Plant secondary metabolites are critical quality-conferring compositions of plant-derived beverages, medicines, and industrial materials. The accumulations highly variable among seasons; however, the underlying regulatory mechanism remains unclear, especially in epigenetic regulation. Here, we used tea plants to explore an important mark DNA methylation (5mC)-mediated regulation plant metabolism different seasons. Multiple omics analyses were performed on spring summer new shoots. results showed that flavonoids theanine dominated metabolic response seasons In shoots, genes encoding methyltransferases demethylases up-regulated, global CG CHG reduced CHH increased. 5mC promoter gene body regions influenced seasonal expression; amplitude was correlated with transcriptions. These differentially methylated included those enzymes transcription factors which play roles flavonoid pathways. role further verified by applying a inhibitor. findings highlight dynamic plays seasonal-dependent provide insights for improving quality.

Abstract Background Nanotechnology holds revolutionary potential in the field of agriculture, with zinc oxide nanoparticles (ZnO NPs) demonstrating advantages promoting crop growth. Enhanced photosynthetic efficiency is closely linked to improved vigor and superior quality tea plants, complemented by beneficial role phyllosphere microorganisms maintaining plant health. However, effects ZnO NPs on photosynthesis sprouting new shoots, community have not been fully investigated. Results This study investigated physiological parameters plants under influence NPs, content key enzymes such as RubisCO, chlorophyll content, fluorescence parameters, transcriptomic extensive targeted metabolomic profiles leaves mineral element composition these tissues, epiphytic endophytic microbial communities within phyllosphere. The results indicated that could enhance upregulate expression some genes related photosynthesis, increase accumulation products, promote development alter various elements shoots plants. Furthermore, application was observed favorably structure shift dynamics suggests a for contribute health productivity modulating microbiome. Conclusion demonstrates positive impact microorganisms, which can improve growth condition These findings provide scientific evidence sustainable agricultural advancing research nanobiotechnology aimed at enhancing yield quality.

Polygonatum cyrtonema Hua (P. cyrtonema) rhizomes are rich in flavonoids and other secondary metabolites, exhibiting remarkable antioxidant, anti-tumor, immunomodulatory effects. flavonoid-biosynthesis-related genes have been characterized already. However, a comprehensive overview of flavonoid biosynthesis pathways is still absent. To articulate the accumulation pathways, we examined transcriptome changes using Illumina HiSeq from five different tissues RNA-seq 15 samples had over 105 Gb clean base, generating total 277,955 unigenes. The cDNA libraries fruits (F), leaves (L), roots (R), stems (S), (T) three-year-old P. plants generated 57,591, 53,578, 60,321, 51,530, 54,935 Comparative analysis revealed that 379 differentially expressed (DEGs) were group F _vs_ T, L R S transcripts DEGs principally enriched rhizomes. In addition, combined with WGCNA FPKM tissues’ transcription, nine transcription factor families (MYB, WRKY, AP2/ERF, etc.) red module, module positively correlated rhizome accumulation. Quantitative real-time PCR (qRT-PCR) further indicated BZIP1, C3H31, ERF114, DREB21 rhizomes, accompanied development cyrtonema. Therefore, this study provides foundation for research into uncovering

Recent research has highlighted the importance of Cys2/His2-type zinc finger proteins (C2H2-ZFPs) in plant growth and responses to various stressors, complex structures C2H2-ZFP networks molecular mechanisms underlying their stress have received considerable attention. Here, we review structural characteristics classification C2H2-ZFPs, consider recent advances functions. We systematically introduce roles these across diverse aspects biology, encompassing development, biotic abiotic stresses, doing so hope lay foundations for further functional studies C2H2-ZFPs future.
