When dark-germinated plants are exposed to the light, etioplasts differentiate into chloroplasts, converting protochlorophyllide (Pchlide) into chlorophyll, while excessive free Pchlide accumulation in etioplasts causes reactive oxygen species (ROS) generation and cell death under light conditions. Despite this knowledge, the molecular mechanisms by which dark-germinated plants adapt to the light environment via transcriptional regulation of chlorophyll biosynthesis remain unclear. We previously identified BRZ-INSENSITIVE-PALE GREEN 4 (BPG4) as a light-inducible chloroplast homeostasis factor. Here, we identified the BPG4 paralog BPG4 HOMOLOGOUS GENE 2 (BGH2) as a nucleus-localized plastid regulator required for light adaptation in Arabidopsis thaliana. Dark-inducible BGH2 interacts with GOLDEN2-LIKE 1 (GLK1) and GLK2, master transcription factors regulating chlorophyll biosynthesis. This interaction suppresses excessive photosynthesis-associated nuclear gene (PhANG) expression, avoids Pchlide overaccumulation in the dark, prevents ROS generation, and promotes healthy cotyledon greening during de-etiolation. BPG4 and BGH2 expression is regulated by GLK and PHYTOCHROME-INTERACTING FACTOR transcription factors under light and dark conditions. Overall, our findings suggest that BGH2 plays an essential role in fine-tuning chlorophyll biosynthesis and etioplast homeostasis by inhibiting GLK transcriptional activity and excessive PhANG expression in the dark.","PeriodicalId":501012,"journal":{"name":"The Plant Cell","volume":"11 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144684239","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While senescence induces large-scale metabolomic changes, the characterization of metabolic shifts and the identification of key metabolites and pathways determining the staygreen trait remain limited. Here, we generated a temporal map of the physiological and metabolic variation in genetically diverse maize (Zea mays) inbred lines spanning the staygreen spectrum. Integrated analysis of the captured phenotypic variation revealed substantial metabolic perturbations and identified 42 primary and 141 specialized leaf metabolites. Non-staygreen inbred lines were enriched in primary metabolites represented by sugar alcohols (notably mannitol and erythritol), and amino acids including phenylalanine and arginine. In contrast, the staygreen inbred lines accumulated higher levels of specialized metabolites, primarily phenylpropanoids. Metabolome-to-genome mapping identified 56 candidate genes expressed in adult maize leaves responsible for the metabolic changes that occur during senescence. Reverse genetics validated the role of naringenin chalcone and eriodictyol in maize and Arabidopsis thaliana leaf senescence, demonstrating a conserved function of these flavonoids across monocots and dicots. Together, our results reveal the coordinated physiological and metabolic programs that govern senescence and provide a curated set of metabolites and genes underlying this complex process.","PeriodicalId":501012,"journal":{"name":"The Plant Cell","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144684445","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Analysis of AtGELP53-overexpressing independent transgenic lines revealed a decrease in xyloglucan acetylation, changes in acetylation of other polysaccharides, and alterations in cell wall composition. Molecular docking and in vitro protein activity assays showed that AtGELP53 might deacetylate xyloglucan and xylan. Elicitor-based, transcriptomic, and proteomic analyses in AtGELP53-overexpressing lines suggested that oligosaccharide-mediated signaling activates the cell wall and defense-related genes primarily through xyloglucan deacetylation. Furthermore, AtGELP53-overexpressing plants showed resistance against Pseudomonas syringae and Ralstonia solanacearum through activation of elicitor-mediated defense responses.

