The availability of photosynthates is a critical determinant of shoot branching (or tillering in monocots). Carbohydrates, primarily in the form of sucrose, are synthesised in actively photosynthetic leaves (sources) and transported to non-photosynthetic tissues (sinks), such as tiller buds. Glucose, fructose, sucrose and their intermediates, including trehalose-6-phosphate (Tre6P), function both as energy sources and signalling molecules. Once sucrose is transported from source to sink tissues, it is rapidly hydrolysed into hexoses, which support starch accumulation, and the formation and elongation of tiller buds (outgrowth into a branch or tiller). This review aims to summarise recent discoveries with the focus on (i) sugar synthesis, metabolism, loading and unloading; (ii) sugars as crucial signals in regulating branching; (iii) roles of sugars in mediating the environment-modulated branching; (iv) the interactions between sugars and phytohormonal pathways that influence bud outgrowth and branching. A comprehensive understanding of sugar synthesis, transport, metabolism and signalling in relation to shoot branching will aid in optimising plant architecture and ultimately contribute to enhanced crop yield.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.3,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144937515","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}

A better understanding of carbon and water fluxes for crop plants under climate change requires research based on direct canopy-scale measurements. By analysing a canopy gas exchange data set synthesised from 8 years' experimentation under semi-field conditions for the post-anthesis period of five wheat genotypes, we examined canopy carbon and water fluxes as well as carbon use efficiency (CUE) and water use efficiency (WUE) under varying environmental conditions. CUE was variable, and was negatively affected by high temperatures. Moreover, CUE responded differently to daily, daytime, and nighttime temperatures, and was most sensitive to nighttime temperatures. The response of WUE to increasing temperatures was dominated by the response of carbon fluxes, while the relative contribution of water fluxes to WUE responses increased under water deficit. WUE based on gross and net photosynthesis responded differently to environmental variables, primarily due to the differences in CUE. The findings increase our understanding of canopy carbon and water fluxes under various environmental conditions and highlight the necessity for future efforts to improve crop CUE and WUE under climate change.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.3,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144937528","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}

