In this study, we demonstrate that cytokine receptor Domeless (Dome) in leafhopper Recilia dorsalis directly recognises glycoprotein (G) of an important rice rhabdovirus. This binding induces Dome dimerisation, which initiates JAK/STAT pathway and leads to STAT-dependent expression of antiviral immune effector in R. dorsalis (RdIE1). RdIE1 suppresses viral replication by inhibiting the RNA-binding activity of viral large polymerase (L). Dome residue T659 is essential for G recognition and L residues E774 and D775 are required for RdIE1 target. Notably, virus-encoded phosphoprotein competitively inhibits the phosphorylation of STAT by casein kinase II (CK2β), thereby abrogating STAT-dependent transactivation of target genes. Our findings redefine Dome as a viral sensor and reveal a biphasic strategy that balances antiviral immunity with persistent viral infection in insect vectors.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.3,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145129684","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 assessed the impact of elevated CO2 concentration (eCO2, 1000 vs. 400 ppm) on two genotypes of common bean (Phaseolus vulgaris L.), one susceptible and one resistant, infected with bean pod mottle virus (BPMV, Comovirus siliquae). For both genotypes, we found that plant growth, development and physiology were not enhanced under eCO2 enrichment in healthy plants, at the stage of BPMV inoculation. Under eCO2, the number of primary infection sites was reduced in both genotypes. Consistently, viral titre in inoculated leaves was lower, suggesting an enhanced resistance to BPMV in both genotypes under eCO2. To investigate the underlying mechanisms, we studied the expression of genes involved in different antiviral immune pathways: salicylic acid (SA)-signalling, RNA silencing and PAMP-triggered immunity (PTI) pathways. Under our experimental conditions, eCO2 neither primed the SA-signalling pathway nor the PTI pathway, in both genotypes. However, eCO2 seems to prime the RNA silencing pathway in the resistant genotype, and to a lesser extent, in the susceptible genotype.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.3,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145129763","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}

Despite increasing knowledge of the benefits of neighbour-relatedness in intraspecific interactions, little is known about chemically and microbially mediated kinship responses in cultivar mixtures. Using a series of field and controlled experiments that used two sets of rice cultivars of varying genetic relatedness, we demonstrated that increased yield in rice cultivar mixtures was mediated by a root signaling chemical and soil microbes in a relatedness-dependent manner. Focal rice cultivars could discriminate closely from distantly related cultivars responded by altering root behavior, biomass allocation, and flowering time, improving grain yield. Relatedness discrimination was accompanied by an alteration in root signaling (-)-loliolide and, subsequently, the soil microbial community. Furthermore, (-)-loliolide directly modified soil microbes that were related to flowering time and seed biomass. Therefore, neighbor relatedness shapes soil microbial communities, generating kinship effects in rice cultivar mixtures. In particular, root signaling (-)-loliolide levels and soil microbial responses generated improvement of grain yield in closely related rice cultivar mixtures. The findings not only yield critical insights into plant-neighbor and plant-soil interactions but also raise an intriguing possibility to increase crop production by manipulating kinship in cultivar mixtures.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.3,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145129712","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}

These two parameters can be derived from the widely-used Laisk method as the intercept of linear regression lines fitted to net assimilation rates (Anet) vs. chloroplast CO2 partial pressures (Cc) obtained at different low-irradiance levels. However, photosynthetic theory indicates curvature in the Anet-Cc relationship which conflicts with the use of linear relationships for analysis. We, therefore, systematically evaluated the limitations of the use of linear relationships across temperatures from 5°C to 40°C and quantified the sensitivity of errors in Γ* and DL estimates to the selected Cc range. We found that wide CO2 ranges, especially when they exclude the expected Γ*, can introduce substantial biases in parameter estimation with linear regressions, particularly at lower temperatures. This can lead to marked underestimates of Γ*, and biologically unrealistic DL. We propose refining the Laisk method by using a photosynthesis model to analyse data. The model better represents the nonlinear Anet-Cc relationship and yields consistent Γ* and DL estimates, regardless of the CO2 range used.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.3,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145129729","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}

