However, ABA is often viewed cautiously as stomatal closure limits CO2 uptake for photosynthesis and growth. We have demonstrated that ectopic expression of selected ABA receptors in Arabidopsis reduces transpiration without growth penalty, thus achieving high water use efficiency (WUE). The tissues and mechanisms underlying this trait remain unclear, though prior evidence suggests a significant contribution from shoot ABA responsiveness. We hypothesize that guard-cell ABA signaling contributes to the trait of high WUE without growth penalty. We generated lines overexpressing 14 individual ABA receptors under the guard cell-specific promoter and examined leaf growth, transpiration, water potential, and net carbon assimilation rate (AN). We found that guard-cell overexpression of specific ABA receptors reduced transpiration and AN compared to the wild-type under well-watered conditions, but leaf growth was not adversely affected. The mechanism involved receptor-mediated reduction in transpiration and resultant improved leaf water potential for efficient intermediate-aged leaf growth. Under drought, these lines showed enhanced WUE without compromising biomass accumulation. Our findings highlight activation of ABA signaling in guard cells as a promising strategy for developing water-saving crops without growth trade-offs.","PeriodicalId":214,"journal":{"name":"New Phytologist","volume":"21 1","pages":""},"PeriodicalIF":9.4,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144701313","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}

Monitoring Ci assimilation rates in vivo is a major challenge in analyzing photoautotrophic metabolism and engineering improved photosynthesis, as conventional methods do not distinguish between these two fluxes. We explored widely applied gas chromatography mass spectrometry (GC-MS) metabolite profiling for C-positional fractional 13C enrichment (E13C) analyses of aspartate to differentiate within one molecule between PEPC, RUBISCO, and CBB cycle activities by 13C pulse-labeling. We validated this method using two GC-MS instruments and two prevailing chemical derivatization methods. We selectively determined E13C at each carbon position of aspartate with accuracy < 1% and precision < 2.5%. In combination with dynamic 13CO2 labeling of Synechocystis cultures, we determined PEPC activity in vivo alongside assessments of RUBISCO and CBB cycle activities. We demonstrate that RUBISCO is inactive in the dark, whereas PEPC remains active but at a lower rate than during the day. Accurate quantifications of aspartate concentrations and positional E13Cs provide molar Ci assimilation rates of photoautotrophic Synechocystis cultures. This technology can be combined with C-positional analyses of other metabolites, for example 3-phosphoglycerate, and may be adapted to characterize natural and biosynthetically engineered Ci-assimilation.","PeriodicalId":214,"journal":{"name":"New Phytologist","volume":"55 1","pages":""},"PeriodicalIF":9.4,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144701314","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}

Studying this process at the molecular level is essential to understand how plants successfully transition to autotrophic metabolism. We studied the role of the Arabidopsis class II TEOSINTE BRANCHED1, CYCLOIDEA, and PCF (TCP) transcription factor TCP10 in cotyledon de-etiolation using a variety of phenotypic, genetic, and molecular approaches. We found that TCP10 is a positive regulator of cotyledon photomorphogenesis that promotes expression of photosynthesis and cotyledon opening genes during de-etiolation, acting either directly or through the central regulator of photomorphogenic development GOLDEN2-LIKE1 (GLK1). Furthermore, TCP10 and GLK1 form a direct positive transcriptional loop that coordinates gene expression responses during de-etiolation. Besides, while light induces TCP10 expression in cotyledons of dark-germinated seedlings to trigger photomorphogenesis, retrograde signals emitted from damaged plastids prevent its expression and induce TCP10 protein degradation via the 26S proteasome, thereby preventing TCP10-induced target gene expression and cotyledon de-etiolation under these conditions. We propose that the TCP10-GLK1 transcriptional module acts as a hub that integrates light and plastid retrograde signaling pathways to fine-tune de-etiolation and ensure successful early seedling establishment according to internal and environmental stimuli.","PeriodicalId":214,"journal":{"name":"New Phytologist","volume":"33 1","pages":""},"PeriodicalIF":9.4,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144693215","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 identify Global Transcription Factor Group E proteins, GTE7 and GTE2, along with the chromatin remodeling factor INO80 Subunit 2B (IES2B), as key regulators of S homeostasis in Arabidopsis thaliana. GTE7 directly binds to the Sulfur Response Element (SURE) in the promoter of the sulfate transporter gene SULTR1;1. The SURE flanking sequence undergoes dynamic DNA methylation in response to S status, with hypermethylation under S-sufficient conditions and hypomethylation under S-deficient conditions. GTE7 and its homolog GTE2 exhibit functional redundancy in suppressing sulfate accumulation in shoots. The gte7 gte2 double mutants displayed increased sulfate accumulation in shoots and impaired root growth. IES2B, a subunit of the INO80 chromatin remodeling complex, interacts with both GTE7 and GTE2, forming a regulatory complex that modulates dynamic DNA methylation at the SULTR1;1 promoter. Disruption of IES2B abolished S-resupply-induced DNA remethylation and elevated sulfate accumulation in shoots.

