Valine-glutamine (VQ) motif-containing proteins function as transcriptional regulators of plant growth and stress responses.

Here, MdVQ17 was identified as a salt-responsive gene that negatively regulates salt tolerance in apple plants by increasing the Na+/K+ ratio and suppressing reactive oxygen species (ROS) scavenging under salt stress. MdWRKY100, a WRKY transcription factor that enhances apple salt tolerance, was identified as an MdVQ17-interacting protein. MdWRKY100 directly bound to the Arabidopsis K⁺ TRANSPORTER 1-LIKe (MdAKT1-like) and PEROXIDASE 57 (MdPER57) promoters, activating their transcription. MdVQ17 inhibited the binding and transcriptional activation activity of MdWRKY100 at these promoters, thereby suppressing MdWRKY100-mediated regulation of Na+/K+ homeostasis and antioxidant enzyme activity. MdVQ37, another MdWRKY100-interacting VQ protein, modulated the MdWRKY100-mediated salt response through a similar mechanism. Overall, these findings reveal that the MdVQ17/MdVQ37-MdWRKY100 module co-regulates Na+/K+ homeostasis and ROS scavenging by modulating MdAKT1-like and MdPER57 expression, providing insights into how the VQ-WRKY complex influences salt tolerance in apple.","PeriodicalId":20101,"journal":{"name":"Plant Physiology","volume":"17 1","pages":""},"PeriodicalIF":7.4,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145194729","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}

Thus, increasing photosynthetic efficiency is a promising approach for boosting plant growth and yield. However, the genetic basis of photosynthesis in perennial woody plants remains largely unknown, and the causative alleles warrant comprehensive investigation. Here, we performed a genome-wide association study (GWAS) on photosynthetic traits in a natural population of Chinese white poplar (Populus tomentosa). We identified inflorescence and root apices receptor-like kinase-interacting protein (IRKI) as a causative gene of photosynthesis that is significantly associated with the activity of rubisco activase (Rca). The seventh leaves of PtoIRKI-OE plants exhibited a 27.77% increase in net photosynthetic rate (Pn), a 31.42% rise in starch content, and a 16.83% expansion in leaf area compared to wild-type plants, whereas ptoirki-KD plants displayed opposite phenotypes. Further analyses indicated that PtoIRKI interacted with PtoRca to enhance Rca activity, leading to increases in the activation state of ribulose bisphosphate carboxylase oxygenase (rubisco) and photosynthetic efficiency. Importantly, we identified an elite haplotype, PtoIRKIhap2, which exhibited higher PtoIRKI expression and Pn than PtoIRKIhap1. Finally, we found that homeodomain-leucine zipper protein 1 (PtoHB1) specifically bound to the PtoIRKIhap2 promoter, thereby promoting PtoIRKI expression and photosynthetic efficiency, as validated by integrating machine learning models and molecular experiments. Our results shed light on the molecular mechanism through which PtoIRKI modulates photosynthetic efficiency. We also provide an excellent haplotype module, PtoHB1-PtoIRKIhap2-PtoRca, that can be used to improve the photosynthesis of woody plants via molecular breeding.","PeriodicalId":20101,"journal":{"name":"Plant Physiology","volume":"114 1","pages":""},"PeriodicalIF":7.4,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145188685","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 indica-japonica intersubspecific hybrids offer a 20-30% yield increase over indica-indica hybrids, the mechanisms underlying intersubspecific heterosis remain poorly explored. Here, we sequenced and phenotyped three pairwise crosses and their derived populations from representative japonica and indica varieties. Intersubspecific hybrids exhibited stronger heterosis and superior biomass than intrasubspecific hybrids. Transcriptomic analysis demonstrated that brassinosteroid signaling and flowering-promoting genes are up-regulated in intrasubspecific hybrids to accelerate growth, while intersubspecific hybrids display enhanced tillering capacity and yield potential through elevated transcriptional activity and gene expression related to nitrogen use efficiency. Genome-wide allele-specific expression analysis highlighted the regulatory impact of parental genomic divergence on hybrid gene expression, particularly through promoter variations affecting genes involved in flowering, tillering, pollen fertility, and stress response. QTL mapping revealed a greater number of loci associated with heterosis in intersubspecific hybrids than in intrasubspecific hybrids, particularly for spikelets per panicle and plant height, where the Nipponbare allele and indica alleles function as advantageous alleles across distinct QTLs; their synergistic interactions collectively drive the heterosis between subspecies. Our study reveals that parental genetic diversity combined with dominant expression patterns collectively drives heterosis, providing valuable insights for optimizing intersubspecific hybrid rice breeding to enhance yield and agricultural sustainability.","PeriodicalId":20101,"journal":{"name":"Plant Physiology","volume":"17 1","pages":""},"PeriodicalIF":7.4,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145188773","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}

