Effect of fluoride on the biosynthesis of catechins in tea [Camellia sinensis (L.) O. Kuntze] leaves
Scientia Horticulturae, 2015Abstract Tea plant, Camellia sinensis, can accumulate high levels of fluoride (F); however, it is unclear how F influences secondary metabolism in tea plants. In this study, two tea cultivars seedlings, Fuyunliuhao (FY) and Wuniuzao (WNZ), were cultivated in nutrient solutions containing different concentrations of F for 4 weeks to investigate the ...

Microbial Technologies in Pest and Disease Management of Tea (Camellia sinensis (L.) O. Kuntze)
2021Tea, the natural beverage prepared from Camellia sinensis (L). O. Kuntze, is the most consumed drink next to water. Commercially grown tea plants are attacked by pest and diseases leading to considerable crop loss. Synthetic pesticides have been the preferred method of pest and disease control in tea cultivation.

Agrobacterium tumefaciens-Mediated genetic transformation in tea (Camellia sinensis [L.] O. Kuntze)
Plant Molecular Biology Reporter, 2004We have developed a system to produce transgenic plants in tea (Camelia sinensis [L.] O. Kuntze) viaAgrobacterium tumefaciens-mediated transformation of embryogenic calli. Cotyledon-derived embryogenic callus cultures were cocultivated with anA. tumefaciens strain (AGL 1) harboring a binary vector carrying the hygromycin phosphotransferase (hpt II ...

Spectral characterization and LAI modelling for the tea ( Camellia sinensis (L.) O. Kuntze) canopy
International Journal of Remote Sensing, 2002Understanding the spectral characteristics of tea plants is important in monitoring tea plantations by remote sensing. Westhall tea estate, Kataboola, situated in the Kandy district in Sri Lanka, was selected as the study site. The Leaf Area Index (LAI) of the tea canopy and spectral reflectance of different types of tea clones for different pruning ...

Characterization of dihydroflavonol 4-reductase cDNA in tea [Camellia sinensis (L.) O. Kuntze]
Plant Biotechnology Reports, 2008Tea leaves are major source of catechins—antioxidant flavonoids. Dihydroflavonol 4-reductase (DFR, EC 1.1.1.219) is one of the important enzymes that catalyzes the reduction of dihydroflavonols to leucoanthocyanins, a key “late” step in the biosynthesis of catechins.

Characterization of fluoride uptake by roots of tea plants (Camellia sinensis (L.) O. Kuntze)
Plant and Soil, 2012Tea plants (Camellia sinensis (L.) O. Kuntze) accumulate high fluoride in the leaves whereas the mechanism on its uptake is poorly understood. The measured F− uptake was compared to calculated uptake from transpiration rates assumuing no discrimination between F− and water to characterize the property of F− absorption by tea plant roots.

Ghrelin was originally described as a growth hormone (GH)-releasing and appetite stimulating hormone in mammals, which is highly conserved and extensively expressed in all eukaryotic organisms investigated. Ghrelin is a natural ligand of the growth hormone secretagogue-receptor, and functions primarily as a GH-releasing hormone and an orexigen, as well

Certain factors associated with blister blight resistance in Camellia sinensis (L.) O. Kuntze
Physiological and Molecular Plant Pathology, 2005The role played by certain factors, physical barriers and chitinase enzyme, associated with blister blight resistance in tea was investigated. The blister blight resistance of the tea clone SA-6 was due to higher amounts of epicuticular wax and increased thickness of cuticle/epidermal layer, functioning as physical barriers to hyphal penetration of ...
