Summary: Tea microbes play an important role in improving the growth, yield, and quality of tea plants through nutrient cycling, stress management, and pest/disease resistance. These microbes colonize the roots of tea plants and enhance root growth, development, and nutrient uptake, resulting in increased concentration of nutrients and chemical compounds in tea plants. In addition, they also provide protection against harmful pests and diseases.

Summary: Soil microenvironments and plant varieties have unclear effects on the rhizosphere microbial community of tea plants. In this study, the structure and function of rhizosphere microbial communities of two tea varieties were compared. The results showed that the location had a greater impact on the microbial community than the tea varieties, and fungi were more sensitive to changes in microenvironments. Several beneficial microorganisms were also found, which are significant for improving the ecological environment of tea gardens and disease resistance of tea plants.

Summary: Pruning is an important agronomic measure in tea plantation management. This study found that pruning can promote tea tree growth and increase tea yield, but it may reduce the synthesis and accumulation of quality-related compounds in tea leaves. The effects of pruning on rhizosphere soil physicochemical indexes, microbial communities, and metabolic pathways were also analyzed. The results showed that pruning had significant impacts on soil properties and microbial communities, leading to changes in soil nutrient cycle. This study provides important theoretical references for tea plantation management.

Summary: Pruning promotes tea tree growth and yield, but not the synthesis and accumulation of quality-related compounds in tea leaves. It increases organic matter and phosphorus content, while decreases total phosphorus, total potassium, and available nitrogen content in rhizosphere soil. Changes occur in the microbial community and metabolic pathways in tea rhizosphere soil after pruning, with beneficial microorganisms and metabolic pathways increasing and detrimental ones decreasing.

Summary: Tea has gained popularity globally due to its unique flavor and health benefits. 'Yuhua' tea, a type of green tea, is a famous specialty from Nanjing, China. This study examined the impact of soil's physical and chemical properties on the chemical components of 'Yuhua' tea, such as free amino acids, tea polyphenols, and caffeine. The findings suggest that soil management plays a crucial role in improving the quality of 'Yuhua' tea.

Summary: The study investigated the effects of decreasing microbial biomass on mycorrhizal attributes and soil quality indicators, with larger differences observed between areas than between dilution treatments. The results suggest that while AMF inoculation and dilution-to-extinction did not significantly affect soil quality indicators, the bacterial community was found to be impacted and could influence environmental revegetation processes.

Summary: This study elucidated the mechanism of how pea-tea intercropping affects tea quality through transcriptome and metabolome analyses. The results showed that pea intercropping led to a decrease in catechins and an increase in amino acids in tea leaves. Additionally, there were significant differences in gene expression related to amino acid metabolism and flavonoid biosynthesis.

Summary: Soil acidification in tea plantations can significantly reduce tea yield and quality. Using organic fertilizer is an effective method to remediate acidified soil and ensure tea yield and quality. Long-term use of chemical fertilizer can intensify soil acidification and hinder tea tree growth, while the combination of organic fertilizer and chemical fertilizer, as well as the long-term use of organic fertilizer, can improve tea yield and quality.

Summary: The study demonstrates the positive role of arbuscular mycorrhizal fungi in promoting tea plant growth and quality under salt stress by impacting lignin and cellulose synthesis. Differentially expressed genes in tea leaves under salt stress relate mainly to metabolic processes, membrane functions, and catalytic activities. Kyoto Encyclopedia of Genes and Genomes pathways analysis reveals enrichment in cellulose synthesis with AMF and lignin and cellulose synthesis without AMF under salt stress.

Summary: The study investigated the role of Pseudomonas fluorescens ZL22 in soil restoration and phenolic acid autotoxicity (PAA) regulation in tea plantations. ZL22 can degrade 96% of p-hydroxybenzoic acid and 98% of 3,4 dihydroxybenzoic acid in tea rhizosphere soil within 30 days. Its cooccurrence with low cinnamic acid levels further promotes lettuce seed growth and significantly increases tea production. ZL22 effectively regulates PAA in the rhizospheric soil, increases the abundance of genera associated with soil N, C, and S cycling, and creates optimum pH and organic carbon, and available N contents for secondary metabolite accumulation in tea leaves. The application of P. fluorescens ZL22 controls PAA, improves plant growth and soil nutrition, thereby promoting tea production and quality.

Summary: Soil acidification in tea plantations results in excessive heavy metal content in tea, which decreases its yield and quality. The application of shellfish and organic fertilizers to improve soil and ensure safe tea production remains unclear. A two-year field experiment was conducted in tea plantations with acidic soil, excessive lead and cadmium concentrations. The results showed that shellfish and organic fertilizer amendments increased soil pH and nutrient content while decreasing heavy metal content in the soil and tea. The largest amendment of both shellfish and organic fertilizer had the greatest positive effect on all parameters.
