An association panel of 171 rice genotypes was evaluated for physiological and yield-related traits, including the cumulative response index, under both normal planting density (NPD) and low planting density (LPD) conditions. LPD, serving as a proxy for elevated atmospheric [CO2], significantly increased all trait values, except for harvest index, compared to NPD. A genome-wide association study identified 172 QTNs, including 12 associated with multiple traits under NPD or LPD conditions. Candidate gene mining and network analysis within QTN regions identified potential candidates such as OsHAK1, RGA1, OsalphaCA3, OsalphaCA4, OsalphaCA5, OsCYP38, and OsPIN1, influencing various physiological and yield-related traits under LPD conditions. A significant relationship between the percentage of favorable alleles in genotypes and their performance under different conditions was observed. Potential haplotypes were validated using genotypes identified with contrasting [CO2] responses, grown under LPD and Free-Air [CO2] Enrichment facility. These findings can aid in selectively breeding genotypes with favorable alleles or haplotypes to enhance [CO2] responsiveness in rice. Incorporating greater phenotypic plasticity can help develop climate-smart rice varieties that increase grain yield and quality while mitigating losses from warming temperatures.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143661862","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 show that grass Brachypodium distachyon derives some nitrogen from amino acids in uninfected Pseudomonas putida necromass lysed by sonication but not from virocell necromass. Additionally, the bacterial necromass elicits the formation of rhizosphere exometabolites, some of which (guanosine), alongside tested aromatic acids (p-coumaric and benzoic acid), show bacterium-specific effects on bacteriophage-induced lysis when tested in vitro.

Shoots grow vertically, while stolons grow horizontally underground and produce tubers at their tips. However, transcriptional differences between shoot and stolon cells remain unclear. To address this, we performed single-cell RNA sequencing of the shoot apex and stolon tip, generating a comprehensive transcriptional landscape. We identified 23 distinct cell clusters with high cell heterogeneity, including cell-specific genes and conserved genes with cell-specific expression patterns. Hormone-related genes, particularly those involved in auxin and gibberellin pathways, exhibited distinct patterns among shoot and stolon cells. Meristematic cells were re-clustered based on the expression of StPOTH15, a homolog of SHOOT MERISTEMLESS (STM) in Arabidopsis. Co-expression networks of transcription factors identified the key transcription factors involved in stolon development. We also constructed developmental trajectories for xylem and phloem development using key vascular genes, including MP, XCP1, PP2A1 and SEOR1. Comparative analysis with Arabidopsis highlighted significant differences in cell type-specific transcript profiles. These results provide insights into the transcriptional divergence between potato shoot and stolon, and identify key transcription factors co-expressed with StPOTH15 that can be used to explore their roles in stolon development.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143646707","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}

Novel host pine Pinus tabuliformis is inherently unsuitable for invasive red turpentine beetle (RTB) in China; however, Novosphingobium and Erwinia/Serratia in gallery microbiota (at the interface between RTB larvae and pine phloem) have been discovered to help beetles via biodegrading pine detrimental compounds naringenin and pinitol, respectively. Here, we further revealed significant positive linkage of the two functions, with higher activity level conferring more growth benefit to RTB larvae. Abundance of Erwinia/Serratia was remarkably increased in response to pinitol, while naringenin-biodegrading Novosphingobium was unable to utilize this main phloem carbohydrate directly. High-activity bacterial microbiota produced nutritive metabolites (sucrose and hexadecanoic acid) from pinitol consumption that facilitated growth of both Novosphingobium and beetle larvae. Functional proteins of several bacterial taxa were enriched in high-activity microbiota that appeared to form a metabolic network collectively to regulate the nutrient production. Our results indicate that positive interaction between Erwinia/Serratia and Novosphingobium is critical for RTB invasion success, while Bacilli bacteria might restrict this linkage, providing new insights into symbiotic microbial interactions for insect herbivores.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143646720","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}

