Abstract ：
Background Epigallocatechin gallate (EGCG) imparts unique health benefits and flavour to tea. Photosynthesis plays a crucial role in modulating secondary metabolite production in plants, and this study investigated its impact on the biosynthesis of EGCG in tea plants under different ecological conditions. Results Enhanced photosynthetic activity and the increased EGCG content, total esterified catechins (TEC), total catechins (TC) responded synchronously to changes in ecological factors. The photosynthetic capacity of tea plants and the EGCG content fit surface model equations (Extreme 2D and Polynomial 2D) and multiple regression equations (R-2 > 70%). Additionally, logistic regression and ROC curves revealed that photosynthetic capacity was related to EGCG accumulation patterns in response to ecological variations. Upon perceiving ecological changes, the response of photosynthesis-related genes (CspsaA from photosystem I, CspsbB, CspsbC from photosystem II, and CsLHCB3 from the antenna protein pathway) was associated to carbon cycle-related genes (CsALDO, CsACOX, CsICDH, Csrbcs), which mediated the expression of CsPAL in the phenylalanine pathway; CsaroDE in the shikimate pathway; and CsCHS, CsF3H, CsF3'H, and CsANS in the flavonoid pathway. Eventually, this influenced the accumulation of EGCG and its precursors (gallic acid and epigallocatechin) in tea plants. Conclusions This study reveals the effects of photosynthesis on EGCG biosynthesis in response to ecological factors, providing insights for optimizing tea cultivation and quality.

Abstract ：
To elucidate the characteristic aroma of Hainan Dayezhong black tea, GC-MS, GC-olfactometry, and electronic nose analyses were used to examine the changes in volatile compounds. A total of 527 volatiles were identified and quantified, of which 80 compounds with relative odor activity values exceeding 1 in dried tea samples were selected as biomarkers. Floral and sweet-associated volatiles, including damascenone, benzaldehyde, and linalool, were proposed to be responsible for the characteristic aroma. Our results indicated that multiple stresses occurring during withering, rolling, and fermentation contributed to the distinctive floral aroma, while the thermal effects of drying enhanced sweet odors by volatilizing certain fragrant compounds, thereby improving the final quality of the dried tea. These findings provide a foundation for quality control in practical manufacturing and will contribute to the development of standard operating procedures for producing Hainan Dayezhong black tea with desirable aromas.

Abstract ：
Catechins, the most important bioactive components in tea plants (Camellia sinensis), are influenced by the growth environment. To identify and optimize the key meteorological factors affecting catechin accumulation, we investigated the relationship between meteorological factors and tea plant catechin biosynthesis across three growing seasons at 10 locations. Rainfall, average temperature, and effective accumulated temperature (EAT) were identified as key drivers regulating catechin accumulation via the responsive expression of key structural genes CsCHS1, CsANR, and CsSCPL. Optimal meteorological conditions for enhancing total esterified catechins (TEC) and total non-esterified catechins (TNEC) were determined using LINGO software, although the optimal conditions for these two groups were contrasting. Hot and rainy environments promote the biosynthesis of EGCG, ECG, and TEC through CsPAL and CsSCPL, while reduced rainfall and EAT promote the accumulation of C, EGC, and TNEC. This study reveals the differential effects of meteorological factors on catechin accumulation and obtains optimal meteorological conditions for promoting catechin accumulation. These results provide guidance for improving catechin accumulation and tea cultivation management.

Abstract ：
Ecological factors directly influence the growth and metabolism of tea plants (Camellia sinensis L.), and unfavorable environmental conditions cause abiotic stress to them. Abiotic stress causes damage to reliable, high-quality, and safe tea production, yet the optimal ecological conditions for enhancing both yield and quality remain unclear. To investigate the response patterns of shoot growth to ecological factors and its relationship with catechin accumulation, this study conducted the cultivation of tea plants with a precise modulation of both individual and combined ecological parameters. Under 30 degrees C and 90% air humidity, specific combinations of light intensity and substrate relative humidity ("250 mu molm-2s-1 + 65%" or "350 mu molm-2s-1 + 70%") significantly enhanced growth and yield. A significant correlation between shoot growth and catechin accumulation was observed, and mathematical models further revealed a synergistic response between shoot growth capacity and total catechin content to ecological factors. Furthermore, co-expression analysis indicated that catechin biosynthesis-related genes exhibited coordinated expression with key growth-related genes, including CsTCP, CsErf, and CsXth. In conclusion, these findings identify optimal ecological conditions to mitigate abiotic stress and reveal a synergistic relationship between catechin biosynthesis and shoot growth, providing an ecological basis for balancing yield and quality in tea production.

