Summary: Appropriate postharvest conditions are crucial for protecting freshly harvested plant products and minimizing economic losses. This study investigated the impact of low-temperature transportation on postharvest tea leaves using metabolomics and transcriptomics approaches. The refrigerated tea leaves showed significant differences in metabolite expression, particularly in flavonoids, amino acids, and purine alkaloids. The differential regulation of these metabolites was attributed to specific genes and transcription factors that were influenced by the refrigerated environment. Understanding the mechanisms underlying these metabolic changes can help optimize postharvest transportation parameters and maintain tea quality.

Summary: In this study, the development and genetic regulation of stomata in tea plants were investigated. It was found that stomata development and stomata lineage genes were regulated by light intensity and temperature stress, and were closely related to dehydration tolerance. Moreover, triploid tea varieties exhibited lower stomatal density and larger size, as well as lower expression levels of key stomata lineage genes such as CsSPCHs, CsSCRM, and CsFAMA. This study provides new insights into the morphological development and genetic regulation of stomata in tea plants, and lays a foundation for future improvement of water use efficiency.

Summary: In this study, a comprehensive identification and analysis of GSTs in tea plant were conducted, and their important roles in plant growth, development, and stress responses were revealed. The study found that CsGSTs were unevenly distributed across the tea plant genome and tandem duplication was the main driving force for their expansion. Furthermore, CsGSTs were found to respond to multiple stresses and exhibit different expression patterns in different tissues. CsGSTU19, localized in the nucleus and cell membrane, was proven to be involved in tea plant defense against temperature stresses and Co. camelliae infection.

Summary: A SYBR Green real-time quantitative polymerase chain reaction (RT-qPCR) method was developed to detect four virus segments of Tea plant necrotic ring blotch virus (TPNRBV). The study found that mature leaves contained the highest viral load, while the concentrations of the virus in other tissues decreased with increasing distances from symptomatic leaves. TPNRBV did not efficiently spread through seeds, cuttings, or mechanical inoculation, but was transmitted to some tea cultivars under field conditions.

Summary: Cold stress is a significant environmental factor that negatively affects tea plant growth and productivity. The application of exogenous ascorbic acid improves the cold tolerance of tea plants by reducing lipid peroxidation and enhancing photosynthetic efficiency. Transcriptome analysis reveals that ascorbic acid treatment modulates the expression of cell wall remodeling-related genes. These findings suggest that ascorbic acid maintains ROS homeostasis by down-regulating the ROS-scavenging system and exerts protective effects through cell wall remodeling. Ascorbic acid can be used as a potential approach to enhance the cold tolerance of tea plants without pesticide residual concerns.

Summary: In this research, the differences between purple-red and white-yellow tea plant cultivars were compared on biochemical and proteome levels. The study found that purple-red cultivars had higher polyphenols/amino acid ratio while white-yellow cultivars had higher amino acid content. It was also discovered that tea plants with purple-red leaves performed better in photosynthesis compared to yellow-white tea plant cultivars, while the chloroplast development of white-yellow tea plant cultivars was obstructed.
