However, the molecular mechanisms underlying its cold tolerance remain unclear. In this study, an integrated approach combining physiological analysis and multi-omics techniques was employed to investigate the metabolic pathways and molecular mechanisms involved in the cold stress response of P. veitchii. Metabolomic analysis revealed significant changes in the levels of 61 metabolites under cold stress, with prominent increases in polyamines (e.g., p-Coumaroylputrescine, +2.97-fold) and phenolic acids (e.g., Syringic acid, +3.69-fold). Transcriptomic profiling identified 22,525 DEGs, including 3852 genes enriched in cold adaptation pathways including plant hormone signaling, MAPK signaling, and glutathione metabolism. Key regulators of polyamine and phenolic acid metabolism were identified, including aldehyde dehydrogenase, arginine decarboxylase, polyamine oxidase (PAO), S-adenosylmethionine decarboxylase, and aspartate aminotransferase, with downregulation of PAO, promoting salidroside accumulation but simultaneously suppressing methylated indole-3-acetic acid. Moreover, the reduced accumulation of flavonoids may be linked to the expression of flavonoid 3'-monooxygenase. Furthermore, it was discovered that the ETH, JA-Ile, SA, and MAPK signaling pathways play an active role in the signaling of P. veitchii roots during the response to cold stress. This study offers valuable insights into the complex regulatory mechanisms that govern the cold stress response in P. veitchii roots, thereby establishing a theoretical basis for a better understanding of its response and adaptation mechanisms to cold stress.</p>","PeriodicalId":20164,"journal":{"name":"Physiologia plantarum","volume":"177 4","pages":"e70400"},"PeriodicalIF":5.4,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144576114","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}

Our study focuses on a novel seed-preferential C<sub>2</sub>H<sub>2</sub> zinc finger transcription factor, ZOS5-09 (LOC_Os05g38600) that plays an important role in regulating rice grain traits. Rice plants with the ZOS5-09 promoter::GUS construct showed high expression of ZOS5-09 in rice endosperm. In planta reporter effector assays and localization studies showed that ZOS5-09 is a nuclear-localized transcriptional repressor. It has two C<sub>2</sub>H<sub>2</sub> zinc finger domains and a C-terminal NoRS (nucleolar retention signal). Ectopic and seed-preferential overexpression of ZOS5-09 resulted in lethality. Seed-preferential overexpression without NoRS was detrimental to grain filling. Rice plants with knock-down or CRISPR-based knock-out of ZOS5-09 displayed reduced grain length and weight but increased grain width. Grain size change was due to lower cell proliferation and increased cell size in the transverse direction because of downregulation of cell cycle-related genes and increased expression of expansins. Decreased expression of ZOS5-09 also resulted in reduced total starch and protein content and higher endosperm chalkiness, thus negatively affecting grain quality. ZOS5-09 directly bound to a zinc finger-binding site and regulated a seed storage protein-encoding gene, GLU6. It acted as a repressor by promoting deacetylation upon interaction with a histone deacetylase.

This study investigates the effects of cerium oxide nanoparticles (CeO<sub>2</sub>-NPs) on growth, photosynthetic properties, antioxidant enzyme activities, and aroma synthesis in fragrant rice seedlings under Cd stress. Heavy metal contamination in agriculture, particularly cadmium, is exacerbated by its high mobility. Nanotechnology, particularly the application of cerium oxide nanoparticles (CeO<sub>2</sub>-NPs), presents a significant yet underexplored potential for mitigating these detrimental effects. Our results demonstrate that CeO<sub>2</sub>-NPs significantly enhance the tolerance of fragrant rice seedlings to Cd stress. This is achieved primarily by reducing Cd uptake and suppressing the expression of genes responsible for Cd uptake and translocation. CeO<sub>2</sub>-NPs also improve the antioxidant capacity of the seedlings, alleviate the impairment of the photosynthetic system under Cd stress, and promote root and overall plant growth. Additionally, CeO<sub>2</sub>-NPs increase the aroma content of fragrant rice by enhancing the activity of aroma-related enzymes, increasing proline content, and subsequently elevating the levels of 2-acetyl-1-pyrroline (2-AP), a key aromatic compound. The study underscores the dual role of CeO<sub>2</sub>-NPs in mitigating Cd toxicity and enhancing aromatic quality in fragrant rice.
