Here, 454 ELIPs genes from 15 species (chlorophytes to angiosperms) were analysed using phylogenomics, cis-regulatory element mapping, transcriptomics, and transgenic validation. Phylogenetics classified ELIPs into four groups: Group 1 exclusive to non-seed plants (e.g., Physcomitrium patens), while angiosperms retained only Groups II-IV, reflecting lineage-specific evolutionary trajectories. Gene family expansion in angiosperms primarily occurred via whole-genome duplication, while bryophytes expanded through dispersed/tandem duplication, indicating distinct ecological adaptation strategies. Promoter analysis revealed bryophyte ELIPs uniquely enriched with ABA-responsive (ABRE) and drought-inducible (MBS) motifs, suggesting cis-regulatory innovation for water stress. Dehydration-rehydration transcriptomics revealed transient upregulation of eight P. patens ELIPs during dehydration, contrasting with the sustained AtELIP2 induction in Arabidopsis thaliana. Transgenic Arabidopsis overexpressing PpELIP1/9 exhibited enhanced drought tolerance, delayed chlorophyll degradation, increased lateral root proliferation under ABA treatment, and reduced oxidative damages via chloroplast-localised thylakoid stabilisation. Our results highlight the conserved role of ELIPs in photoprotection and their functional diversification in ABA-mediated drought adaptation, positioning bryophytes as reservoirs of ancestral stress resilience, bridging 450 million years of ELIP evolution and proposing a molecular framework for engineering stress-resilient crops through ELIP manipulation.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.3,"publicationDate":"2025-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144758817","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}

Ectopic expression of Gs5PTase8, an inositol polyphosphate 5-phosphatase cloned from wild soybean (Glycine soja), significantly enhanced salt tolerance in cultivated soybean (Glycine max). In this follow up study, the overexpression of Gs5PTase8 was shown to improve salt tolerance in transgenic Arabidopsis thaliana, soybean hairy roots and composite plants, by preventing sodium (Na+) accumulation and maintaining lower sodium/potassium (Na+/K+) ratios in plants under salt stress. Additionally, the interactions between Gs5PTase8 and its substrate, inositol 1,4,5-trisphosphate (IP3), were investigated for their role in enhancing salt tolerance. Overexpressing Gs5PTase8 reduced IP3 contents, probably due to its 5-phosphatase activity. Moreover, external supplementation of IP3 could restore the Na+ accumulation in the Gs5PTase8-overexpressing tobacco BY-2 cells experiencing salt stress. The proteomic data obtained by data-independent acquisition implied that the degradation of IP3 or phosphatidylinositol 4,5-bisphosphate (PI(4,5)P2) by Gs5PTase8 may maintain the ion homoeostasis of plants under salt stress by influencing the cytosolic calcium (Ca2+) signalling and the salt overly sensitive pathways.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.3,"publicationDate":"2025-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144740762","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}

Large numbers of effectors secreted by phytoparasitic nematodes are delivered into host cells to facilitate susceptible invasion and maintain long-lasting parasitism in the host plants. Plant nucleotide-bound leucine-rich repeat (LRR) receptors (NLRs) directly or indirectly recognise pathogen-derived effectors to initiate innate immunity. In this study, we have identified Meloidogyne incognita secreted effectors MiTSPc and MiACPS, which can interact with resistance protein PsoRPM3 in Prunus sogdiana (P. sogdiana). In the leaves of PsoRPM3 transgenic tobacco plants and disease-resistant P. sogdiana lines, when the MiTSPc and MiACPS were transit expressed, significant hypersensitive response and high ion leakage rate were detected. Moreover, when the MiTSPc was silenced in M. incognita, galls were observed in the roots of PsoRPM3 transgenic tobacco plants. Co-localisation experiments have shown that MiTSPc and PsoRPM3 were overlapped. Our data revealed that LxxLxLxxN/CxL motif of PsoRPM3 LRR domain can recognise MiTSPc23-54aa.