Abstract ：
Gallic acid (GA), as a precursor of Epigallocatechin-3-gallate (EGCG) biosynthesis in tea plant, is one of the important components of tea flavor and has various health benefits. However, the mechanism of endogenous hormones regulating GA biosynthesis during the development of buds and leaves of tea shoots is still unclear. In this study, the buds and leaves of five different developmental stages of tea shoots were used as test materials to explore the mechanism of endogenous hormone signaling pathway regulating GA biosynthesis. The results showed that the decrease of D-erythrosyl-4-phosphate content and the increase of shikimic acid content affected the accumulation of GA content during the development of tea shoots. Jasmonic acid, abscisic acid, auxin, cytokinin, and gibberellin inhibited GA biosynthesis by down-regulating the expression of two CsaroDEs through twenty-three plant hormone signal transduction factors, such as CsMYC2, CsSNRK2, CsARR-A, and CsDELLA, respectively, which mediated the downregulation of sixteen transcription factors, such as CsMYB44, CsMYB108, and CsC2C2. CsMYC2 and CsSNRK2 co-mediated the downregulation of the expression of CsMYB44 and CsMYB108 in response to changes in endogenous JA and ABA content, respectively, and inhibited the expression of CsaroDE, thereby co-regulating GA biosynthesis. CsMYC2 may be a key interworking site for the endogenous Jasmonic acid and abscisic acid signaling pathways to jointly regulate GA biosynthesis. Our findings revealed the potential mechanism of endogenous hormones regulating GA biosynthesis during the development of buds and leaves of tea shoots and provided a scientific basis for the regulation of tea quality.

Abstract ：
To clarify the contributions of stems and leaves to the aroma of oolong tea, GC-MS and RNA-sequencing analyses were conducted on samples over Tieguanyin tea production. Totally, 1147 metabolites involving volatile terpenoids, fatty acids, phenylpropanoids/benzenoids, and carotenoid derivatives accounting for oolong tea aroma development, of which 21, 12 and 21 VOCs were selected as the biomarkers, and 14, 11 and 9 significant pathways enriched in the stem, 1st leaf and 2nd leaf samples respectively. Floral and fruity volatiles, including Damascone, beta-Ionone, Geraniol, and Linalool, were significantly enriched in stems, while Nerolidol and alpha-Farnesene predominantly accumulated in leaves. Analysis of odor activity values revealed that floral-fruity volatiles were present in both stem and leaf parts, with green-leaf odors mainly preserved in the stems. However, the thermal effects in fixing and drying operations significantly reduced the abundance of green-leaf odor, while preserving most floral-fruity odor in both stem and leaf sections.

