Deciphering their genetic variation is therefore essential for understanding geographic adaptation to abiotic stresses. Here, we assembled a high-quality genome of Apocynum pictum, and, through comparison with the A. venetum genome, identified abundant genome-wide structural variations, particularly tandem gene duplications (TDs). For instance, a key TD spanning 19 tandem SRP genes was found in A. pictum, compared to only four in A. venetum. We further performed whole-genome resequencing of 280 individuals from natural populations of A. venetum and A. pictum that were widely distributed across arid and saline-alkali regions in northern China. We revealed a distinct geographical distribution of six genetic population clusters in the current landscape. Demographic inference identified a severe population decline during the Last Glacial Maximum, while genetic offset analysis forecasted high vulnerability to future climate change in the mountains and Tarim Basin for both species. TDs, for example, tandemly duplicated LRR-RLK, ABCG, and TLP genes, were under significant selection, as revealed by both selective sweep analysis between A. venetum and A. pictum and genome-environment association analysis with temperature and precipitation variables. TLP overexpression in tobacco enhanced drought tolerance by alleviating oxidative damage. Furthermore, a dual-luciferase assay confirmed that the A. pictum TLP promoter haplotypes carrying selection signals exhibited higher transcriptional activity than their counterparts in A. venetum. Our findings highlighted the combined roles of gene dosage effects and regulatory sequence selection of frequent stress-resistant TDs in harsh environments.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":"9192-9210"},"PeriodicalIF":6.9,"publicationDate":"2026-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148710830","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}

Expression of mutant versions of AtPPC1 in an Arabidopsis ppc1 loss-of-function mutant increased Al resistance in association with upwards of threefold higher release of Al-chelating malate from roots. Analyses of enzyme kinetics and protein structure of the variants revealed that each amino acid position is critical to proper interplay between the allosteric regulator malate and the active site. Since these affect amino acid positions generally conserved amongst plant PPCs, they were individually introduced into maize PPCs including ZmPPC1, the isozyme responsible for the first step of C4 photosynthesis, and ZmPEP7, a key PPC in resupply of the TCA cycle via anaplerosis. This resulted in similar or greater improvements in enzyme activity and reduced regulation in vitro for both ZmPPC1 and ZmPEP7 along with increased PPC-dependent output in planta for a ZmPEP7 transgenic. Therefore, engineering these amino acid changes into plants in general could be useful for increasing carbon fixation by PPCs to turn excess CO2 into a resource for our growing population.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":"8306-8321"},"PeriodicalIF":6.9,"publicationDate":"2026-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13646687/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148434544","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consequently, growth responses of C4 plants to elevated CO2 (eCO2) are generally attributed to indirect improvements in plant water relations. However, it remains unclear whether sustained exposure to eCO2 also induces changes in photosynthetic capacity that contribute directly to carbon gain. We examined the interactive effects of CO2 concentration and soil water availability on photosynthesis, biochemical capacity, and growth in three African C4 grasses grown under ambient (400 ppm) and elevated (550 ppm) CO2. Elevated CO2 increased net photosynthesis across species, with stronger responses under drought. Intrinsic water-use efficiency increased primarily through enhanced assimilation, while stomatal responses were contingent on water availability rather than driven directly by elevated CO2. Importantly, eCO2 induced species- and context-dependent increases in apparent photosynthetic capacity after prolonged treatment exposure. Megathyrsus maximus showed strong Vcmax increases under both water treatments and Jmax upregulation under well-watered conditions, Heteropogon contortus exhibited biochemical upregulation primarily under drought, and Themeda triandra showed little evidence of acclimation. Growth responses closely mirrored these physiological patterns, occurring only in species exhibiting coordinated biochemical adjustment. These results indicate that C4 responses to eCO2 cannot be explained solely by stomatal water saving and provide evidence that species-specific changes in apparent photosynthetic capacity may contribute to sustained carbon gain, particularly under water limitation.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":"8870-8882"},"PeriodicalIF":6.9,"publicationDate":"2026-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13646657/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148663067","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although FT/TFL1 members share highly conserved structural features, they exhibit remarkable functional divergence. The FT generally promotes floral induction, whereas TFL1 delays or represses it, forming an antagonistic regulatory balance. However, increasing evidence from comparative genomics and molecular studies suggests that the classical 'FT activator/TFL1 repressor' paradigm cannot adequately account for the complex behaviours of expanded gene families across diverse species, tissue types, and environmental conditions. In this review, FT/TFL1 copy-number variation and expansion patterns during plant evolution are synthesised, mechanisms of functional diversification are summarised, and insights from protein interaction rewiring and environmental signal integration are integrated.

Under environmental stresses, vesicular trafficking regulates the localisation, activity, recycling, and degradation of ion transporters, which, in turn, take vital part in maintaining osmotic, ionic and pH homoeostasis required for vesicle formation, sorting, and fusion. This review outlines the major vesicular trafficking pathways, vesicle types, and the key regulatory proteins involved in vesicle trafficking. It also provides an in-depth discussion on how vesicle trafficking interacts with ion transport systems during nutrient imbalance, heavy metal toxicity, salt stress, drought, osmotic stress, and pH disturbance. Across these abiotic stress regimes, recurring regulatory principles emerge, including post-translational modification-dependent transporter sorting, TGN/EE-centred cargo decision-making, SNARE-mediated coupling of vesicle fusion with channel activity, and feedback regulation between ion gradients and membrane trafficking. We propose that the crosstalk between vesicle trafficking and ion transport constitutes a dynamic cellular framework that enables plants to integrate environmental signals with ion homoeostasis and developmental plasticity. The synthesis advances our understanding of vesicle trafficking functions and ion transporters regulatory pathways, providing a comprehensive reference for research in this field.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":"8070-8098"},"PeriodicalIF":6.9,"publicationDate":"2026-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148403084","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 review critically distinguishes these interaction types and moves beyond single‑stress frameworks to provide a multiscale synthesis of plant responses, soil water-salt dynamics, root‑system plasticity, rhizosphere microbiome modulation, emerging breeding modelling and agronomic tools. This review provides a detailed overview of the multilevel damage from these co-occurring stresses, including osmotic shock, ionic toxicity and systemic oxidative damage, and examines plant strategies such as ion homoeostasis, osmotic adjustment and antioxidant responses. Beyond plant-centric views, the review explores epigenetic reprogramming for stress memory and the potential of rhizosphere microbiome engineering with plant growth-promoting rhizobacteria as a biological stress-alleviation strategy. It critically examines how high-throughput multiomics techniques, combined with innovative breeding methods, provide a transformative approach to decode complex tolerance traits and accelerate cultivar development. These techniques cover genomics, epigenomics, transcriptomics, proteomics and metabolomics, while the breeding methods include genomic selection and CRISPR-Cas gene editing. Despite progress, key challenges remain: validating combined stress resilience under field conditions, harnessing epigenetic inheritance and integrating microbial solutions into breeding pipelines. We propose a unified framework that merges mechanistic discovery, microbiome-assisted breeding, soil and water management and systems-level predictive modelling. This integrative approach is essential for developing climate-resilient crops to sustain dryland agriculture.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":"9029-9053"},"PeriodicalIF":6.9,"publicationDate":"2026-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148682744","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}

Seven candidate effectors were up-regulated at parasitism stages; in situ hybridization detected three effectors in subventral oesophageal glands and four in the dorsal oesophageal gland.

Protein-protein interaction tests identified TaCYPA-1 as a wheat target of Hf70514. Transient silencing of TaCYPA-1 significantly enhanced H. filipjevi parasitism, accompanied by down-regulation of defence-related genes.
