This review addresses several knowledge gaps regarding PSI by providing comprehensive insights into the structural diversity of PSI supercomplexes across various evolutionary groups, including cyanobacteria, algae and land plants. It clarifies the oligomerization states of PSI and its interactions with light-harvesting complexes (LHCs) and other protein complexes such as NDH and Cyt b6f. Environmental factors, including light intensity, iron availability and pH, significantly influence PSI's structure and function. These factors drive PSI's adaptability through conformational changes and the formation of specialized supercomplexes. For example, under iron deficiency, cyanobacteria form PSI-IsiA complexes to compensate for reduced PSI content. The diversity of PSI's light-harvesting antenna components, such as Lhca proteins in land plants and Lhcr proteins in red algae, is crucial for optimizing light absorption and energy transfer under varying light conditions. Structural evidence also supports the existence of PSI-PSII supercomplexes, revealing direct interactions that facilitate energy transfer between photosystems and protect them from photodamage. These findings highlight the evolutionary significance of PSI's structural diversity and its role in photosynthetic efficiency and environmental adaptation.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143699276","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}

AMF are mutualists of most land plants but suppress the growth of many plants within the Brassicaceae, a large plant family including many invasive species. Alliaria petiolata (garlic mustard) is a nonnative, nonmycorrhizal Brassicaceae distributed throughout North America in forest understories where native species rely on AMF. If AMF suppress growth of garlic mustard, it may be possible to inoculate AMF to manage invasions. Here, we show that in contrast to expectation, garlic mustard growth nearly doubled in response to AMF inoculation under both laboratory and field conditions. This effect was negatively linked to investments in glucosinolates, a class of defensive compounds. In contrast to typical symbiosis, AMF did not produce arbuscules where nutrient exchange occurs in roots, but AMF inoculation increased plant and soil nitrogen availability. Our findings reveal an adjacent pathway by which AMF promote invasive plant growth without classic symbiotic exchanges. Prior assumptions that garlic mustard suppresses AMF are inadequate to explain invasion success since it benefits from interactions with AMF. This study is the first to demonstrate extensive growth promotion following AMF inoculation in mustard plants, with important implications for invasion biology and agriculture.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143707953","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 photosynthetic responses of Phragmites australis, a model wetland plant with a broad geographic distribution, to temperature variations across three distinct temporal scales. We analysed short-term responses using net photosynthesis rate temperature curves, medium-term acclimation across three growth temperature regimes, and long-term adaptation of phylogeographical groups to their genotypic origins' climate. We demonstrated that the overall photosynthetic performance of P. australis is principally driven by thermal acclimation to growth temperature, comparing with local adaptation to climate of origin. Genotypes from diverse geographical regions demonstrated varied physiological strategies: those from higher latitudes exhibited remarkable plasticity, adjusting rapidly to optimise photosynthetic performances under changing thermal conditions. These intraspecific differences highlighted the role of evolutionary history in shaping species' potential resilience and adaptive capacity. This study also underscored the complex interplay between temperature, O2 sensitivity and photosynthetic efficiency, advancing our understanding of how widespread wetland species respond to ongoing global climate dynamics.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143699275","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}

In this study, we characterised a temperature-sensitive yellow leaf cotton mutant. Genome re-sequencing and comparison identified a 10.327 Kb deletion on the D12 chromosome (D12:670726-681053) in the mutant. The deletion region contains two annotated genes, GH_D12G0047 and GH_D12G0048. Investigations integrating gene mapping, comparative transcriptome analysis, gene annotation, virus-induced gene silencing and gene complementation, found deletion of GH_D12G0047 or GhSCY2D, a crucial constituent of the Sec2 complex essential for the function of chloroplasts, being responsible for the yellow leaf phenotype. The yellow leaf mutant had disrupted chloroplast structure and hindered chlorophyll synthesis when temperature was below 28°C but regained normal green leaf colour at 32°C. By analysing the transcriptome data and hormonal level changes of the mutant under conditions of 25°C and 32°C, it was found that the jasmonic acid signalling pathway and GhSCY2 work in concert to maintain the structural integrity of chloroplasts. The outcomes of the study reveal the indispensable role of GhSCY2 and jasmonic acid in sustaining chloroplast homoeostasis, providing new insights into the regulation of cotton leaf colour and paving the way for advancement in high photosynthetic efficiency breeding strategies.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143690433","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}

