Two mathematical models of polyphenols extraction from green tea leaves were tested: Peleg’s model and First-order model. Thermodynamical parameters the process determined. For we got following analytical equation: Ct= t/(0.2570207+0.0324377*t). Ct is a concentration in extract at time t. equation describing was as follows: Ct=23.09278*(1-exp(-0.1418264*t)). Goodness fit both high but first-order prognosed equilibrium infusion with much more precisely than Activation energy for equal to 2798 j/mol. Entropy change (ΔS) this 52 (J, (mol, K−1)), enthalpy (ΔH) 16304 (Jmol−1). The ΔG value gradually decreased temperature increased, indicating that increasing can make easier. First Order Model shown be well process. most useful conditions 70 ℃ 20 min.

ABSTRACT High temperatures significantly affect tea yield and quality. Arginine methylation is crucial for plant growth environmental adaptation. However, its role in regulating responses to high remains unclear. In this study, we identified an important Type II arginine methyltransferase, PRMT5, plants confirmed methyltransferase activity both vivo vitro. Our findings revealed that CsPRMT5‐mediated symmetric dimethylation of histone H4R3 (H4R3sme2) was markedly reduced under high‐temperature conditions plants. Both the inhibitor gene‐silencing approaches led decreased levels H4R3sme2 modification, resulting alterations theanine catechins. We employed a genome‐wide approach analyze RNA sequencing (RNA‐seq) subjected ambient temperatures, PRMT5 inhibitors, silencing, along with CsPRMT5 chromatin immunoprecipitation (ChIP‐seq). Comparative analysis these datasets indicated genes regulated by were predominantly enriched within reactive oxygen species (ROS), calcium ion, hormone signalling pathways elevated temperature conditions. Furthermore, validated CsCDPK9 as target gene found silencing resulted increased content catechin at temperatures. suggest plays pivotal plants, well their adaptability fluctuations This study provides new insights into breeding strategies aimed developing crops are better equipped withstand changes induced climate change.

The tea plant (Camellia sinensis) is an important economic crop, which becoming increasingly popular worldwide, and now planted in more than 50 countries. Tea green leafhopper one of the major pests plantations, can significantly reduce yield quality during growth plant. In this study, we report a genome assembly for DuyunMaojian plants using combination Oxford Nanopore Technology PromethION™ with high-throughput chromosome conformation capture technology used multi-omics to study how responds infestation leafhoppers. final was 3.08 Gb. A total 2.97 Gb mapped 15 pseudo-chromosomes, 2.79 them could confirm order direction. contig N50, scaffold N50 GC content were 723.7 kb, 207.72 Mb 38.54%, respectively.

Osteoporosis (OP), osteoarthritis (OA), and rheumatoid arthritis (RA) are common bone joint diseases with a high incidence long duration. Thus, these conditions can affect the lives of middle-aged elderly people. Tea drinking is traditional lifestyle in China, long-term intake tea its active ingredients beneficial to human health. However, mechanisms action against OP, OA, RA not completely elucidated. This study aimed assess therapeutic role related RA. Moreover, it expanded potential efficacy based on network pharmacology molecular docking. Results showed that has anti-COX properties hormone-like effects. Compared single component, different components synergize or antagonize each other, thereby resulting more evident dual effect. In conclusion, great medical healthcare fields. Nevertheless, further research composition, proportion, synergistic mechanism several should be performed.