The phytohormone jasmonate regulates Arabidopsis thaliana seed size, but the underlying molecular mechanisms remain elusive. Here, we established that CORONATINE INSENSITIVE1 (COI1)-mediated jasmonate signaling acts maternally to repress seed growth. Accordingly, jasmonate signaling suppresses the expression of KLUH (KLU), encoding an inducer of integument cell proliferation. KLU regulates the effects of COI1-mediated signaling on seed size. The JASMONATE ZIM-DOMAIN (JAZ) repressors of jasmonate signaling interact with SUPPRESSOR OF DA1-1 (SOD7) and DEVELOPMENT-RELATED PcG TARGET IN THE APEX4 (DPA4), two transcription factors that directly repress KLU. Overexpression of SOD7 largely rescues the seed size phenotype of coi1 mutants and JAZ1-overexpressing JAZ1-ΔJas plants. Furthermore, SOD7 associates with MYC2 and MYC4, two master transcriptional regulators of jasmonate signaling. SOD7 and MYC2 synergistically decrease KLU transcription and inhibit seed growth, while JAZ1 interferes with their transcriptional activities and physical interaction. Notably, jasmonate signaling considerably impacts seed size under salinity stress, primarily through SOD7 and KLU. Collectively, our findings suggest that the JAZ repressors and MYC transcription factors of the jasmonate signaling pathway coordinate with the SOD7/DPA4-KLU pathway to incorporate jasmonate signals into seed development.","PeriodicalId":501012,"journal":{"name":"The Plant Cell","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144652864","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Plant-pathogen interactions activate endogenous plant-secreted peptides, which act as immunity inducers and are promising breeding targets for enhancing crop resistance to pathogens. However, the identification and mechanisms of immunogenic peptides in staple crops remain largely unexplored. Here, we demonstrated that plant elicitor peptides (TaPeps) in wheat (Triticum aestivum), processed by a metacaspase, are competent to trigger plant immunity and contribute to resistance against Fusarium head blight (FHB). Using exogenous phytocytokine peptide screens, we identified three potential TaPeps acting as elicitors that significantly improve FHB resistance. Mechanistically, these elicitors activate innate immune signals and calcium dynamics in response to the Fusarium pathogen via wheat PEP RECEPTOR 1 (TaPEPR1). Overexpression of endogenous PRECURSOR OF PEPs (TaPROPEPs) further reduces FHB severity. Moreover, we characterized the natural form of TaPeps in planta, revealing that the wheat type-II metacaspase TaMCA-IIa cleaves TaPROPEPs at a conserved arginine residue, promoting TaPep maturation and immune activation. In Tamca-IIa mutants, the efficiency of TaPep maturation was decreased and calcium dynamics were impaired, resulting in FHB susceptibility. Conversely, overexpressing TaMCA-IIa in wheat enhanced the immune response and FHB resistance without causing pleiotropic growth penalties. Our findings highlight TaPeps as potential immune-inducing biologicals for crop protection and uncover the metacaspase-Peps-receptor module in mediating plant disease resistance.","PeriodicalId":501012,"journal":{"name":"The Plant Cell","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144652857","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Whereas excluding bZIP2, bZIP11 and bZIP44 to play a major role in DIS, bZIP1 and bZIP53 act partially redundantly to control a co-expression network governing amino acid catabolism and transport, gluconeogenesis and energy homeostasis. Moreover, bZIP1 and bZIP53 regulate genes involved in the asparagine–glutamine balance, two amino acids critical for carbon and nitrogen homeostasis. This transcriptional reprogramming in resource management is required for survival during starvation and regaining meristematic activity during the recovery from stress. Thus, our findings provide insights into the transcriptional control of plant resource and energy management during starvation.

Fruit bloom, an off-white substance covering the fruit surface and affecting its appearance, is crucial for the market-driven breeding and production of cucumbers (Cucumis sativus). However, the mechanisms regulating fruit bloom formation are not well understood. In this study, we aimed to elucidate the molecular mechanisms underlying silicon deposition in glandular trichomes (GTs) and GT’s role in fruit bloom formation. Using map-based cloning, we identified a single-nucleotide polymorphism in CsaV3_3G017280, encoding a homolog of the rice (Oryza sativa) silicon efflux transporter Low Silicon Rice 2 (Lsi2), causing a premature translation termination mutation linked to the non-fruit-bloom phenotype. Knocking out CsLsi2 prevented silicon deposition on the fruit surface, leading to a non-fruit-bloom phenotype. The MYB transcription factor CsRAX3 directly activated CsLsi2, and the GT development–related factor TINY BRANCHED HAIR (TBH) regulated both CsRAX3 and CsLsi2, linking silicon deposition with GT development.
