Summary: Research has shown that applying cow manure in tea plantations can significantly improve the metabolic characteristics of tea shoots and enhance the quality of tea leaves. Specifically, organic acids and amino acids play crucial roles in tea plants, and the cow manure treatment also leads to significant increases in amino acids, sugars, and fatty acids in the resulting teas.

Summary: The study found that the tolerance of tea leaves to fluoride is mainly achieved through regulating metabolites and ion balance, with minor polypeptides, carbohydrates, and amino acids playing important roles in this process. Additionally, concentrations of sodium, ferrum, manganese, and molybdenum in tea leaves increased significantly after fluoride treatments, while aluminum decreased. These findings provide new insights into the adaptation of tea plants to fluoride stress.

Summary: Tea seed is rich in bioactive substances and has excellent performance in antioxidant, anti-tumor, anti-obesity, anti-microbial, gastric protection, and other aspects. These properties make it have important application potentials in industry, agriculture, and ecology, as well as new perspectives in drug development and clinical translation. Future research should focus on specific active ingredients, complex structure-activity relationships, bioactive mechanisms, undiscovered health benefits, and manufacturing processes to facilitate the transformation of waste resources into valuable treasures and promote sustainable development and socio-economic growth.

Summary: This study investigated the SOC content in the major tea-producing areas of China and found significant differences in SOC among different regions, climatic zones, and cultivars. Yunnan province had the highest SOC content, the southwest tea-producing area had the highest SOC content among the four regions, and the tropical region had the highest SOC content. Additionally, large-leaf cultivars had higher SOC content compared to middle or small-leaf cultivars. Total nitrogen and available aluminum were identified as the main factors influencing SOC differences. The findings provide valuable information for fertilizer strategies and carbon sequestration policies in tea plantations.

Summary: This study investigated the response of tea plants to nitrogen deficiency. It was found that nitrogen deficiency inhibited the growth of tea plants and led to changes in nitrogen metabolism and gene expression in tea leaves. The study also suggested that nitrogen deficiency might impair phosphorus metabolism in tea leaves. Furthermore, potential genes with the ability to improve the tolerance of nitrogen deficiency in tea plants were identified.

Summary: The study investigated the efficiency of SSR and SCoT markers in analyzing the genetic diversity of tea germplasm from FRC SSC RAS in Russia. The results showed that SSR markers had higher efficiency than SCoT markers, despite the presence of polyploid tea accessions. The study also revealed three distinct genetic clusters within the Russian genebank collection, with the northernmost tea collection exhibiting a greater genetic distance from the other clusters. Additionally, a moderate correlation was found between genome size and leaf area size.

Summary: Ethephon, paclobutrazol, and chlormequat significantly promoted the abscission of flower buds and flowers on the tea plant, reducing the number of tea flowers in the plantations. Additionally, paclobutrazol and chlormequat suppressed the occurrence of anthracnose on the tea plant and induced high catalase and peroxidase activities. Photosynthetic characteristics and biochemical components in the tea plant leaves treated with plant growth regulators decreased significantly.

Summary: This study investigated the absorption and assimilation mechanisms of selenium in tea plants through transcriptomics and proteomics. The results demonstrated that genes related to amino acid and protein metabolism were upregulated under selenite treatment, while genes and proteins associated with glutathione metabolism and biosynthesis were highly expressed. Genes participating in DNA and RNA metabolism were identified in tea plants supplemented with selenate. These findings provide important theoretical references for breeding and cultivating selenium-enriched tea varieties.
