Metal toxicity diminished growth, chlorophyll, and antioxidant pigments, alongside a profound diminution in relative water content. Conversely, metal toxicity initiates a surge in the accumulation of amino acids, soluble sugars, proline, and glycine betaine, which indicates osmotic adjustment in plants. Metal toxicity diminished nitrate reductase activity, elevated reactive oxygen species (ROS) generation, and heightened oxidative injury. In stressed plants, enhanced lipoxygenase (LOX) activity exacerbated membrane lipid peroxidation. Antioxidant enzyme activities decreased while the levels of flavonoids, phenolics, reduced glutathione (GSH) and oxidized glutathione (GSSG) increased, accompanied by a reduction in the GSH:GSSG ratio. Plants experienced impaired nutrient acquisition under metal toxicity. Coumarin and hesperidin increased nitric oxide and hydrogen sulfide levels, which might have restored the redox balance. Consequently, plants administered coumarin and hesperidin manifested more profound levels of chlorophyll, strengthened antioxidant system, efficient ROS detoxification, and diminished oxidative damage that, in turn, restored cellular homeostasis. Coumarin and hesperidin remarkably ebbed aerial translocation of metals, thereby preventing colossal metal accumulation in leaves.</div></div>","PeriodicalId":34736,"journal":{"name":"Plant Stress","volume":"16 ","pages":"Article 100818"},"PeriodicalIF":6.8,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143688031","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}

This study investigates the physiological, transcriptomic, and metabolomic responses of <em>Nicotiana tabacum</em> to varying levels of drought stress (well-watered, light drought, moderate drought, and severe drought). Comprehensive analyses were conducted to evaluate phenotypic changes, physiological parameters, gene expression, and metabolite profiles. Drought stress significantly inhibited plant growth, reduced relative water content, and altered transpiration rates. Protective enzyme activities also declined under increased drought intensity.

Plants counteract these stresses through intricate genetic and biochemical pathways, which are largely mediated by signalling networks that involve key transcription factors (TFs). Among these, WRKY TFs are crucial in modulating plant responses to various stresses. In previous studies, WRKY TFs have been identified in millets. However, their functional characterization in millets remains vastly unexplored. Therefore, we have isolated and characterized <em>PgWRKY52</em>, a Group IIc WRKY TFs from pearl millet, along with its upstream promoter region to understand its functional regulatory role. Ectopic expression of <em>PgWRKY52</em> in transgenic Arabidopsis improved seed germination under salt stress and phytohormonal treatments of abscisic acid (ABA) and methyl jasmonate (MeJA). Improved stress tolerance was linked to reduced reactive oxygen species (ROS) accumulation and upregulation of stress-responsive genes, indicating an enhanced defense system. Promoter analysis unveiled that the <em>PgWRKY52</em> promoter was constitutively active across vegetative and reproductive tissues, with strong stress-inducible activity under salt, heat, and ABA treatments. Cis-regulatory element (CRE) analysis identified key stress-responsive elements, including ABRE, MYB, W-box and MYC, which were validated through mutational studies as essential for promoter activity. Additionally, <em>PgWRKY52</em> exhibited W-box-dependent DNA-binding capability, a characteristic feature of WRKY TFs. These findings emphasize the important function of the <em>PgWRKY52</em> promoter in driving stress-responsive transcription.

The ability of plants to propagate acquired epigenetic changes through cell division indicates their potential role in long term adaptation to changing environmental conditions. The key role in this process is the interaction between cytosine methylation, histone modifications and RdDM. The main target for cytosine methylation are the transposon elements (TEs). Stress induced differential methylation of TEs can induce <em>cis</em>- and <em>trans-</em> regulation of gene activity as well as their mutagenic potential. TE insertion however, does not happen completely at random, but is dependent on the histones present in the chromatin structure of a particular genomic region. Recent experiments show strong evidence for preferential stress induced TE activation and insertion as a force in short and long term adaptation. Additional evidence exists for unique activation of TEs during meiosis, enhancing the probabilities for unique beneficial mutations in the progeny. Plants have evolved different responses for many types of stress and depending on the severity, duration and repetitiveness of the stress can induce different types of epigenetic changes. Drought, nutrients, salinity, temperature and various types of biotic stresses have their own cytosine methylation profile. This data highlights the potential existence of a strong internal mechanism for stress induced transgenerational adaptation, which can be harnessed for developing stress-resilient crops.</div></div>","PeriodicalId":34736,"journal":{"name":"Plant Stress","volume":"16 ","pages":"Article 100812"},"PeriodicalIF":6.8,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143684497","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}

Field experiments were conducted growing spinach plants subjected to cultivation with 1 mg/L CdS NPs contamination, with foliar application of SiO<sub>2</sub> NPs at concentrations of 1, 20, and 100 mg/L. The phenotypic, biochemical, and metabolic responses of the plants to stress conditions were examined following exposure to CdS and SiO<sub>2</sub> for four weeks. The results showed that SiO<sub>2</sub> NPs increased the fresh and dry weights of both roots and shoots. Furthermore, CdS NPs exposure reduced chlorophyll content by 66.76 %, whereas SiO₂ NPs co-exposure increased chlorophyll levels by up to 42 % compared to the CdS NPs and control groups. However, elevated malondialdehyde (MDA) levels were observed in leaves for the CdS-only group and roots for all treatments indicating oxidative stress was most pronounced for the CdS case. Results demonstrated that SiO₂ application significantly reduced Cd accumulation in spinach by up to 34.92 %. Also, enhanced mineral accumulations were recorded in both roots and shoots, whereas decreased levels were found in the co-exposure groups, except for Zn. The exposure to SiO<sub>2</sub> resulted in upregulation of metabolites including galactonic acid, d-aspartic acid and others, and UDP-d-galactose was downregulated in the group exposed only to CdS NPs. The upregulation of these metabolites by SiO<sub>2</sub> NPs demonstrates their mitigating effect against CdS NPs induced stress. This work enhances understanding of phenotypic and metabolic alterations induced in spinach by CdS and SiO<sub>2</sub> NPs, and independently and through their co-exposure. Overall, our findings indicate that Cd contamination can be reduced in spinach using SiO<sub>2</sub> NPs when applied at low levels, and the mechanisms are discussed.</div></div>","PeriodicalId":34736,"journal":{"name":"Plant Stress","volume":"16 ","pages":"Article 100811"},"PeriodicalIF":6.8,"publicationDate":"2025-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143683970","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}

In this work, an untargeted metabolomics approach (UHPLC/QTOF-MS) was used to unveil the metabolic shifts in leaves and spikes of two cultivars of winter wheat, treated either with systemic agrochemicals (Syst; i.e., prochloraz and tetraconazole) or a BCA (<em>Trichoderma gamsii</em> T6085), and subsequently inoculated with a spore suspension of <em>Fusarium graminearum</em> and <em>F. langsethiae</em>.

Supervised modeling (OPLS-DA) highlighted distinct metabolic differences between the cultivars, FHB infection, and treatment conditions.
