Background: Dihydroflavonol 4-reductase (DFR) is a key enzyme in the flavonoid biosynthetic pathway that regulates anthocyanin and proanthocyanidin accumulation plants. Although DFR genes have been studied various species, their origin of gene family, its distribution across plant kingdom, reasons behind emergence different subtypes Methods: This study performed whole-genome analysis 237 including algae, mosses, ferns, gymnosperms, angiosperms, integrating phylogeny, conserved motifs, duplication mechanisms, positive selection, expression pattern analyses. Results: These results indicate family originated from common ancestor extant ferns seed plants, asparagine (Asn)-type aspartic (Asp)-type DFRs associated with gymnosperms. Notably, we report for first time presence Asn-type, Asp-type, arginine (Arg)-type some which breaks previous notion Arg-type are exclusive to ferns. Tandem considered primary driving force expansion formation subtypes. Furthermore, Asn-type were highly expressed during early stages development, suggesting important role development. Conclusions: Overall, this revealed dynamic evolutionary trajectory providing theoretical foundation future research on genes.

Abstract Elaeagnus mollis Diels, is a rare and endangered woody plant endemic to China, which listed on the IUCN Red List. In natural state, viability of its seeds declines very rapidly, key status, but mechanism E. seed decline still unclear. order explore physiological molecular seeds, this study used fresh as control compare analyze changes vitality, antioxidant system, transcription metabolomics, when were stored for 1 3 months at room temperature. The decreased continuously after month storage. activities superoxide dismutase (SOD), monodehydroascorbate reductase (MDHAR), ascorbate (AsA), glutathione (GSH) significantly, while catalase (CAT) activity increased gradually during viability. Transcriptomic results showed that total 801 differentially expressed genes (DEGs) identified between 1-month-stored 1,524 3-month-stored seeds. Among them, expression CAT , MDHAR GSH GR consistent with indicators. Moreover, WRKY C3H bZIP B3 bHLH NAC AP2 / ERF-ERF factors are important in regulating Metabolomics types differential accumulated metabolites (DAMs) mainly flavonoids, amino acids derivatives, phenolic acids. combined analysis transcriptomics metabolomics further DEGs DAMs associated co-enriched flavonoid biosynthesis tryptophan metabolism pathways. Also 22 genes, including ALDH CHS C4H participating This also illustrated metabolic pathways involved by acting system. These findings provide new insights into .

Anthocyanins are significant secondary metabolites that essential for plant growth and development, possessing properties such as antioxidant, anti-inflammatory, anti-cancer activities cardiovascular protection. They offer potential applications in food, medicine, cosmetics. However, since anthocyanins mainly obtained through extraction chemical synthesis, they encounter various challenges, including resource depletion, ecological harm, environmental pollution, the risk of toxic residuals. To address these issues, this study proposes a cell factory approach novel alternative solution anthocyanin acquisition. In study, VdCHS2 gene was successfully transformed into spine grape cells, obtaining high-yield line designated OE1. Investigations light spectrum demonstrated white promoted growth, while short-wavelength blue significantly boosted production. Targeted metabolomics analysis revealed total content OE1 reached 11 mg/g, representing 60% increase compared to WT. A 54 differentially accumulated were identified, among which 44 upregulated. Overexpression CHS enhanced expression downstream genes involved biosynthesis, resulting differential CHI, F3Hb, F3′5′H, DFR4, LDOX. This led accumulation monomers, predominantly consisting 3-O-glucosides 3-O-galactosides, thereby causing alterations levels composition. Furthermore, increased activity antioxidant enzymes, improved clearance reactive oxygen species, reduced hydrogen peroxide (H2O2) malondialdehyde (MDA). The subsequent cultivation line, conjunction with suspension culture, established production, increasing yield shortening culture duration. elucidates molecular mechanisms influenced compositional variations. Additionally, it model small-scale factory, providing theoretical practical foundation targeted synthesis components development utilization natural products.
