Plants have developed various strategies to alleviate salinity stress's negative effects, including polyamine redistribution by polyamine uptake transporters (PUTs). However, the mechanisms by which PUTs alter polyamine translocation processes during salt stress have not been fully elucidated. Here, we show that disruption of PUT2, which is involved in polyamine shoot-to-root transport, results in salt sensitivity phenotypes in tomato. Moreover, yeast one-hybrid screened for an HD-Zip transcription factor HB52 that interacts with PUT2, and loss of function of HB52 also led to increased sensitivity to salt stress, whereas HB52-overexpression lines exhibited improved salt tolerance. Furthermore, molecular analyses demonstrated that HB52 directly activated the expression of PUT2 and facilitated Na+ efflux by promoting polyamine shoot-to-root mobility. This study uncovers a synergistic transcriptional regulatory network associated with a homeobox protein regulator that promotes polyamine long-distance transport under salt stress.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143750402","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 gene OsCCT23 encoding a CCT domain-containing protein that delays heading by over 40 days and increases grain yield by 60-104% through overexpressing. Two types transcripts OsCCT23L and OsCCT23S were isolated by 5'RACE, and transgenic events demonstrated that the effect of the predominant transcript OsCCT23S, encoding an 81-aa protein without the B-box domain, is comparable to OsCCT23. OsCCT23 is predominantly expressed in leaves and follows a diurnal expression pattern with a peak at dawn. Overexpressing OsCCT23 upregulated the floral repressor Ghd7 and downregulated the floral inducer RID1, consequently led to the downregulation of Ehd1, Hd3a and RFT1. Additionally, it regulates the expression of certain circadian clock-related genes, including OsGI and OsTOC1. RNA in situ hybridisation analysis confirmed that OsCCT23 activates the expression of Ghd7 in the panicle branch meristem. OsCCT23 suppresses the expression of four OsCKX genes including Gn1a, which associate with cytokinin accumulation in panicles. Natural variation in OsCCT23 promoter identified by eGWAS associates its mRNA abundance and rice heading date. Consequently, OsCCT23 substantially delays heading and significantly increases grain yield, making it highly valuable for rice breeding.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143750419","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 contrast to existing software, these automated tools use derivative-free optimizers to ensure close fits and they calculate non-Gaussian confidence intervals to indicate which parameter values are most reliable. Results from PhotoGEA's C3 A-Ci curve fitting tool are compared against other available tools, where it is found to achieve the closest fits and most reasonable parameter estimates across a range of curves with different characteristics. PhotoGEA's C3 Variable J and C4 A-Ci fitting tools are also presented, demonstrating how they can provide insights into mesophyll conductance and the processes limiting C4 photosynthesis at high CO2 concentrations. PhotoGEA enables users to develop data analysis pipelines for efficiently reading, processing, fitting and analysing photosynthetic gas exchange measurements.

Understanding the comprehensive mechanisms regulating dormancy in poplar is vital for the genetic improvement of forest trees. However, previous studies have typically used mixed-sample extraction, which fail to capture spatial tissue-specific responses. This study provides precise spatial lipidomics analysis of poplar buds during phases of growth and dormancy by employing an innovative technique combining liquid chromatography-tandem mass spectrometry with matrix-assisted laser desorption/ionization mass spectrometry imaging (MALDI-MSI) for precise spatial lipidomics analysis of poplar buds during phases of growth and dormancy. MALDI-MSI revealed that most phospholipids were uniformly distributed across all tissues in growing buds but localized in the bud axis during dormancy. Moreover, triacylglycerols, which serve a storage function, were observed to accumulate mainly within the shoot apical meristem tissue during dormancy. These findings highlight the unique spatial distribution patterns of lipids during bud growth and dormancy in poplar, emphasize the role of lipid metabolism in adapting to seasonal changes, and provide new approach for elucidating the lipidomics of seasonal growth patterns in trees.