It has been postulated that the evolutionary transition from freshwater streptophyte algae to land plants, or the canalization of plant meiosis, was completed during the Middle Ordovician (~460 Ma). However, the absence of undisputed streptophyte algal fossils (for example, Charophyceae) earlier than the late Silurian (~425 Ma) has obscured this link between streptophyte algae and land plants. Here we describe a marine Charophyceae fossil, <i>Tarimochara miraclensis</i> gen. et sp. nov., from early and middle Katian (Late Ordovician, ~453–449 Ma) marine limestones in northwestern China. This discovery demonstrates that at least some species of Charophyceae inhabited shallow normal marine environments at that time. Moreover, these early Charophyceae show that some key morphological innovations associated with an evolutionary transition between streptophyte algae and land plants had occurred before the early Katian. This provides crucial evidence relevant to the origins of land plants.</p>","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"3 1","pages":""},"PeriodicalIF":18.0,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144176810","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}

While a portion of photosynthesis-originated sugars is metabolized through glycolysis upon entering the cytosol, the remainder is reversibly channelled to the vacuole, mediated by different families of vacuolar sugar transporter (VST) located on the vacuolar membrane, the tonoplast. Historically, sugar transporters operating on plasma membranes have been studied more than those on tonoplasts. Recently, however, several breakthroughs have shed light on (1) the distinct roles of VSTs in plant development and stress responses and (2) how seemingly unrelated classes of VSTs act together to modulate sugar influx into and efflux from the vacuoles. Here we evaluate these advances, analyse the evolution of VSTs and identify knowledge gaps and future directions for better understanding and manipulation of cytosolic–vacuolar sugar exchange to optimize plant performance.</p>","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"45 1","pages":""},"PeriodicalIF":18.0,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144104737","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}

EGT is a still-ongoing process, but the molecular mechanisms determining its frequency remain largely unknown. Here we demonstrate that nuclear double-strand break (DSB) repair is a strong suppressor of EGT. Through large-scale genetic screens in tobacco plants, we found that EGT from plastids to the nucleus occurs more frequently in somatic cells when individual DSB repair pathways are inactive. This effect is explained by the expected increase in the number and residence time of DSBs available as integration sites for organellar DNA. We also show that impaired DSB repair causes EGT to increase 5- to 20-fold in the male gametophyte. Together, our data (1) uncover DSB levels as a key determinant of EGT frequency, (2) reveal the strong mutagenic potential of organellar DNA and (3) suggest that changes in DNA repair capacity can impact EGT across evolutionary timescales.</p>","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"4 1","pages":""},"PeriodicalIF":18.0,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144066046","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 final meristemoid further differentiates into a guard mother cell, which divides symmetrically to produce two guard cells. The asymmetric divisions of the meristemoid mother cell are initiated by SPCH, whereas MUTE is required for termination of asymmetric divisions and further differentiation of the meristemoid into the guard mother cell. Finally, FAMA is required for symmetric division of the guard mother cell. SPCH, MUTE and FAMA can all form heterodimers with SCREAM; however, the specific role of SCREAM in stomatal development is less clear.</p><p>The researchers investigate stomatal development in <i>scrm</i> mutants and find that differentiation of stomatal-lineage cells into guard cells is inhibited. Although the number of asymmetric cell divisions in <i>scrm</i> mutants differs between developmental stages compared with the wild type, lack of SCRM generally leads to excessive asymmetric cell divisions of meristemoids. As overexpression of <i>SCRM</i> leads to increased stomatal-lineage density but not stomatal density, it seems that SCRM is required both for the initiation and termination of asymmetric cell division at different stages. Transcription of SPCH and known SPCH targets is enhanced in <i>scrm</i> mutants, and indeed SCRM can directly bind and repress the <i>SPCH</i> promoter. It is further shown that <i>SPCH</i> is epistatic to <i>SCRM</i> and that downregulation of <i>SPCH</i> expression in the <i>scrm</i> background can partially suppress the excessive asymmetric cell divisions, suggesting that this phenotype can be at least partially attributed to upregulation of <i>SPCH</i> in the <i>scrm</i> mutant. Overexpression of <i>SCRM</i> in the <i>mute</i> background leads to fewer asymmetric cell divisions than in <i>mute</i> alone, and MUTE does not bind to the <i>SPCH</i> promoter in vivo, pointing to a role for SCRM in the termination of asymmetric cell divisions that is independent of MUTE. As it was shown before that SPCH can also be inhibited by non-cell autonomous patterning signals, it is tempting to speculate that relative quantities of SPCH and SCRM may determine the initiation or termination of asymmetric cell division.</p>","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"5 1","pages":""},"PeriodicalIF":18.0,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144066043","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 uncover stereotypical ACR patterns at young TEs that degenerate with evolutionary age, resulting in TE enhancers preferentially marked by a novel plant-specific epigenetic feature: simultaneous hyper-CpG methylation and chromatin accessibility. We show that TE ACRs are co-opted as gene promoters and that ACR-containing TEs can facilitate gene amplification.
