However, not everything translates from Arabidopsis to crops and other plants. Here, a group of experts consider instances where translation has been lost and why such translation is not possible or is challenging. First, despite great efforts, floral dip transformation has not succeeded in other species outside Brassicaceae. Second, due to gene duplications and losses throughout evolution, it can be complex to establish which genes are orthologs of Arabidopsis genes. Third, during evolution Arabidopsis has lost arbuscular mycorrhizal symbiosis. Fourth, other plants have evolved specialized cell types that are not present in Arabidopsis. Fifth, similarly, C4 photosynthesis cannot be studied in Arabidopsis, which is a C3 plant. Sixth, many other plant species have larger genomes, which has given rise to innovations in transcriptional regulation that are not present in Arabidopsis. Seventh, phenotypes such as acclimation to water stress can be challenging to translate due to different measurement strategies. And eighth, while the circadian oscillator is conserved, there are important nuances in the roles of circadian regulators in crop plants. A key theme emerging across these vignettes is that even when translation is lost, insights can still be gained through comparison with Arabidopsis.","PeriodicalId":501012,"journal":{"name":"The Plant Cell","volume":"129 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143992089","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}

Among these effectors, Pathogenicity toward Weeping Lovegrass 2 (Pwl2) was originally identified as a host specificity determinant for the infection of weeping lovegrass (Eragrostis curvula) and is also recognized by the barley (Hordeum vulgare) Mla3 resistance protein. However, the biological activity of Pwl2 remains unknown. Here, we showed that the Pmk1 MAP kinase regulates PWL2 expression during the cell-to-cell movement of M. oryzae at plasmodesmata-containing pit fields. Consistent with this finding, we provided evidence that Pwl2 binds to the barley heavy metal-binding isoprenylated protein HIPP43, which results in HIPP43 displacement from plasmodesmata. Transgenic barley lines overexpressing PWL2 or HIPP43 exhibit attenuated immune responses and increased disease susceptibility. In contrast, a Pwl2SNDEYWY variant which does not interact with HIPP43 fails to alter the plasmodesmata localization of HIPP43. Targeted deletion of three PWL2 copies in M. oryzae resulted in a Δpwl2 mutant showing gain of virulence toward weeping lovegrass and barley Mla3 lines, but reduced blast disease severity on susceptible host plants. Taken together, our results provide evidence that Pwl2 is a virulence factor that suppresses host immunity by perturbing the plasmodesmatal deployment of HIPP43.","PeriodicalId":501012,"journal":{"name":"The Plant Cell","volume":"70 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143926423","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}

Sex ratio in many homosporous species is environmentally established by the secretion of antheridiogen from female/hermaphrodite gametophytes. Nearby undetermined gametophytes perceive antheridiogen, which induces male development. In the fern Ceratopteris richardii (Ceratopteris), hermaphroditic (her) mutants develop as hermaphrodites even in the presence of antheridiogen. Modern sequencing and genomic tools make the molecular identification of mutants in the 11-Gbp genome of this fern possible. We mapped 2 linked mutants, her7-14 and her7-19, to the same 16-Mbp interval on chromosome 29 of the Ceratopteris genome. An ortholog of the receptor kinase gene BRASSINOSTEROID INSENSITIVE 1 (BRI1) within this interval encoded a deletion mutation in her7-14 and a missense mutation in her7-19. Three other linked her mutants encoded missense mutations in the same gene, which we name HER7. Consistent with a function as a receptor kinase, HER7-GFP fusion protein localized to the plasma membrane and cytoplasm. Analysis of gene expression showed that brassinosteroid biosynthesis was upregulated in hermaphrodites compared with male gametophytes. Our work demonstrates that HER7 is required for sex determination in Ceratopteris and opens avenues for studying the evolution of antheridiogen systems.","PeriodicalId":501012,"journal":{"name":"The Plant Cell","volume":"39 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143932521","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}

