Gamma aminobutyric acid (GABA) is an important signaling molecule involved in plant stress adaptation, but its role in regulating sulfur metabolism and antioxidant defense under aluminum stress remains poorly understood. This study investigated the impact of foliar application of GABA (100 μmol L^-1) on aluminum tolerance in <i>Camelina sativa</i> exposed to Al stress (50 mg kg^-1 soil Al) using controlled experiments and naturally aluminum-contaminated mining soil. GABA application significantly improved plant performance by increasing plant height, biomass, root growth, photosynthetic pigments, and gas exchange parameters compared with Al-stressed plants. In addition, GABA enhanced antioxidant protection by increasing the activities of ascorbate peroxidase, catalase, peroxidase, and superoxide dismutase, while reducing reactive oxygen species accumulation and the malondialdehyde content by improving the redox balance. GABA treatment increased glutathione levels and the GSH/GSSG ratio, whereas the accumulation of oxidized glutathione and dehydroascorbic acid induced by aluminum stress decreased, indicating improved antioxidant recycling capacity. Furthermore, GABA restored sulfur metabolism by regulating cysteine, glucosinolate, glutathione S-transferase activity, and the expression of sulfur-related genes, including <i>ST5a b c</i>, <i>CYP83A1</i>, and <i>BCAT4</i>. Functional inhibitor experiments demonstrated that the protective role of GABA depends on calcium signaling and reactive oxygen species signaling pathways. Transcriptome analysis further revealed extensive regulation of genes involved in antioxidant defense and sulfur metabolism. These findings demonstrate that GABA enhances aluminum tolerance through coordinated regulation of sulfur metabolism, redox homeostasis, and stress signaling, providing new insights into sustainable strategies for improving crop resilience in aluminum-affected soils.</p>","PeriodicalId":94172,"journal":{"name":"Plant signaling & behavior","volume":"21 1","pages":"2705725"},"PeriodicalIF":3.6,"publicationDate":"2026-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13393235/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148551957","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Silicon, a beneficial element, has shown potential in mitigating various abiotic stresses. However, although numerous studies have been conducted in this field, the precise mechanism by which exogenous silicon mitigates salt stress in tomato seedlings remains to be fully elucidated. In this study, we analyzed the physiological responses and underlying molecular mechanisms in tomato seedlings under NaCl stress with or without silicon application. The results showed that salt stress severely inhibited seedling growth, as indicated by reductions in shoot and root fresh weight and plant height, while this damage was markedly alleviated by the application of exogenous silicon. Compared to the treatment with NaCl alone (Na), salt stress plus silicon treatment (Na + Si) improved plant growth, the leaf chlorophyll a content, the net photosynthetic rate (Pn), and the proline content and decreased the contents of reactive oxygen species (ROS) and malondialdehyde (MDA) in tomato seedlings. Transcriptomic analysis showed that there were 435 differentially expressed genes (DEGs) (397 upregulated and 38 downregulated) between Na + Si and Na treatments. Further enrichment analysis showed that the upregulated DEGs in Na + Si treatment were enriched in response to salt stress, ethylene and abscisic acid biosynthesis process, lignin catabolic process, cell wall biogenesis and the MAPK signaling pathway. Additionally, exogenous silicon application (Na + Si) upregulated the expression of key families of transcription factors, notably the AP2/ERF, WRKY and NAC families.

These studies have majorly focused on how plants respond to an individual stress at a particular point in time. But in nature, no stress occurs in isolation; rather, they act mostly in combination.

Through this review, we have made an attempt to decipher the physiological and molecular responses of different plant species to multiple stress combinations.

H1 stabilizes the nucleosome structure and promotes higher-order chromatin compaction. It interacts with chromatin modifiers to influence nucleosome accessibility, thereby regulating transcriptional events. H1 variants exhibit distinct spatiotemporal expression patterns and play key roles in stress adaptation. Under abiotic stress, the depletion of H1 is associated with dynamic DNA demethylation at transposable elements and altered histone marks.

Our study revealed that BFA treatment induces the formation of BFA bodies containing PIN2-GFP and GFP-LTi6a in epidermal cells, with the earliest and most pronounced accumulation occurring in the transition zone, though it is also observable in the meristematic zone. In contrast, such accumulation are virtually undetectable for PIN3-GFP and GFP-LTi6a in columella cells. Similar effects were observed when BFA was replaced with Lat B, suggesting that the absence of these proteins' accumulation may be more closely connected to distinct intracellular vesicular transport mechanisms inherent to columella cells, rather than unconventional secretion pathways. Further analysis shows that Lat B treatment led to significant aggregation of key endomembrane organelles in epidermal cells, including the Golgi apparatus, trans-Golgi network (TGN), recycling endosomes (RE), early endosomes (EE), and late endosomes (LE). In contrast, columella cells displayed slight aggregation, limited to the Golgi apparatus, TGN, and RE, without obvious aggregation of EE or LE.