Abstract ：
In the context of smart agriculture, the tea industry is undergoing a transformative shift toward intelligent development. As the birthplace of tea, China holds a significant position in the global tea industry, with Anxi County in Quanzhou City, Fujian Province-renowned as the origin of Tie Guan Yin-standing as the world's largest oolong tea production area. Its intelligent transformation of the tea industry is typical and representative. However, current research on the digital literacy of farmers is not yet mature, and there is a lack of systematic research on this specific group of tea farmers, which to some extent restricts the transformation of the tea industry towards intelligent development. The level of digital literacy among tea farmers is crucial for the intelligent development and transformation of the tea industry. Improving the digital literacy of tea farmers is the key to promoting the intelligent development of the tea industry. Therefore, studying the digital literacy of tea farmers has significant practical significance. This article takes Anxi County as the research area and focuses on moderate-scale tea farmers as the research object. Based on the United Nations Global Framework for Digital Literacy and taking into account the actual situation of tea farmers, an evaluation index system and analysis framework for tea farmers' digital literacy have been constructed from seven dimensions: equipment and software operation skills, digital information literacy, digital communication and collaboration literacy, digital content creation literacy, digital security literacy, problem-solving literacy, and professional digital literacy. Using literature review, questionnaire survey, interview, and quantitative analysis methods, a questionnaire containing the above-mentioned dimensions was designed. After collecting data, the rationality of the questionnaire structure was verified using SPSS software. The digital literacy level of 440 medium-sized tea farmers from 11 major tea-producing townships in Anxi County was measured, analyzed, and Two-Tailed correlation tests were conducted. The results indicate that there are currently six aspects of digital literacy among tea farmers that are at a moderate level, and professional digital literacy is the weakest among the seven digital literacy. The overall digital literacy level of tea farmers needs to be strengthened. Large-scale tea farmers have the conditions to apply smart agricultural equipment and technology, which can achieve intelligent and refined management of tea gardens and intelligent upgrading of the entire industry chain. Based on the research results of the seven digital literacy of tea farmers, this article proposes improvement measures corresponding to the seven digital literacy of tea farmers from the perspectives of "government, industry associations, and training institutions", providing reference for Anxi County and other tea-producing areas in the world.

Abstract ：
Aging, characterized by a gradual decline in physiological function, is a major risk factor for chronic diseases. White tea, one of China's traditional tea types, exhibits various health benefits due to its unique chemical composition, with its anti-aging potential drawing increasing attention. Gallic acid (GA), one of the important bioactive components in white tea, possesses antioxidant and anti-inflammatory properties, but its anti-aging mechanisms remain unclear. In this study, high-performance liquid chromatography was used to analyze the evolution of GA content and to determine the antioxidant capacity of aged white tea. Results revealed that the GA content increased with storage time, accompanied by a corresponding enhancement in the antioxidant potency composite index (APC). Network pharmacology predicted 40 potential anti-aging targets of GA, and protein-protein interaction network analysis identified six key targets (MAOA, PTGS2, BCL2, APP, IGF1R, SERPINE1). Functional enrichment analysis indicated that the anti-aging effects of GA are mediated through multiple pathways, particularly those related to oxidative stress. Molecular docking results demonstrated that GA could bind effectively to the six key targets via hydrogen bonding and hydrophobic interactions. Furthermore, molecular dynamics simulations confirmed the binding stability of GA with MAOA, PTGS2, and BCL2. This study systematically elucidates the evolution of GA in aged white tea and its potential anti-aging mechanisms, providing a theoretical basis for the development of GA and aged white tea as functional anti-aging additives.

Abstract ：
Catechins, a class of polyphenolic compounds found in tea, have attracted significant attention due to their numerous health benefits, particularly for the treatment and protection of hypertension. However, the potential targets and mechanisms of action of catechins in combating hypertension remain unclear. This study systematically investigates the anti-hypertensive mechanisms of tea catechins using network pharmacology, molecular docking, and molecular dynamics simulation techniques. The results indicate that 23 potential anti-hypertensive targets for eight catechin components were predicted through public databases. The analysis of protein-protein interaction (PPI) identified three key targets (MMP9, BCL2, and HIF1A). KEGG pathway and GO enrichment analyses revealed that these key targets play significant roles in regulating vascular smooth muscle contraction, promoting angiogenesis, and mediating vascular endothelial growth factor receptor signaling. The molecular docking results demonstrate that the key targets (MMP9, BCL2, and HIF1A) effectively bind with catechin components (CG, GCG, ECG, and EGCG) through hydrogen bonds and hydrophobic interactions. Molecular dynamics simulations further confirmed the stability of the binding between catechins and the targets. This study systematically elucidates the potential mechanisms by which tea catechins treat anti-hypertension and provides a theoretical basis for the development and application of tea catechins as functional additives for the prevention of hypertension.
