With advances in genomics and plant metabolism research, significant progress has been made in understanding the biosynthetic pathways and the underlying regulatory mechanisms of tea plants (<em>Camellia sinensis</em>). Tea metabolites play a pivotal role in determining tea flavor, and functional properties, while also being closely tied to the plant's stress resistance, environmental adaptability, and other newly discovered biological functions. In recent years, research has expanded beyond the well-characterized metabolites, such as catechins, <span>l</span>-theanine, and caffeine, to include volatile compounds, hormones, photosynthetic pigments, lignin, and other recently discovered metabolites, shedding new light on the intricate tea plant metabolism. This review highlights the biosynthetic pathways and regulatory mechanisms of key metabolites in tea plants, with a focus on the critical enzyme genes and regulatory factors. Additionally, emerging technologies and methodologies applied in tea plant metabolism research are briefly introduced. By further exploring the biological functions of tea metabolites and their upstream regulatory networks, future studies may offer theoretical insights and technological support for tea plant cultivation, tea quality improvement, and the sustainable development of the tea industry.</div></div>","PeriodicalId":11003,"journal":{"name":"Current opinion in plant biology","volume":"85 ","pages":"Article 102716"},"PeriodicalIF":8.3,"publicationDate":"2025-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143777268","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The cell plate is produced by the phragmoplast, a plant-specific structure composed of cytoskeletal polymers, membranes, and associated proteins. Initially, the phragmoplast forms as a disk between daughter nuclei at the end of anaphase, then continues to expand outward until the cell plate connects to the parental cell wall. Phragmoplast expansion encompasses dramatic reorganization of microtubules. At the start, microtubules form short antiparallel overlaps that initiate cell plate biogenesis by recruiting membrane material in the form of cytokinetic vesicles. Subsequent membrane expansion and remodeling processes are accompanied by dissolution of the antiparallel overlaps and attachment of microtubules to the cell plate biogenesis machinery. Deposition of oligosaccharides into the lumen confers mechanical rigidity to the cell plate that triggers depolymerization of microtubules. Precise coordination of microtubule organization with vesicle trafficking, membrane remodeling, and the deposition of oligosaccharides plays a critical role for cell plate production. This review summarizes current understanding of key signaling pathways that couple diverse processes in the phragmoplast.</div></div>","PeriodicalId":11003,"journal":{"name":"Current opinion in plant biology","volume":"85 ","pages":"Article 102723"},"PeriodicalIF":8.3,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143769257","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Each plant lineage has created novel metabolites often using the classical duplication/neo-functionalization model, but this is constrained by undersampled genera and an absence of high-quality genomes. Phylogenetically resolved genomes, deeper chemical sampling and mechanistic assessment of glucosinolate diversity in the Brassicales is beginning to fill in a deeper understanding of how chemical novelty arises. This is showing that small-scale duplications like tandem or distal events may have more influence on the formation of metabolic novelty. Similarly, this is showing that gene loss is playing a significant role in metabolic diversity across the entire genera. Finally, mechanistic work is showing that the glucosinolate pathway is not a defined endpoint but is being used as a launching pad for the creation of other metabolites.

VOC signals are perceived and decrypted by receiver plants; however, the emission, composition, distribution and effective range, as well as uptake of these infochemicals depend on temperature and atmospheric chemistry in addition to their physicochemical properties.

Some VOCs are active ingredients with significant economic and medicinal value. For example, monoterpenoids such as linalool, geraniol, menthol, camphor, borneol, citral, and thymol are well-known for their flavor and aroma. Most monoterpenoids have a strong scent and physiological activity; some compounds, like thymoquinone, have excellent anti-cancer activities, making them important for pharmaceuticals and also beneficial in food and cosmetics. VOCs encompass a diverse range of chemical classes, such as terpenoids, benzenoids/phenylpropanoids, amino acid derivatives, and fatty acid-derived compounds. With the development of genomic, transcriptomic, and metabolomic techniques, significant progress has been made in the discovery of genes for the biosynthesis of VOCs. Herein, recent advances in the biosynthesis of plant-derived VOCs, focusing on two main classes: benzenoids/phenylpropanoids and monoterpenes, are discussed. It highlights the identification of a peroxisomal enzyme, benzaldehyde synthase, in petunia that elucidates the biosynthetic pathway of benzaldehyde, and a bifunctional enzyme, geranyl/farnesyl diphosphate synthase (RcG/FPPS1), in roses (<em>Rosa chinensis</em> “Old Blush”) that contributes to the production of cytosolic geranyl diphosphate. Current understanding about canonical and non-canonical pathways for monoterpene formation and some approaches that are useful for gene discovery have been discussed.
