Chilling injury poses a major challenge to global crop production, and the regulatory hierarchies that govern cold adaptation in polyploid crops are unexplored. Here, we show that tetraploid wucai (Brassica campestris L.) displays greater cold tolerance than its diploid counterpart. Under prolonged cold stress, tetraploid plants displayed enhanced glucosinolate-associated transcriptional and metabolic responses, which may contribute to their improved stress adaptation. At the epigenetic level, diploid and tetraploid wucai showed distinct DNA methylation responses to short-term cold, with diploid plants tending toward greater CHH hypermethylation in promoter regions. This ploidy-specific increase in methylation correlates with transcriptional repression of multiple stress-responsive loci in diploids. Notably, expression of the glucosinolate biosynthesis gene METHYLTHIOALKYLMALATE SYNTHASE1 (BcMAM1) diverged between ploidies after cold treatment, inversely correlating with opposing CHH methylation (H = A, C, or T) trends in its promoter. Pharmacological demethylation using 5-azacytidine upregulated BcMAM1 and improved cold tolerance. Through a combination of functional assays and promoter-binding analyses, we identify the upstream transcription factor C-REPEAT BINDING FACTOR4 (BcCBF4), which binds to differentially methylated regions within the BcMAM1 promoter in a methylation-sensitive manner, supporting an association between the epigenetic state and transcriptional output. Together, our findings support a mechanistic model for the distinct cold response observed in the autotetraploid wucai line, involving coordinated changes in transcriptional activation and DNA methylation dynamics. The epigenetic and transcriptional targets identified in this study may inform breeding strategies for cold-resilient crops.","PeriodicalId":20101,"journal":{"name":"Plant Physiology","volume":"13 1","pages":""},"PeriodicalIF":7.4,"publicationDate":"2026-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149221359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As they share the same biosynthetic pathway, anthocyanins are interlinked with phenylalanine-derived volatiles. However, involvement of the MBW complex in regulating these floral volatiles has not been demonstrated. TRV-based suppression of either AN1 or AN11 led to an increase in volatile emission, indicating that they are involved in negative regulation of this trait. Yeast two-hybrid and in-planta pairwise and three-way protein-interaction assays revealed that EMISSION OF BENZENOIDS V (EOBV) is a component of the MBW complex. Headspace and internal pool analyses of flowers from eobv-knockout lines, generated using a viral-based CRISPR/Cas9 system, revealed that EOBV fine-tunes volatile production: phenylpropenes and vanillin levels increased while those of benzenoids and phenylpropanoid-related compounds decreased. Accordingly, transcript levels of C4H2, directing carbon flux to phenylpropenes and vanillin production, and ADT3 were significantly elevated in eobv-knockout flowers, along with decreases in PAAS and BSMT. Moreover, in-planta promoter activity assays in petunia flowers further demonstrated that C4H2 is negatively transcriptionally regulated by EOBV. In addition to its involvement in volatile production, EOBV is heat-responsive and affects flower development under high-temperature conditions by mitigating the reduction in flower size. EOBV’s participation in the MBW complex that regulates volatiles and anthocyanins reveals an intriguing molecular link between these showy traits and flower development.","PeriodicalId":20101,"journal":{"name":"Plant Physiology","volume":"426 1","pages":""},"PeriodicalIF":7.4,"publicationDate":"2026-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149221421","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study reports TabZIP12, a wheat bZIP transcription factor, in regulating osmotic stress tolerance. Under drought and abscisic acid (ABA) treatment, TabZIP12 expression was significantly upregulated with a dose- and time-dependent manner. Y-2H, BiFC, Co-IP, and In vitro pull-down assays confirmed a physical interaction between TabZIP12 and the kinase TaSnRK2.6. This kinase further interacted with the phosphatase TaPP2C50, which in turn interacted with the ABA receptor TaPYL1. These interactions suggest the TabZIP12-involved constitution of a synergistic signaling module (TaPYL1–TaPP2C50–TaSnRK2.6–TabZIP12). Transgene analyses revealed the essential functions of the signaling module members. Of which, TaPYL1, TaSnRK2.6, and TabZIP12 positively while TaPP2C50 negatively regulated drought tolerance, due to their roles in modulating key physiological processes associated with stomatal movement, osmolyte biosynthesis, root morphology, ABA biosynthesis, and reactive oxygen species (ROS) scavenging. TabZIP12 possessed an ability in binding with the promoters of critical stress-responsive genes, namely SLAC1 gene TaSLAC1-4, P5CS gene TaP5CS1, PIN-FORMed gene TaPIN3, NCED gene TaNCED3, and APX gene TaAPX6 and activated their activation. Transgenic validation confirmed these genes in positively modulating drought adaptation. Notably, in a wheat variety panel sharing contrasting drought response, the transcripts of TabZIP12 and its target genes correlated significantly with plant dry matter and yield under drought conditions. Haplotype analysis identified TabZIP12-Hap1 as a favorable allele