Under mineral deficient conditions, plants rely on a sophisticated network of signalling pathways to coordinate their molecular, physiological, and morphological responses. Recent research has shown that long-distance signalling pathways play a pivotal role in maintaining mineral homeostasis and optimising growth. This review explores the intricate mechanisms of long-distance signalling under mineral deficiencies, emphasising its importance as a communication network between roots and shoots. Through the vascular tissues, plants transport an array of signalling molecules, including phytohormones, small RNAs, proteins, small peptides, and mobile mRNAs, to mediate systemic responses. Vascular tissues, particularly companion cells, are critical hubs for sensing and relaying mineral deficiency signals, leading to rapid changes in mineral uptake and optimised root morphology. We highlight the roles of key signalling molecules in regulating mineral acquisition and stress adaptation. Advances in molecular tools, including TRAP-Seq, heterografting, and single-cell RNA sequencing, have recently unveiled novel aspects of long-distance signalling and its regulatory components. These insights underscore the essential role of vascular-mediated communication in enabling plants to navigate heterogeneous mineral distribution environments and suggest new avenues for improving crop resilience and mineral use efficiency.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143646714","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 examines the ecophysiology of N2O reducers in the plant phyllosphere. Anoxic microcosm experiments, quantification of N2O reduction kinetics, and analysis of nosZ gene governing N2O reduction were conducted to assess the activity and presence of N2O reducers in leaf epiphytes from various canopy positions of Photinia fraseri, an urban greenery plant. Results revealed canopy position-dependent N2O reduction activity in the leaf microbiota. We identified previously unrecognised atypical Clade II nosZ gene in the phyllosphere microbiome, with its absolute abundance positively correlated with N2O reduction activity, highlighting its significance in this process. Sequencing of bacterial and archaeal 16S rRNA genes revealed keystone taxa as primary drivers of N2O reduction activity. These findings underscore the functional potential for N2O reduction and the presence of the Clade II nosZ group within epiphytic microbes. This work provides insights into the ecophysiology of epiphytic N2O reducers and underpins the development of leaf-based microbial solutions for N2O mitigation under future warming.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143623056","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}

Co-expression network analysis revealed that trigonelline accumulation, linked to the nicotinic acid and nicotinamide metabolic pathways, was significantly higher in clubroot-susceptible plants. Furthermore, applying trigonelline externally aggravated clubroot in both B. rapa and Arabidopsis thaliana. Overexpression of the nicotinate N-methyltransferase gene (BrNANMT) responsible for the conversion from nicotinate to trigonelline in these plants increased disease susceptibility, while loss of this gene's function resulted in improved clubroot resistance. Our study is the first to reveal the function of trigonelline in promoting clubroot development and identify BrNANMT as a clubroot susceptibility gene and trigonelline can be used as a marker metabolite in response to P. brassicae infection.

Limited research exists on how nutrient competition influences soil organic carbon (SOC) dynamics via modifying rhizosphere C turnover. To address this issue, quantitative model of plant-plant interactions was established in three intercropping systems across 4 years. Key variables, including plant growth rate, relative interaction intensity, C retention, root and microbial-driven C emissions, rhizosphere priming effects (RPE), and extracellular enzyme activities, were quantified. Superior species exhibited significantly higher growth rate, photosynthetic fixed C retained in roots and rhizodeposition, and root respiration, but lower RPE (31.9%) relative to monocultures. Such trend was tightly associated with significant reduction of microbial mineralization caused by rhizosphere nitrogen and phosphorus enrichment. In contrast, due to low nitrogen and phosphorus availability in rhizosphere soils, the activities of rhizosphere extracellular hydrolase of inferior species increased, resulting in significant increase in RPE (21.9%) and decrease in photosynthetic fixed C from rhizodeposition. Therefore, plant-plant interactions are crucial in regulating SOC turnover in rhizosphere soils, and superior species can enhance soil C conservation by increasing root C inputs and suppressing RPE. These findings confirm the role of plant-plant interactions in SOC turnover in dryland intercropping systems.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143603014","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}
