This study was carried out as a prerequisite to evaluate the therapeutic potential of Camellia varieties. The crude extracts of six different plants of green tea Camellia assamica and Camellia sinensis were tested against three Gram-positive and four Gram-negative bacteria using agar disk diffusion method at 50 mg/ml concentration. 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) and dip...

The present experiment is an effort to find a stable reference gene in Camellia sinensis and Camellia assamica under different biotic and abiotic stresses. This study evaluate the variation in gene expression across tea leaf tissues in nine experiments. The suitability of 18S rRNA, 26S rRNA, rubiscobis-phosphatase oxygenase (RuBP) and Camellia tubulin (CaT) as reference genes were validated by ...

Kombucha is a refreshing beverage obtained by the fermentation of sweetened black tea with a „tea fungus“ (symbiotic culture of acetic acid bacteria and yeasts). It is consumed due to its potential beneficial effects on human health. The aim of this study was to investigate activity of Kombucha on human peripheral blood lymphocytes in vitro. We analyzed Kombucha made from different substrates: ...

OBJECTIVES Panax ginseng, Camellia sinensis and bezafibrate were compared for their lipid-lowering, antioxidant and anti-inflammatory properties as potential agents to prevent nonalcoholic fatty liver disease and its progression to nonalcoholic steatohepatitis. METHODS Fifty Wistar rats were randomized into five groups: G1 (feed with standard diet); G2 (feed with high-fat diet with 58% of ene...

Paenibacillus sp. XY044 is an endophytic bacterium isolated from the stem of a tea plant (Camellia sinensis cv. Maoxie). Here, we present the draft genome sequence of XY044, which includes genes encoding features related to plant growth promotion and biocontrol.

OBJECTIVE To evaluate fluoride and aluminum concentration in herbal, black, ready-to-drink, and imported teas available in Brazil considering the risks fluoride and aluminum pose to oral and general health, respectively. METHODS One-hundred and seventy-seven samples of herbal and black tea, 11 types of imported tea and 21 samples of ready-to-drink tea were divided into four groups: I-herbal t...

Tea is one of the most popular beverages across the world and is made exclusively from cultivars of Camellia sinensis. Many wild relatives of the genus Camellia that are closely related to C. sinensis are native to Southwest China. In this study, we first identified the distinct genetic divergence between C. sinensis and its wild relatives and provided a glimpse into the artificial selection of...

This study aimed to evaluate the efficacy of semi fermented and non fermented Camellia sinensis extracts (Black and Green tea) and comparison between them against Streptococcus mutans ATCC 25175, S. mitis ATCC 9811 and S. sanguis ATCC 10556 that are responsible for dental caries and bacteremias following dental manipulations. Minimum inhibitory concentrations of both tea extracts were assessed ...

MADS (Minichromosome Maintenance1 Agamous Deficiens Serum response factor) box genes encode transcription factors and they play a key role in growth and development of flowering plants. There are two types of MADS box genes- Type I (serum response factor (SRF)-like) and Type II (myocyte enhancer factor 2 (MEF2)-like). Type II MADS box genes have a conserved MIKC domain (MADS DNA-binding domain,...
