Transcriptome sequencing and non-targeted metabolomics methods were used to analyze the dynamic changes in differentially expressed genes and differentially accumulated metabolites, respectively, during storage at 8 ℃ or room temperature (15 ℃). The results indicated that anthocyanin and citrate contents in fruit were higher at 8 ℃ than at other storage temperatures. The mRNA levels of TT8, a bHLH transcription factor, were higher in fruits stored at 8 ℃ than at room temperature throughout the entire storage period. Conversely, alternative splicing transcripts of TT8△, lacking a partial coding sequence, exhibited lower expression levels in fruit stored at 8 ℃. During postharvest storage, the genes involved in flavonoid biosynthesis and proton pumping were activated by TT8 and its partners. So that the increasing anthocyanin contents in juice sac tissues were attributed partially to TT8 expression changes caused by the alternative splicing during postharvest storage at a moderate temperature.</p>","PeriodicalId":20064,"journal":{"name":"Plant Molecular Biology","volume":"115 6","pages":"122"},"PeriodicalIF":3.8,"publicationDate":"2025-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145346620","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These stressors drastically reduce crop yields, necessitating innovative solutions. Recent advancements in omics-based research-spanning genomics, metabolomics, proteomics, transcriptomics, epigenomics, and phenomics-have transformed our understanding of plant stress responses at the molecular level. High-throughput sequencing, mass spectrometry, and computational biology have facilitated the identification of stress-responsive genes, proteins, and metabolites critical for enhancing plant resilience. This review evaluates omics-driven strategies for improving crop performance under environmental stress. It emphasizes multi-omics data integration, precision breeding, artificial intelligence (AI) in crop modeling, and genome-editing technologies. Notably, breakthroughs in machine learning and AI have refined predictive modeling, enabling precise selection of stress-tolerant traits and optimizing breeding strategies. Despite these advancements, challenges remain, including the complexity of multi-omics data analysis, high technology costs, and regulatory barriers. Bridging the gap between research and practical applications requires developing cost-effective platforms, enhancing AI-driven models, and conducting large-scale field validations.

Salinization is a process when soil is tainted with salt that consequently impacts the growth and development of plants, which leads to a decline in the yield of many food crops. The present study provides a brief impression about salinity stress on physiological and molecular processes, which affects the plants' growth and development. Salinity stress in crop plants is responsible for various metabolic and physiological changes. In this study we summarize the genes and molecular mechanism involved in ion transport like Sodium/hydrogen antiporter exchanger (NHXs), High-affinity potassium transporters (HKTs) and osmolytes that causes nutritional disturbance and inhibits the process of uptake of water by roots, seed germination, photosynthesis, and declines the growth of plants. Salinity in wheat inhibits the spike development and yield potential of crop plants, lower yield production is particularly related to a decrease in tiller numbers and by sterile spikelets in some cultivars. Future studies should focus on crop tolerance to salinity to gain better understanding of crop tolerance in saline field conditions. Global cereal production is hampered by soil salinity and sodicity, but tolerance breeding has also been sluggish. Narrow gene pools, an overemphasis on the sodium exclusion mechanism, a lack of awareness against stress tissue tolerance mechanisms in which aggregation of inorganic ions such as Na<sup>+</sup> is involved, and the lack of appropriate screening tools, which leads to slowed development. This review summarizes current knowledge and emphasizes the need for integrative strategies to enhance wheat resilience under saline conditions.</p>","PeriodicalId":20064,"journal":{"name":"Plant Molecular Biology","volume":"115 6","pages":"121"},"PeriodicalIF":3.8,"publicationDate":"2025-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145346583","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Agropyron mongolicum possesses a wide range of drought tolerance genes acquired during its long evolution and adaptation to harsh environments. However, the regulatory mechanisms for drought resistance in A. mongolicum are complex, limiting the development and utilization of gene resources in response to drought stress. In this study, we examined differences in morphological, physiological, metabolite and transcript levels between the drought-tolerant (T) and drought-sensitive (S) genotypes of A. mongolicum to identify key metabolites and genes associated with the drought response. The morphological and physiological results suggest that the S genotype is suppressed by drought stress to a greater extent than the T genotype. Based on the metabolome and transcriptome data, we identified that serine/threonine-protein kinase SRK2 (SRK2), peptide chain release factor subunit 1 (eRF1), glutamine synthetase (GS), polyphenol oxidase (PPO), and aspartyl protease family protein (ASP) were highly correlated with key metabolites such as L-γ-glutamyl-L-leucine and γ-glutamylphenylalanine in leaves by co-expression network analysis, and alcohol-forming fatty acyl-CoA reductase (FAR), DNA oxidative demethylase (ALKBH), GDSL esterase/lipase (GELP), beta-fructofuranosidase (INV), and glutamine synthetase (GS) were highly correlated with key metabolites such as Trp-Glu-Ile and citric acid diglucoside in roots. Moreover, we identified the potential involvement of fatty acid degradation and glycolysis/glucogenesis pathways in the enhancement of drought tolerance in A. mongolicum.

To further understand the mechanism of action of BPH1 in ABA signaling, the putative binding partners of BPH1 were investigated. Arabidopsis stress associated protein 9 (AtSAP9), which acts as a positive regulator of ABA signaling, has been identified as a BPH1-binding protein. Both BPH1 and AtSAP9 proteins were localized in the nucleus and cytosol, and a direct interaction between BPH1 and AtSAP9 was confirmed using yeast two-hybrid and bimolecular fluorescence complementation assays. The cell-free degradation assay indicated that MBP-AtSAP9 protein was degraded more slowly when incubated with the bph1 extracts than with Col-0 extracts, and that its degradation was dependent on the presence of the proteasome inhibitor MG132. Negative regulation of AtSAP9 protein stability by BPH1 was also confirmed in planta. Despite the E3 ubiquitin ligase activity of AtSAP9, the protein level of BPH1 was unaffected by AtSAP9. Collectively, these results indicate that BPH1, a CRL3 substrate receptor, functions as a repressor of ABA signaling, potentially through ubiquitin-proteasome system-dependent degradation of AtSAP9.</p>","PeriodicalId":20064,"journal":{"name":"Plant Molecular Biology","volume":"115 6","pages":"117"},"PeriodicalIF":3.8,"publicationDate":"2025-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145329788","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