associated with enhanced drought tolerance. Our findings elucidate novel mechanisms underlying the bZIP-mediated drought response and provide valuable genetic resources for breeding drought-resistant wheat varieties.","PeriodicalId":20101,"journal":{"name":"Plant Physiology","volume":"8 1","pages":""},"PeriodicalIF":7.4,"publicationDate":"2026-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149221361","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among these, 8-oxo-7,8-dihydroguanine (8-oxodG) is particularly mutagenic because it exhibits ambiguous base pairing, as DNA polymerases efficiently incorporate adenine opposite 8-oxodG, leading to G·C→T·A transversions. Despite exposure to oxidative stress, plant organellar genomes exhibit some of the lowest nucleotide substitution rates in nature, implying that their DNA replication machinery may have evolved mechanisms to cope with oxidative lesions such as 8-oxodG. In family-A DNA polymerases, including yeast and animal mitochondrial DNA polymerases, the balance between faithful dCMP incorporation and mutagenic dAMP incorporation opposite 8-oxodG is governed by a bulky or positively charged residue. Surprisingly, although the equivalent position in the Arabidopsis thaliana organellar DNA polymerases AtPolIA and AtPolIB is occupied by glycine—a residue predicted to promote mutagenic dAMP incorporation—both enzymes nevertheless preferentially incorporate accurate dCMP opposite 8-oxodG. Our structure–function analyses demonstrate that AtPolI´s fidelity opposite 8-oxodG is conferred by a lysine located near the templating base, which generates steric and electrostatic constraints that favor the 8-oxodG(anti):dCTP pairing while disfavoring the mutagenic 8-oxodG(syn):dATP pair. This mechanism represents an example of convergent evolution, as the fidelity-determining lysine in plant organellar polymerases is in a different position than the analogous residues in yeast-animal mitochondrial polymerases but achieves the same function. Together, these findings suggest that plant organellar DNA polymerases have evolved specialized properties that promote accurate bypass of oxidative DNA lesions, which may contribute to the maintenance of the exceptionally low mutation rates observed in plant organellar genomes.","PeriodicalId":20101,"journal":{"name":"Plant Physiology","volume":"73 1","pages":""},"PeriodicalIF":7.4,"publicationDate":"2026-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149218632","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although miR397 is known to be involved in plant stress responses, its regulatory mechanism in grapevine salt tolerance remains unclear. In this study, we systematically deciphered the role of the VvmiPEP397-VvmiR397-VvLAC14 module in grapevine salt stress responses using transgenic approaches, transcriptome sequencing, and molecular biology techniques. Our results show that salt stress significantly induces VvMIR397 expression. We identified a functional small peptide, VvmiPEP397, from its primary transcript. Exogenous application of this peptide enhanced VvMIR397 expression and improved salt tolerance in grapevine calli and plants. Overexpression of VvmiR397 significantly enhanced salt tolerance in both grapevine and Arabidopsis, whereas silencing its expression increased sensitivity. Transcriptome analysis further identified the laccase gene VvLAC14 as a direct target of VvmiR397. VvmiR397 negatively regulates VvLAC14 expression through transcript cleavage, reducing lignin accumulation. Conversely, VvLAC14 overexpression increased lignin content and compromised salt tolerance, whereas knockdown of VvLAC14 had opposite effects. This study establishes, for the first time in grapevine, a complete regulatory pathway comprising a small peptide, miRNA, and target gene – VvmiPEP397-VvmiR397-VvLAC14 – revealing a novel mechanism by which this module influences salt tolerance through the regulation of lignin metabolism. Our findings provide new targets and a theoretical foundation for salt-tolerant grapevine breeding.","PeriodicalId":20101,"journal":{"name":"Plant Physiology","volume":"11 1","pages":""},"PeriodicalIF":7.4,"publicationDate":"2026-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149221422","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we targeted the conserved uORF that resides in the 5'-untranslated region (5'-UTR) of a GDP-galactose phosphorylase gene (GhGGP1) in cotton (Gossypium hirsutum). Regulation of GGP1 is a key control point of plant L-ascorbic acid biosynthesis. Using a dual-luciferase reporter system, we demonstrate that this uORF represses translation of the downstream GGP1 coding sequence in a feedback manner in response to elevated ascorbate, confirming previous findings in other species. Furthermore, CRISPR/Cas9-mediated disruption of the uORFGhGGP1 generated homozygous uorfGhGGP1 mutants with unchanged transcript levels but markedly increased protein abundance and L-ascorbic acid accumulation. Under drought stress, these mutants exhibit reduced malondialdehyde levels, enhanced total antioxidant capacity, and improved drought tolerance. Mechanistically, we further show that under drought conditions, the transcription factor GhBBM directly binds to the uORF-containing cis-regulatory element, enhancing (GhGGP1) transcription and drought resistance. Together, our findings establish the uORFGhGGP1 as a dual-layer regulatory module that integrates