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.

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}

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. Those findings provide insights into the epigenomic landscape of white lupin, establishing a direct genetic link between epigenetic mechanisms and P-deficiency-induced CR formation.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.3,"publicationDate":"2025-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144937487","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}

Yellowhorn (Xanthoceras sorbifolium Bunge), an endemic species of woody oil tree in North China, has substantial developmental potential in arid and semi-arid regions. To elucidate the genetic basis of its drought response, a genome-wide association study (GWAS) of 13 leaf anatomical structure traits across 237 yellowhorn accessions was performed in this study, and 21 candidate genes that regulate leaf structural variation were identified. Among these genes, XsLTPG31, which encodes a nonspecific lipid transfer protein, was significantly induced by drought stress. Heterologous overexpression of XsLTPG31 in Arabidopsis, its transient overexpression in yellowhorn leaves, and virus-induced gene silencing (VIGS) of XsLTPG31 demonstrated that XsLTPG31 promotes the deposition of leaf epidermal wax and modulates drought resistance through facilitating the export of wax to the extracellular space. Moreover, we revealed that XsLTPG31 is directly activated by XsMYB16 via promoter binding.

Here, we characterized Parametarhizium changbaiense as a beneficial fungus that promoted mung bean growth and priming resistance to damping off caused by R. solani. Knockout of CclA, a subunit of the COMPASS complex involved in H3K4 methylation, reduced the H3K4me1 and 3 levels in P. changbaiense and diminished the fungal growth and conidiation. However, PcCclA deletion enhanced the root colonisation and further bolstered disease resistance, which correlated with intensified lignin content, lignification in the stem cells, and reactive oxygen species (ROS) scavenging ability, indicating a boost in priming defense responses. Taken together, our findings not only supported a conserved function of PcCclA in fungal growth regulation, but also demonstrated the role of PcCclA-mediated H3K4 methylation in host defense priming, which deepens the understanding of the importance of fungal epigenetic regulation in the plant-beneficial fungus interaction.

However, advances in proteomics have revealed that non-histone proteins also undergo lysine acetylation, prompting increasing efforts to elucidate the underlying mechanisms and functions of this posttranslational modifications. This review provides a comprehensive analysis of acetyl-lysine proteome (acetylome) studies during plant interaction with pathogens (including fungi, bacteria and viruses). By highlighting the significance of lysine acetylation in non-histone proteins, these studies offer valuable insights into potential new targets for lysine acetylation in plant immunity. We further examine the roles of plant KATs and KDACs, as well as pathogen-derived KATs, emphasizing the different types of lysine acetylation in non-histone proteins. In particular, we explore how bacterial effectors, which mimic KAT activity, acetylate lysine residues in non-histone proteins to modulate plant immunity. Additionally, we discuss on emerging molecular mechanisms involving plant KATs and KDACs that finely regulate immune responses, particularly within the jasmonic acid signalling pathway. These findings open new perspectives for future research on this posttranslational regulation within the context of plant immunity.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.3,"publicationDate":"2025-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144937503","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}
