Summary: A mutant variant of Yanling Yinbiancha with green leaves has been identified, which is different from the original albino leaves. Transcriptomic and metabolomic analysis revealed differentially expressed genes and metabolites between the two variants. The differences between green and albino leaves may be associated with the synthesis of anthocyanins, chlorophyll, and carotenoids.

Summary: The young shoots of the tea plant Baiye No. 1 display albino phenotype under low temperatures and re-green during warm season. By sequencing the transcriptome, we constructed competing endogenous RNA regulatory networks involved in response to cold stress, photosynthesis, chlorophyll synthesis, amino acid synthesis, and flavonoid accumulation. These findings provide novel insights into the molecular mechanisms underlying albinism mutants of Baiye No. 1.

Summary: Seasonal greening is an important survival strategy for albino tea cultivars, and CsRVE1 is identified as a nuclear-located Myb-like transcription factor that can positively modulate this process by activating genes involved in light harvesting and chlorophyll biosynthesis. CsRVE1 directly binds to the promoters of these genes and leads to chlorophyll accumulation in tea leaves. The suppression of CsRVE1 decreases the expression of target genes, while its overexpression increases chlorophyll levels and activates related genes in Arabidopsis.

Summary: Pruning is an important strategy for increasing tea production, but its effects on tea quality are not well understood. In this study, the ionomic and metabolomic profiles of tea leaves from Wuyi Mountain were analyzed. Pruning led to significant changes in the ionomic profiles, with decreases in mobile elements and increases in immobile ions. Metabolomic analysis also showed that pruning affected tea leaf metabolism. These findings indicate that pruning affects tea quality mainly through its influence on leaf mineral composition.

Summary: Purple-leaf tea cultivars are known for their specific chemical composition that greatly influences tea bioactivity and plant resistance. Studies have shown that the high anthocyanin and low chlorophyll content contribute to the purple-leaf phenotype, with key genes such as 4CL, ANS, UFGT, and HEME playing crucial roles in the formation of purple leaves. These findings provide insights into the mechanism of purple-leaf formation in tea cultivars.

Summary: This study investigates the metabolic crosstalk between non-volatile and volatile metabolites in tea. The results suggest that the synthesis of these metabolites is potentially connected through shared intermediates, and multiple metabolic regulation modes exist. The study provides important knowledge for rational tea germplasm improvements.

Summary: This study examined the influence of solvent polarity in the solid-liquid extraction of Camellia sinensis var. assamica cv. Zijuan. The results showed that a hydroalcoholic extract with a proportion of 75% ethanol and 25% water had the highest contents of phenolic compounds and chlorophylls, as well as the highest color intensity and antioxidant activity.

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: This study reveals that the UV-B signal regulates the seasonal greening process of albino tea plants by modulating CsHY5-inhibiting chlorophyll biosynthesis. Reduction of solar UV-B promotes the seasonal greening by inhibiting CsHY5 transcription and activating genes involved in light-harvesting and chlorophyll biosynthesis. Indoor supplementary UV-B exposure, on the other hand, reduces chlorophylls by activating CsHY5 and inhibiting chlorophyll biosynthetic genes.

Summary: The present study assessed mycotoxin contamination in Chinese tea samples and determined the relationship between tea consumption and dietary exposure. The results showed that the concentrations of most mycotoxins in tea samples were below the established regulations, except for ochratoxin A in dark tea samples. Risk assessment indicated that there is no dietary risk of exposure to mycotoxins through tea consumption in the Chinese population.

Summary: Selenium acquisition from daily diet can reduce disease risk. The main source of dietary Se is the edible parts of crop plants, which is determined by Se bioavailability in soil. Recent research has focused on the biogeochemical cycle of Se driven by specific microorganisms, emphasizing the oxidizing process. Plant root exudates and rhizosphere microorganisms affect soil Se availability. Beneficial microorganisms, including endophytes, promote crop quality and improve crop tolerance to stresses. Understanding Se transformation along the plant-soil continuum is crucial for agriculture and human health.

Summary: Research has found that albino tea, with its high amino acid content, has attracted attention in the tea market due to its attractive appearance and fresh taste. The study showed that the main amino acid content gradually decreased as the tea plant aged. Principal component analysis revealed that the amino acid content of individual plants became stable with plant growth. Correlation analysis indicated a significant negative correlation between several main amino acids and the contents of chlorophyll a, chlorophyll b, and carotenoids. The results of the study suggest that the accumulation of amino acids in tea plants is closely related to leaf color variation and tree age during the growing period.

Summary: In this study, tea leaf-color mutants were studied using transcriptome and biochemical analysis, and it was found that the reduced chlorophyll content might be caused by the activation of genes related to chlorophyll degradation, along with a reduction in flavonoid biosynthesis and an accumulation of glutamate. These findings provide new insights into the molecular mechanisms underlying leaf-color bud mutation in tea plants.

Summary: Metabolites, especially flavonoids, amino acids, organic acids, and alkaloids, showed distinct seasonal variations in fresh tea shoots of different tea accessions. Key genes and downstream compounds in the flavonoid pathway were lowest in spring, but catechin quality index was highest in this season. Regulatory pathways were explored through metabolite correlation network and weighted gene co-expression network.