It has been reported that the nitrate transporters (NRTs) play critical roles for plants to survive in the nutrient-poor soils. However, the molecular mechanisms of GsNRTs in governing nitrogen (N) uptake remain largely elusive. In the present study, we identified a NRT2.4-like protein (GsNRT2.4a) as an interactor of GsSnRK1.1 kinase. Our biophysical and physiological analyses indicate that GsNRT2.4a functions as an active NRT, and GsSnRK1.1 kinase phosphorylates the Ser518 residue at the carboxyl region of GsNRT2.4a. Under N starvation conditions, the double mutant nrt2.1/nrt2.2 (2nrtm) and the quadruple mutant nrt2.1/nrt2.2/kin10/kin11 (2kinm/2nrtm) exhibited compromised growth of Arabidopsis. However, introduction of GsNRT2.4a or GsSnRK1.1/GsNRT2.4a genes into the mutants rescued their defective growth to different extent. Furthermore, we determined that GsSnRK1.1 plays a pivotal role in modulating GsNRT2.4a activity in planta by phosphorylating GsNRT2.4a at the Ser518 site, thereby collaboratively modulating plant growth under N starvation. Our findings suggest that GsNRT2.4a is essential for optimising nitrate uptake in plants, and it also elucidates a novel regulatory mechanism of GsSnRK1.1-GsNRT2.4a module for potential enhancement of nitrogen use efficiency (NUE) in plants.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.3,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144937575","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 cellular components and molecular processes for salinity sensing and stress tolerance have been extensively identified in glycophytes, but not so with halophytes. Salinity sensing requires the perception of a major soil salinity contributor, that is, sodium ions (Na+). The exact molecular mechanism or pathway for Na+ perception is still unclear. The investigations into potential Na+ sensor candidates uncovered glycosyl inositol phosphoryl ceramide (GIPC) phospholipids with direct evidence. In cells, Na+ ions are also sensed by various Non-selective cation channels (NSCCs), including the cyclic nucleotide-gated channels (CNGCs) and glutamate receptors (GLRs), and other receptor-like kinases (RLKs). This review surveyed the roles of GIPCs, CNGCs, GLRs, RLKs, including the Catharanthus roseus RLK1-like kinases, leucine-rich repeat extensins, lectin RLKs, and wall-associated kinases, as potential Na+ sensors in glycophytes and halophytes. Based on current information on these receptors, we proposed new models of Na+ sensing mechanisms in both plant types. The comparison of possible Na+ sensing mechanisms between glycophytes and halophytes might provide future research avenues for improving salt tolerance in crops.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.3,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144937531","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 unveils that inoculating Pseudomonas oryzihabitans CB24 into P. graveolens significantly alters plant's lipid dynamics, leading to increased accumulation of chloroplast glycerolipids like monogalactosyldiacylglycerol (MGDG) and sulfolipids, sulfoquinovosyldiacylglycerol (SQDG). This is achieved by enhancing precursors like UDP-6-sulfoquinovose and acetyl CoA, alongside upregulating genes such as plc, MGD1, and SQD2 crucial for glycerolipid metabolism. Glycerolipids being essential for thylakoidal membrane stability resulted in significant upregulation of genes related to antennae protein, light-harvesting complexes namely, LHCA2, LHCA1, PsaA, PetE, PetF, PsbO. P. oryzihabitans also boosted RuBisCO activity, thereby redirecting the metabolic flux towards secondary metabolism. Similarly, the upregulated expression of the DXS gene, which drives the precursors of the methylerythritol-phosphate (MEP) pathway to their end products such as monoterpenoids: geraniol and linalool, aligns with the metabolic shift from primary to secondary terpenoid biosynthesis. This transformative role of endophytic association highlights the remarkable ability of endophytes to regulate interconnected physiological processes, including improved nitrate uptake, enhanced carbon assimilation, and boosted antioxidant capacity driving significant improvements in growth, development and yield of the host plant.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.3,"publicationDate":"2025-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144937492","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}

By combining transcriptomic, metabolomic, and herbivore assays, this study aimed at providing a holistic description of maize root responses to EPNs and to assess their potential relevance for plant-herbivore interactions. EPNs triggered a dynamic shift in root metabolism, suggesting a reallocation of primary resources towards chemical defences. After 72 h, pathways related to ethylene signalling and protein folding, and turnover were downregulated, while pathways for protein export were enriched. Amino acid levels, particularly glutamate and aspartate, decreased, while glucose levels were induced. In parallel, enrichments in alpha-linolenic acid metabolism, glycan biosynthesis, and, albeit not significantly, cutin, suberine, and wax biosynthesis pathways suggested enhanced barrier functions and lipid signalling. Secondary metabolite concentrations, such as benzoxazinoids, were increased. Yet, the overall plant response remained of modest magnitude, as illustrated by a low number of differentially expressed genes exceeding 100 reads. Consistently, EPN exposure did not enhance resistance to subsequent herbivory by the root herbivores Diabrotica balteata or Diabrotica virgifera virgifera.

To further investigate the potential involvement of epigenetic remodelling, we treated lupin plants with the DNA methyltransferase (DNMT) inhibitor 5-azacytidine, which led to a disruption of total DNMT activity and impaired CR formation under phosphorus-deficient conditions. Integrated analysis of methylome and RNA-Seq highlights the methylation of CAFFEIC ACID O-METHYLTRANSFERASE 1 (COMT1), a key enzyme in melatonin synthesis, as pivotal for promoting CR formation in white lupin. Functional validation through overexpression or gene silencing of LaCOMT1 in transgenic lupin roots confirms the positive impact of LaCOMT1 on CR formation. Furthermore, melatonin application directly increases CR numbers, indicating the role of methylation-activated LaCOMT1 in promoting CR formation via melatonin synthesis.
