Comprehensive analysis of carotenoids constituents in purple-coloured leaves and carotenoid-derived aroma differences after processing into green, black, and white tea

Jiang Shi et al.

Summary: This study accurately quantified 3 carotenes and 16 xanthophylls in 15 tea cultivars with leaves of different colors. The tea processing decreased the tea carotenoids by more than 65%, promoting the production of volatile apocarotenoids. Purple tea products were found to contain 25 crucial carotenoid-derived aroma compounds, with alpha/beta-ionone and their derivatives and dihydroactinidiolide accounting for more than 50% of total volatiles, contributing to the fruity aroma in purple tea products.

A comprehensive study of the differences in protein expression and chemical constituents in tea leaves (Camellia sinensis var. sinensis) with different maturity using a combined proteomics and metabolomics method

Zhen Sun et al.

Summary: The maturity of tea leaves affects the quality and price of tea. This study used a combined proteomics and metabolomics analysis to explore the differences in protein expression and metabolites in tea leaves at different maturity levels. The results showed significant differences in nonvolatile components related to various metabolic pathways. Bud leaves had higher levels of enzymes related to the biosynthesis of important compounds, resulting in higher levels of these compounds compared to leaves. The first leaf had higher levels of a specific enzyme, leading to higher levels of a specific compound.

Insights into acylation mechanisms: co-expression of serine carboxypeptidase-like acyltransferases and their non-catalytic companion paralogs

Shengbo Yao et al.

Summary: Serine carboxypeptidase-like acyltransferases (SCPL-ATs) play a crucial role in the galloylation of flavan-3-ols in plants. This study identified two paralogs, CsSCPL4 and CsSCPL5, involved in this process and revealed their different functions, as well as their interaction and evolutionary relationship.

Nontargeted and targeted metabolomics analysis provides novel insight into nonvolatile metabolites in Jianghua Kucha tea germplasm (Camellia sinensis var. Assamica cv. Jianghua)

Wenliang Wu et al.

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.

Neuroprotective Effect of Gallocatechin Gallate on Glutamate-Induced Oxidative Stress in Hippocampal HT22 Cells

Do Hwi Park et al.

Summary: This study investigated the neuroprotective effects of catechins, particularly GCG, against glutamate-induced oxidative stress in mouse hippocampal neuronal HT22 cells. GCG demonstrated strong antioxidant effects, reducing intracellular Ca2+ levels and inhibiting nuclear condensation and ERK/JNK phosphorylation. The neuroprotective mechanism of GCG involved reducing free radicals and intracellular Ca2+ influx, as well as inhibiting ERK and JNK phosphorylation, effectively suppressing neurocytotoxicity induced by glutamate in HT22 cells.

Tissue-Dependent Variation Profiles of Tea Quality-Related Metabolites in New Shoots of Tea Accessions

Hiroto Yamashita et al.

Summary: Our study identified tissue-dependent variation in tea quality-related metabolites in new leaves and stems of tea accessions. The volatile content in tea accessions showed significant variation, indicating a dense network between tea quality-related metabolites, especially in new leaves. These findings are crucial for improving tea quality through metabolic engineering and selection of breeding materials in tea plants.

Nitrogen-Regulated Theanine and Flavonoid Biosynthesis in Tea Plant Roots: Protein-Level Regulation Revealed by Multiomics Analyses

Yan Wang et al.

Summary: Theanine and flavonoids are the major secondary metabolites synthesized in tea plant roots, with nitrogen playing a crucial role in their biosynthesis. This study identified proteins responsive to nitrogen deficiency and found that nitrogen promotes theanine synthesis while repressing flavonoid biosynthesis. The ubiquitylome analysis revealed that key enzymes in theanine and flavonoid biosynthesis are modified by ubiquitination, providing insights into the post-translational regulation of secondary metabolism in tea plants.
