“…In addition to dietary foods, humans consume many other plant-derived products such as wine, coffee, and tea. Today, metabolomics has been used to evaluate the quality of those typical plant-derived products, to correlate metabolites with taste and health properties in humans, and to promote the production of high-quality health-benefit plantderived drinks [96][97][98][99][100]. Increasing studies begin to focus on metabolomics responses of humans to these plant-derived beverages as well.…”

“…Metabolite variation in tea is controlled mainly by genetic mechanisms and regulated by environments and agricultural practices, thus profoundly affecting tea quality and flavor. Therefore, there is clear metabolite variation among various tea with different categories and grades [102,103], at different developmental stages [104], and during different manufacturing processes [99]. As a result, metabolic markers identified by metabolomics are important elements for effective evaluation of tea quality under any abovementioned condition.…”

Plant metabolomics plays important roles in both basic and applied studies regarding all aspects of plant development and stress responses. With the improvement of living standards, people need high quality and safe food supplies. Thus, understanding the pathways involved in the biosynthesis of nutritionally and healthily associated metabolites in plants and the responses to plant-derived biohazards in humans is of equal importance to meet people’s needs. For each, metabolomics has a vital role to play, which is discussed in detail in this review. In addition, the core elements of plant metabolomics are highlighted, researches on metabolomics-based crop improvement for nutrition and safety are summarized, metabolomics studies on plant natural products including traditional Chinese medicine (TCM) for health promotion are briefly presented. Challenges are discussed and future perspectives of metabolomics as one of the most important tools to promote human nutrition and health are proposed.

“…The tea plant is an economically important woody species, as its young leaves are the raw material for tea processing ( Zeng et al, 2020 ). However, the tea geometrid ( Ectropis obliqua ), one of the most common herbivores in tea plantations, always causes serious damage to tea production, reducing the quality of tea ( Jiang et al, 2019 ; Zhang J. et al, 2020 ). Chemical insecticides are commonly used for controlling tea geometrid, but they are harmful to both the environment and human health ( Xin et al, 2016 ).…”

Exogenous Application of Gallic Acid Induces the Direct Defense of Tea Plant Against Ectropis obliqua Caterpillars

Gallic acid (GA), an important polyphenolic compound in the plant, is a well-known antioxidant, antihyperglycemic, and anti-lipid peroxidative agent. Recently, GA treatment exhibited ameliorative effects on plants in response to some abiotic stresses. However, the elicitation effect of GA on plant defense against herbivorous insects has not yet been reported. In this study, we found that the exogenous application of GA induced the direct defense of tea plant (Camellia sinensis) against tea geometrid (Ectropis obliqua) larvae, through activating jasmonic acid (JA) signaling and phenylpropanoid pathways. These signaling cascades resulted in the efficient induction of several defensive compounds. Among them, astragalin, naringenin, and epigallocatechin-3-gallate were the three of the most active anti-feeding compounds. However, the exogenous GA treatment did not affect the preference of E. obliqua female moths and larval parasitoid Apanteles sp. Our study suggests that GA may serve as an elicitor that triggers a direct defense response against tea geometrid larvae in tea plants. This study will help to deepen the understanding of the interaction between plants and phytophagous insects and also provide theoretical and technical guidance for the development of plant defense elicitors.

“…The most abundant catechin in green tea is epigallocatechin gallate (EGCg), which makes up approximately 50 to 75% of the total catechins. In recent years, "omics" have grown in popularity to decipher the complex biological processes in organisms, with the rapid development of bioinformatics (Jiang et al, 2019). Metabolomics studies the micro-molecular intermediates and metabolic products derived from specific cellular biological processes/pathways.…”

Camellia sinensis (L.) O. Kuntze (tea) is one of the most widely consumed beverages across the world, serving as an essential commodity crop for several developing countries. A bulk of tea’s health-promoting properties are attributed to the antioxidant properties of EGCg, its predominant polyphenol. As a result of these health benefits, tea production and consumption has expanded and promoted the development of tea industries globally. Tea cultivation is dependent on a good distribution of rainfall, and the current changes in climate pose a significant threat to its global supply chains. Through the efforts of the International Centre for Tropical Agriculture (CIAT), predictions of future climate changes in the tea growing regions of Kenya between now and 2050 have been generated. A study was conducted to develop models to identify key tea growing regions that will remain ideal for tea farming and also investigate the metabolomic differences between 243 drought susceptible NonCommercial (NComm) and 60 Commercial (Comm) cultivars. Non-targeted, high-resolution UPLC-MS was used to attain a new profound understanding of the metabolomic multiplicity between the Comm and NComm groups and to elucidate their association with tea liquor quality and drought tolerance. Several metabolites, namely argininosuccinate, caffeic acid, caffeine, catechin, citric acid, epicatechin, epigallocatechin gallate, gallic acid, gluconic acid, glucose, maltose, quercetin and theanine were found to clearly differentiate between the Comm and NComm cultivars. These detected metabolites were linked to improved tea quality and drought tolerance in the Comm cultivars.
