To address this, we investigated the variation and the genetic basis of mineral content, including, among others, calcium, iron, phosphorus, and zinc, in a diverse panel of maize (Zea mays L.) grown across environments. Our results show that genetic variation significantly contributes to differences in mineral content. Genotype-by-environment interaction and environmental factors, such as reduced phosphorus fertilisation, substantially impact the ionome composition, particularly decreasing zinc content and altering grain quality. Correlations between the 12 minerals were mostly positive, with variation observed in mineral composition between tissues and in translocation from vegetative to generative tissue. In addition, elite lines exhibited distinct mineral profiles compared to landraces. Genome-wide association mapping revealed a quantitative inheritance of the minerals and few common quantitative trait loci. Significantly associated markers were found in proximity to candidate genes involved in processes like mineral transport, detoxification and storage, which represent potential targets for marker-assisted selection to improve nutritional quality in maize. In conclusion, our results highlight the temporal and spatial dynamics of the maize ionome as a basis toward its targeted design for future agriculture.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.3,"publicationDate":"2025-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144991139","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 aimed to establish a framework (isolate-select-construct) for tailoring simplified salt-tolerant synthetic microbial communities (SynComs) and explore how they confer salt stress resistance to the plant. First, a total of 512 strains were isolated from the high-salt rhizosphere soil of Populus euphratica through high-throughput cultivation. Among these, nine strains were further selected for their salt-tolerant and growth-promoting abilities, with three isolates identified as key microbes, including hub microbes, keystone taxa and biomarkers. Guided by a function-driven strategy, we constructed five distinct SynComs, with SynCom5, SynCom7 and SynCom9 showing the most significant improvement in the growth of hybrid Poplar 84K (Populus alba × Populus glandulosa). Mechanistic investigations revealed that these SynComs can increase resistance to salt stress by directly reducing oxidative stress, adjusting osmolytes and balancing ions. Additionally, these SynComs were observed to recruit specific root-associated bacterial consortia that enhance the adaptability of poplar to salt stress. Overall, this study lays the groundwork for designing SynComs that promote plant growth and offers insights into harnessing specific microbial communities to boost plants' salt resistance.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.3,"publicationDate":"2025-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144991089","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}

Maize drought tolerance mechanisms were evaluated in a 20-year experiment with low, medium, and high crop diversity rotations using soil zymography to visualize enzyme activity distribution and high-throughput sequencing to assess microbial communities. High crop diversity increased maize shoot biomass by 56%-87% and reduced drought-induced root biomass loss by 14%-59% compared to low crop diversity. Root diameter increased by 1.7-2.5 times leading to better drought tolerance by 2.2-2.7 times, and stabile key rhizosphere microbiota. The complexity of the rhizosphere bacterial network increased with crop diversification, and the keystone taxa (such as biofilm-producing Pseudomonas ) raised maize drought tolerance by increasing rhizosphere water retention. These microbiota increased habitat resilience under drought, increasing ecosystem provision and regulatory functions. Activities and hotspot areas of enzymes related to carbon and nitrogen cycling decreased with crop diversification, but changed minimally under drought, indicating that this enzymatic resilience could contribute to maize drought tolerance. In conclusion, crop diversification enriches drought-tolerance microbial species in soil that stabilize the rhizosphere microenvironment and facilitate root proliferation, underscoring the importance of crop-microbial interactions for drought resilience.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.3,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144937570","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}

The advent of high-throughput sequencing has accelerated the discovery of novel viruses in cultivated and wild rice, unveiling previously undetected threats. This review systematically summarises newly discovered rice viruses over the past decade, analyzing their genomic characteristics, transmission modes, and pathogenic mechanisms. Key findings include the identification of rice stripe mosaic virus, rice tiller inhibition virus (RTIV), RTIV2 and rice curl dwarf-associated virus, among others, highlighting their interactions with host immunity and insect vectors. Notably, emerging viruses exhibit novel infection strategies, including interference with RNA silencing, hormone signalling, and autophagy pathways. Moreover, mixed infections and cross-species transmission raise concerns about evolving disease dynamics. Understanding these viral threats is crucial for developing integrated disease management strategies, including resistant cultivars and vector control measures. This review provides a comprehensive resource for advancing rice virology research and guiding future efforts in monitoring and mitigating viral diseases affecting global rice production.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.3,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144937542","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}

