Seed development in Camellia sinensis (L.) O. Kuntze

Seed Science Research, 2002
Seed development of tea was studied to identify the maturity index and the optimal time of seed collection. After harvest, the moisture content (28–30%fresh weight basis) of mature seeds, which germinated 100%, declined progressively (19% moisture content) after shedding, with a decrease in seed germination and viability.

In vitro regeneration of Camellia sinensis (L.) O. Kuntze by somatic embryogenesis

Plant Cell Reports, 1995
Within 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, 2012
Catechins 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)

Micropropagation of tea (Camellia sinensis (L.) O. Kuntze) using Thidiazuron

Plant Growth Regulation, 1998
The effect of thidiazuron (TDZ) on the micropropagation of Camellia sinensis (China hybrid) was compared with that of benzylaminopurine (BAP) using nodal segments from in vitro raised seedlings. Extremely low concentrations of TDZ (1pM–100nM) alone were effective in inducing shoot bud proliferation and maintaining high rates of shoot multiplication on ...

In vitro clonal propagation of tea (Camellia sinensis (L.) O. Kuntze)

Plant Cell, Tissue and Organ Culture, 1992
A 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),

Metabolics and ionomics responses of tea leaves (Camellia sinensis (L.) O. Kuntze) to fluoride stress

Plant Physiology and Biochemistry, 2021
Tea plant (Camellia sinensis (L.) O. Kuntze) is known to accumulate high concentrations of fluoride (F) in its leaves; however, the underlying mechanism of F accumulation remains unclear. The main objective of this study was to investigate the homeostatic self-defense mechanisms of tea leaves to F supplementation (0, 5, 20, and 50 mgL-1) by ...

Differential expression of microRNAs in dormant bud of tea [Camellia sinensis (L.) O. Kuntze]

Plant Cell Reports, 2014
Expression analysis of miRNAs and understanding their target genes function in dormant tea bud might be used to identify molecular network panel and novel approaches for modulating dormancy in tea. Tea [Camellia sinensis (L) O. Kuntze, Theaceae] is an important commercial beverage crop manufactured from the apical bud and two leaves immediately below ...

Somatic Embryogenesis in Tea (Camellia sinensis (L.) O. Kuntze)

1999
Tea (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.