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143750451","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 investigated the response of tiller-related traits to nitrogen availability during barley domestication and breeding, aiming to identify genetic resources with high NUE. A total of 305 barley accessions were analyzed under two nitrogen levels, focusing on six tiller-related traits and their relationship with nitrogen supply. Domestication reduced tillers per plant (TPP) and nonproductive tillers per plant (NTPP), while breeding increased spikes per plant (SPP), proportion of productive tillers (PPT), and Spike-response to nitrogen (SRN). SRN was used as a key indicator to evaluate spike development under varying nitrogen conditions. Genome-Wide Association Study (GWAS) and RNA-seq analysis identified HvNLP4 as a key candidate gene regulating SRN, with haplotype analysis revealing that HvNLP4Hap1, associated with high SRN, underwent strong positive selection during domestication and breeding. Moreover, HvNLP4Hap1 exhibited weaker induction under low nitrogen conditions, suggesting that avoiding its selection in future breeding programmes may enhance NUE in barley. These findings provide valuable insights for developing sustainable barley cultivars with improved nitrogen efficiency.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143750415","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, it is unclear how exogenous calcium strengthens the cyclic electron transfer (CET) to attain optimal carbon flux. To assess the nutrient fortification role of Ca2+ (15 mM) in facilitating this process for peanuts, we added antimycin (AA, 100 μM) and rotenone (R, 100 μM) as specific inhibitors. Our results revealed that inhibiting CET caused a negative effect on photosynthesis. The Ca2+ treatment accelerated the turnover of non-structural carbohydrates, and linear electron carriers while balancing the photosystem I (PSI) bilateral redox potential. The treatment also strengthened the PROTON GRADIENT REGULATION5 (PGR5)/PGR5-LIKE PHOTOSYNTHETIC PHENOTYPE1 (PGRL1) and the NADH dehydrogenase-like (NDH)-mediated CET, with plausible crosstalk between thioredoxin (Trx) system and Ca2+ signalling, to regulate chloroplast redox homoeostasis. Specifically, exogenous Ca2+ strengthened the PGR5/PGRL1-mediated CET by providing sufficient ATP and adequate photoprotection during the long-term exposure; the NDH-mediated CET served to alleviate limitations on the PSI acceptor side by translocating protons. This study demonstrated the effectiveness of harnessing optimal nutrient supply, in the form of foliar Ca2+-based sprays to strengthen the eco-physiological resilience of peanuts against cold stress.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143750454","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}

Recent evidence has shown that marine phytoplankton may acclimate and adapt to long-term OW. Whether and how marine diatoms-a functional group of phytoplankton that contributes to 40% of marine primary production-can adapt to long-term OW remains virtually unknown. The model marine diatom Phaeodactylum tricornutum was subjected to thermal stress (25°C, compared to the Control at 20°C) for 400 days (~400 generations), and physiological, transcriptomic, genetic and epigenetic analyses were performed to reveal the adaptation mechanisms under long-term OW. During the adaptation, regulation of resource allocation (e.g., photosynthesis, nitrogen metabolism, ribosomal synthesis and translation, carbon metabolism and heat shock response) at the genetic and transcriptional levels was linked to accumulated proteins, carbohydrates and particulate organic carbon, reduced lipid content, and enlarged cell size. Integrated analyses of histone modification (H3K27me3) and transcriptome data sets revealed the potential role of transposable elements and epigenetic regulation of transposable elements via histone modification in the adaptation of P. tricornutum to long-term thermal stress. These mechanistic insights may facilitate the modelling and prediction of OW-induced impacts on marine phytoplankton in the future.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143750406","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 interactive effects of these two stresses are barely explored. We investigated the physiological and growth responses of Acer campestre, Fagus sylvatica, Quercus robur and Quercus petraea saplings to artificially induced LSF and drought, focusing on stomatal gas exchange, carbon partitioning, nonstructural carbohydrates (NSCs), phenology and tree growth. LSF depleted NSCs and changed carbon allocation patterns 1 month after the event. Additionally, LSF decreased diameter increment and root growth of A. campestre and F. sylvatica in the current year. Drought affected gas exchange of all species, decreased NSCs of A. campestre, reduced biomass of Q. robur, and exacerbated the detrimental LSF effect on Q. robur's NSCs. Our findings indicate that saplings prioritized canopy restoration immediately after LSF, and favored reserve replenishment before growth until the end of the growing season. Furthermore, we highlight the risk that LSF and drought in the same year could push tree species beyond their physiological limits and we emphasize the importance of studying multiple stressors' interactions to better understand threshold effects that could profoundly alter forest ecosystems.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143750393","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}
