Summary: Squalene, a precursor of steroids with diverse bioactivities, was found in tea leaves and its content varied among different cultivars. The squalene content in tea leaves increased with leaf maturity, and the old leaves from the previous year had the highest level of squalene. The squalene levels also differed significantly among the 30 cultivars tested, with cultivar Pingyun having the highest level. The old tea leaves and pruned littering can serve as alternative sources for natural squalene extraction.

Summary: Different methods for extracting and analyzing odor-active compounds in Dahongpao Wuyi Rock Tea were compared. The results showed that two-dimensional gas chromatography-olfactometry-mass spectrometry (GCxGC-O-MS) is superior to GC-O-MS, and stir bar sorptive extraction (SBSE) can extract more odor-active compounds. Aroma extraction dilution analysis (AEDA) and odor activity value (OAV) identified 15 compounds as the most important odor-active compounds in Dahongpao. The roasting process affects the overall odor characteristics of Dahongpao, and appropriate roasting can enhance its sensory quality. The study provides helpful guidance for the production process of Dahongpao.

Summary: This study evaluated the physiological and metabolic effects of thiamethoxam on tea plants and found that it positively promoted the physiological and metabolic response. Comparison of metabolomics between thiamethoxam-treated and control groups revealed significant differences, with the most perturbation occurring in flavone and flavonol biosynthesis. Thiamethoxam treatment upregulated the levels of beneficial secondary metabolites luteolin and kaempferol, providing protection against biotic and abiotic stresses.

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: Tea, a commercially grown crop for decades, contains essential nutrients and plant secondary metabolites with beneficial health effects. UDP-glycosyltransferases (UGTs) are crucial in creating a variety of glycoconjugates by transferring activated sugar donors to acceptor molecules. Recent efforts to characterise UGTs in C. sinensis have been aided by the sequencing of the tea plant genome, allowing for a better understanding of their physiological role and biotechnological potential. This article identifies UGTs of family 1 in C. sinensis based on conserved PSPG motif and catalytically active histidine, clustering them into 21 groups in a phylogenetic tree, and highlights the current understanding of CsUGTs, as well as discussing future perspectives.

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: This study investigated the chemical characteristics of Jianghua Kucha (JHKC), a special tea germplasm in China, and found that it mainly contains high levels of purine alkaloids and methylated flavanols, as well as low levels of flavonol glycosides. Caffeine metabolism, flavonoid biosynthesis, and flavonol and flavone biosynthesis were identified as the most differential metabolic pathways. JHKC can be a valuable resource for breeding tea cultivars with high contents of theacrine, non-epi-form flavanols, and methylated flavanols.

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: This study used mixed methods to characterize the food environment in informal settlements in Nairobi and examine the factors influencing women's food choices in those environments. The study found a large number of vendors selling various food items, with limited diversity of fruits and relatively expensive animal-source foods. Women's interactions with the food environment were influenced by individual factors such as income, time, convenience, and preferences. The findings suggest that interventions targeting both the external food environment and individual factors such as income are necessary to promote healthy diets among low-income populations in informal settlements in Kenya.

Summary: This study examined trends in the proximity of top-selling quick-service restaurants (QSRs) to public schools in the United States between 2006 and 2018. The findings showed that there was an increase in the number of QSRs near schools with a high percentage of poverty, as well as schools with a higher proportion of Black or African American and Hispanic or Latino students. This has important implications for children's health and diet-related disparities.

Summary: Green roofs are important for urban resilience, but the growth and survival of plants on extensive green roofs are often affected by environmental stresses. Stress-tolerant plants are commonly used to maintain the green roof's services, but introducing less tolerant plant species for food production requires a better understanding of how stress-tolerant species can facilitate the performance of stress-intolerant ones. This study presents a framework that combines trait-environment theory and facilitation ecology to investigate the performance of stress-intolerant species in extensive green roofs.

Summary: In this study, an ionic covalent organic framework (iCOF) surface grafting monolithic sorbent was prepared for in-tube solid-phase microextraction (SPME) of aristolochic acids (AAs) in various samples. The density of quaternary ammonium ions in the iCOF was modulated for enhanced adsorption of AAs. The iCOF surface grafting monolithic sorbent was confirmed by different means. Several operating conditions were optimized to develop the online in-tube SPME-HPLC method, which showed good linearity, low limits of detection, and high recoveries for AAs in serum samples. This study presents a feasible approach for the application of COF-based monolithic sorbents in sample preparation.
