However, the regulatory mechanisms by which histone acetylation modulates RNA polymerase II phosphorylation in plants remain unclear. Here we show that two functionally redundant bromodomain-containing proteins, global transcription factor group E2 (GTE2) and GTE7, can bind to acetylated histone H4. Both GTE2 and GTE7 interact with cyclin-dependent kinase-like 9 (CDKL9), which belongs to a plant-specific CDKL group. Unlike canonical CDKs, CDKL9 functions in a cyclin- and CDK-activating-kinase-independent manner and can phosphorylate at least the serine 2 and serine 5 residues of the carboxy-terminal domain in vitro. The GTE2/GTE7–CDKL9 complex is required to maintain serine 2 and serine 5 phosphorylation under heat stress. Consistently, loss-of-function gte2/gte7 and cdkl9 mutants show similar heat-sensitive phenotypes. We also demonstrate that the acetylated-histone-binding activity of GTE7 is essential for the association of CDKL9 with chromatin and for plant heat tolerance. Together, these findings provide mechanistic insight into transcriptional regulation via histone acetylation in response to heat stress and suggest that plants might have evolved a unique group of carboxy-terminal domain kinases for stress tolerance. Zheng et al. identify a non-canonical RNA polymerase II kinase, CDKL9, that tends to act when plants are under heat stress. Acetylated-histone-binding proteins GTE2 and GTE7 help CDKL9 localize to targets. All of these proteins are important for plant heat tolerance.","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"11 7","pages":"1416-1428"},"PeriodicalIF":13.6,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144586949","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 underlying molecular mechanism is still unclear. Here, by examining the model plants Arabidopsis and tobacco, we confirmed that the distinct feature occurred at the guard cell level. Next, with both single-cell RNA sequencing and transcriptome sequencing, we compared gene expression patterns of adaxial and abaxial guard cells and highlighted the possibility of different utilization of potassium ion (K+) channels. Via in silico OnGuard simulation and genetic modifications, we found that adaxial and abaxial guard cells rely on different K+in channels, which control K+ influx for stomatal opening. The present study provides insights into understanding the distinct stomatal light response of different leaf surfaces. This study combines single-cell RNA sequencing, in silico OnGuard simulation and genetic modification approaches to reveal distinct compositional differences in the potassium ion channel between adaxial and abaxial guard cells.","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"11 7","pages":"1260-1269"},"PeriodicalIF":13.6,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41477-025-02026-5.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144586948","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}

Yet, the relative role of soil water supply (indicated by soil moisture) and atmospheric water demand (indicated by vapour pressure deficit, VPD) on GPP remains debated, primarily due to their strong covariations, the presence of confounding factors and unresolved causal relationships among the interconnected hydrometeorological drivers of GPP. Here using a causality-guided explainable artificial intelligence framework, we show that soil moisture is the dominant regulator of water stress, surpassing the role of VPD, when and where soil water supply limits ecosystem functions. Temporally, we use in situ flux tower data to demonstrate that soil moisture dominates the GPP response during periods of insufficient soil water supply. Spatially, we assess the global spatial patterns of satellite sun-induced chlorophyll fluorescence (a proxy for GPP) in water-limited regions and demonstrate that they are mostly dominated by soil moisture. Conversely, VPD plays a greater role in controlling the temporal and spatial variations in GPP than soil moisture when and where soil water supply is not limited. The relative role of soil moisture and VPD is modulated by plant adaptation to long-term climatological aridity. Our findings advance the understanding of the impacts of soil and atmospheric dryness on ecosystem photosynthesis. They provide crucial insights into how terrestrial ecosystems respond to increasing aridity and more frequent droughts, particularly given the potential ecosystem shifts from energy to water limitation. Using a causality-guided explainable AI framework, Liu et al. show soil moisture dominates vapour pressure deficit in shaping global photosynthesis during water-limited conditions.","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"11 7","pages":"1390-1400"},"PeriodicalIF":13.6,"publicationDate":"2025-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144568773","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}

Initially, systemin was conceived as a hormone-like, long-distance messenger that triggers systemic defence responses far from the site of insect attack. It was later found to rather act as a phytocytokine, amplifying the local wound response for the production of downstream signals that activate defence gene expression in distant tissues4. Systemin perception and signalling rely on the systemin receptor SYR15. However, the specifics of SYR1-dependent signalling and how systemin signalling differs from other immune signalling pathways remain largely unknown. Here we report that systemin activates the poltergeist-like phosphatase PLL2 in a SYR1-dependent manner. PLL2, in turn, regulates early systemin responses at the plasma membrane, including the rapid inhibition of proton pumps through dephosphorylation of their regulatory C-termini. PLL2 was found to be essential for downstream defence gene induction, ultimately contributing to insect resistance. The phosphatase PLL2 was identified as a specific component in systemin-induced immune signalling. PLL2 regulates proton pump activity at the plasma membrane and is required for downstream defence gene induction and insect resistance.","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"11 7","pages":"1270-1281"},"PeriodicalIF":13.6,"publicationDate":"2025-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12283378/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144564973","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}

Despite important advances in understanding various types of regeneration, the mechanism by which plants determine regeneration outcomes remains largely unknown. Here we demonstrate in Arabidopsis that a trade-off between two regeneration fates, wound-induced callus and root regeneration, was driven by distinct molecular pathways related to cambium and root development, respectively. We discovered that local water availability near the wound site determined the early stages of regeneration fates in Arabidopsis and tomato, with high water triggering root fate and low water initiating callus fate. Distinct spatial distributions of auxin response maxima around the wound, shaped by water availability, were critical for determining root or callus fates. We found that, by perturbing auxin response or auxin transport dynamics, we could change regeneration outcomes. Moreover, high water availability enhanced ethylene and jasmonic acid responses, whereas treatments with these hormones could modify auxin transport dynamics or the location of auxin response maxima, thus influencing regeneration fates. We propose that, through stress hormones, water availability modifies the auxin response distribution to control regeneration outcomes, thus allowing environmental control of regeneration and providing a means to improve in vitro regeneration by changing the water potential. This study reveals that water availability at the wound determines plant regeneration outcomes. High water availability induces root regeneration whereas low water availability triggers callus formation via stress hormones that shape auxin response maxima to activate distinct regeneration pathways.","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"11 7","pages":"1367-1379"},"PeriodicalIF":13.6,"publicationDate":"2025-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12283381/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144564974","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}

Here we demonstrate that the F-box protein FLAVIN-BINDING, KELCH REPEAT, F-BOX 1 (FKF1) and its interacting partner GIGANTEA (GI), central regulators of photoperiodic flowering, target SHORT VEGETATIVE PHASE (SVP) for 26S-proteasome-dependent degradation to regulate the temperature-responsive developmental transition to flowering. At low temperatures, GI is sequestered in liquid-like nuclear condensates. By contrast, FKF1 accumulates at high temperatures and releases GI from condensates to form a nuclear-dispersed FKF1–GI complex, leading to SVP degradation under short-day conditions. Temperature sensitivity is significantly reduced in fkf1-t, gi-2 and fkf1-2 gi-2 mutants. We propose that the FKF1–GI complex mediates the proteolysis of a floral repressor via reversible liquid–liquid phase separation to accelerate floral transition at high temperatures. GI forms an inactive nuclear condensate that is dispersed at high temperatures by FKF1 binding to GI’s intrinsically disordered region. The resulting FKF1–GI complex promotes SVP degradation, accelerating flowering at high ambient temperatures.","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"11 7","pages":"1282-1297"},"PeriodicalIF":13.6,"publicationDate":"2025-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144564972","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}