Intraspecific competition usually constrains root proliferation to minimize the overlap of root systems between competitors, especially in resource-impoverished environments. However, it remains largely unclear whether and how this decline in root nutrient-scavenging capacity can be complemented by other nutrient-acquisition strategies. Here, we leveraged 25 of 41-year-old Pinus Sylvestris var. mongolica monocultures with stand densities ranging from 350 to 1500 trees per hectare, reflecting a gradient of intraspecific competition intensity. In these stands, we measured variables of ecosystem nitrogen (N) status, needle N resorption efficiency, and nine root morphological, physiological and mycorrhizal traits. Results showed that increasing stand densities decreased soil N transformation rates and carbon-:N-acquisition enzyme ratios, indicating an increasing degree of N deficiency. High-density stands had lower root length density than low-density stands, implying intense intraspecific competition causing root segregation. Conversely, stand density was positively correlated with the relative abundance of ectomycorrhizal fungi (EMF) with genetic potential to produce class II peroxidases. Collectively, these findings highlight that the decline of plant-available soil N may account for root segregation under intraspecific competition and suggest the complementarity of fine roots and EMF in nutrient acquisition at the intraspecific level.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143668680","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}

In this study, we identified six growth regulating factors (GRFs) in Catharanthus roseus through genome sequence analysis, and notably, two GRFs, CrGRF1 and CrGRF4, exhibited responsiveness to light signals. By manipulating the expression of CrGRF1 and CrGRF4 in C. roseus leaves, both through overexpression and silencing, we observed their capacity to enhance the accumulation of monoterpenoid indole alkaloids (MIAs) by upregulating the expression of 10-hydroxygeraniol oxidoreductatse (Cr10HGO) and 7-deoxyloganetic acid synthase (Cr7DLS). Furthermore, yeast one-hybrid and dual-luciferase reporter assays confirmed that CrGRF1 and CrGRF4 directly activate Cr10HGO expression by binding to the TFmatrixID_0441 cis-elements (ctTTCAGa) within its promoter region. This study sheds new light on the crucial role played by the growth regulating factor (GRF) gene family in regulating specialised metabolic pathways in plants. Elucidating the roles of CrGRF1 and CrGRF4 lays an essential foundation for future research to decipher the molecular mechanisms governing light-controlled MIA production in C. roseus.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143668704","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}

However, the transcriptome profiling and key regulatory factors of SE in the woody magnoliid Liriodendron hybrid remain unclear. Here, we depicted the time-series transcriptome profiling of SE in Liriodendron hybrid, highlighting the temporal significance of morphogenic genes like BBM in embryogenic callus and developing somatic embryos. Expression patterns were validated using qRT-PCR and transgenic lines expressing β-glucuronidase (GUS) and red fluorescent protein mCherry driven by the LhBBM promoter. Overexpression of LhBBM, both constitutive (CaMV 35S promoter) and SE-specific (Liriodendron WOX9 promoter), enhanced SE and embryonic callus induction. Conversely, CRISPR/Cas9-mediated knockout of LhBBM reduces SE efficiency without compromising callus induction. Furthermore, we developed a secondary callus induction method that minimized the heterogeneity of a transgenic callus line, confirming the sufficiency and necessity of LhBBM in SE. Notably, LhBBM significantly improved genetic transformation efficiency in Liriodendron. These findings establish LhBBM as a promising target for enhancing SE capacity and SE-based transformation efficiency, particularly in forest trees.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143661863","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}
