CaCl2 improves post-drought recovery potential in Camellia sinensis (L) O. Kuntze
Plant Cell Reports, 2010Drought stress affects the growth and productivity of the tea plant. However, the damage caused is not permanent. The present investigation studies the effect of CaCl(2) on antioxidative responses of tea during post-drought recovery. Increase in dry mass, proline and phenolic content of leaf with decrease in H(2)O(2) and lipid peroxidation and ...

In vitro regeneration of Camellia sinensis (L.) O. Kuntze by somatic embryogenesis
Plant Cell Reports, 1995Within 3 weeks of culture, excised cotyledon expiants of Camellia sinensis (L.) O. Kuntze produced somatic embryos without intermediate callus when cultured in Murashige and Skoog's basal medium with 30 g(-1) sucrose. In medium without plant growth regulators, up to 60% of the cultures developed somatic embryos.

Molecular regulation of catechins biosynthesis in tea [Camellia sinensis (L.) O. Kuntze]
Gene, 2012Catechins are bioprospecting molecules present in tea and any effort towards metabolic engineering of this important moiety would require knowledge on gene regulation. These are synthesized through the activities of phenylpropanoid and flavonoid pathways. Expression regulation of various genes of these pathways namely phenylalanine ammonia-lyase (CsPAL)

Boron re-translocation in tea (Camellia sinensis (L.) O. Kuntze) plants
Acta Physiologiae Plantarum, 2013Boron (B) re-translocation is an important factor determining tolerance to B deficiency in plants. In this work growth, B content of leaves with different ages, B partitioning between soluble and cell wall (CW) fractions, and B re-translocation were investigated in tea (Camellia sinensis (L.) O. Kuntze) plants grown hydroponically without (

Somatic Embryogenesis in Tea (Camellia sinensis (L.) O. Kuntze)
1999Tea (Camellia sinensis (L.) O. Kuntze) is the oldest caffeine-containing beverage; it supposedly originated from China and North Eastern region of India. From the earliest times tea was known for its properties as a healthy, refreshing drink and the word ch’a was used in China and India.

In vitro clonal propagation of tea (Camellia sinensis (L.) O. Kuntze)
Plant Cell, Tissue and Organ Culture, 1992A system for in vitro clonal propagation has been developed in tea plants. Shoots obtained from primary explants were induced from terminal buds and axillary buds of mature field-grown plants. Cultures were initiated from both types of explants on Murashige and Skoog (MS) medium supplemented with 10% coconut milk (CM), 200 mg l-1 of yeast extract (YE),

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 ...

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.

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 ...