The role of the DIVARICATA (DIV) transcription factor (TF) in Cd stress remains largely unclear. Here, nine DIVs were isolated from M. hupehensis based on CDS sequences of identified DIV members in Malus. Among them, MhDIV3 exhibited the earliest and strongest response to Cd. Its encoded protein, MhDIV3, possesses the characteristics of R2R3-MYB TF. Suppression of MhDIV3 in M. hupehensis roots and apple calli led to a higher fresh weight and lower levels of reactive oxygen species (ROS) and malondialdehyde (MDA) under Cd stress, while overexpression of MhDIV3 in M. hupehensis roots and tomato exacerbated Cd-caused oxidative damage by accelerating Cd2+ uptake. Mechanistically, MhDIV3 bound to an enhancer in the intron of MhNRAMP1 to positively regulate its expression under Cd stress. Additionally, miR156u/v, an upstream regulator of MhDIV3, suppressed MhDIV3 expression by complementing its 3'UTR. Overexpression of miR156u/v reduced Cd²⁺ uptake and stress damage, similar to MhDIV3-suppression. Overall, our results suggested that miR156u/v-MhDIV3 module positively modulates Cd uptake and damage by triggering MhNRAMP1 expression in M. hupehensis.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144705903","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 great efforts have been made to identify QTLs or genes related to low P stress in soybean, few studies have been reported on the root remodeling. Here, by performing genome-wide association study (GWAS) using 239 accessions and 62 124 single-nucleotide polymorphism (SNP) markers, 194 QTN regions related to seven root traits were screened, and 5 of 194 were colocated in at least three traits or environments. By performing comparative transcriptome analysis using low phosphorus tolerant genotype P375 and sensitive genotype P018 under low P stress, 621 DEGs were identified between normal and low P treatment and 1025 DEGs between P375 and P018. The integrated analysis of candidate genes within both QTLs and DEGs showed that GmPPC6 could be a staple gene. Overexpression and RNA interference of GmPPC6 in transgenic hairy roots indicated that GmPPC6 negatively affected root length (RL) and root surface area (SA) under low P stress. Together, this study further elucidates the systemic changes in genes induced by low P stress and provides valuable insight into the great potential of GmPPC6 under low P stress in soybean.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144705902","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 examined heat tolerance thresholds of photosynthetic light reactions in sun-exposed leaves of 12 tropical montane tree species with different strategies for growth and water use. Leaf chlorophyll a fluorescence, gas exchange, morphology and thylakoid membrane lipid composition were measured at three common gardens along an elevation and temperature gradient in Rwanda. Tree species with traits predisposing them to higher leaf temperatures, such as lower stomatal conductance and large leaves, had higher photosynthetic heat tolerance, but narrower thermal safety margins (TSMs). Photosynthetic heat tolerance partially acclimated to increased growth temperature, increasing by 0.31°C on average for every 1°C increase in growth temperature. Thus, TSMs were narrower for trees grown at the warmer sites. Heat tolerance and its acclimation were linked to the adjustment of thylakoid membrane lipid composition. Moreover, TSMs were larger in species with high leaf mass per area. Our results show that (i) leaf temperature is more important than heat tolerance in controlling interspecific variation in TSMs, and that (ii) tropical trees have limited ability to thermally acclimate to increasing temperatures.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144688420","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 climate change, drought conditions may contribute to the spread of geminiviruses through creating favourable conditions for whitefly proliferation. Additionally, lots of geminiviruses could enhance plant drought tolerance, supporting their survival and propagation. However, the effects of drought stress on plant resistance to geminiviruses remain unclear. In this study, we demonstrate that drought stress significantly reduces the accumulation of DNA viruses, including tomato yellow leaf curl virus and Sri Lankan cassava mosaic virus, while the accumulation of the +ssRNA virus turnip mosaic virus remains unaffected. We show that drought does not affect RNA silencing pathway. Interestingly, drought-induced abscisic acid (ABA) inhibits geminiviruses replication by reprogramming the cell cycle and suppressing the expression of proliferating cell nuclear antigen (PCNA), a component of DNA replication complex. Moreover, we identify that the ABA-responsive transcription factor NAC072 directly binds to the PCNA promoter, negatively regulating its expression. These findings provide mechanistic insights into the ABA-mediated resistance against DNA viruses during drought stress and highlight the critical role of ABA in integrating plant responses to abiotic and biotic stresses.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144688419","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}