LR development is characterized by the establishment of an auxin maximum at the lateral root primordium (LRP); however, the regulatory mechanisms underlying this process remain poorly understood. In Arabidopsis (Arabidopsis thaliana), FORMATION OF APLOID AND BINUCLEATE CELLS1 (FAB1) encodes a lipid kinase responsible for biosynthesizing phosphatidylinositol 3,5-bisphosphate. Our findings show that auxin induces FAB1 expression through AUXIN RESPONSE FACTOR7/19 (ARF7/19). In turn, FAB1 modulates the auxin maximum at the LRP tip by regulating clathrin-mediated endocytosis of the PIN-FORMED (PIN) auxin efflux carriers, forming a previously uncharacterized auxin-induced feedback loop during LR development. Loss of FAB1 function markedly increases LR number, while FAB1 overexpression suppresses LR formation. Diminished FAB1 activity leads to less clathrin accumulation at the plasma membrane (PM), limited endocytosis, and greater PIN3 retention at the LRP PM, thereby enhancing auxin flow toward LRP tips and promoting emergence. These results identify FAB1 as a negative regulator of lateral root development that fine-tunes auxin transport to facilitate organ emergence.","PeriodicalId":20101,"journal":{"name":"Plant Physiology","volume":"91 1","pages":""},"PeriodicalIF":7.4,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145194728","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 identification of acylplastoquinol (APQ) as the major component of the \"TAG fraction\" obtained through thin-layer chromatography (TLC) has raised questions about the actual presence of TAG in cyanobacteria. To address concerns regarding potential chemical and biological contamination in the detection of TAG in cyanobacteria, we developed 1D- and 2D-TLC methods to separate submicromole quantities of TAG and APQ from Synechocystis cells. Both compounds were convincingly identified using NMR and LC/MS. TAG levels depended upon culture conditions. Well-aerated cyanobacterial cultures exhibited minimal TAG levels, while TAG accumulation reached approximately 1% of total lipids in static or slowly swirled senescing cultures, where photosynthetic activity had declined substantially. Under these conditions, we observed numerous lipid globules, approximately 72 nm in diameter, located at the periphery of the cells.

It is also conceivable that RNA editing serves a regulatory function, as proteins can be translated from partially unedited transcripts. In this study, we characterize proteins derived from such mitochondrial transcripts. To enrich these proteins, we use an Arabidopsis multiple organellar RNA editing factor 3 (MORF3) mutant, which exhibits reduced RNA editing at numerous specific sites. Despite developmental delays, the mutant plants remain fertile. Physiological and biochemical analyses reveal that complex I of the respiratory chain is particularly affected in the mutants. Consistent with these findings, a shotgun proteomic analysis identified proteins originating from partially unedited NADH dehydrogenase subunit 2 (nad2) and nad7 transcripts. Complexome profiling revealed that these proteins integrate into the holo-complex and, to a lesser extent, into the supercomplex formed by complex I and dimeric complex III. Concurrently, known assembly intermediates of complex I are enriched in the mutant. We demonstrate that the disruption of complex I assembly is caused by the absence of editing at specific sites in transcripts encoding the subunits Nad3 and Nad4L.
