However, the developmental mechanisms underlying inferior ovary formation remain largely unknown. Comparative spatial transcriptome mapping and cell lineage reconstructions in developing floral buds of cucumber and tomato, which have inferior and superior ovaries, respectively, revealed that inferior ovaries develop from accelerated receptacle growth resulting from the continuous activity of meristematic stems cells at the base of the cucumber floral organs. Genetic knockout of a receptacle-specific KNOX1 transcription factor in cucumber caused arrest in receptacle growth and yielded bisexual flowers with superior ovaries similar to those of tomato. Here we provide developmental and mechanistic insights into inferior ovary formation and sex determination in cucurbits.","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"75 1","pages":""},"PeriodicalIF":18.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143745313","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}

Metabolic engineering is also the basis for producing high-value plant products such as pharmaceuticals, biofuels and industrial biochemicals. An inherent problem for such engineering endeavours is the tendency to view metabolism as a series of distinct metabolic pathways—glycolysis, the tricarboxylic acid cycle, the Calvin–Benson cycle and so on. While these canonical pathways may represent a dominant or frequently occurring flux mode, systematic analyses of metabolism via computational modelling have emphasized the inherent flexibility of the metabolic network to carry flux distributions that are distinct from the canonical pathways. Recent experimental estimates of metabolic network fluxes using 13C-labelling approaches have revealed numerous instances in which non-canonical pathways occur under different conditions and in different tissues. In this Review, we bring these non-canonical pathways to the fore, summarizing the evidence for their occurrence and the context in which they operate. We also emphasize the importance of non-canonical pathways for metabolic engineering. We argue that the introduction of a high-flux pathway to a desired metabolic product will, by necessity, require non-canonical supporting fluxes in central metabolism to provide the necessary carbon skeletons, energy and reducing power. We illustrate this using the overproduction of isoprenoids and fatty acids as case studies.","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"31 1","pages":""},"PeriodicalIF":18.0,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143737140","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}

Here we report a new chromatin state, ‘transcription resistive’, which is differentiated from activation and silencing. Transcription resistive is stamped by H3K36me with almost undetectable transcription activity but open-chromatin state, and occupies most documented plant essential genes. Mutating SDG8, previously known as the major H3K36 methyltransferase in Arabidopsis, surprisingly elevates 78.7% of H3K36me3-marked resistive loci, which accounts for 39.4% of the coding genome. Genetically, SDG8 prevents H3K36me activity of SDG4 at short and intronless genes to secure plant fertility, while it collaborates with other H3K36me methyltransferases on long and intron-rich genes. Together, our results reveal that SDG8 is the primary sensor that suppresses excessive H3K36me, and uncovered that ‘transcription resistive’ is a conserved H3K36me-stamped novel transcription state in plants, highlighting the regulatory diversities and biological significance of H3K36 methylation in eukaryotes.","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"49 1","pages":""},"PeriodicalIF":18.0,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143736959","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}

Moreover, because selection against meiotic abnormalities is expected to be strong in the initial generations, we anticipate HEs to be uncommon in evolved segmental allopolyploids. Here we analysed the whole-genome composition of 202 phenotypically homogeneous and stable rice tetraploid recombinant inbred lines (TRILs) derived from Oryza sativa subsp. japonica subsp. indica hybridization/whole-genome doubling. We measured functional traits related to growth, development and reproductive fitness, and analysed meiotic chromosomal behaviour of the TRILs. We uncover factors that constrain the genomic composition of the TRILs, including asymmetric parental contribution and exclusive uniparental segment retention. Intriguingly, some TRILs that have high fertility and abiotic stress resilience co-occur with largely stabilized meiosis. Our findings comprise evidence supporting the evolutionary possibility of HE-catalysed ‘allo-to-auto’ polyploidy transitions in nature, with implications for creating new polyploid crops.","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"72 1","pages":""},"PeriodicalIF":18.0,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143736961","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}

Here we show that three genes encoding cold-shock proteins (CSPs) were transferred from bacteria to Triticeae, a tribe of the grass family that includes several major staple crops such as wheat, barley and rye. The acquired CSP genes in wheat (TaCSPs) are functionally conserved in their bacterial homologues by encoding a nucleic acid-binding protein. Experimental evidence indicates that TaCSP genes positively regulate drought response and improve photosynthetic efficiency under water-deficient conditions by directly targeting a type 1 metallothionein gene to increase reactive oxygen species scavenging, which in turn contributed to the geographic expansion of wheat. We identified an elite CSP haplotype in Aegilops tauschii, introduction of which to wheat significantly increased drought tolerance, photosynthetic efficiency and grain yields. These findings not only provide major insights into the role of HGT in crop adaptation and domestication, but also demonstrate that novel microbial genes introduced through HGT offer a stable and naturally optimized resource for transgenic crop breeding and improvement.","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"20 1","pages":""},"PeriodicalIF":18.0,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143712971","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}
