Summary: Tea plants, known for their long cultivation history, have a complex genetic background due to self-incompatibility and extensive hybridization. Molecular markers have been instrumental in understanding the tea germplasm resources, including the origin, preservation, and identification, as well as breeding of excellent cultivars of tea plants. However, existing information on molecular markers in tea plants is scattered, making it challenging to grasp the advancements. This paper provides a comprehensive summary of the development and types of molecular markers, their application in tea plants, and offers perspectives for future research.

Summary: The recent availability of tea plant genomes has led to interest in using reverse genetics to study gene function in tea. However, the absence of an efficient transformation system has been a challenge. Virus-induced gene silencing (VIGS) could be a suitable choice for validating gene function in tea. This study used phytoene desaturase (PDS) as a reporter gene to evaluate the VIGS system and found that petiole injection was the most effective method.

Summary: Nitrogen is a crucial nutrient for tea plants, contributing to tea yield and quality. However, excessive use of nitrogen fertilizers in tea plantations leads to environmental pollution and increased costs. Understanding nitrogen metabolism in tea plants is essential for improving nitrogen use efficiency (NUE). This review summarizes the regulation and functioning of enzymes and transporters involved in nitrogen acquisition and metabolism in tea plants, and discusses the challenges and prospects for further research on NUE improvement.

Summary: Genome variation plays an important role in plant phenotypic modeling, adaptive evolution, and gene expression regulation. However, the large genome size of tea plants makes the identification of genome-wide variants time-consuming and expensive. To address this issue, researchers have developed TeaPVs, the first web service database for tea tree genetic variation. It integrates different types of sequencing data and provides comprehensive search functions for SNP, Indel, SV mutations, and SSR/Polymorphic SSR sequences. The TeaPVs database serves as a valuable bioinformatics platform for researchers interested in studying tea plant genetics, identifying functional mutations, and facilitating molecular marker-assisted breeding.

Summary: The study found that the bacterial diversity in tea plant rhizosphere soil is closely related to water content, pH, organic carbon, and total nitrogen. Nitrogen has the greatest impact on bacterial diversity, while carbon, potassium, water, and pH are positively correlated with the abundance of Pedobacter and Mucilaginibacter genera.

Summary: This study identified potential markers for tea authenticity assessment using non-targeted metabolomics in unique oolong tea cultivars. A classification model based on these markers was developed and successfully discriminated the oolong tea samples. The combination of non-targeted metabolomics and chemometric methods can provide high resolution markers for tea authenticity assessment.

Summary: Tea consumption has been found to decrease the risk of cardiovascular disease (CVD) mortality, but the specific components responsible for this effect are not well understood. A study identified a cystatin called CsCPI1 in tea, which promotes antithrombotic activity. CsCPI1 has shown therapeutic effects in mouse models of thrombotic disease and ischemic stroke, increasing nitric oxide production and inhibiting platelet aggregation. This suggests that CsCPI1 may be a potent antithrombotic agent that contributes to the cardiovascular benefits of tea consumption.

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: This study found that Colletotrichum camelliae, a dominant fungal pathogen in tea fields in China, infects tea plants and promotes disease development by regulating tea plant lipid metabolism pathway. The research on CcCp1 protein revealed its key role in fungal pathogenicity. Furthermore, differential gene expression and metabolite accumulation were observed in tea-resistant and tea-susceptible cultivars, suggesting the involvement of various metabolites in plant response to fungal infection.

Summary: This study identified and characterized the causative agents of tea gray blight disease in Taiwan, revealing seven well-classified taxa and seven tentative clades within three genera, including one novel species and five newly recorded species. Pathogenicity assessments showed that all assayed isolates were pathogenic on tea leaves, with Pseudopestalotiopsis chinensis and Pseudopestalotiopsis camelliae-sinensis identified as the major pathogens associated with gray blight disease of tea in Taiwan. This study is the first to focus on the diversity, pathogenicity, and characterization of pestalotiopsis-like fungi causing tea gray blight disease in Taiwan.