transcriptional activation by GhBBM with translational control of the downstream protein encoding open reading frame, thereby fine-tuning drought stress responses in cotton.","PeriodicalId":20101,"journal":{"name":"Plant Physiology","volume":"17 1","pages":""},"PeriodicalIF":7.4,"publicationDate":"2026-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149218630","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They can nonetheless rapidly initiate under-ice blooms at extreme low-light levels in early spring. The limits and mechanisms underlying this ability remain unknown. To explore the absolute minimum light required for photoautotrophic growth, we investigated the physiological and transcriptional state of the polar diatom Fragilariopsis cylindrus across a winter-to-spring light gradient. While cell division is arrested at 0.18 µmol photons m−2 s−1, photosynthetic electron transport remains operational down to 0.1 µmol photons m−2 s−1, which suggests an uncoupling between photosynthesis and biomass accumulation. Crucially, nondividing cells do not enter hypometabolism but instead maintain a functional photosynthetic metabolism without reserve consumption, redefining the lower limit of photoautotrophic life. While cells optimize photon capture efficiency between 3 and 15 µmol photons m−2 s−1 relative to 30 µmol photons m−2 s−1, this strategy collapses below 1 µmol photons m−2 s−1. In this dim-light regime, cells activate nonphotochemical quenching and a sustained xanthophyll cycle, which indicates a paradoxical requirement for energy dissipation. We propose that at these extremely low light levels, light absorption appears to exceed the minimum energy requirements for cell maintenance. To manage this active imbalance, cells dissipate excess energy as heat through active nonphotochemical quenching and possibly carbohydrate secretion, indicating a paradoxical requirement for energy dissipation despite extreme photon scarcity. This mechanism allows them to maintain a primed photosynthetic metabolism to facilitate rapid growth recovery upon the return of light after the winter solstice.","PeriodicalId":20101,"journal":{"name":"Plant Physiology","volume":"16 1","pages":""},"PeriodicalIF":7.4,"publicationDate":"2026-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149218631","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We extend the Update from ABA-relevant gene discovery to recent advances in multicellular coordination of stomatal control. Growing evidence supports the view that ABA-regulated stomatal movement and gas exchange are coordinated across multiple cell types, including guard cells, mesophyll cells, bundle sheath cells, and vascular tissues in roots and leaves. We also highlight emerging tools to dissect this ABA-mediated multicellular network by using emerging technologies in single-cell and spatial omics, plant optogenetics, and artificial intelligence (AI). These advances will shape ABA research from single cell models toward multicellular collaborative networks for understanding plant-environment interactions. Together, this article links the history of ABA research with emerging single-cell resolution datasets and AI-assisted computational approaches, proposing a framework for moving ABA biology from well-established guard-cell signaling models toward a broader understanding of multicellular ABA coordination.","PeriodicalId":20101,"journal":{"name":"Plant Physiology","volume":"13 1","pages":""},"PeriodicalIF":7.4,"publicationDate":"2026-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149221423","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although energy-dissipation mechanisms involving remodeling of photosystems are well known, the role of downstream metabolic routes in energy dissipation remains understudied. Here, we show that two metabolic nodes, glycogen phosphorylase (glgP) and phosphoenolpyruvate (PEP) synthase (pps), participate in photoprotection under high light in Synechococcus elongatus PCC 7942. Glycogen phosphorylase is important for photosystem I (PSI) protection under high or changing light conditions. Under high light, the ΔglgP mutant exhibits severe chlorosis and reduced cyclic electron flow (CEF), approximated from the P700+ re-reduction rate, without major changes in carbon metabolism. Comparative proteomics further suggests redox exchange from NADPH to NADH, consistent with a role of GlgP in maintaining P700 acceptor side oxidized via enhanced CEF. Meanwhile, PEP synthase acts as a key node regulating tricarboxylic acid (TCA) cycle flux and potentially NADPH production. Under high light, the Δpps mutant rewires its metabolism to enhance CEF, likely a compensatory mechanism that offsets excess NADPH from elevated TCA flux. Long-term maintenance of Δpps resulted in a spontaneous secondary deletion in adhE, encoding succinate semialdehyde dehydrogenase (SSADH) of the TCA bypass. This suppressor mutation, combined with the loss of PEP synthase, partially mitigates high-light stress at the cost of reduced amino acid synthesis. These findings reveal important roles for downstream carbon metabolism in high-light acclimation and provide new insights into photoprotective mechanisms in phototrophs.","PeriodicalId":20101,"journal":{"name":"Plant Physiology","volume":"31 1","pages":""},"PeriodicalIF":7.4,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149187913","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