The molecular mechanisms by which plants coordinate responses to these two stresses deserve more attention. Here, we explored how StSOBIR1, a leucine-rich repeat receptor-like kinase gene, modulates plant responses to herbivory and high temperature stress using genetic, molecular, biological, and chemical analysis approaches. StSOBIR1 encodes a plasma membrane-localized protein and its expression is rapidly induced upon herbivore attack. StSOBIR1 negatively regulates jasmonic acid (JA) signaling and JA-mediated defenses, thereby hindering herbivore resistance to potato tuber moth (Phthorimaea operculella) at a normal temperature (22°C). In contrast, the transcripts of StSOBIR1 were suppressed by high temperature (32°C). StSOBIR1 positively regulates plant responses to high temperature stress, including the accumulation of sucrose, proline and chlorophylls. Moreover, at high temperature, both the StSOBIR1-knock down and overexpression plants exhibited similar JA signaling and herbivore resistance to wild-type plants. Transcriptome analysis revealed that high temperature interferes with StSOBIR1-mediated defensive responses to herbivory by disrupting herbivory-associated gene co-expression networks and reprioritizing its functions. Taken together, these results show that StSOBIR1-mediated fine-tune plant responses to herbivory and high temperature, while under combined stresses, its negative regulatory function over herbivore defense is lost.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.3,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144937522","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 an important miRNA family, the role of MIR444 in the root development of rice remains largely unknown. Here, we observed that loss of miR444f, which belongs to the MIR444 family, exhibited significant developmental defects in primary and lateral roots during early growth stages. Cellular and molecular analyses revealed that miR444f affected growth activity, cell division, and elongation in the root apical meristem. This effect was mediated through its targeting of the MADS-box transcription factors OsMADS27 and OsMADS57, which are key regulators of the gibberellin (GA) metabolic pathway. Subsequently, the expression of GA metabolic genes and GA accumulation were significantly altered. Furthermore, exogenous GA restores root growth defects in miR444f mutants, confirming the central role of the GA signalling pathway in miR444f-regulated root growth. These findings offer strategic insights for optimizing crop root architecture and function through genetic engineering, aimed at enhancing productivity and environmental resilience.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.3,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144937564","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 investigates the potential of non-adapted interaction triggered by Paracidovorax avenae (Pa), a maize pathogen, to combat BFB in watermelon. We demonstrate that Pa strain ATCC 19860 elicits a hypersensitive response (HR) in watermelon via its type III secretion system (T3SS), inducing effector-triggered immunity (ETI). To rapidly screen for Pa type III effectors (T3Es) related to ETI, the nonpathogenic Pseudomonas fluorescens Effector-to-Host Analyzer (EtHAn) strain was used for transient expression of T3Es in watermelon. Among 13 candidate T3Es, the acetyltransferase AopP2 emerged as a potent inducer of programmed cell death (PCD) in watermelon, dependent on its enzymatic activity. AopP2 suppresses reactive oxygen species (ROS) bursts, salicylic acid (SA) signalling, while stabilizing the transcription factor ClTFIIB2 via acetylation, thereby activating ETI. Silencing ClTFIIB2 compromised both basal resistance to Pc and AopP2-induced PCD, whereas transient ClTFIIB2 expression via the EtHAn system enhanced resistance to Pc and AopP2-induced PCD. Notably, pretreatment with low-dose AopP2 primed watermelon defences, significantly reducing Pc proliferation. This study demonstrates that AopP2 suppresses pattern-triggered immunity (PTI) via CITFIIB2 acetylation while triggering ETI, revealing a conserved immune node exploitable for engineering resistance in watermelon. Our findings highlight the potential of non-adapted pathogen effectors as tools for activating ETI to identify disease resistance genes, and provide the first evidence of ClTFIIB2's critical role in watermelon immunity, offering novel strategies for BFB management.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.3,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144937579","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}
