However, the genetic network underlying this trait remains unclear. Therefore, the present study investigated the changes in apple fruit at different stages of postharvest storage using a combination of transcriptomic and metabolomic analyses. With prolonged storage, we detected a significant increase in two metabolites, d-galacturonic acid (d-GalUA) and d-glucuronic acid (d-GlcA), which are associated with a key class 1 non-symbiotic haemoglobin (MdHb1). We innovatively found that MdHb1 regulates fruit softening by catalysing the conversion from protopectin to water-soluble pectin. Biochemical analysis demonstrated that MdMYB2/MdNAC14/MdNTL9 transcription factors directly bind to the MdHb1 promoter to activate its transcriptional expression and promote fruit softening. Further injection experiments in apple fruit and histological as well as transmission electron microscopy analyses of the fruit samples revealed that d-GalUA and d-GlcA reduce the transcription of MdHb1, or through the MdMYB2/MdNAC14/MdNTL9-MdHb1 regulatory module, thereby delaying fruit softening. Our study provides novel insights into the role of two important metabolites, d-GalUA and d-GlcA, in the regulation of MdHb1-mediated fruit softening in apples.","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"4 1","pages":""},"PeriodicalIF":18.0,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143841319","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 closed forest paradigm, emphasizing dense, continuous canopy cover, dominates current forest management strategies. However, this approach may overlook the historical role of large herbivores in maintaining semi-open forest conditions. Here we analyse the light and herbivory preferences of 917 native temperate forest plant species across central and western Europe, comparing these preferences with light availability in untouched closed-canopy forests and pasture woodlands. Plant species are 0.1–10 Myr old, with phylogenetic conservatism in habitat affinities (niche optima); thus, their distribution reflects long-term environmental states. We found that most temperate forest plants favour heterogeneous, semi-open-canopy conditions associated with high large-herbivore impacts, rather than uniform closed-canopy environments. On the basis of Red List criteria, high-affinity forest plants associated with higher herbivory and lower herbaceous biomass face higher extinction risk, indicating that low large-herbivore densities drive extinctions in present-day forests. These results align with palaeoecological evidence and high biodiversity in modern open woodlands, suggesting that closed-canopy dominance is a recent consequence of human-driven herbivore loss. Recognizing the role of large herbivores in maintaining semi-open vegetation offers new insights for biodiversity conservation and challenges the suitability of closed-canopy models in forest management.","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"26 1","pages":""},"PeriodicalIF":18.0,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143827675","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}

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}
