Here, we generated a high-resolution single-cell transcriptomic atlas of Arabidopsis anther development, profiling 66,864 cells from early lineage specification through pollen maturation. We resolved major anther cell types and identified an early L2-derived intermediate population, termed the archesporial-derived state (Ar-d), marked by REM22, ER/ERL1/2, SPL/NZZ, and BAM1. Although classical anatomical studies define archesporial cells, primary sporogenous cells, primary parietal cells, and secondary parietal derivatives based on developmental position and inferred lineage relationships, our analysis showed that these early L2-derived intermediates remain globally similar, forming a shared progenitor-like transcriptional state before lineage stabilization. Trajectory reconstruction, RNA velocity, and module analyses revealed that germline and somatic trajectories first emerge through restricted branch-biased transcriptional programs, which are later amplified into robust lineage-specific identities. Mutant single-cell analyses defined two regulatory steps: SPL/NZZ establishes early branch-associated transcriptional programs within the Ar-d state, whereas EMS1 stabilizes the somatic/tapetal trajectory and restricts inappropriate enrichment of germline-associated states. Lineage-resolved analyses further defined maturation programs in germline, tapetum, middle layer, and endothecium cells, and identified LBD transcription factors required for normal pollen development. Together, our study reveals a cryptic mode of anther fate priming in which shared early L2-derived intermediates progressively transform limited branch-biased transcriptional programs into distinct reproductive and somatic cell identities through SPL-dependent priming and EMS1-dependent somatic/tapetal stabilization.","PeriodicalId":501012,"journal":{"name":"The Plant Cell","volume":"35 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148894510","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most cloned plant Resistance (R) genes encode NLR immune receptors. NLR genes are often found in clusters of paralogs with sequence and copy number variation; whether these NLR clusters evolve in response to single or multiple pathogens has been unclear. We report here the isolation of a Phytophthora capsici resistance gene, Rpc2, along with a novel P. infestans resistance gene, Rpi-amr5, from two Solanum americanum accessions. These orthologous genes reside in the Rpi-amr1 cluster, which has previously been associated with resistance to P. infestans. By screening RXLR effector libraries of P. infestans and P. capsici, we identified multiple effectors recognised by both NLRs. Our findings highlight the complexity of NLR clusters and evolution driven by interactions with multiple pathogens. This work will underpin efforts to elevate resistance against Phytophthora pathogens and enhances our understanding of NLR evolution.","PeriodicalId":501012,"journal":{"name":"The Plant Cell","volume":"82 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148894509","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the regulatory mechanism governing LNP activity remains largely unknown. Here, we report the characterization of the rice oskish mutant, which exhibits aberrant aggregation of ER tubules and defective ER exit of seed storage proteins. OsKish is an ER-localized small protein that physically interacts with both OsLNPs and RHD3-like (RHD3L) protein. OsKish stabilizes OsLNPs by suppressing their auto-ubiquitination; concomitantly, OsKish attenuates the membrane fusion activity of RHD3L possibly by inhibiting its oligomerization.