Recently, there is a growing focus on enhancing K+-use efficiency (KUE) to ensure optimal plant growth, especially in K+ deficient soils. Most approaches are centred on targeting genes associated with K+ sensing, signalling and other pathways related to plant hormones. However, despite progress, the success stories for generating high KUE crops are still limited. In view of this, the present review highlights the role of hormonal signalling in regulating K+ deficiency-induced responses in plants. We integrate shreds of evidence of how these K+-hormone signalling crosstalk modulate root-system architecture, K⁺ uptake and stress resilience. Furthermore, a meta-analysis-based assessment of different hormones highlighted the central role of jasmonic acid and abscisic acid in mediating K⁺ deficiency-induced changes at the transcriptional level. The present review offers novel insights into K+-hormone crosstalk that can be used as a framework for advancing KUE research and addressing challenges towards global food security.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.3,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145079071","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}

To study the role of DNA methylation in salt-alkali tolerance, we conducted integrated whole-genome methylome and transcriptome analyses using two alfalfa cultivars with contrasting tolerance. Results showed that global methylation levels were only mildly affected by salt-alkali treatment, while a substantial number of differentially methylated regions emerged in the CHH context, particularly in promoter regions. Notably, the salt-alkali tolerant cultivar exhibited consistently lower CHH methylation in promoter regions than the sensitive cultivar, under both control and salt-alkali stress. Enrichment analysis showed that genes overlapping CHH-DMRs were associated with oxidoreductase activity. Five representative candidate genes-NCED, LOX2, LOX4, CuAO1 and CuAO2-were selected for validation. qRT-PCR and McrBC-PCR assays demonstrated that reduced promoter methylation was closely linked to stress-induced transcriptional activation. To test whether reduced DNA methylation contributes to tolerance, alfalfa seedlings were treated with 5-azacytidine, which enhanced antioxidant capacity under salt-alkali stress and supported a role for DNA demethylation in adaptation. Overall, this study highlights the importance of epigenetic regulation in forage adaptation to stress and provides a theoretical basis for future functional studies and molecular breeding.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.3,"publicationDate":"2025-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145079122","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}

Lettuce plants were grown in a climate chamber at two levels of PAR (200 and 400 μmol m-2 s-1, red/blue light), and at each PAR level there were also treatments with 25% of PAR or FR added. In all six treatments, response curves of leaf net photosynthesis rate (Pn) to different intensities of PAR or PAR + FR were determined. Adding FR to PAR increased Pn, but this was only 39%-64% of the increase seen under additional PAR, due to lower absorption of FR than PAR. Absorbed PAR and FR photons had similar photosynthetic efficiency. Leaves grown under FR showed acclimatory responses, such as reduced photosynthetic capacity and pigmentation, but the instantaneous photosynthesis response to FR was unaffected. FR had strong positive effects on growth: Partly substituting PAR by FR increased the radiation use efficiency of growth even when expressed per unit of absorbed radiation.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.3,"publicationDate":"2025-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145074275","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 evaluated the agro-physiological, symbiotic and microbial traits of two Moroccan winter chickpea (Cicer arietinum) varieties (Arifi and Bochra) under low-P conditions represented by three rock-P levels (0, 25, 50 and 75 kg P₂O₅ ha-1) and co-inoculation with Mesorhizobium ciceri and Rhanella aceri (PSB). Results showed that inoculation at rock-P levels ≥ 50 kg P₂O₅ ha-1, significantly improved symbiotic traits, plant biomass and nutrient uptake in both varieties, with Bochra exhibiting superior performance. At 75 kg P₂O₅ ha-1 of rock-P, Bochra exhibited a strong correlation between root morphological traits and P-related rhizosphere traits. Results further highlighted Bochra's robust response to inoculation under 75 kg P₂O₅ ha-1 rock-P, driven by its ability to shape the rhizobacterial community composition, where Mesorhizobium dominated and significantly influenced plant and rhizosphere traits. More notably in Bochra than Arifi, rhizobacterial species richness and community composition correlated strongly with nodule traits, plant traits and rhizosphere P-related parameters. These findings elucidate the significant contribution of the rhizosphere bacterial community to the symbiotic performance of Mesorhizobium-inoculated chickpea, which remains both genotype- and P-dependent.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.3,"publicationDate":"2025-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145074230","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}