It involves transcriptomic reprogramming of numerous genes, each having a small contribution to plant immunity. Despite the broad-spectrum nature of QDR, the evolution of its underlying transcriptome reprogramming remains largely uncharacterized. Here, we analyzed global gene expression in response to the necrotrophic fungus Sclerotinia sclerotiorum in 23 Arabidopsis (Arabidopsis thaliana) accessions of diverse origin and contrasting QDR phenotypes. Over half of the species pan-transcriptome displayed local responses to S. sclerotiorum, with global reprogramming patterns incongruent with accession phylogeny. Due to frequent small-amplitude variations, only ∼11% of responsive genes were common across all accessions, defining a core transcriptome enriched in highly-responsive genes. Co-expression and correlation analyses showed that QDR phenotypes result from the integration of the expression of numerous genes. Promoter sequence comparisons revealed that variation in DNA-binding sites within cis-regulatory regions contributes to gene expression rewiring. Finally, transcriptome-phenotype maps revealed abundant neutral networks connecting diverse QDR transcriptomes with no loss of resistance, hallmarks of robust and evolvable traits. This navigability associated with regulatory variation in core genes highlights their role in QDR evolvability. This work provides insights into the evolution of complex immune responses, informing models for plant disease dynamics.","PeriodicalId":501012,"journal":{"name":"The Plant Cell","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143926412","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}

Theanine levels are high in new tea plant (Camellia sinensis) shoots that arise during early spring, but then significantly decrease in late spring, causing a rapid decline in the quality of green tea processed from the late-spring harvest. However, the molecular mechanisms underlying this seasonal decrease in theanine levels remain unknown. In a previous genetic screen, we identified the YFR045W yeast mutant that displayed a hypersensitivity to theanine feeding due to enhanced theanine accumulation. YFR045W encodes a putative mitochondrial carrier and was designated Theanine Hypersensitive 1 (THS1). Expression of CsTHS1, the functional homolog of THS1 in tea plants, rescued this yeast mutant phenotype. Importantly, CsTHS1 expression is induced in late-spring new shoots, and CsTHS1 exhibits a high affinity for theanine. Yeast mitochondria expressing CsTHS1 demonstrate increased theanine transport activity, and recombinant CsTHS1 proteo-liposomes can also transport theanine. Additionally, CsTHS1 overexpression or repression in new tea shoots significantly decreased or increased theanine accumulation, respectively. Our findings establish a relationship between CsTHS1-mediated theanine transport into mitochondria and the observed reduction in theanine accumulation in the late-spring new tea shoots. Our study supports a mechanism whereby CsTHS1 mediates theanine entry into mitochondria for degradation by the mitochondria-localized γ-glutamyl transpeptidase (CsGGT2).","PeriodicalId":501012,"journal":{"name":"The Plant Cell","volume":"24 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143910474","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}

Here, we identified a signaling pathway that governs the wound-induced regeneration of Arabidopsis (Arabidopsis thaliana) roots, highlighting a key role for the peptide RAPID ALKALINIZATION FACTOR33 (RALF33) and its receptor FERONIA (FER). Wounding triggers RALF33 accumulation, which promotes root regeneration, and fer mutants exhibit an enhanced regeneration capacity. The accumulated RALF33 hinders FER-mediated phosphorylation of the transcriptional co-repressor TOPLESS-RELATED4 (TPR4), impairing TPR4 nuclear localization and inhibiting its interaction with the transcription factor ETHYLENE RESPONSE FACTOR115 (ERF115). ERF115 has greater transcriptional activity when it is not associated with TPR4. Disrupting the FER-targeted phosphorylation sites in TPR4 via alanine substitutions (TPR4A) resulted in TPR4 mislocalization and impaired binding of TPR4A to ERF115. Our findings reveal that RALF33–FER–TPR4–ERF115 compose a key signaling cascade that orchestrates wound-induced regeneration, providing valuable insights into the regulation of plant regenerative responses.","PeriodicalId":501012,"journal":{"name":"The Plant Cell","volume":"19 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143910546","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}