In cyanobacteria, its deficiency affects growth, phycobiliprotein biosynthesis, and leads to degradation of phycobilisomes (PBSs). While the biosynthesis genes of phycobiliprotein are regulated by strong promoters, the molecular mechanisms underlying their regulation in response to nitrogen deficiency remain largely unknown. Using non-diazotrophic cyanobacterium Synechococcus elongatus PCC 7942 as a model system, we identified a novel PBS biosynthesis regulator, a small helix-loop-helix protein, designated the Nitrogen Starvation Regulator of the cpc Operon (NsrC). The nsrC gene was transcriptionally activated by nitrogen starvation. The nsrC knockout delayed cell chlorosis during nitrogen starvation, increased oxygen evolution, and significantly elevated PBS protein content. NsrC directly bound to the promoter region of the cpc operon, inhibiting the expression of PBS structural genes, including cpcA and cpcB. Moreover, there was an interaction between NsrC and PII, a signal transduction protein sensing the carbon/nitrogen balance. The binding of NsrC to PII was modulated by the metabolite 2-oxoglutarate (2-OG), which accumulates under nitrogen starvation conditions. Elevated 2-OG levels promoted PII-NsrC complex dissociation, facilitating NsrC binding to the cpc operon and inhibiting PBS expression. Moreover, NsrC is conserved and widely distributed in cyanobacteria and red algae that retain the PBS light-harvesting apparatus; however, it exhibits structural and functional divergence when compared to those found in diatoms and brown algae. Overall, our results showed that the PII-NsrC axis regulates PBS biosynthesis, offering insights into the adaptive mechanisms of cyanobacteria and red algae under nitrogen starvation.","PeriodicalId":501012,"journal":{"name":"The Plant Cell","volume":"10 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148806411","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we found that mutation of DECREASED IN DNA METHYLATION 1 (DDM1) in soybean leads to genome-wide chromatin homogenization, characterized by a loosening of heterochromatin and a tightening of euchromatin. This remodeling triggers two distinct molecular pathways: in heterochromatin, increased release of small RNAs activates the non-canonical RdDM pathway; while in euchromatin, transposable elements (TEs) are enriched with H3K9me2 modifications, which in turn activate the CMT2 pathway. Together, these pathways drive a pronounced burst of CHH methylation at the whole genome level. This epigenetic remodeling correlates with massive transcriptional dysregulation, upregulating stress responses and downregulating photosynthesis, linking local H3K9me2 changes on TEs, ultimately leading to severe phenotypes. Our findings reveal a unique, bidirectional pathway for CHH regulation in plants with complex chromatin states remodeling.","PeriodicalId":501012,"journal":{"name":"The Plant Cell","volume":"36 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148768126","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Carbon flux measurements in intact Arabidopsis leaves using an MS2 isotopologue methodology revealed unexpected dynamics between chorismate and isochorismate pools. 13CO2 labeling kinetics point to chloroplast-derived shikimate as a major bifurcation point, with approximately one third diverted from the chloroplast. In contrast, the small pool of chorismate was mostly chloroplast-localized and turned over rapidly, reaching more than 70% labeling within minutes. Isochorismate, a precursor to salicylic acid (SA) in the Brassicales, was present at 50-fold molar excess over chorismate but labeled more slowly and appeared primarily extra-chloroplastic. Total isochorismate declined by 90% in the Arabidopsis enhanced disease susceptibility mutant, which lacks the isochorismate exporter. Non-aqueous fractionation further supported a primarily chloroplast-localized chorismate pool but extra-plastidic isochorismate. Populus trichocarpa and Nicotiana benthamiana leaves contained chorismate but only trace isochorismate, consistent with use of the benzoyl-CoA route to SA. Carbon commitment calculations indicated that one third of the total chorismate pool in Arabidopsis leaves is diverted to isochorismate. Global leaf calculations based on elemental analysis-isotope ratio mass spectrometry and targeted isotope recovery indicate that only 0.03% of total assimilated carbon (5.27 pmol·mg-1 D.W.·min-1) enters the shikimate pathway in photosynthetic tissue of Arabidopsis thaliana. For comparison ∼0.05% (7.75 pmol·mg-1 D.W.·min-1) enters the 2-C-methyl-D-erythritol 4-phosphate pathway, which provides precursors for photosynthetic pigments and electron carriers. The compartmentalization and turnover dynamics of shikimate, chorismate, and isochorismate suggest continuous demand for aromatic precursors in mesophyll tissue is comparable to demand for MEP-pathway derived pigments.","PeriodicalId":501012,"journal":{"name":"The Plant Cell","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148768130","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the mechanism by which Ehd1 transmits heading signals to Hd3a and the accurate regulation of Hd3a expression remains unclear. Here, we found that OsWOX13 functions as a signal transducer from Ehd1 to Hd3a for the accurate regulation of rice heading date. Ehd1 can directly bind to the OsWOX13 promoter, OsWOX13 in turn binds to the Hd3a promoter to activate its expression. OsWOX13 interacts with Hd3a to inhibit OsWOX13-mediated activation of Hd3a expression, that precisely controls Hd3a levels. Meanwhile, late-heading phenotypes were observed in the ehd1, Oswox13, Oswox13 ehd1, hd3a, and Oswox13 hd3a, demonstrating that Ehd1, OsWOX13, and Hd3a coordinately regulate rice heading date. Furthermore, OsWOX13 can be divided into two haplotypes, Hap-T and Hap-C. Ehd1 elevated OsWOX13 expression in Hap-T compared with Hap-C. Longjing 31T-C (carrying Hap-C) exhibited later heading dates than Longjing 31 (carrying Hap-T). Rice varieties carrying the Hap-T are predominantly cultivated in high-latitude regions.

A miRNA165/166-resistant, gain-of-function lf1 mutant displays an enlarged leaf angle driven by elongated adaxial parenchymal cells and diminished abaxial sclerenchyma. At the transcriptional level, the BR-activated transcription factor OsBZR1 directly induces LF1, which in turn upregulates OsOFP8, forming an OsBZR1-LF1-OsOFP8 hierarchical transcriptional cascade that mediates BR signaling to regulate leaf angle development. At the post-translational level, LF1 protein stability is fine-tuned by reciprocal post-translational modifications, wherein OsMAPK6-mediated phosphorylation at Thr148 promotes LF1 accumulation and transcriptional activity, directly counteracting its ubiquitination and degradation by the APC/CTAD1 complex. Genetic analyses demonstrate that LF1, OsMAPK6, and TAD1 function in a common pathway to regulate leaf angle development.

While PME-mediated removal of methyl groups increases pectin susceptibility to enzymatic degradation and facilitates wall remodeling, this process is suppressed by PMEIs to strengthen the wall, preventing pathogen invasion. How biotrophic pathogens overcome this inhibitory defense remains unclear. Here, we demonstrate how N-glycosylation serves as a post-translational mechanism that pre-shapes a conserved smut effector, directing its adaptation toward a host-specific PMEI to facilitate colonization. We identify the Ustilago maydis N-glycosylated effector Nge1, which interacts with two host inhibitors, PMEI45 and PMEI46, to suppress their inhibitory function. This release of PME activity leads to highly demethylated pectin in the host cell wall that is prone to degradation, likely driving the cell wall loosening favored by pathogens. Crucially, we show that N-glycosylation of Nge1 is essential for its interaction with PMEI45, whereas the interaction with PMEI46 is glycosylation-independent. Engineering N-glycosylation sites into a naturally non-glycosylated Nge1 ortholog restored its ability to neutralize host PMEIs and functionally complement the U. maydis Δnge1 mutant. Our findings reveal that smut fungi utilize post-translational glycan modifications to fine-tune effector specificity, allowing them to overcome host-adapted PMEIs and manipulate plant cell wall dynamics in an ongoing plant-fungal interplay.","PeriodicalId":501012,"journal":{"name":"The Plant Cell","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148703455","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
