These stresses adversely affect its growth, productivity and survival by altering physiological functions, disturbing cellular homeostasis and triggering oxidative damage. In response, J. regia deploy a multifaceted adaptive system comprising morphological changes, biochemical adjustments and intricate molecular signaling pathways. The review aims to analyze current knowledge on the physiological, morphological changes observed under stress with biochemical defense mechanism. These include the crucial antioxidant defense system (increase in Superoxide Dismutase (SOD), Peroxidase (POD) and Catalase (CAT) activity), the accumulation of protective soluble solutes and amino acids and the biosynthesis of secondary metabolites through the Methylerythritol Phosphate (MEP) pathway involved in mitigating oxidative stress caused by Reactive Oxygen Species (ROS). Crucially, we synthesize the understanding of molecular regulation that underpins stress adaptation. This encompasses stress-responsive gene expression including Jr (Juglans regia) VHAG1 (V-ATPase H+ transporting ATPase subunit G1), JrDREB (Dehydration-Responsive Element Binding protein), JrRD29 (Responsive to Dehydration 29), transcriptional regulation by myeloblastosis (MYB), Dehydration-responsive element-binding proteins (DREB) and WRKY-TF families and their interaction with hormonal (abscisic acid (ABA), jasmonic acid (JA), salicylic acid (SA) and ethylene) which play a pivotal role in signal transduction and stress tolerance. These mechanisms employed by walnut under abiotic stresses, highlighting key genetic and hormonal pathways that can be targeted for the development of stress-resilient cultivars and ensuring sustainable production under changing climatic conditions. Recent advancements in genomics, transcriptomics and proteomics got attention that provides new insights into the regulatory networks and candidate genes conferring stress resilience. Furthermore, it explores biotechnological approaches for improving stress tolerance, highlighting the prospects of latest high-throughput techniques, including molecular breeding, genetic engineering, Next-Generation Sequencing (NGS), microRNA (miRNA)-based regulation and Clustered regularly interspaced short palindromic repeats and CRISPR-associated protein 9 (CRISPR/Cas) gene editing.

To address these challenges, it is crucial to associate the desired stress-responsive genes with specific stress-inducible promoters for developing plant varieties with broad-spectrum stress tolerance. In this study, the promoter region of the anthocyanidin synthase (ANS) gene from banana was thoroughly analysed, and its tissue-specific expression, in response to various environmental insults was delineated. Comprehensive analyses such as transcript abundance-based expression profiling and evaluation of ProANS-GUS activity in transgenic lines was performed and the expression patterns thus obtained were corroborated with the presence of corresponding cis-elements in the promoter region. Transcription of the ANS gene was strongly altered by the imposition of environmental stresses or signaling molecules. MusaANS transcripts in banana were significantly suppressed by exposure to high salinity, salicylic acid or abscisic acid, while its expression was stimulated by methyl jasmonate as well as drought. In P_MusaANS-GUS transformed tobacco lines, P_MusaANS activity was mainly observed in the vascular tissue under control conditions. Drought, salinity, MeJA, salicylic acid and ABA strongly activated P_MusaANS whereas, ethephon suppressed its activity. Thorough scrutiny of P_MusaANS showed the presence of a diverse array of stress and phytochemical response-associated cis-elements, such as ARR1AT (cytokinin), ACGTATERD1 (drought), DPBFCOREDCDC3 (ABA), ABREOSRAB21 (ABA), ASF1MOTIFCAMV (salicylic acid), ERELEE4 (ethylene) and BIHD1OS (pathogen response).

In this study, we examined the seed coat anatomy of six tropical plant species collected from southern Thailand using light microscopy, cell scanning electron microscopy and quantitative analyses.

Tubular sclereids were consistently located in the tegmen layer of Croton persimilis, Entada rheedei, Elateriospermum tapos, Ricinus communis, Hevea brasiliensis, and Jatropha curcas.

Melatonin has shown promising results in alleviating abiotic stress by inducing antioxidant defenses in several species, which is particularly interesting when considering medicinal plants. Thus, this study investigates the physiological and biochemical responses of Brazilian-ginseng (Pfaffia glomerata) to PEG 4000-induced osmotic stress and the mitigating effects of exogenous melatonin. Under osmotic stress, P. glomerata exhibited reduced growth, diminished photosynthetic pigments, and increased reactive oxygen species (ROS) levels, highlighting the detrimental impact of water deficit on plant health. Melatonin, in turn, differentially affected leaves and roots, failing to restore shoot growth while promoting root elongation under osmotic stress. In addition, melatonin increased the activity of antioxidant enzymes, particularly peroxidase (POD), reducing ROS production and membrane damage in the leaves. In roots, PEG only increased catalase (CAT) activity. Osmotic adjustment following melatonin application was also evident through elevated sucrose and proline levels, supporting cell turgor and stress adaptation. Interestingly, osmotic stress increased 20-hydroxyecdysone (20-E) levels in roots; however, this increase occurred independently of melatonin. Therefore, despite the induction of osmotic adjustments and antioxidant defenses, melatonin was unable to reverse the growth restraints caused by osmotic stress in P. glomerata. Furthermore, our findings reveal a complex interplay between osmotic stress, antioxidant defenses, and secondary metabolite production. The insights gained offer potential applications for improving stress resilience and secondary metabolite synthesis in medicinal plants, with implications for sustainable agriculture.</p>","PeriodicalId":20731,"journal":{"name":"Protoplasma","volume":" ","pages":"1397-1414"},"PeriodicalIF":2.7,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13275640/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147594122","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Optimizing the culture medium is essential for the success of embryo rescue, as it directly influences the development and germination of in vitro embryos. Therefore, this study systematically investigated the effects of parental genotypes and the addition of zeatin (ZT) to the culture medium on the efficiency of embryo rescue, using four self-pollinated maternal parents and 23 seedless×seeded (or seedless) cross combinations. The results showed that among the four self-pollinated parental lines, hybrid ovules exhibited the highest development rate in the ER medium, while a higher proportion of normal plantlets was obtained in the MM3 medium. Although the addition of ZT at various concentrations did not significantly enhance the embryo development rate in the self-pollinated maternal parents, it significantly improved germination outcomes: compared to the control, the rate of normal plantlet formation increased by 8.84-19.03%, while the proportions of abnormal plantlets and ungerminated embryos were significantly reduced. Further validation in hybrid combinations revealed that the addition of an appropriate concentration of ZT significantly increased both embryo development and plantlet formation rates in both MM3 and ER media. Specifically, in the MM3 medium supplemented with 0.5 mg L^-¹ ZT, the hybrid combination 'Huozhoucuiyu × Yan73' achieved the highest embryo development rate (63.33%) and plantlet formation rate (26.67%). Across the 23 hybrid combinations, the average embryo development rate reached 39.57%, yielding a total of 1,554 hybrid progeny.

An integrated tolerance matrix classified cultivars into four groups, identifying VL-2028 as the most tolerant, with superior photosynthesis, growth and antioxidant capacity coupled with minimal oxidative damage, whereas VL-953 was the most sensitive. Intermediate responses were recorded for moderately tolerant (VL-2015, VL-826, VL-1080) and moderately sensitive (VL-967, VL-907) cultivars, and these groupings were supported by heatmap based clustering. LTS reduced biomass, chlorophyll content, photochemical efficiency Fv/Fm, and ETR, while increasing proline accumulation, malondialdehydeand membrane leakage.
