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 ...

Induction of synchronous secondary somatic embryogenesis in Camellia sinensis (L.) O. Kuntze

Journal of Plant Physiology, 2001
Summary Nutritional effect of nitrate salts of potassium and ammonium, together with different concentrations of sulphate salts of aluminium, potassium, magnesium, and ammonium on secondary somatic embryogenesis, wereinvestigated. Nitrate salts of potassium (9.39 mmol/L) and ammonium (10.31 mmol/L) with only 1.5 mmol/L potassium sulphate produced ...

ABA associated biochemical changes during somatic embryo development in Camellia sinensis (L.) O. Kuntze

Journal of Plant Physiology, 2004
The effect of ABA on reserve accumulation in maturing somatic embryos of tea was compared with and without ABA treatment. Changes in the levels of starch, total soluble sugars (TSS), proteins, and phenols were studied in the somatic embryos at different stages of development (globular, heart, torpedo and germinating embryos) in order to investigate ...

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 ...

Isolation and Characterization of Brassinosteroids from Leaves of Camellia sinensis (L.) O. Kuntze

Plant Growth Regulation, 2004
Brassinosteroids are of ubiquitous occurrence in plants and elicit a wide spectrum of physiological responses. In our study, brassinosteroids were isolated and identified in topmost dormant leaves of tea plants. Six brassinosteriods, i.e. 6-deoxocastasterone, 24-epibrassinolide,3-dehydroteasterone, typhasterol, 3-deoxotyphasterol and 28-homodolicholide,

Characterization of dihydroflavonol 4-reductase cDNA in tea [Camellia sinensis (L.) O. Kuntze]

Plant Biotechnology Reports, 2008
Tea 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.

Certain factors associated with blister blight resistance in Camellia sinensis (L.) O. Kuntze

Physiological and Molecular Plant Pathology, 2005
The 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 ...

Immunochemical Identification of Immunoreactive Ghrelin in Tea Plant, Camellia sinensis (L) O. Kuntze

Proceedings of the National Academy of Sciences, India Section B: Biological Sciences, 2017
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
