Herein, we measured root exudate composition of 20 woody species and assessed its associations with root traits and rhizosphere microbiota to investigate the ecological functions of root exudates throughout plant evolution. The root exudates showed increased richness, polarity, unsaturation and aromaticity with divergence time. Furthermore, fungal richness markedly increased with divergence time, accompanied by the rhizosphere enrichment of copiotrophic bacteria (e.g., Bacteroidota and Actinobacteriota), ectomycorrhizal fungi and several functional microbes. Additionally, competitive root traits (e.g., specific root length and root nitrogen concentration) were positively correlated with exudate richness and chemical complexity in ectomycorrhizal (EcM) trees, whereas they were related to the exudation rates in the arbuscular mycorrhizal (AM) trees. Microbial richness and strategies were closely linked to exudate chemistry, and the exudate-microbe interactions were more tightly coupled in the rhizosphere of EcM trees than in that of the AM trees. Shifts in exudate composition and their associated microbial communities may reflect enhanced chemical defense and rhizosphere communication as plants evolve. These results provide evidence that root strategies extend beyond the root itself to include exudates and the rhizosphere, thereby advancing our understanding of root traits-exudate-microbiota associations across plant evolution.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":"8385-8399"},"PeriodicalIF":6.9,"publicationDate":"2026-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148443571","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}

Bamboo plays an integral role in mitigating climate change with its excellent photosynthetic carbon fixation capacity. The Golden2-like (GLK) transcription factor is a critical regulator of photosynthesis. In this study, we identified four GLK members in moso bamboo (Phyllostachys edulis), among which PeGLK1-1 functioned as a principal regulator of photosynthesis. Overexpressing PeGLK1-1 significantly enhanced the carbon fixation capacity of transgenic rice under elevated CO2 (eCO2) environment. Moreover, PeGLK1-1 was positively correlated with most photosynthesis-related genes, such as PeRbcS2 and PePRK1 in the Calvin cycle. PeGLK1-1 bound to 5'-AAAAA-3' in the promoters of PeRbcS2 and PePRK1, thereby activating their transcription. Furthermore, overexpressing PeRbcS2 and PePRK1 enhanced the photosynthetic capacity of transgenic rice under eCO2 environment. In planta gene editing of PeRbcS2 and PePRK1 led to a decrease in photosynthetic capacity, whereas transient overexpression of them exhibited opposite trends. Collectively, eCO2 environment could induce the expression of PeGLK1-1 to activate the Calvin cycle genes, ultimately enhancing the carbon fixation capacity. This study provides crucial evidence for GLK regulating the Calvin cycle, which will contribute to breeding new bamboo varieties with efficient carbon fixation capacity.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":"8368-8384"},"PeriodicalIF":6.9,"publicationDate":"2026-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148434559","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}

Here, we identified a key oxidosqualene cyclase gene, RrOSC5, which encodes a functional cycloartenol synthase and is dynamically upregulated under UV-B stress. Overexpression of RrOSC5 enhanced sterol accumulation in both native and transgenic hosts, significantly improving their UV-B resistance. We further discovered that the transcription factor RrNAC2 directly binds to a non-canonical AC-rich repeat within the RrOSC5 promoter, activating its transcription. Crucially, heterologous overexpression of RrNAC2 in tobacco conferred the enhanced UV-B tolerance, establishing its role as a core regulator in this pathway. Notably, we found that the master UV-B signalling regulator RrHY5 physically interacts with RrNAC2, thereby integrating the RrNAC2-RrOSC5 sterol module Into the canonical UV-B signalling pathway. Our findings revealed a hierarchical RrHY5-RrNAC2-RrOSC5 cascade governs UV-B-induced sterol defence, wherein RrNAC2 drives protective sterol biosynthesis via RrOSC5, and both components synergistically enhance antioxidant and osmotic adjustment defences. This work provides novel insights into sterol-mediated plant adaptation to UV-B stress for molecular breeding of fruit plants.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":"8626-8642"},"PeriodicalIF":6.9,"publicationDate":"2026-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148547299","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 plant-specific endoplasmic reticulum (ER)-resident PHOSPHATE TRANSPORTER TRAFFIC FACILITATOR1 (PHF1) is structurally related to SEC12, which initiates the coat protein complex II (COPII) assembly as a guanine nucleotide exchange factor (GEF) by activating the small GTPase SAR1. In contrast, PHF1 loses the conserved catalytic residues critical for GEF activity and specifically assists the ER exit of the PHT1 transporters. However, the underlying molecular mechanism remains unknown. In this study, we showed that overexpression of Arabidopsis thaliana PHT1;1 (AtPHT1;1) in the tobacco relative Nicotiana benthamiana transient expression system caused a portion of AtPHF1 to distribute into AtSAR1b- and AtSEC24a-labelled ER exit sites (ERES). We demonstrated that AtPHF1 interacts with AtSAR1b and AtSAR1c based on tripartite split-GFP association in agro-infiltrated N. benthamiana leaves and verified this interaction using miniTurbo-based proximity labelling. We also confirmed its physiological relevance by co-immunoprecipitating endogenous AtPHF1 with AtSAR1c-GFP in Arabidopsis transgenic lines. Importantly, AtPHF1 preferentially interacts with GDP-locked AtSAR1. Therefore, we propose that AtPHF1 or the AtPHT1;1-AtPHF1 complex interacts with SAR1 GTPase to participate in the early step of COPII assembly for the ER export of PHT1 transporters.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":"9246-9264"},"PeriodicalIF":6.9,"publicationDate":"2026-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148710825","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}
