However, relatively little is known about their biosynthesis. To address this, we investigated the biosynthesis of salviarin, the most abundant furanoclerodane structure in the ornamental sage Salvia splendens. Using a self-organizing map and mutual rank analysis of RNA-seq co-expression data, we identified three cytochrome P450 enzymes responsible for the consecutive conversion of kolavenol into the salviarin precursors: annonene, hardwickiic acid, and hautriwaic acid. Annonene and hardwickiic acid have been proposed as intermediates in the biosynthesis of salvinorin A, and we therefore tested for a common evolutionary origin of the furanoclerodane pathway in these Salvia species by searching for homologous genes in available data for S. divinorum. The enzymes encoded by orthologous genes from S. divinorum displayed kolavenol synthase, annonene synthase, and hardwickiic acid synthase activity, respectively, supporting the view that these are intermediate steps in the biosynthesis of salvinorin A. We further investigated the origin of annonene synthase and the role of gene duplication in the evolution of this specific activity. Our work shows how S. splendens can serve as a model species for the study of furanoclerodane biosynthesis in Salvia species, contributes to understanding the evolution of specialized metabolism in plants, and provides new tools for the production of salvinorin A in biotechnological chassis.</p>","PeriodicalId":52373,"journal":{"name":"Plant Communications","volume":" ","pages":"101286"},"PeriodicalIF":9.4,"publicationDate":"2025-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12143158/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143460594","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

HIFs consist of various aromatic compounds, including quinones, lignin monomers, and flavonoids. However, the downstream molecular pathways that orchestrate these developmental events are largely unknown. Here, we report that S. hermonthica root-tip cells rapidly deposit lignin, a major cell wall component, in response to HIFs. In addition to enhancing lignin levels, HIFs strongly induce genes involved in lignin monomer biosynthesis and polymerization, including several respiratory burst oxidase homologs (RBOHs) and class III peroxidases.

Sugarcane mosaic virus (SCMV) is a representative member of the monocot-infecting potyviruses with a polyadenylated RNA genome, which can be captured by single-cell RNA sequencing (scRNA-seq). Here, we performed scRNA-seq on SCMV-infected maize leaves during early systemic infection (prior to symptom manifestation) to investigate the co-variation patterns between viral accumulation and intracellular gene expression alterations. We identified five cell types and found that mesophyll-4 (MS4) cells exhibited the highest levels of viral accumulation in most cells. Early systemic infection of SCMV resulted in a greater upregulation of differentially expressed genes, which were mainly enriched in biological processes related to translation, peptide biosynthesis, and metabolism. Co-variation analysis of the altered maize gene expression and viral accumulation levels in MS1, 2, and 4 revealed several patterns, and the co-expression relationships between them were mainly positive. Furthermore, functional studies identified several potential anti- or pro-viral factors that may play crucial roles during the early stage of SCMV systemic infection.

Here, we introduce PlantRing, an innovative, nano-flexible sensing system designed to address these challenges. PlantRing employs bio-sourced carbonized silk georgette as the strain-sensing material, offering an exceptional detection limit (0.03%-0.17% strain, depending on sensor model), high stretchability (tensile strain up to 100%), and remarkable durability (season-long use). PlantRing effectively monitors plant growth and water status by measuring organ circumference dynamics, performing reliably under harsh conditions, and adapting to a wide range of plant species. Applying PlantRing to study fruit cracking in tomato and watermelon has revealed a novel hydraulic mechanism characterized by genotype-specific excess sap flow within the plant to fruiting branches. Its high-throughput application has enabled large-scale quantification of stomatal sensitivity to soil drought-a long-standing aspiration in plant biology-facilitating the selection of drought-tolerant germplasm. Combining PlantRing with a soybean mutant has led to the discovery of a potential novel function of the circadian clock gene GmLNK2 in stomatal regulation.

Nucleotide sequencing is key to pathway elucidation efforts, and analyses of the molecular structures of natural products, although seldom discussed explicitly, also play an important role by suggesting hypothetical pathways for testing. Structural analyses are also important in drug discovery, for which many molecular representation systems-methods of representing molecular structures in a computer-friendly format-have been developed. Unfortunately, pathway elucidation investigations seldom use these representation systems. This gap likely occurs because those systems are primarily built to document molecular connectivity and topology rather than the absolute positions of bonds and atoms in a common reference frame, which would enable chemical structures to be connected with potential underlying biosynthetic steps. Here, we expand on recently developed skeleton-based molecular representation systems by implementing a common-reference-frame-oriented system. We tested this system using triterpenoid structures as a case study and explored its applications in biosynthesis and structural diversity tasks. The common-reference-frame system can identify structural regions of high or low variability on the scale of atoms and bonds and enable hierarchical clustering that is closely connected to underlying biosynthesis. Combined with information on phylogenetic distribution, the system illuminates distinct sources of structural variability, such as different enzyme families operating in the same pathway.

Eggplant (Solanum melongena) is unique, as its fruit accumulates anthocyanins beginning from fruit set, and these are later replaced by the yellow flavonoid-pathway intermediate naringenin chalcone. To decipher the genetic regulation of this extraordinary pigmentation shift, we integrated mRNA and microRNA (miRNA) profiling data obtained from developing eggplant fruit. We discovered that SQUAMOSA PROMOTER BINDING-LIKE (i.e., SPL6a, SPL10, and SPL15), MYB1, and MYB2 transcription factors (TFs) regulate anthocyanin biosynthesis in early fruit development, whereas the MYB12 TF controls later accumulation of naringenin chalcone. We further show that miRNA157 and miRNA858 negatively regulate the expression of SPLs and MYB12, respectively.
