An Improved Protocol for the Isolation of RNA from Roots of Tea (Camellia sinensis (L.) O. Kuntze)
Molecular Biotechnology, 2011Tea, a beverage crop, is a rich source of polyphenols and polysaccharides which greatly attribute to its importance. However, oxidation and precipitation of these compounds during nucleic acids extraction is a limitation to molecular biology and genomic studies.

Zinc Modulates Drought-Induced Biochemical Damages in Tea [Camellia sinensis (L) O Kuntze]
Journal of Agricultural and Food Chemistry, 2013Zinc (Zn) is an essential micronutrient that affects the growth and productivity of tea plant. Drought stress causes various biochemical and physiological damages in plants. The present study aims at understanding the role of Zn in modulating drought stress induced growth and biochemical damages in tea plant.

Phenolics metabolism in boron-deficient tea [Camellia sinensis(L.) O. Kuntze] plants
Acta Biologica Hungarica, 2013Modification in the metabolism of phenolic compounds under boron (B) deficiency conditions was studied in tea plants. Plants were grown from seed, treated with low B in hydroponic medium under environmentally controlled conditions for six weeks. Dry matter production and B content of plants were significantly declined under B deficiency conditions ...

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 ...

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.

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 ...

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.

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 ...

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.
