiates the onset of oxylipin signaling in response to salinity.

Summary: High salinity causes stresses to plants, with the antioxidant enzyme Catalase2 (CAT2) playing a crucial role. The phytohormone jasmonic acid (JA) impairs plant salt stress tolerance by repressing CAT2 expression in an MYC2-dependent manner, leading to increased hydrogen peroxide accumulation and compromised salt stress tolerance. The study reveals that JA impairs Arabidopsis seedling salt stress tolerance through MYC2-mediated repression of CAT2 expression.

Summary: The study found that PLD alpha 1 plays a crucial role in Arabidopsis plants' response to high-magnesium stress, delaying leaf senescence. Knockout mutants of PLD alpha 1 exhibited premature leaf aging and disrupted homeostasis of essential nutrients such as magnesium, potassium, and phosphate under high-Mg2+ conditions. Additionally, high Mg2+ levels led to increased starch and proline content in Arabidopsis plants, with significantly different levels observed in the PLD alpha 1 mutant compared to wild type plants.

Summary: Research found that high potassium concentration in the growth medium leads to salinity stress in plants. Comparing Arabidopsis and its extremophyte relative Schrenkiella parvula, it was discovered that S. parvula can limit excess potassium accumulation while sustaining growth, by promoting nitrogen uptake and assimilation. On the other hand, Arabidopsis showed growth limitations due to poor balance between stress signaling, increased reactive oxygen species levels, and reduced photosynthesis. The ability to regulate nutrient uptake and coordinate transcriptomic responses are crucial for plants to survive high potassium-induced salinity stress.

Summary: Alkaline salinity constrains crop yield. Arabidopsis thaliana shows local adaptation to saline-siliceous and non-saline carbonate soils, but no natural population is found on saline-alkaline soils. This study suggests that tolerance to saline-siliceous soils may not confer tolerance to alkaline salinity.

Summary: The analysis of drought-related genes in cassava reveals the involvement of MeSPL9 in drought stress tolerance, with overexpression of a dominant-negative form of this gene showing negative roles in drought stress resistance. MeSPL9 expression is strongly repressed by drought treatment. Overexpression of rMeSPL9-SRDX in cassava conferred drought tolerance without affecting overall growth, leading to increased osmoprotectants and JA levels. This study suggests that MeSPL9 affects drought resistance by modulating protectant metabolite levels and JA signaling pathways, providing implications for engineering drought tolerant crops.

Summary: Melatonin is a multifunctional bioregulator in both mammals and plants. This study investigated the effect of melatonin on the resistance of wheat and rye seedlings to high temperature and the functioning of cellular protection systems. The results showed that melatonin treatment reduced the inhibition of growth caused by high temperature in wheat seedlings, while it had a smaller effect on rye seedlings. Melatonin treatment also prevented oxidative stress in both wheat and rye seedlings under high temperature conditions.

Summary: Extreme temperatures, especially in recent decades, have had a significant impact on plants and are one of the most dangerous abiotic stress factors. This review analyzes the latest information on the mechanisms by which plant cells receive signals of hyperthermia, including the role of membrane fluidization, changes in calcium channels, and increased generation of reactive oxygen species. The significance of gasotransmitters (NO, H2S) and their interactions with other mediators in transmitting heat stress signals to the cell nucleus is separately summarized. The role of key transcription factors (HSF, MBF, NAC, and WRKY) in plant adaptation to high temperatures is analyzed. Modern ideas on the activation and functioning of the main protective systems that provide plant resistance to hyperthermia, such as heat shock protein synthesis, antioxidant and osmoprotective systems, are summarized. Examples of genetic improvement of heat resistance in plants through gene transformation in the control of these systems are given.

Summary: This review examines the signaling and regulatory networks activated by plant cells in response to stress, including plant hormones and various non-hormonal mediators. The focus is on the functional linkages between jasmonic acid and jasmonate signaling components with gasotransmitters and other signaling mediators, as well as stress metabolites, in the regulation of plant adaptive responses to abiotic stressors. The involvement of NO, H2S, and CO in jasmonic acid formation and signal transduction in plant cells is discussed, along with the potential role of protein components in stress-protective effects of gasotransmitters. The importance of the functional interaction between jasmonic acid and signaling mediators in regulating antioxidant systems, stomatal apparatus, and other processes crucial for plant adaptation to abiotic stresses is emphasized.
