We previously identified the receptor-like kinase PSKR1/ALR1 (ALR1) in Arabidopsis as a receptor that senses phytotoxic aluminium (Al) ions, which cause severe crop yield loss and forest decline on acidic soils widely distributed over the world. Here we further show that the phosphorylation status of specific Ser residues in ALR1(Ser696/698) controls plant Al-sensing ability. ALR1(Ser696/698) phosphorylation levels are rapidly reduced by Al ions, and the dephosphorylation promotes the interaction and inter-phosphorylation of ALR1 and the BAK1 coreceptor, thereby activating STOP1-dependent Al signalling and resistance. We next identify a clade of PP2C-type phosphatases (PP2CH1 and PP2CH2) that mediate the dephosphorylation of ALR1(Ser696/698). We show that Al ions rapidly increase the protein accumulation of PP2CH1/2 and promote their interaction with ALR1. The lack of both PP2CHs notably increases the phosphorylation levels of ALR1(Ser696/698), therefore reducing the strength of Al signalling. Additionally, we found a receptor-like cytoplasmic kinase, PBL27, responsible for phosphorylating ALR1(Ser696/698) and playing a negative role in the regulation of ALR1-mediated Al signalling. These findings uncover a phosphatase/kinase-mediated phosphorylation switching mechanism of ALR1 that controls plant Al-sensing ability, providing insights into ion-sensing mechanisms in living organisms.","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"38 1","pages":""},"PeriodicalIF":18.0,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143819163","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}

Unlike sweet oranges, sour oranges exhibited high genetic and metabolic diversity and high variation in susceptibility to citrus canker. Shared heterozygous genomic segments between sour and sweet oranges traced their common parentage to mandarin and pummelo lineages. Phased telomere-to-telomere genomes of sweet and sour oranges were generated, and their two haplotype genomes show close relatedness to the mandarin and pummelo genomes, respectively. Integrative kinship analysis based on nuclear and chloroplast genomes of the citrus population enabled Liu et al. to deduce that sweet orange originated by hybridization between an ancient mother sour orange and a father Ponkan mandarin, and that sour orange probably originated from another more ancient cross between wild mandarin and pummelo.To introduce genetic diversity, the researchers, according to their origin model, crossed a canker-resistant sour orange accession with a Ponkan mandarin line. Embryo rescue yielded 892 hybrids with diverse genetic and metabolomic compositions. Three hybrids displayed high genetic and phenotypic similarity to commercial sweet oranges. These artificial sweet oranges support this model of origin.","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"246 1","pages":""},"PeriodicalIF":18.0,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143819358","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}

These Aux/IAA proteins are then marked for degradation by ubiquitination. As they are degraded, they stop repressing ARF transcription factors, which are then free to activate downstream auxin genes. This model of signalling by degradation of transcriptional repressors was found to be conserved in several other hormone signalling pathways.It was recently shown by the same team that TIR1 and AFBs have an unexpected auxin-induced adenylate cyclase (AC) activity that arises from a small domain near their C terminus, and that this activity producing cAMP is needed for root growth response to auxin. Now, the authors perform a set of clever experiments, including the use of an engineered orthogonal TIR1–auxin pair that works without interference from the constant endogenous auxin signalling background, the mutational uncoupling of TIR1 AC activity from its ubiquitin ligase activity, abolishing auxin-induced cAMP production but still allowing the degradation of Aux/IAA proteins, various auxin reporters, and many mutants and transgenic lines. Reading this study feels like observing a watchmaker digging into the precise clockwork mechanism of this signalling pathway, removing or replacing one cog at a time to see what happens.","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"24 1","pages":""},"PeriodicalIF":18.0,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143805680","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}

Across eukaryotes, the mechanism of action and functional significance of several variants of core histones are well known except those of histone H4. Here we show that a variant of H4 (H4.V) expressing tissue-specifically among Oryza members mediated specific epigenetic changes contributing to salt tolerance. H4.V was incorporated into specific heterochromatic sites, where it blocked the deposition of active histone marks. Stress-dependent redistribution of H4.V enabled the incorporation of acetylated H4 lysine 5 (H4K5ac) in the gene bodies. The misexpression of H4.V led to defects in reproductive development and in mounting salt stress responses. H4.V formed homotypic nucleosomes and mediated these alterations by conferring distinct molecular properties to the nucleosomes, as seen with cryo electron microscopy structures and biochemical assays. These results reveal not only an H4 variant among plants but also a chromatin regulation that might have contributed to the adaptation of semi-aquatic Oryza members.","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"35 1","pages":""},"PeriodicalIF":18.0,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143797834","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 narrow genetic foundation of cultivated roses limits their further improvement. Wild Rosa species harbour vast genetic diversity, yet their utilization is impeded by taxonomic confusion. Here we generated a phased and gap-free reference genome of Rosa persica for phylogenetic and population genomic analyses of a large collection of Rosa samples. The robust nuclear and plastid phylogenies support most of the morphology-based traditional taxonomy of Rosa. Population genomic analyses disclosed potential genetic exchanges among sections, indicating the northwest and southwest of China as two independent centres of diversity for Rosa. Analyses of domestication traits provide insights into selection processes related to flower colour, fragrance, double flower and resistance. This study provides a comprehensive understanding of rose domestication and lays a solid foundation for future re-domestication and innovative breeding efforts using wild resources.","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"108 1","pages":""},"PeriodicalIF":18.0,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143775687","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}

New surface cells are exposed during abscission, by which leaves, fruits, flowers and seeds are shed. Recent work has shown that nonepidermal residuum cells (RECs) can accumulate a protective cuticle layer after abscission, implying the potential de novo specification of epidermal cells by transdifferentiation. However, it remains unknown how this process occurs and what advantage this mechanism may offer over the other surface protection alternative, the wound healing pathways. Here we followed this transdifferentiation process with single-cell RNA sequencing analysis of RECs, showing that nonepidermal RECs transdifferentiate into epidermal cells through three distinct stages. During this vulnerable process, which involves a transient period when the protective layer is not yet formed, stress genes that protect the plant from environmental exposure are expressed before epidermis formation, ultimately facilitating cuticle development. We identify a central role for the transcription factor MYB74 in directing the transdifferentiation. In contrast to alternative protective mechanisms, our results suggest that de novo epidermal specification supports the subsequent growth of fruit at the abscission site. Altogether, we reveal a developmental programme by which plants use a transdifferentiation pathway to protect the plant while promoting growth.","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"21 1","pages":""},"PeriodicalIF":18.0,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143766452","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}