This research provides a first insight into the genetic mechanisms shaping berry‐associated microbial communities. Using QTL mapping in a newly established population of 140 F1‐progeny grapevine genotypes in a complete random block design, we were able to control abiotic effects and investigate how the host genome influences grape berry‐associated bacterial and fungal communities. We identify significant associations between various microorganisms and the grape genome, including pathogenic fungi such as Botrytis spp. and fermentative yeasts such as Saccharomyces cerevisiae. Many of these taxa map to the same genetic loci associated with plant immune responses, suggesting that specific genetic loci broadly influence microbial community assembly in fruits. Our findings demonstrate that grapevine genetics significantly shape the microbiome, even under varying environmental conditions; moreover, that broad, rather than known symbiont‐specific mechanisms control microbial colonization of fruit, revealing an emergent ‘domino’ effect with implications for plant‐fungal‐bacterial interactions. We provide a framework for understanding genotype‐microbiome interactions in perennial plants, enabling future targeted experiments to establish causal relationships in microbiome recruitment and offer a potential avenue for breeding programs advancing sustainable viticulture.

Plant roots adjust their development within the soil matrix (growth, branching, root angle, and anatomical features) by integrating local environmental conditions with physiologically informed signals. These physiological responses and the adaptability of roots are commonly defined as plasticity. Although genetically determined, root plasticity is modulated by local fluctuations in water and nutrient availability, environmental changes, and soil properties as well as by the root‐associated microbiota. Roots and their vicinity are colonized by taxonomically and functionally diverse microbial species. Specific members within these communities can establish chemical communication with plants via root‐derived signals, thereby tapping into the plant's hormonal and developmental network, influencing root plasticity. Given that most root traits associated with plasticity have been discovered under axenic conditions, our knowledge of the multiple potential mechanisms by which members of the root‐associated microbiota modulate root plastic responses is still limited. In this review, we explore the recent progress in this field and identify specific avenues for future research toward advancing molecular and ecological understanding of microbial‐mediated root plasticity in terrestrial systems.","PeriodicalId":214,"journal":{"name":"New Phytologist","volume":"94 1","pages":""},"PeriodicalIF":9.4,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144670042","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 performed integrated phylostratigraphic and transcriptomic profiling across six Populus species spanning five phylogenetic clades to decipher the evolutionary dynamics of regulatory genes in the secondary vascular system. This analysis revealed that over 51% of regulatory genes originated from the most ancient phylostratum (PS1). The observed 65% gene expansion in the PS1 was driven by whole-genome duplication (WGD). Through phylotranscriptomic and gene co-expression network analysis, we found that dosage-unconstrained ohnologues from three PS1 families, MYB domain protein, NAC domain containing protein, and WRKY DNA-binding protein, have significant xylem-specific expression. We identified an ohnologue, PtoWRKY53, which forms a new transcription regulatory network in xylem via neofunctionalization. Transgenic analyses revealed that PtoWRKY53 transcriptionally represses PtoCESA3, thereby inhibiting xylem secondary wall biosynthesis and reducing poplar height (26.39%) and stem diameter (18.36%).

We show Arabidopsis catalase 2 (CAT2) is recruited to phase-separated condensates with LESION SIMULATING DISEASE1 (LSD1), a plant-specific regulator of programmed cell death, in a redox-dependent manner that regulates its intracellular localisation and activity. Using recombinant proteins, we showed that CAT2 and LSD1 form ternary complexes with the peroxisome import receptor PEX5. The ability of LSD1 to form phase-separated condensates is a property of zinc fingers 1 and 2. The interactions between all three proteins and the fluidity of the LSD1 condensates are redox-regulated. Using confocal microscopy, the in vivo trafficking of CAT2 to peroxisomes and the nuclei was shown to be redox-regulated, and LSD1 was shown to control CAT2 localisation in vivo. We propose a model whereby the redox-dependent differential accessibility of CAT2, PEX5 and LSD1 within condensates not only regulates CAT2 activity but also compartmentalisation between peroxisome, cytosol and nucleus.

In this study, we explored the use of triphenylphosphonium (TPP) as a mitochondrial‐targeting motif in plants, using Arabidopsis thaliana and several other species as models. We synthesized and applied fluorescent TPP conjugates and analysed their distribution using confocal microscopy. To evaluate functional specificity, we designed a TPP–ciprofloxacin (CFX) conjugate and compared its activity to that of free CFX in intact plants. Fluorescent TPP conjugates consistently accumulated in mitochondria, bypassing coexisting plastids. The TPP–CFX conjugate inhibited mitochondrial DNA gyrase without affecting the chloroplast isoform, slowed plant growth, elevated mitochondrial reactive oxygen species, and induced nuclear stress‐response genes, whereas free CFX perturbed both organelles. Our results establish TPP as an effective and generalizable tag for mitochondrial targeting in plant systems. This approach enables precise, organelle‐specific chemical manipulation in both model and nonmodel species, offering a new tool for plant cell biology and potential applications in precision agriculture.

We developed and tested 11 hypotheses concerning ecological drivers of interspecific variation in CT. CT showed clear patterning according to latitude, biome, taxonomic family, site climate and other leaf traits. Species with thick leaves and/or high leaf mass per area tended to have thicker cuticles, as did evergreen relative to deciduous woody species, and species from sites that during the growing season were warmer, had fewer frost days and lower wind speeds, and occurred at lower latitudes. CT-environment relationships were notably stronger among nonwoody than woody species. Heavy investment in cuticle may be disadvantaged at sites with high winds and frequent frosts for 'economic' or biomechanical reasons, or because of reduced herbivore pressure. Alternatively, cuticles may become more heavily abraded under such conditions. Robust quantification of CT-trait-environment relationships provides new insights into the multiple roles of cuticles, with additional potential use in paleo-ecological reconstruction.","PeriodicalId":214,"journal":{"name":"New Phytologist","volume":"143 1","pages":""},"PeriodicalIF":9.4,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144669347","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}
